Donations of information, especially PDFs of manuals that we don't have would be greatly appreciated.
Your author / page maintainer has little personal knowledge of Kenwood
radios beyond what he had to research as part of a project or projects.
Comments, corrections, critiques, suggestions and updates for this page (or any page) are appreciated.

If you have a hint, or a useful trick, please consider wiring it up, writing it up and sending it in.

Kenwood seems to use the following convention for radio model numbers:
TK- for Commercial (two-way) Land Mobile Radios (LMR),
TKB- for Commercial LMR Base Stations,
TKR- for Commercial LMR Repeaters,
NX- for Commercial LMR digital portable and mobile radios ("NextEdge" is their digital protocol),
NXR- for Commercial LMR digital Repeaters,
TH- for Amateur Hand-held (portable) radios,
TM- for Amateur Mobile radios,
TS- for Amateur Station radios.

TK / TKB / TKR-6xx and 6xxx seem to be low band,
TK / TKB / TKR-7xx and 7xxx seem to be VHF-highband,
TK / TKB / TKR-8xx and 8xxx seem to be UHF.
TKR and NXR for their LMR / commercial repeaters.

Kenwood 900 MHz Information has been moved to a separate page.

Kenwood TKR Repeater Information has been moved to a separate page.

Don't forget ‑ Whenever you acquire a new-to-you synthesized commercial radio (any brand, any type, portable, mobile, repeater, anything) remember to download and save the code plug that it came with (with the frequencies that were in it) and archive it. And I'd save your tuning data as well. If you screw up later on then having those original file(s) allows you to backstep and restore the radio back to where you started and you can try again. Just save the code plug and the tuning data on your hard drive and use the radio serial number as the file name (example: kw_tk-840_90500789.dat_original) It's much better to waste a few kilobytes of hard drive space on a backup you may never need than to need a backup you don't have and can't get.

General Information

A Programming Cable note: Kenwood uses a variety of programming cables for their commercial radios.
Note that Kenwood numbers the 8-pin mobile radio microphone jack pins backward from Ethernet.
The 6-pin ones may number them backwards from telco numbering.

Most of the older mobile radios use a KPG-4 (click for photo) programming cable - it has a 6-pin modular connector (RJ-11 / RJ-12 / RJ14 style) on the radio end (it plugs into the microphone jack). The original KPG-4 cable had a DB-25 on the computer end, the modern cable has a 9-pin "D" female connector to match the computer COM port. The older radios that use the KPG-4 tend to use MS-DOS radio programming software and you need a programming computer with a real serial port (a DB9 male connector). Some of the older radios have had the software updated (Kenwood has isued a newer version) with Windows compatibility (examples: KPG-49 v4.21 for the TK-280-380-480-481-780-880-980-981 and KPG-56 v4.22 for TK260G-TK-270G-TK-760G-TK868G are two of them).

The KPG-46 is used on the newer mobile radios - it has a 8-pin RJ-45 (Ethernet style) modular connector on the radio end. The original KPG-46 cable had a DB-25 on the computer end, the modern cable has a 9-pin "D" female connector to match the computer COM port. A number of aftermarket suppliers produce a USB version. photo of both KPG-46 cables

The KPG-22 (click for photo) is used on some handhelds, it has a dual connector (1/8" mini and a 1/16" sub-mini connectors) photo of a dual KPG-22 and KPG-4.
The most common version of the KPG-22 is the USB version.
The real Kenwood KPG-22 cable has a DB-25 female connector on the computer end.
The predecessor to the KPG-22 is the the KPG-8, which requires an external DC power source where the KPG-22 is powered from the computer COM port. Anyplace you see that a KPG-8 is required you can substitute KPG-22. (anybody have a photo of a real KPG-8 or a real KPG-22 ?)
Note: A number of chinese manufacturers (like Baofeng and Woxun) use the KPG-22 cable.

The KPG-36 (click for photo) is used on some handhelds, it has a one-piece speaker/microphone connector.

If you are very careful with the KPG-4 cable (6-pin radio end) you can use it to program a radio that normally would use a KPG-46 (8-pin radio end) cable. The active pins are in the correct position and if you carefully center the 6-pin plug into the 8-pin connector on the radio (using the click tab) it will work - most of the time. But don't count on it, especially if the tab breaks off in the field (and it will).

