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.

This seems specific to RPM. I bought a programming cable for the P5400, installed Prolific drivers.
Now I have had some bizzare results including starting RPM, connecting a P5400, turn on the power and the PC shuts down.
The most common fail is "serial port not supported in hardware". First error is "Port in use by another application" That cant be given RPM is the only app installed using serial ports.
This is on a Win 10 machine, and I have gone over every RS232/USB-RS232/and USB setting accessible.
Any one have a similar problem, did you cure it? , What was your fix?
One thing to note, this did work on a previous PC. so very puzzled.
