Kenwood TK-805 Modification for Repeater or Link Use Dwayne Kincaid WD8OYGThis document describes the modifications to a Kenwood TK-805 for use in a link or repeater system. The connections shown were to configure the radio as a fixed frequency remote base for a CAT-400 controller. The same techniques can be used for other controllers or repeaters.The TK-805 is a compact 16 channel UHF transceiver that is useable in the amateur bands with no modification. They make good link or remote base radios since they are field programmable with no special cables or software needed for programming. Even though there are 16 channels, for repeater or link use, only channel 1 will be used.While no microphone will be need for use after the modifications, you will need a mic to program and test. If you didn’t get a mic with your unit, you may be able to borrow one for the testing and programming. If you plan on using a few of these radios in your system, you may want to keep one mic.The transmitter is rated at 25 watts and many of the radios have will output somewhat more than 25 watts. However, it would be recommended that no more than 10 watts be used if being used with a repeater or link system. The minimum adjustable power level is about 3 watts. A chart with the amperage required for different RF power levels is near the end of this document.The basic procedure for adding the interface is fairly straightforward. The unit will be disassembled, the interface cable will be added, the unit will be re-assembled, tested and put into service.The first thing that should be done (as with any conversion) is to make sure the radio works. These modifications take about an hour or two and it would be a big waste of time to complete them only to find out that the radio did not work in the first place.If you do not know what frequency the radio is on, skip down to the programming section to see how to view the frequency.If you have the service manual for the radio, the chart below shows where the connections will be made. If you do not have the service manual, just follow the directions below and it should all work.ColorNoteConnectionSignalDB-9RX COR CN202 Pin 4 1 Black 5V, 0V COR present RX CTCSS W201 Pin 4 2 Brown 0V, 5V Tone Present TX PTT J201 Pin 3 3 Red Gnd to PTTTX audio J201 Pin 5 4 Orange MicRX Audio CN202 Pin 5 5 Yellow Rx Audio8 VioletGround1PinCN202GndFor the connection to the CAT-400, we followed the DB-9 pin definitions from the controller’s manual. For the same configuration, you will need a one foot cable with a Male DB-9 connector on one end. Cutting a three foot cable in half works well.For the colors shown above please note that these were the colors for the particular cable that we happened to have. Use a continuity checker to make sure that your cable follows the same color to pin assignment.This photo shows a top view of the finished unit with the DB-9 connector.Some notes: The RX COR and CTCSS are low level signals. They are fine to run to a controller that monitors the level. However, there is not enough drive from these signals to drive a relay or other higher current devices. If you need to drive a high current device, use an appropriate buffer.The CTCSS output does not mute the RX Audio. The CTCSS output is just an indicator if there is a proper tone present or not. The RX Audio will be present on any signal that opens the squelch whether or not there is a tone. If your controller has an “And” function, use that setting.The volume control will have no effect on the RX Audio output to the controller. When the mods are finished, the volume control will only adjust the local volume going to the speaker.Before starting to disassemble the radio, be sure your work space is clean. There are a dozen or so screws, so have a good place to store them to keep them from becoming lost. The tools needs are a small Philips screwdriver, small pliers and small solder iron. Tweezers or hemostats will be helpful.Disassembly:1) Remove the lid (side with speaker). There are two screws. Lift up on the rear of the lid, then pull toward the back.2) Disconnect speaker. Remove the speaker bracket.3) Lift up the DC power cord retainer.4) Turn the unit over. Remove the bottom cover. There are two screws.5) Unsolder speaker jack and discard. It’s a little tough to get the jack out as it’s a tight fit. Needle nose pliers may be needed. Add jumper to pins 2 and 3 activate the speaker (it’s good for monitoring). Pin 1 of the jack is ground and closest to the back of the unit. Later, the link cable will use this entrance where the speaker jack was.6) Remove knobs. (2).7) Remove screws holding the front plastic cover, 4 screws.8) Remove the front plastic cover. There are four tabs that hold the cover to the front panel chassis. Be careful not to break the tabs.9) Remove foam. On the older units, this foam will deteriorate somewhat. If that has happened in your unit, just clean it all out and throw it away. This would be a good time to