. It is our hope that this guide will serve to convey the joys of HF and all the benefits of owning and using the TS-480 to whoever reads this guide – whether you have already purchased a TS-480, an accomplished operator, thinking of buying a transceiver, or just thinking of taking up Amateur Radio as a hobby. Design Objectives Determination to create a unique transceiver The concept of a compact HF transceiver first saw the light of day with Kenwood’s TS-50.
From then on, such equipment has become an essential part of the Amateur Radio world. Equipment has now evolved with the appearance of multi-band models. Standalone control panel For mobile operations, a separate control panel is ideal, but what if the transceiver is also to be used as a base station?
This was the problem we faced. With a large desktop rig, it is no easy matter to shift things around to find the best position, so perhaps it would be a good idea to have a separate control panel that could be moved easily. It was with this in mind that Kenwood came up with the idea of an Internet remote-controlled transceiver. You may be away on a business trip, but you want to operate, or you may want to use a large Yagi antenna out in the suburbs from your downtown apartment.
In 1996, when on a visit to the US to promote the TS-570 a local salesman asked whether we were next going to put an AT into the TS-50. Well, perhaps that was where the TS-480 got its start! Achieving 200W output in a compact transceiver In achieving our goal of 200W there was one major constraint –.
In this genre, price is an important factor, so by limiting the TS-480 to HF, we developed what is in fact a compact transceiver that stands apart from the competition. The TS-480 is designed to ensure not only excellent TX performance but also. ● 200W final section Explained here is the circuitry for the 200W final section, the crown jewel of the TS-480 Series. This circuit is responsible for developing 200W output with a DC 13.8V power supply.
Of course, various approaches are possible. The typical one would be to use a high voltage (28V or more) with the FETs in a push-pull arrangement. 1 illustrates TX IM characteristics with 200W output at 14MHz, while the second graph (Fig. 2) charts high-frequency spurious emissions. 1: TX IMD (output 200W) Fig. 2: TX Spurious emissions.
It is possible for them to make use of the 100W unit in their possession. The PS-53 power supply is specified for the TS-480; however, as long as it can produce 20.5A or more continuously at 13.8V, other power supplies can be used. Also, it is possible to operate this transceiver using a single power supply that can produce at least 41A continuously.
It should be pointed out that it is possible to increase the output of these models: the 50W model to 100W, and the 10W model to 50W or 100W. A TS-480 owner who acquires a more advanced license and wants to make use of this capability should go to the nearest service center. Note that it is not possible to upgrade to 200W output. 4: 200W final section Fig. 5: 100W final section with antenna tuner. 10.695MHz crystal, or the modulation was performed by the VCO on the 2nd OSC. The latter was not an option for the TS-480, and since the whole transceiver had to be compact, we did not adopt the former approach.
How then is FM. HFV/UHF that are designed to cover all frequency bands with a single mixer. Since HF50MHz is the “home turf” for the TS-480 Series, it has an advantage as in regards to the operating conditions for the mixer. Since developing the TS-950, Kenwood has exclusively employed J-FET quad mixers, and the TS-480 is no exception. 8 corresponds to these conditions. Under these conditions, if there were interfering signals that were faintly picked up by the other transceivers in this comparison, the strength of those interfering signals would have to rise by 1015dB for the TS-480 to begin suffering the same effects. As with previous models, sensitivity is set to switch at 21.5MHz with the pre-amp on.
However, there is a difference: previously the pre-amp itself was switched, but in the case of the TS-480 this is managed by switching the pre-amp’s NFB gain. Jumpers for joy As with the TS-2000, something special has been provided for both the BPF ATT in the BC band and the regular ATT: The BPF has been equipped with an ATT in order to cope with powerful local broadcasting stations in the BC band. Circuitry after the roofing filter Except for FM, the TS-480 has a double super: 1st IF is 73.095MHz and the 2nd IF is 10.695MHz.
For FM, there is also a triple super as low as 455kHz. This is followed by analog detection and signal processing performed by the AF DSP in a standard arrangement.
