• 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.
  • Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Howdy,
Found some amazing info on here. I have a TK-790H Remote head unit in my Baja Bug. I'm trying to program it to use with an intercom. The radio transmits and receives with the mic that plugs into the head unit. I can also hear audio via intercom and transmitted from another radio through the headsets but when I push the PTT and talk through the mic on the headsets you can hear it key up on the other radio but when you talk no audio. I know it's simple what am I missing? Please and Thank you in advance.

I got one too! Works exactly the same. Got a couple of CPI terminals to connect it to as well.

When using the DB-25 connector there is a set of jumpers to swap inside the radio to enable mic audio from external accessories. I'll get you more info.

Hello ......... I have a bunch of these Radios. Great Radios. Built like a tank.
OK, your audio in on the back 25 pin connector should be on pin 13. Take the bottom cover off of the radio. You will see two jumpers marked 640 and 641. There is a zero ohm resistor on 641. Take that jumper loose. Put the jumper resistor or just solder jump 640 together. You should now have audio.

Mike