Your page maintainer finally resolved the homebrew cable and KPG-4 versus KPG-46 issue by purchasing one each KPG-4 (9-pin female "D" connector) and one of the USB FTDI KPG-46 cables from Mark Dunkle at www.bluemax49ers.com. (Off-site pointer - opens in a new browser tab)
Mark's FTDI based USB cables DO NOT need any funny drivers and they just plain work. You can buy through his web page and avoid the eBay or Amazon markup. No, he's NOT paying me for providing this pointer.

You can build your own KPG-46 cable! by By Ephraim Gariguez DW1ZWS Off-site pointer, opens in a new browser tab.

Another Programming Cable note: Thanks to Chris WB5ITT for this tidbit…
Some Kenwood radios (the TK-780 and TK-880 are two) have a "gotcha"… the radio should be powered OFF when plugging in or unplugging the programming cable. The reason is that +8 volts DC is provided to the programming cable circuitry through a surface-mount resistor in the radio (pin 1 on the microphone jack). If that pin is accidentally shorted to ground the resistor is blown open and the programmer won't talk to the radio. The microphone will still work normally since it doesn't use that power… but the programming cable does.
Your page maintainer (Mike WA6ILQ) has seen that… Locally several TK-880s have been found for sale cheap as the radio won't program. Using a KPG-8 cable instead of a KPG-22 cable works, or you can replace the SMD resistor so that a readily available KPG-22 cable works…

Another Programming Suggestion: Newer Kenwood radios have a digital mode called NXDN. Other manufacturers have DMR. Then there is P25. Common wattmeters CAN'T read any digital transmissions accurately. If you are running a NXDN or DMR repeater always program a conventional channel even if you are running digital as the normal mode… this allows quick and easy power tests.

One more radio programming thought…
If you do a lot of radio programming, especially at repeater sites, you might want to consider dedicating a laptop to radio programming. My thoughts on dedicated radio programming laptops are here. (opens in a new window)

Kenwood Land Mobile Radio (commercial) Products by Mike Morris WA6ILQ
A little background information and some model-specific information, and some contributions from others. Updates appreciated!

From an email:
The following TK mobiles will all go down to 440 MHz: TK-805D TK-830 - see note below TK-840 TK-860 TK-860G TK-880 TK-8160 …as well as the following TKR repeaters: TKR-820 TKR-840 - see note below TKR-850 TKR-851 The TKR-840 does require a bit of a hack to get it down there, as the KPG-47D software won't let you enter anything below 450 MHz.
KPG-47D also programs the TKR-830, so it's likely that the same code plug hack works on that model too.
See this thread for info & the hex editing tool you'll probably need: https://forums.radioreference.com/threads/kenwood-tkr-840-uhf-repeater-need-help-programing-for-ham-frequencies.271724
Again this is for the TKR-840 but it MAY also work for the TKR-830.
The comment thread says that patching the KPG was attemped but didn't work. If a working patch is developed please let the page maintainer know. He'll add it here.

Note: Any KPG software with a "DN" suffix (i.e. KPG-91DN) will not allow programming wideband mode in a dual-mode radio. Unlike most Motorola software you can revert to a previous version (without the "N" suffix) and enable selection of wideband or narrowband.

Some notes on the "Packet connector" on the Kenwood TM-G707 and similar amateur radios by Mike Morris WA6ILQ

The PG-4S programming cable is used to program several models that programs through the front panel "packet" connector, including the TM-V7A and the TM-G707A. You can make your own using info from the KA7O web site page on the PG-4S. (update: That link takes you to the Wayback machine saved page from November 6, 2017) Supposedly you can use an inexpensive KPG-4 (6 pin) or KPG-46 (8 pin) cable from eBay and cut off the radio end and use a 6-pin mini-DIN plug, or use the cable and plug from a dead PS/2 mouse), or make an adapter from a 6-pin or 8-pin jack and the plug end of a PS/2 style PC keyboard or PS/2 mouse extension cord.

Homebrew programming interface equivalent to the KPG-4 35 kB PDF from K9MN
The KPG-4 is the RS-232 to TTL cable that is used for programming most any commercial Kenwood radio that has a 6-pin (RJ-12) microphone jack. The KPG-46 is the 8-pin (RJ-45) version.

Another version of the above KPG-4 replacement by Craig Clark N5XNQ, forwarded by KC7GF
This diagram is similar to the above but with a lot more info - it shows the DE-9 and DB-25 connections, and the handheld connections. It shows the 6-pin microphone plug.