Whereas the TS-570 provided only a single slot for installing an optional filter, the TS-480 has two slots, meaning that two of the three filters can be installed at the same time. And the process of installation itself is quite easy: there is no need to remove the main unit, since the option installation unit has been designed to be separately removable. Features useful for 50MHz operations ● You discover a DX CW signal during a USB band search! The TS-480 has a feature that is perfect for such times: you can automatically switch to CW transmission by just keying the transmitter (key down) with your CW key, keyer or CW computer program. TX tuning is a handy feature to have. It outputs a low-power continuous carrier for adjusting a screw-drive or similar antenna.
It allows you to transmit a continuous carrier that is independent of the mode and power of your current operations. Simply assign a PF key to this function. No paddle, but you want to give CW a try?.
Fig.13 is a block diagram illustrating in principle how the DNL operates. 13: Principle of DNL operation The digital signal processor equipped on the TS-480 is the 16-bit fixed-point TMS320VC5402 from Texas Instruments, which offers excellent value for the money. Running at 100MHz, it. Because the TS-480 will be often used for mobile operations, DNL parameters have been tuned so as to have maximum effect on ignition noise.
However, even when used as a fixed station, it can be very effective on irregular, unanticipated noise, so we recommend that you try making use of it, in combination with the noise blanker as well. 15: NR OFF Fig. 16: NR1 ON Fig.
Beat cancel ● Beat cancel (BC), as its name implies, is designed to cancel unpleasant beat interference. Like NR1, it uses adaptive filter technology, tracking a beat and canceling it by shaping. It is very similar to a band elimination filter.
Even if there are multiple beats, BC can track and cancel them all. However, since BC operates at the AF stage, should powerful beat interference be experienced during DX operations, even though beat cancel works properly, by then the AGC has already attenuated both the interference and the target signal. RX DSP filters ● In SSB, AM and FM modes, you can independently set high- and low-cut frequencies for the AF filters to suit operating conditions (slope tune). 20 illustrates how slope tune works.
When there are interfering signals in proximity to the target signal, you can use a high-cut filter and a low-cut filter to remove the signals above and below the target. WIDTH 250 500 1000 1500 When the optional CW filters are installed, the TS-480 will automatically select the optimum IF filter in accordance with the DSP filter bandwidth.
Also available are filters for PSK31 and RTTY data mode operations. From the menu, if you select ON for the “Available data communications filters”, these data communications filters can be used. If you use the RX equalizer it is easy to adjust RX audio quality. Take your pick from flat (default), high boost, Formant pass, bass boost, and conventional settings. As a new feature, the TS-480 actually offers two types of high boost and two types of bass boost. As with other Kenwood HF transceivers, the TS-480 provides menu access to its many features.
By selecting and adjusting these features, you can customize the TS-480 so that it fits perfectly into your way of operating a radio. Introduced here are tips on how to get the most out of the various items listed in the menus.
Transverter. Unlike the TS-570, you can set any frequency. Transverter output is fixed at 5W for the TS-570, but with the TS-480 you can choose output freely (within the transmitter’s capability). It can also reduce low-frequency interference. If you own an AT-300, you can connect it to the TS-480; however, operation is limited by the capabilities of the AT-300. You can control the linear amp independently for the HF and 50MHz bands.
You can adjust FM mic gain (3 levels) This enables you to pick the appropriate DSP filter for data communications using the filter switch on the control panel. Adjust input and output levels independently when the TS-480 is connected to a SoundBlaster™ card or other external device.

The squelch can be forced open for as long as the PF key is depressed. Useful for monitoring when setting CTCSS, etc.
The TS-480 will receive using the widest passband available in that mode for as long as the PF key is depressed. This is a quick way to check on nearby interference. TF-SET Q MR Q MI SPLIT SCAN M V M.IN CW TUNE FINE ANT 1/2 You can assign a function you often use to a PF key on the mic. Also, a function defined by pressing the key for 1 second can be called up instantly. Consequently, the menu system can be a little inconvenient when you need to change several settings at once.
To solve this problem, the TS-480 offers two sets of menus: A and B. Switching between these can greatly simplify operations – for example, when switching from DX to local, from regular to data communications, or from fixed station to mobile operations. Structural Features Internal structure of the main unit ● The internal structure of the main unit is straightforward: employing a die-cast aluminum chassis, it is designed so that the circuit boards are attached from both above and below. From above one can see the TX/RX unit, the filter unit and the relay unit. As you can tell from this diagram, the cooling fans located at the rear must be powerful enough to be able to suck in fresh air through the intakes on the front panel. In order to make the TS-480 as compact as possible the mounting density of the internal components has been increased.
