• 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.

GP320 - Error tone on transmit after CPS programming

Hi All,

Wonder if you can help me with this. I posted the question on another board but no-one was able to answer.

1. I programmed a radio to my freq and it worked fine
2. I started messing around with SELECT5 settings and setting up selective calling, and it seems that this caused the radio to fail to transmitt for 1 second and then give a constant error tone.

See the video here on what it does now:
YouTube - Motorola GP320 - Error tone on TX - Suggestions?

3. I reverted back to a saved backup codeplug - no luck!
4. I reverted to the default GP320 VHF codeplug - it transmitts and then the radio seems to turn off.

This must be a software issue, right? Do you reckon flashing the firmware will clear the codeplug, and I can put a completely clean one on?

Cheers guys