A programming interface similar to the above KPG-4 units
This one corrects a few omissions in the above diagrams. Best of all, it actually works.

Kenwood has a software download page for some of their amateur products here.

Replacement 2-Pin Radio Power Connectors
Ths connector is used on both mobiles, and on repeaters (like the TKR-x50s and NXR-x10s). Your page maintainer had to replace the power connectors on a number of Kenwood mobiles… TK-840s, TK-8160s, TK-8180s and more. A friend had already researched the original connector and was happy to share his information.

Field programming the TK-270 or TK-370 Handhelds
A writeup on front panel programming of these models. It's somewhat cryptic and since I don't have one of the radios to experiment with, I can't build on it. If anyone wants to add some detail (or some photos) feel free to, then email it to me (the page maintainer listed above).

Kenwood Alternate Programming Procedure by Don Bindner
He had troubles reading/writing his TK-730 radio directly, so here's an alternative method to get them programmed.

A tip on the UHF TK-805 radio: BEFORE YOU BUY AN 805(D) CHECK THE VERSION NUMBER ON THE BACK. There are four different versions of the 805 and 805D and you need to look at the rear FCC ID# label. An FCC ID number ending with "-1" is for the 450-470 MHz band. A "-2" is for the 470-490 MHz band, a "-3" is for the 490-512 MHz band and a "-4" is for 406 to 430 MHz "government" band. The 450-470 MHz band TK-805D will work fine with no modifications in the ham bands, however you will need the "H" version to get 45 watts out of them. The stock non-H versions only put out around 30 watts.

Manuals and Brochures

The Kenwood publications group seems to have decided that a "dual band" radio is one that is capable of operating on two bands simultaneously
while a "twin band" or "two band" radio operates on only one band at a time.

Dan N2AYM reports "I have repaired quite a few Kenwood TM-331 radios, replacing the memory batteries and RF Amp modules. The TM-231 / 331 / 241 / 441 / 541 models are of the same basic configuration inside and if you review the service manuals it is evident they are almost the same with the possible exception of the spectrum covered. They all use the same Lithium Memory backup battery. This part number has changed so the service manuals will have the old part number (W09-0326-05); the new number is W09-0599-05. When I called East Coast Transistor Parts their price was only $6.00 each which seems very reasonable. This battery is a CR2032s with solder tabs for installation in the control heads. When I replaced the RF Amp module (M57774), I found that there had never been any thermal compound between the amp mount and the heat sink, which may have been a production error and may have contributed to the amp's problem with excessive heat over a period of time. I naturally used thermal compound with the new one."

Some notes from Mike WA6ILQ on the TM-641 / 741 / 941 / 642 / 742 / 942 radios:
1) If you need CTCSS/PL decode you will need to plug in a TSU-7 board. The firmware already "knows" about it.

2) The remote mount kit is a DFK-3, DFK-4 or DFK-7 (3 meters, 4 meters or 9 meter long cable).

3) A replacement microphone is a MC-45 (plain) or MC-45DM (with 16-button DTMF).

4) The TM-641 / 741 / 941 / 642 / 742 / 942 radios can draw as much as 12 amps on transmit, and the DC wire pigtail hanging from the back of the radio and the matching power cord that was shipped with it was, in my opinion, undersized in AWG. The transmitter is sensitive to low DC voltage, a voltage drop of less than a volt can cost you 25% of the transmit output power. Start by measuring the voltage at the radio while transmitting ‑ the simple way is to temporarily push a couple of sewing pins through the insulation of the power cable right by the strain relief at the back of the radio, then clip your VOM to the sewing pins). While you are keydown compare the voltage at battery to the voltage at the radio. If the voltage drop is excessive while transmitting then you need to change the wiring to a larger AWG size (lower resistance) wire. Been there twice, done that twice, got the t-shirt (but not the coffee cup). I had close to a volt of loss between the battery and the the back of the radio. I replaced the short pigtail built into the back of the radio with the heaviest red / black zip cord I could find and changed to Anderson Power Poles instead of the stock "T" connector. At the time the biggest red / black zip cord available to me was 12 gauge, but since then I've seen 10 gauge on a spool at the local HRO store. Be careful, don't trust the outside diameter of the insulation to be indicative of the internal conductor size; look at the cross-section of the actual copper.