In the case of the TS-480, in order to make the transceiver compact we provided a single row of tall, highly efficient cooling fins right above the final transistors. This compensated for the lack of cooling fins dictated by the design restrictions. Now let’s have a look at the rise in temperature of the different parts when the TS-480HX transmits continuously (14MHz) for 30 minutes at 200W.
To provide a comparison, plotted on the same graph is test data compiled for a compact 100W model (designed so as not to power-down during continuous transmission at 100W). Despite the fact that the TS-480 Series is compact, it has the same heavy-duty specifications as the previous, fixed station model. Nevertheless, electronic components, whether from Kenwood or another manufacturer, are generally susceptible to heat: the higher the temperature, the shorter is their working life. As explained in the section on development objectives, we started out with the premise that the TS-480 would not be limited to mobile applications but that it would be able to serve as a reasonably priced 200W fixed station. So rather than going for a simple appearance, we decided on a standalone control panel in order to provide true operating ease. There is thus no need to sit in front of the mic and actually repeat your message over and over again. Even when you use a microphone with low sensitivity to record a message, the TS-480 is designed to set the appropriate recording level.
Normally, this recording level is automatically linked to the mic gain setting, so if you wish to adjust recording level manually, you should adjust mic gain while recording is in standby. (using menu #48) to #62, by switching to Voice2 you can hear the S-meter level being read out.
Introduced here are a few of the benefits of the TS-480 Voice Guide. Some of these are automatic, while others are accessed by the PF keys. 1 – 3 Other features This is not connected with the Voice Guide, but the TS-480 is also equipped with a feature that has proved popular on previous models – namely, it issues a beep that serves as an SWR alert when an error is detected in Morse mode with AT tune. Click Enc./Step. (Step no.) Note that if the TS-480 is currently in a configuration mode, these actions will effectively change the settings. But in this case a message is displayed, so you can exit from configuration mode before continuing. Changing memory and registered details You can change any registration data from the appropriate window.

You use this window when storing new data in memory. Display the frequency you wish to register and press M.IN. Then pick the channel (0-89) you want to write to and press DISP: the memory window (right) will open. 2 computers, the remote one having ARCP installed and the host computer having ARHP installed. The basic arrangement is to connect the TS-480 to a host computer, which is on a LAN, and to install ARHP-10 on this computer. ARCP-480 is then installed on the remote computer.
TS-480 installed on the host end might go into continuous transmission accidentally. By setting the time-out timer on the TS-480, it is possible to ensure that, after the set time period has passed, the transceiver will automatically switch back to RX mode.
The timer count always starts with the commencement of transmission, so even in the case of a prolonged but intentional transmission, after the set period has passed it will switch back to RX. communications and the operating system on either end is compatible, check the Voice box.
(It is possible to enter the description using double-byte characters. For the address, it is also possible to enter the domain name, provided that it can be resolved by DNS.) Once you have finished, return to the setup window, select the other computer in the To: combo box, and check the box labeled Use. Using a broadband router Many people using the Internet today use a broadband router (hereafter referred to simply as a router), but in order to use KNS in a setup that has routers installed at both the host and remote ends, you need to configure each end separately. For the MIC terminal wiring diagram, please refer to the instruction manual. If using the MIC terminal, you will need a cable in order to hear the audio received by the TS-480; this connects the transceiver’s EXT-SP terminal to the input terminal on the PC sound card. This completes the setup: the host is now ready for the remote PC user to make a connection. Once the audio cable has been made up, connect the various cables to your PC as illustrated below.
In addition, connect your PC to the TS-480 with an RS-232 cable. Troubleshooting ● Listed below are typical problems that you might encounter. Network & Operations Problem Is it possible to use an analog dial-up connection? I have broadband but is it compatible? Can I use my router with KNS? With a high-speed modem connected directly to my PC running Windows®. I cannot get KNS to work over the Internet connection that is provided as a collective service to my apartment block.
