• 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.

I have been using a USB to Serial cable to program my Motorola Quantar repeaters. For some reason my computer won't recognize the driver for the programming cable. I originally purchased the cable on Ebay and it has worked great, but I have not been able to find a similar cable for sale. Does anyone have a suggestion of where I can buy a new cable.

Personally I use the Cables2go USB to Serial adapter cable. Cable works flawlessly with everything serial I have to deal with and that includes reprogramming Quantar repeaters

I've always had good luck with the IOGear GUC232A with everything except for Pro series CPS on Windows 7 64 bit and Windows 10 64 bit.

The cable for the Quantar is simply a NULL-MODEM cable and only requires TXD, RXD and Ground. Over the last few years I just used RJ45 to DB-9 adapters and manually pinned them out to give me a straight passthrough on the computer side and then pinned others out for Male NULL, Female NULL (because the Quantar uses a female DB-9 for the programming interface and the GTR8000 uses a male DB9). Then just hook a standard ethernet cable between and GTG. Also build one for the MTR2000.

Here lately I just have male and female ends and simply use a USB to Rollover cable (if you've worked with networking equipment you know what I'm talking about).