5) The TM-641 / 741 / 941 / 642 / 742 / 942 radios use a solder-tab-style CR2025 coin cell for memory backup. The coin cell seems to last forever if you keep 12v applied to the radio, or just a few years if it's in storage. If your radio needs a new battery I strongly suggest you replace the solder-tab coin cell with a socket. Here's an exploded drawing of how to get to it. There is barely enough space inside the radio for a coin cell socket - I had to file the edges of the plastic socket body down a little on each side to make it fit. The socket needs to be a vertical socket with top access (i.e. the cell is positioned at right angles to the circuit board). Here's a photo of the coin cell socket I used (thanks to Joe Orrico WB6HRO for the tip).

A "usability" note from Dan Hopper KU4NF on the TM-V7A radio and the PC software they provide to upload and download the 180 memories: if you download the radio's memory, move some locations around and thus create some newly empty locations, and then write it back to the radio, it doesn't seem to delete the now-empty locations like it should; it merges the upload with the memory contents resulting in duplicate locations where the old entries are visible in the empty channels in the new data. My workaround is to delete all the memories in the radio before doing a write to the radio, thus giving the new data a clean slate to program into. How do you erase only the memories and none of the other settings? None of the power-up hotkeys seem to do this. However, if you have the radio change the VHF/UHF channel ratio, it'll prompt you to OK erasing all the memories. Do that, then change it back to your original ratio or a new ratio, and then write from the software to the radio. Kludgy, but it works.

	A Programming Cable note: Kenwood uses a variety of programming cables for their commercial radios. Note that Kenwood numbers the 8-pin mobile radio microphone jack pins backward from Ethernet. The 6-pin ones may number them backwards from telco numbering. Most of the older mobile radios use a KPG-4 (click for photo) programming cable - it has a 6-pin modular connector (RJ-11 / RJ-12 / RJ14 style) on the radio end (it plugs into the microphone jack). The original KPG-4 cable had a DB-25 on the computer end, the modern cable has a 9-pin "D" female connector to match the computer COM port. The older radios that use the KPG-4 tend to use MS-DOS radio programming software and you need a programming computer with a real serial port (a DB9 male connector). Some of the older radios have had the software updated (Kenwood has isued a newer version) with Windows compatibility (examples: KPG-49 v4.21 for the TK-280-380-480-481-780-880-980-981 and KPG-56 v4.22 for TK260G-TK-270G-TK-760G-TK868G are two of them). The KPG-46 is used on the newer mobile radios - it has a 8-pin RJ-45 (Ethernet style) modular connector on the radio end. The original KPG-46 cable had a DB-25 on the computer end, the modern cable has a 9-pin "D" female connector to match the computer COM port. A number of aftermarket suppliers produce a USB version. photo of both KPG-46 cables The KPG-22 (click for photo) is used on some handhelds, it has a dual connector (1/8" mini and a 1/16" sub-mini connectors) photo of a dual KPG-22 and KPG-4. The most common version of the KPG-22 is the USB version. The real Kenwood KPG-22 cable has a DB-25 female connector on the computer end. The predecessor to the KPG-22 is the the KPG-8, which requires an external DC power source where the KPG-22 is powered from the computer COM port. Anyplace you see that a KPG-8 is required you can substitute KPG-22. (anybody have a photo of a real KPG-8 or a real KPG-22 ?) Note: A number of chinese manufacturers (like Baofeng and Woxun) use the KPG-22 cable. The KPG-36 (click for photo) is used on some handhelds, it has a one-piece speaker/microphone connector. If you are very careful with the KPG-4 cable (6-pin radio end) you can use it to program a radio that normally would use a KPG-46 (8-pin radio end) cable. The active pins are in the correct position and if you carefully center the 6-pin plug into the 8-pin connector on the radio (using the click tab) it will work - most of the time. But don't count on it, especially if the tab breaks off in the field (and it will). Your page maintainer finally resolved the homebrew cable and KPG-4 versus KPG-46 issue by purchasing one each KPG-4 (9-pin female "D" connector) and one of the USB FTDI KPG-46 cables from Mark Dunkle at www.bluemax49ers.com. (Off-site pointer - opens in a new browser tab) Mark's FTDI based USB cables DO NOT need any funny drivers and they just plain work. You can buy through his web page and avoid the eBay or Amazon markup. No, he's NOT paying me for providing this pointer.
	You can build your own KPG-46 cable! by By Ephraim Gariguez DW1ZWS Off-site pointer, opens in a new browser tab.
	Another Programming Cable note: Thanks to Chris WB5ITT for this tidbit… Some Kenwood radios (the TK-780 and TK-880 are two) have a "gotcha"… the radio should be powered OFF when plugging in or unplugging the programming cable. The reason is that +8 volts DC is provided to the programming cable circuitry through a surface-mount resistor in the radio (pin 1 on the microphone jack). If that pin is accidentally shorted to ground the resistor is blown open and the programmer won't talk to the radio. The microphone will still work normally since it doesn't use that power… but the programming cable does. Your page maintainer (Mike WA6ILQ) has seen that… Locally several TK-880s have been found for sale cheap as the radio won't program. Using a KPG-8 cable instead of a KPG-22 cable works, or you can replace the SMD resistor so that a readily available KPG-22 cable works…
	Another Programming Suggestion: Newer Kenwood radios have a digital mode called NXDN. Other manufacturers have DMR. Then there is P25. Common wattmeters CAN'T read any digital transmissions accurately. If you are running a NXDN or DMR repeater always program a conventional channel even if you are running digital as the normal mode… this allows quick and easy power tests.
	One more radio programming thought… If you do a lot of radio programming, especially at repeater sites, you might want to consider dedicating a laptop to radio programming. My thoughts on dedicated radio programming laptops are here. (opens in a new window)
	Kenwood Land Mobile Radio (commercial) Products by Mike Morris WA6ILQ A little background information and some model-specific information, and some contributions from others. Updates appreciated!
	From an email: The following TK mobiles will all go down to 440 MHz: TK-805D TK-830 - see note below TK-840 TK-860 TK-860G TK-880 TK-8160 …as well as the following TKR repeaters: TKR-820 TKR-840 - see note below TKR-850 TKR-851 The TKR-840 does require a bit of a hack to get it down there, as the KPG-47D software won't let you enter anything below 450 MHz. KPG-47D also programs the TKR-830, so it's likely that the same code plug hack works on that model too. See this thread for info & the hex editing tool you'll probably need: https://forums.radioreference.com/threads/kenwood-tkr-840-uhf-repeater-need-help-programing-for-ham-frequencies.271724 Again this is for the TKR-840 but it MAY also work for the TKR-830. The comment thread says that patching the KPG was attemped but didn't work. If a working patch is developed please let the page maintainer know. He'll add it here.
	Note: Any KPG software with a "DN" suffix (i.e. KPG-91DN) will not allow programming wideband mode in a dual-mode radio. Unlike most Motorola software you can revert to a previous version (without the "N" suffix) and enable selection of wideband or narrowband.