Can I use a software-based firewall? I want to time-out TX after a set time. Is KNS compatible with digital communications (PSK31, SSTV, etc.)? Is KNS compatible with full. Sound Problem The sound does not get through (host PC).
The sound does not get through (remote PC). Solution First check that the audio cable is connected properly.
Check what audio input method (MIC/EXP-SP or DATA) has been selected for the transceiver. TX/RX audio breaks up, is distorted or faint. Check that the computer can produce sound; update drivers as necessary.
Connect a microphone to the computer and bring up the recording control window. Check that the input terminal you are using is active and that it is set to an appropriate level.

SUPPLIED ACCESSORIES After carefully unpacking the transceiver, identify the items listed in the table below. We recommend you keep the box and packing materials in case you need to repack the transceiver in the future. Please observe the following precautions to prevent fire, personal injury, and transceiver damage:. Connect the transceiver only to a power source described in this manual or as marked on the transceiver itself.
Route all power cables safely. Ensure the power cables can neither be stepped upon nor pinched by items placed near or against the cables. Pay particular attention to locations near AC receptacles, AC outlet strips, and points of entry to the transceiver. Take care not to drop objects or spill liquid into the transceiver through enclosure openings. Metal objects, such as hairpins or needles, inserted into the transceiver may contact voltages resulting in serious electrical shocks. Never permit children to insert any objects into the transceiver.
Do not attempt to defeat methods used for grounding and electrical polarization in the transceiver, particularly involving the power input cable. Adequately ground all outdoor antennas for this transceiver using approved methods.
Grounding helps protect against voltage surges caused by lightning. It also reduces the chance of a build-upof static charge. EXAMPLE OF ANTENNA GROUNDING ANTENNA LEAD IN GROUND WIRE CLAMP ANTENNA DISCHARGE UNIT GROUNDING CONDUCTORS ELECTRIC SERVICE GROUND CLAMPS POWER SERVICE EQUIPMENT GROUNDING ELECTRODE SYSTEM. Minimum recommended distance for an outdoor antenna from power lines is one and one-halftimes the vertical height of the associated antenna support structure. This distance allows adequate clearance from the power lines if the support structure fails for any reason. Locate the transceiver so as not to interfere with its ventilation.
Do not place books or other equipment on the transceiver that may impede the free movement of air. Allow a minimum of 10 cm (4 inches) between the rear of the transceiver and the wall or operating desk shelf. Do not use the transceiver near water or sources of moisture. For example, avoid use near a bathtub, sink, swimming pool, or in a damp basement or attic. The presence of an unusual odor or smoke is often a sign of trouble. Immediately turn the power OFF and remove the power cable. Contact a KENWOOD service station or your dealer for advice.
Locate the transceiver away from heat sources such as a radiator, stove, amplifier or other devices that produce substantial amounts of heat. Do not use volatile solvents such as alcohol, paint thinner, gasoline or benzene to clean the cabinet of the transceiver. Use a clean cloth with warm water or a mild detergent. Disconnect the input power cable from the power source when the transceiver is not used for long periods of time.
Remove the transceiver’s enclosure only to do accessory installations described in this manual or accessory manuals. Follow provided instructions carefully, to avoid electrical shocks. If unfamiliar with this type of work, seek assistance from an experienced individual, or have a professional technician do the task. Enlist the services of qualified personnel in the following cases: a) The power supply or plug is damaged. B) Objects have fallen or liquid has spilled into the transceiver.
C) The transceiver has been exposed to rain. D) The transceiver is operating abnormally or performance has seriously degraded. E) The transceiver has been dropped or the enclosure damaged. Do not attempt to perform any kind of configuration or menu setup configuration while driving your car. Do not wear headphones while driving.
Install the transceiver in a safe and convenient position inside of your vehicle so as not to subject yourself to danger while driving. Consult your car dealer for the transceiver installation to ensure safety.
HF/ 50 MHz mobile antennas are larger and heavier than VHF/ UHF antennas. Therefore, use a strong and rigid mount to safety and securely install the HF/ 50 MHz mobile antenna.

INSTALLATION MOBILE INSTALLATION When you use this transceiver for mobile operation, do not attempt to perform any kind of configuration or menu setup configuration while driving your car; it is simply too dangeous. Stop the car and then perform transceiver configuration.