clean the front plastic cover. Soap and water is good.10) Remove nuts and washers for the two controls. (2)11) Remove LCD screw and LCD. The LCD just pulls straight toward the front and it will come out of it connector.12) Remove front panel chassis screws (4) and the front panel chassis.13) Remove the 2 screws holding the front panel PC board.14) Remove the front panel PCB. It also pulls straight forward and it only held by two connectors. A small screwdriver may help to gently pry it out of the connector.15) Disconnect the cable going from the front panel PC board to the Tone board. The disconnect point is at the Tone board.This finishes the disassembly. All of the connections go on the front panel PC board which is now completely removed from the unit. You will come back to this point and work backward when putting the unit back together.Adding the mods:Route the DB-9 cable through the speaker jack hole now. It’s easy to forget this.Strip off 6” of the outer plastic of the DB-9 cable. This will leave 9 wires (and sometimes on drain). Strip 1/8” off from each wire. This would be the time to check the color coding of the wire to the pin number. If your cable is different, make a note of which color goes to which pins.Cut off the unused wires (including the drain). Be careful with pin 9 when using CAT controller. This has +12 volts on it. Even though this wire is not used, do not just cut it and leave it floating around. Any unused wires with DC power should be capped with a small amount of heat shrink to keep it from shorting to something you don’t want it to. If you don’t know where the unused wires go, cap all of them.Install the COR, RX Audio and Ground wires to CN202. This is the on the front side of the front panel PC board.Flip the board to the other side and install the PTT and TX Audio wires.Then add the RX CTCSS wire.Flip panel back, route wires, tie wrap wires and link cable.Re-assemble. Be careful not to pinch the wires when putting the metal front panel chassis back on.Programming.Turn off radio. Move CN7 to left side (as looking at front display). Turn on radio.Dial in receive freq. Click Mic.Receive Tone. Click Mic.TX Freq. Click Mic.TX Tone. Click Mic.Click mic to reach end of 16 channels.Turn off radio. Move CN7 to right. Turn on radio. Check programming with another radio.Adjustments: Set RF power to 10 watts or lower with VR5 (for use with link or repeater). Adjust TX Freq with TXCO trimmer.Power consumption, 13.8 VDCWatts Amps25 6.010 3.55 2.73 2.2RX 0.25CTCSS Note: The CTCSS on the TK-805s are pretty slow. The rise time will be in the 50 to 100 mSec range, but the fall time can be 250 mSec or more. Take this into consideration if you are building a link system.Buying TK-805s: You can still find a few 805s on e-bay for about $100. If you already have one mic, then you don’t have to worry about if it’s included or not. If you need to buy one, they can be found used for about $20. Also, the power cable is usually missing, but you are wiring into your own power supply, so you won’t need the 10 foot cable that comes with it. You may or may not get a mounting bracket, but those are also available in the used market for about $10.Many used units have a crack in the plastic front panel cover on either side. This is pretty much normal. They all crack there sooner or later. It won’t affect the mods or the operation at all.。

(any PF key can be programmed for emergency use).EMERGENCY KEY & CALL The orange emergency key (or anyPF key) can be programmed to trigger an ANI option device.The emergency call feature switches the radio automatically to a pre-programmed channel for dispatcher alert.PASSWORD-PROTECTED PROGRAMMING AND CLONINGCloning enables duplicating of radios in the field via a simple interface cable without the use of a PC or special test jigs.For users who do not require cloning capability,a secure password can be programmed to prevent cloning of a lost or stolen portable.Additionally,all radios can have the programming password(s) protected to prevent unauthorized extraction and duplication.RADIO LOCK PASSWORD Preventing unauthorized use of lost or stolen portables,this feature requires an access code to be entered every time the radio is powered up (DTMF keypad models only).This password can be modified by the user in the field.EMBEDDED MESSAGE Deep inside the Flash memory of the radio,an electronic message can be stored containing owner identification,property I.D.numbers,user and department names,service records,etc..A radio can be electronically identified even if external labels,markings or factory serial numbers have been removed.PC PROGRAMMING AND TUNING To save both time and costs,radio parameter programming and tuning can be accomplished via the universal accessory connector from a PC-compatible computer without ever having to open the radio (KPG-35D software and KPG-36 cable options required).OTHER FEATURESPROGRAMMABLE TOGGLE SWITCH TALK AROUND BUSY CHANNEL LOCKOUT BCL