	Some notes on the "Packet connector" on the Kenwood TM-G707 and similar amateur radios by Mike Morris WA6ILQ
	The PG-4S programming cable is used to program several models that programs through the front panel "packet" connector, including the TM-V7A and the TM-G707A. You can make your own using info from the KA7O web site page on the PG-4S. (update: That link takes you to the Wayback machine saved page from November 6, 2017) Supposedly you can use an inexpensive KPG-4 (6 pin) or KPG-46 (8 pin) cable from eBay and cut off the radio end and use a 6-pin mini-DIN plug, or use the cable and plug from a dead PS/2 mouse), or make an adapter from a 6-pin or 8-pin jack and the plug end of a PS/2 style PC keyboard or PS/2 mouse extension cord.
	Homebrew programming interface equivalent to the KPG-4 35 kB PDF from K9MN The KPG-4 is the RS-232 to TTL cable that is used for programming most any commercial Kenwood radio that has a 6-pin (RJ-12) microphone jack. The KPG-46 is the 8-pin (RJ-45) version.
	Another version of the above KPG-4 replacement by Craig Clark N5XNQ, forwarded by KC7GF This diagram is similar to the above but with a lot more info - it shows the DE-9 and DB-25 connections, and the handheld connections. It shows the 6-pin microphone plug.

	Field programming the TK-270 or TK-370 Handhelds A writeup on front panel programming of these models. It's somewhat cryptic and since I don't have one of the radios to experiment with, I can't build on it.