In addition, do not wear headphones while driving. You should install the transceiver in a safe and convenient position inside your vehicle so as not to subject yourself to danger while driving. For example, install the transceiver under the dash in front of the passenger seat so that knees or legs will not strike the transceiver if you brake suddenly. Additionally, do not install the transceiver and its accessories on to the air bag lids. We recommend you consult your car dealer for the transceiver installation to ensure safety.

1 INSTALLATION DC POWER CABLE CONNECTION Connect the DC power cable directly to the vehicle’s battery terminals using the shortest route. Do not use the cigarette lighter socket! The current rating of the cigarette lighter socket is too small to operate the transceiver. Ensure to use a 12 V vehicle battery which has sufficient current capacity. If the current is insufficient, the display may darken during transmission or the trasceiver may work intermittiently.
If you use the transceiver for a long period when the vehicle battery has not been fully charged or when the engine has been stopped, the battery may become discharged in a short time and will not have sufficient reserves to start the engine. Avoid using the transceiver under these conditions. Keep in mind that the TS-480SATtransceiver draws a peak current of approximately 20.5 A and the TS-480HXtransceiver draws a peak current of approximately 41A (20.5A + 20.5A) during transmission. Attach the line filter(s) to the DC cable(s) as shown after the installation (E-typeonly). Note: E-typeonly Do not use two separate batteries to connect each DC cables from the transceiver (TS-480HX).The DC voltage difference between DC IN 1 and DC IN 2 connectors at the transceiver must be within DC 1.0 V to operate the transceiver. Two supplied DC cables (or two optional PG-20DC cables) must be used. Using different length and/ or different gauged cable could result in a voltage difference between DC IN 1 and DC IN 2 connectors at the transceiver (TS-480HX).
ANTENNA CONNECTION In general, HF/ 50 MHz mobile antennas are larger and heavier than VHF/ UHF antennas. Therefore, use a strong and rigid mount to safety and securely install the HF/ 50 MHz mobile antenna. A bumper mount is recommended for stable mounting. However, most recent models of vehicles have plastic bumpers. For such vehicles, ground the antenna mount to the body chassis with a large wire.
Antenna installation is critical for successful mobile operation. For further information, refer to The Radio Amateur’s Handbook, Radio Handbook, or other published texts. GROUND CONNECTION The ground, which is the other half of the antenna system, is very important when using a mobile whip type antenna. Connect the feed line ground for the antenna securely to the vehicle’s chassis, and be certain to bond (electrically connect) the vehicle’s body to chassis. The sheet metal will provide the primary ground plane, so be sure to establish a good RF connection from the feed line to both the chassis and the body.
For comprehensive information on mobile antennas installations and optimization, refer to the ARRL Handbook or similar publications. IGNITION NOISE This transceiver has been equipped with a Noise Blanker and Digital Noise Limiter to filter ignition noises out.
However, some cars may generate excessive ignition noise. If there is excessive noise, use suppressor spark plugs (with resisters), and/ or DC line filters to reduce the electric noises. The ARRL Handbook, or similar refereneces, has a wealth of information regarding this topic. Note: After installation and wiring are completed, confirm that all work has been done correctly, then connect the DC power cable plug(s) to the transceiver. If the fuse blows, disconnect the DC power cable plug(s) from the transceiver immediately, then check all the DC power cables to find the reasons of the short circuit. The DC cable may be damaged, short circuited, pinched, or squashed. After resolving the problem, replace the fuse with one of the same type and rating.
Do not remove the fuse holder for any reason.
. It is our hope that this guide will serve to convey the joys of HF and all the benefits of owning and using the TS-480 to whoever reads this guide – whether you have already purchased a TS-480, an accomplished operator, thinking of buying a transceiver, or just thinking of taking up Amateur Radio as a hobby. Design Objectives Determination to create a unique transceiver The concept of a compact HF transceiver first saw the light of day with Kenwood’s TS-50. From then on, such equipment has become an essential part of the Amateur Radio world.
