• 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.

TK-790h Programming Cable KPG-43

I got this TK-790h and got it working after a few hiccups..
I know I should buy the cable to program the radio, but I'm cheap and I would love to know if someone can send me the pin-out diagram.
For what I've seen the 12pin Mic cable has only three connections.

I actually bought the USB version for this cable but it did not work. I have a good understanding on serial ports, so I think somehow the TK does not like this TTL usb connection

So the pin-out to RS-232 9 Pin would be great..

It has been a while but I seem to remember it not only being TTL conversion but also it carries data on one wire, so additional circuitry is required.

The issue is finding the 12 pin microphone connector…
Best thing to do is to buy an old microphone off e-bay and roll your own.

Pin 1 is at the 12 o'clock position, facing the end of the connector, the pin numbering goes around clockwise.

1 = Switched power
2 = Hook signal input
3 = Microphone Earth
4 = Microphone input
5 = Earth
6 = Transmit Data Output/Receive Data Input
7 = KVL
8 = Serial Data Input/Output for Keypad mic
9 = Mic Backlight control
10 = PTT
11= N/C
12 = Audio output for headset > 2Ω load.

KPG-43UM is the Kenwood USB programming cable.
