Hello. What programming cable does this radio use? I have a copy of KPG-21D, but am getting a communication error using a serial cable and DOS box. I use DOS box with many other Kenwood and Motorola DOS-based programs with no issues. I do have a real DOS machine I can try as well, but actually have less success with that than DOS box. Does it not use the standard microphone jack programming cable? If not, does anyone have photos, part numbers, or pin outs of the cable I should be using and where it plugs in? Thanks

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.
Programming a Kenwood TK-620

The oldest PC I have is a Pentium II. I hear this program is finicky with CPU speed. Could that be it? Although usually DOSbox works on RSS/CPS/FPU programs that require a low CPU speed.
You need a KPT-50 and that plugs into a connector on the inside of the radio. Or you can use a KPT-20 EEPROM programmer.

Oh, even if you have the software?
Yes, use the KPT-50 with the software.
Dang it. Okay. Thank you very much!
Probably. I did buy it on eBay with another radio. Why’s that?
I bought it like 10 days ago. Probably a different one. Came with a Maxtrac
is there even a programmer floating around ...? our kenwood dealer here back in the day threw 2 away......
Yes. However I paid about $30 for the radio, so I am not planning on spending $200+ on the programmer. I reached out to a former radio system admin and Kenwood LMR employee friend and he said he hasn’t even seen one of these radios in over 10 years let alone programmed one, just remembered you had to remove the case to program it. Likely I will be cutting my losses.
it is too bad no one in the area has a programmer that could program it for you sad to see a good radio like that get put on a shelf and forgotten. and ya the programmer on there i was not recommending due to what looked to be water damage just tat that do pop up and i have seen them as low as 50. if i was in your area i would help program as i do have a programmer

Is this the mobile TK620 and not the TKB-620? I believe the KPT50 is only for the TKB and TKR series of radios.
With that said, I removed 93C46. Eeprom and was able to change the freq data. It was on a UHF 820, but it's the same
on the 620.
From what I've seen in the file saved by KPG 21D prg that works with KPT50 and the actual Eeprom data, the data is the
same, it's just the 2 bytes are reversed. ie '1234' vs '3412'
I don't have a KTP50, but maybe you could read/write and then reverse the bytes, so the KPG21d program could then read
the data? I did write a simple program to reverse the bytes.
Some to consider. Pete

Thank you. That is some very useful info. It is the mobile, not the base. Perhaps I will get an EEPROM programmer.