Equipment has now evolved with the appearance of multi-band models. Standalone control panel For mobile operations, a separate control panel is ideal, but what if the transceiver is also to be used as a base station? This was the problem we faced. With a large desktop rig, it is no easy matter to shift things around to find the best position, so perhaps it would be a good idea to have a separate control panel that could be moved easily. It was with this in mind that Kenwood came up with the idea of an Internet remote-controlled transceiver. You may be away on a business trip, but you want to operate, or you may want to use a large Yagi antenna out in the suburbs from your downtown apartment. In 1996, when on a visit to the US to promote the TS-570 a local salesman asked whether we were next going to put an AT into the TS-50.
Well, perhaps that was where the TS-480 got its start! Achieving 200W output in a compact transceiver In achieving our goal of 200W there was one major constraint –. In this genre, price is an important factor, so by limiting the TS-480 to HF, we developed what is in fact a compact transceiver that stands apart from the competition. The TS-480 is designed to ensure not only excellent TX performance but also. ● 200W final section Explained here is the circuitry for the 200W final section, the crown jewel of the TS-480 Series.
This circuit is responsible for developing 200W output with a DC 13.8V power supply. Of course, various approaches are possible. The typical one would be to use a high voltage (28V or more) with the FETs in a push-pull arrangement.
1 illustrates TX IM characteristics with 200W output at 14MHz, while the second graph (Fig. 2) charts high-frequency spurious emissions. 1: TX IMD (output 200W) Fig. 2: TX Spurious emissions.
It is possible for them to make use of the 100W unit in their possession. The PS-53 power supply is specified for the TS-480; however, as long as it can produce 20.5A or more continuously at 13.8V, other power supplies can be used. Also, it is possible to operate this transceiver using a single power supply that can produce at least 41A continuously. It should be pointed out that it is possible to increase the output of these models: the 50W model to 100W, and the 10W model to 50W or 100W. A TS-480 owner who acquires a more advanced license and wants to make use of this capability should go to the nearest service center. Note that it is not possible to upgrade to 200W output. 4: 200W final section Fig.
5: 100W final section with antenna tuner. 10.695MHz crystal, or the modulation was performed by the VCO on the 2nd OSC. The latter was not an option for the TS-480, and since the whole transceiver had to be compact, we did not adopt the former approach. How then is FM. HFV/UHF that are designed to cover all frequency bands with a single mixer. Since HF50MHz is the “home turf” for the TS-480 Series, it has an advantage as in regards to the operating conditions for the mixer. Since developing the TS-950, Kenwood has exclusively employed J-FET quad mixers, and the TS-480 is no exception.
8 corresponds to these conditions. Under these conditions, if there were interfering signals that were faintly picked up by the other transceivers in this comparison, the strength of those interfering signals would have to rise by 1015dB for the TS-480 to begin suffering the same effects. As with previous models, sensitivity is set to switch at 21.5MHz with the pre-amp on. However, there is a difference: previously the pre-amp itself was switched, but in the case of the TS-480 this is managed by switching the pre-amp’s NFB gain. Jumpers for joy As with the TS-2000, something special has been provided for both the BPF ATT in the BC band and the regular ATT: The BPF has been equipped with an ATT in order to cope with powerful local broadcasting stations in the BC band. Circuitry after the roofing filter Except for FM, the TS-480 has a double super: 1st IF is 73.095MHz and the 2nd IF is 10.695MHz.
For FM, there is also a triple super as low as 455kHz. This is followed by analog detection and signal processing performed by the AF DSP in a standard arrangement. Whereas the TS-570 provided only a single slot for installing an optional filter, the TS-480 has two slots, meaning that two of the three filters can be installed at the same time.
And the process of installation itself is quite easy: there is no need to remove the main unit, since the option installation unit has been designed to be separately removable. Features useful for 50MHz operations ● You discover a DX CW signal during a USB band search!
The TS-480 has a feature that is perfect for such times: you can automatically switch to CW transmission by just keying the transmitter (key down) with your CW key, keyer or CW computer program. TX tuning is a handy feature to have. It outputs a low-power continuous carrier for adjusting a screw-drive or similar antenna. It allows you to transmit a continuous carrier that is independent of the mode and power of your current operations.