OVERRIDE LOW BATTERY ALERT HIGH/LOW POWER MINIMUM VOLUME ANNUNCIATION TONE CONTROLCHANNEL SCAN FEATURES & DUAL PRIORITY Multiple or single group scan-ning,channel & group add/delete,revert channel,two priority channels are some of the parameters that can be set to accommodate any channel scanning need.Talk-back scan allows users to respond immediately to calls regardless of the pre-programmed or selected scan revert channel.Undesired channels can be deleted temporarily with the nuisance delete feature.FIVE PROGRAMMABLE FUNCTION KEYS (PF KEYS) Each key is programma-ble for virtually any radio feature and this allows the unit to be customized to fit user needs.Additionally,a selected PF key can be programmed as a “shift”function which allows all other PF keys to have a second function or a “secure”two-step activation (e.g.scan delete/add).DTMF SIGNALING & DIALING FEATURES DTMF PTT ID provides a built-in ANI forbusiness and industrial applications (both keypad and non-keypad models).For DTMF keypad models,manual DTMF provides system access and remote control functionality.Also included are dialing features for telephone interconnect and/or PBX access.OPERATOR SELECTABLE TONE/CODE (OST) Designed specifically for forestry,wildlife management and cooperative fire departments,the OST feature provides a programmable bank of 16 user-selectable tones (QT & DQT) for accessing differentrepeaters.Each tone can have an assigned alpha-tag and be directly accessed by keypad or other radio controls.BUILT-IN SELECTIVE CALLING (TWO-TONE & DTMF) Two-tone decode allowsfor three code pairs,each with individual and group paging settings.The DTMF selective calling provides individual call,group call,and over-the-air disable/enable.Both signaling types are assignable on a per channel basis and have audio-visual call alerting.FLASH MEMORY ADVANTAGE To facilitate the planning of impending system architectural changes and custom needs,these portables have main and reserve Flash memory caches to accommodate future updates and advanced feature sets.I NTUITIVE USER INTERFACESEVEN CHARACTER ALPHANUMERICS &ICONS The top display provides seven characteralphanumeric channel name-tags,a group number and noncryptic easy-to-read operational icons.Special operational modes are also displayed during setting mode for positive visual feedback to the user.These features help to facilitate fast radio user training and ensure continued user-friendly operation.Nighttime viewing is also enhanced by the lighted displaycapability with programmable manual,automatic timed shutoff and disable features.INVERT ALPHA-DISPLAY Any one of theprogrammable PF keys or toggle switch can be set to invert the channel alpha-tags for ease of viewing when the unit is worn on a belt,inside a protective suit or on a chest-pack.PROGRAMMABLE TWO-COLOR LED The two-color LED provides traditional transmit/ warn-ing (red),receive (green),and alert (orange) visualindications.This LED is recessed to limit omni-directionalvisibility to everyone except the radio operator.If desired,the “green-busy”and “red-transmit”activities can be disabled independently for law enforcement or covert work.StandardMIL 810CMethods/ProceduresMIL 810DMethods/ProceduresMIL 810EMethods/ProceduresLow Pressure500.1/Procedure I 500.2/Procedure I, II500.3/Procedure I, IIHigh

Disable: Decode signaling is disabled during off hook.Setting this parameter to Enable allows the radio to operate in decode without having to wire the off-hook signal to the on-hook position.XXI. Set the Access logic sig parameter to Sngl. Pulse. This logic signal is useful for external radio control unit (i.e. Mobile Data Terminal, Computer Aided Dispatch or Over The Air Re-Programming etc) that require a signal at the time of successful trunked repeater access. Options include:A. Continuous: Logic Level high during length of access.B. Sng. Pulse: Logic level high pulse at the time of a successful handshake.XXII. Set the Horn alt logic sig parameter to Pulse. The Horn Alert logic can be used to drive a vehicle horn relay, light or other device. The logic level signal can be set for a continuous (EX: light) or momentary pulse output (EX: vehicle horn relay). Options include:A. Continuous: Continuous logic level low output until reset.B. Pulse: Momentary logic level low output.XXIII.The options should now appear as:XXIV. Layout all of the repeater input frequencies in the first group. Setup each repeater output frequency in a separate system. Using the Kenwood3.exe program, the hexadecimal representation of each frequency can be determined (as seen in the table below).Group & System ConfigurationGroup 1Group 2Group 3Group 4Group 5Group 6Group 7Group 81KC7MCCTX A927.2125CarrierCH. 170xD197KC7MCCTX A927.2125EncodeCH. 170xD197KC7MCCRX A902.2125CarrierCH. 170x0190KC7MCCRX A902.2125EncodeCH. 170x0190KC7MCCTX B927.2250CarrierCH. 180xD297KC7MCCTX B927.2250EncodeCH. 180xD297KC7MCCRX B902.2250CarrierCH. 180x0290KC7MCCRX B902.2250EncodeCH. 