	Kenwood Alternate Programming Procedure by Don Bindner He had troubles reading/writing his TK-730 radio directly, so here's an alternative method to get them programmed.
	A tip on the UHF TK-805 radio: BEFORE YOU BUY AN 805(D) CHECK THE VERSION NUMBER ON THE BACK. There are four different versions of the 805 and 805D and you need to look at the rear FCC ID# label. An FCC ID number ending with "-1" is for the 450-470 MHz band. A "-2" is for the 470-490 MHz band, a "-3" is for the 490-512 MHz band and a "-4" is for 406 to 430 MHz "government" band. The 450-470 MHz band TK-805D will work fine with no modifications in the ham bands, however you will need the "H" version to get 45 watts out of them. The stock non-H versions only put out around 30 watts.

	Dan N2AYM reports "I have repaired quite a few Kenwood TM-331 radios, replacing the memory batteries and RF Amp modules. The TM-231 / 331 / 241 / 441 / 541 models are of the same basic configuration inside and if you review the service manuals it is evident they are almost the same with the possible exception of the spectrum covered. They all use the same Lithium Memory backup battery. This part number has changed so the service manuals will have the old part number (W09-0326-05); the new number is W09-0599-05. When I called East Coast Transistor Parts their price was only $6.00 each which seems very reasonable. This battery is a CR2032s with solder tabs for installation in the control heads. When I replaced the RF Amp module (M57774), I found that there had never been any thermal compound between the amp mount and the heat sink, which may have been a production error and may have contributed to the amp's problem with excessive heat over a period of time. I naturally used thermal compound with the new one."

	Some notes from Mike WA6ILQ on the TM-641 / 741 / 941 / 642 / 742 / 942 radios: 1) If you need CTCSS/PL decode you will need to plug in a TSU-7 board. The firmware already "knows" about it. 2) The remote mount kit is a DFK-3, DFK-4 or DFK-7 (3 meters, 4 meters or 9 meter long cable). 3) A replacement microphone is a MC-45 (plain) or MC-45DM (with 16-button DTMF). 4) The TM-641 / 741 / 941 / 642 / 742 / 942 radios can draw as much as 12 amps on transmit, and the DC wire pigtail hanging from the back of the radio and the matching power cord that was shipped with it was, in my opinion, undersized in AWG. The transmitter is sensitive to low DC voltage, a voltage drop of less than a volt can cost you 25% of the transmit output power. Start by measuring the voltage at the radio while transmitting ‑ the simple way is to temporarily push a couple of sewing pins through the insulation of the power cable right by the strain relief at the back of the radio, then clip your VOM to the sewing pins). While you are keydown compare the voltage at battery to the voltage at the radio. If the voltage drop is excessive while transmitting then you need to change the wiring to a larger AWG size (lower resistance) wire. Been there twice, done that twice, got the t-shirt (but not the coffee cup). I had close to a volt of loss between the battery and the the back of the radio. I replaced the short pigtail built into the back of the radio with the heaviest red / black zip cord I could find and changed to Anderson Power Poles instead of the stock "T" connector. At the time the biggest red / black zip cord available to me was 12 gauge, but since then I've seen 10 gauge on a spool at the local HRO store. Be careful, don't trust the outside diameter of the insulation to be indicative of the internal conductor size; look at the cross-section of the actual copper. 5) The TM-641 / 741 / 941 / 642 / 742 / 942 radios use a solder-tab-style CR2025 coin cell for memory backup. The coin cell seems to last forever if you keep 12v applied to the radio, or just a few years if it's in storage. If your radio needs a new battery I strongly suggest you replace the solder-tab coin cell with a socket. Here's an exploded drawing of how to get to it. There is barely enough space inside the radio for a coin cell socket - I had to file the edges of the plastic socket body down a little on each side to make it fit. The socket needs to be a vertical socket with top access (i.e. the cell is positioned at right angles to the circuit board). Here's a photo of the coin cell socket I used (thanks to Joe Orrico WB6HRO for the tip).

	A "usability" note from Dan Hopper KU4NF on the TM-V7A radio and the PC software they provide to upload and download the 180 memories: if you download the radio's memory, move some locations around and thus create some newly empty locations, and then write it back to the radio, it doesn't seem to delete the now-empty locations like it should; it merges the upload with the memory contents resulting in duplicate locations where the old entries are visible in the empty channels in the new data. My workaround is to delete all the memories in the radio before doing a write to the radio, thus giving the new data a clean slate to program into. How do you erase only the memories and none of the other settings? None of the power-up hotkeys seem to do this. However, if you have the radio change the VHF/UHF channel ratio, it'll prompt you to OK erasing all the memories. Do that, then change it back to your original ratio or a new ratio, and then write from the software to the radio. Kludgy, but it works.