Simply assign a PF key to this function. No paddle, but you want to give CW a try?. Fig.13 is a block diagram illustrating in principle how the DNL operates. 13: Principle of DNL operation The digital signal processor equipped on the TS-480 is the 16-bit fixed-point TMS320VC5402 from Texas Instruments, which offers excellent value for the money. Running at 100MHz, it. Because the TS-480 will be often used for mobile operations, DNL parameters have been tuned so as to have maximum effect on ignition noise.
However, even when used as a fixed station, it can be very effective on irregular, unanticipated noise, so we recommend that you try making use of it, in combination with the noise blanker as well. 15: NR OFF Fig. 16: NR1 ON Fig. Beat cancel ● Beat cancel (BC), as its name implies, is designed to cancel unpleasant beat interference. Like NR1, it uses adaptive filter technology, tracking a beat and canceling it by shaping.
It is very similar to a band elimination filter. Even if there are multiple beats, BC can track and cancel them all. However, since BC operates at the AF stage, should powerful beat interference be experienced during DX operations, even though beat cancel works properly, by then the AGC has already attenuated both the interference and the target signal. RX DSP filters ● In SSB, AM and FM modes, you can independently set high- and low-cut frequencies for the AF filters to suit operating conditions (slope tune). 20 illustrates how slope tune works. When there are interfering signals in proximity to the target signal, you can use a high-cut filter and a low-cut filter to remove the signals above and below the target.
WIDTH 250 500 1000 1500 When the optional CW filters are installed, the TS-480 will automatically select the optimum IF filter in accordance with the DSP filter bandwidth. Also available are filters for PSK31 and RTTY data mode operations. From the menu, if you select ON for the “Available data communications filters”, these data communications filters can be used. If you use the RX equalizer it is easy to adjust RX audio quality.
Take your pick from flat (default), high boost, Formant pass, bass boost, and conventional settings. As a new feature, the TS-480 actually offers two types of high boost and two types of bass boost. As with other Kenwood HF transceivers, the TS-480 provides menu access to its many features. By selecting and adjusting these features, you can customize the TS-480 so that it fits perfectly into your way of operating a radio. Introduced here are tips on how to get the most out of the various items listed in the menus. Transverter. Unlike the TS-570, you can set any frequency.
Transverter output is fixed at 5W for the TS-570, but with the TS-480 you can choose output freely (within the transmitter’s capability). It can also reduce low-frequency interference. If you own an AT-300, you can connect it to the TS-480; however, operation is limited by the capabilities of the AT-300. You can control the linear amp independently for the HF and 50MHz bands. You can adjust FM mic gain (3 levels) This enables you to pick the appropriate DSP filter for data communications using the filter switch on the control panel. Adjust input and output levels independently when the TS-480 is connected to a SoundBlaster™ card or other external device.

The squelch can be forced open for as long as the PF key is depressed. Useful for monitoring when setting CTCSS, etc.
The TS-480 will receive using the widest passband available in that mode for as long as the PF key is depressed. This is a quick way to check on nearby interference. TF-SET Q MR Q MI SPLIT SCAN M V M.IN CW TUNE FINE ANT 1/2 You can assign a function you often use to a PF key on the mic. Also, a function defined by pressing the key for 1 second can be called up instantly. Consequently, the menu system can be a little inconvenient when you need to change several settings at once.
To solve this problem, the TS-480 offers two sets of menus: A and B. Switching between these can greatly simplify operations – for example, when switching from DX to local, from regular to data communications, or from fixed station to mobile operations. Structural Features Internal structure of the main unit ● The internal structure of the main unit is straightforward: employing a die-cast aluminum chassis, it is designed so that the circuit boards are attached from both above and below. From above one can see the TX/RX unit, the filter unit and the relay unit.
As you can tell from this diagram, the cooling fans located at the rear must be powerful enough to be able to suck in fresh air through the intakes on the front panel. In order to make the TS-480 as compact as possible the mounting density of the internal components has been increased. In the case of the TS-480, in order to make the transceiver compact we provided a single row of tall, highly efficient cooling fins right above the final transistors. This compensated for the lack of cooling fins dictated by the design restrictions. Now let’s have a look at the rise in temperature of the different parts when the TS-480HX transmits continuously (14MHz) for 30 minutes at 200W. To provide a comparison, plotted on the same graph is test data compiled for a compact 100W model (designed so as not to power-down during continuous transmission at 100W).