180x0290The carrier access groups are not intended for active use but support test configurations, such as performing a -12 dB SINAD measurement on a receiver.XXV. Set the system configuration to Conventional.XXVI. Hit Enter to edit the system configuration.XXVII. Program each group as follows:A. Set the FCC field to 200.B. Set the transmit Encode field as appropriate.C. Set the receive Decode field as appropriate.D. Set the Grp-Name field as appropriate. Use unique text that will help you identify the group name whenusing the HxD program at a later step.E. Set the TlkArnd field to Yes.F. Leave all other fields at their default values.XXVIII. Save the KPG25D configuration file.XXIX. Exit the KPG25D.exe program.XXX. The KPG25D.exe program will have inserted a value of 0x089B, corresponding to channel 200 or 937.5000 MHz, into each of the frequency slots. The channel numbers are stored as a 16-bit word in little endian format. Endian swapping the default channel value results in a value of 0x9B08, which converts to a decimal value of 39688. The decimal channel value can be determined by subtracting the target frequency from 937.5000 MHz and then dividing by the channel frequency step size of 0.0125 MHz. The resulting value is then subtracted from a value of 38923, converted back to hexadecimal and then endian swapped into little endian format before storing the frequency. This is apparently what the Kenwood3.exe program does (except that the conversion to decimal and endian swapping is not required in programming since little endian is the native format for x86 processors).XXXI. Launch the HxD.exe program.XXXII. Open the KPG25D data file with the HxD program.XXXIII. Locate each frequency entry with a value of 0x089B and edit the value to the appropriate value obtained from the Kenwood3.exe program. The Grp-Name field data will be visible in the window and will help to locate the 0x089B value associated with a specific group name..XXXIV. Save the file and exit the Kenwood3.exe program.XXXV. Launch the KPG25D.exe program.XXXVI. Load the KPG25D data file.XXXVII. A view of the Feature option window will show the new channel data.XXXVIII. Program the radio.Filter InstallationTwo TK-941 radios are used to implement the full-duplex link back-bone, with one radio acting as the transmitter and the other radio acting as the receiver. The front-end filter on the receive radio must be swapped out with a filter that has the bandpass frequency having the receive frequency fall within the bandpass.A hot air SMD station was used to remove the pair of filters from the TK-941 receive radio front-end. 915 MHz filters were then installed using a standard soldering station. Note that the filter terminals did not align with the solder pads on the printed circuit board. The terminals had to be bent in to contact the pads prior to soldering. A check was made, using an Ohm meter, to verify that the terminals did not short to the ground traces surrounding the filter terminal pads.Upon completion of the filter installation, the VCO was adjusted to obtain VCO lock.Repeater Controller Interface - Receive RadioThe repeater controller interface requires access to the COS signal and de-emphasized audio. The signal driving the BASE of Q20 presents an Active LOW COS. Further, the COS signal carries only the COS when programmed for COS access or the logical NAND of COS and Tone Decode when programmed for tone or DCS access. The observed logic level on the COS signal shows 3.6 volts when HIGH.Squelch gated de-emphasized audio is available at the junction of C75 and IC6-13. The signal level of the audio, using a 1KHz tone with 3KHz deviation (as used for a -12 dB SINAD measurement), was observed to be 1.2 Vpp.The following annotated PCB view shows where to connect the COS and Gated Audio signals to interface to the repeater controller.The following image shows the repeater controller interface wires attached to the receive radio. The COS wire is blue. The squelch gated de-emphasized audio is orange. A black ground connection is made at emitter of Q20. A Dremel tool was used to grind a small slot to route the cable out of the RF shielded area where the interface signals are available. A Hot Glue gun was used to fasten down the wires, providing strain relief for the PCB pad connections.The power cable chassis strain relief can be lifted, exposing a small but removable plug. Removing this plug allows for routing of the repeater controller interface wires out of the radio chassis.Repeater Controller Interface - Transmit RadioThe transmit radio requires access to the PTT and Microphone input signals. The front panel was removed in preparation to route wires from under the power cable and on to through the chassis to the front panel PCB.The attachment points on the back of the front panel PCB are well marked as follows:1. PTT: Push-to-talk (Green Wire)2. ME: Microphone Return (audio-signal-ground - Black Wire)3. MI: Microphone Input (Red Wire)。