Despite the fact that the TS-480 Series is compact, it has the same heavy-duty specifications as the previous, fixed station model. Nevertheless, electronic components, whether from Kenwood or another manufacturer, are generally susceptible to heat: the higher the temperature, the shorter is their working life. As explained in the section on development objectives, we started out with the premise that the TS-480 would not be limited to mobile applications but that it would be able to serve as a reasonably priced 200W fixed station. So rather than going for a simple appearance, we decided on a standalone control panel in order to provide true operating ease. There is thus no need to sit in front of the mic and actually repeat your message over and over again. Even when you use a microphone with low sensitivity to record a message, the TS-480 is designed to set the appropriate recording level.
Normally, this recording level is automatically linked to the mic gain setting, so if you wish to adjust recording level manually, you should adjust mic gain while recording is in standby. (using menu #48) to #62, by switching to Voice2 you can hear the S-meter level being read out. Introduced here are a few of the benefits of the TS-480 Voice Guide. Some of these are automatic, while others are accessed by the PF keys. 1 – 3 Other features This is not connected with the Voice Guide, but the TS-480 is also equipped with a feature that has proved popular on previous models – namely, it issues a beep that serves as an SWR alert when an error is detected in Morse mode with AT tune.
Click Enc./Step. (Step no.) Note that if the TS-480 is currently in a configuration mode, these actions will effectively change the settings. But in this case a message is displayed, so you can exit from configuration mode before continuing.
Changing memory and registered details You can change any registration data from the appropriate window. You use this window when storing new data in memory. Display the frequency you wish to register and press M.IN.
Then pick the channel (0-89) you want to write to and press DISP: the memory window (right) will open. 2 computers, the remote one having ARCP installed and the host computer having ARHP installed. The basic arrangement is to connect the TS-480 to a host computer, which is on a LAN, and to install ARHP-10 on this computer. ARCP-480 is then installed on the remote computer. TS-480 installed on the host end might go into continuous transmission accidentally. By setting the time-out timer on the TS-480, it is possible to ensure that, after the set time period has passed, the transceiver will automatically switch back to RX mode. The timer count always starts with the commencement of transmission, so even in the case of a prolonged but intentional transmission, after the set period has passed it will switch back to RX.
communications and the operating system on either end is compatible, check the Voice box. (It is possible to enter the description using double-byte characters. For the address, it is also possible to enter the domain name, provided that it can be resolved by DNS.) Once you have finished, return to the setup window, select the other computer in the To: combo box, and check the box labeled Use. Using a broadband router Many people using the Internet today use a broadband router (hereafter referred to simply as a router), but in order to use KNS in a setup that has routers installed at both the host and remote ends, you need to configure each end separately. For the MIC terminal wiring diagram, please refer to the instruction manual.
If using the MIC terminal, you will need a cable in order to hear the audio received by the TS-480; this connects the transceiver’s EXT-SP terminal to the input terminal on the PC sound card. This completes the setup: the host is now ready for the remote PC user to make a connection. Once the audio cable has been made up, connect the various cables to your PC as illustrated below.
In addition, connect your PC to the TS-480 with an RS-232 cable. Troubleshooting ● Listed below are typical problems that you might encounter. Network & Operations Problem Is it possible to use an analog dial-up connection? I have broadband but is it compatible? Can I use my router with KNS? With a high-speed modem connected directly to my PC running Windows®. I cannot get KNS to work over the Internet connection that is provided as a collective service to my apartment block.
Can I use a software-based firewall? I want to time-out TX after a set time. Is KNS compatible with digital communications (PSK31, SSTV, etc.)? Is KNS compatible with full. Sound Problem The sound does not get through (host PC).
The sound does not get through (remote PC). Solution First check that the audio cable is connected properly. Check what audio input method (MIC/EXP-SP or DATA) has been selected for the transceiver.
TX/RX audio breaks up, is distorted or faint. Check that the computer can produce sound; update drivers as necessary. Connect a microphone to the computer and bring up the recording control window. Check that the input terminal you are using is active and that it is set to an appropriate level.
