• 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.

M120 PA swap Question

I have a M33GMC20A2AA, that is going to be used as a APRS Digipeater. Right now it is not very happy working at 144.3900Mhz even after tuning the PA. Is it possible to just swap a PA from a low split PA? or would it just be better to look for a M33GMC20A1AA radio and sell/junk the hi split radio? After tuning the PA, at 146.000Mhz it puts out 25w but at 144.3900Mhz it is putting out less than 15w with the same current draw. Is it possible to retune the radio to be happy Transmitting 25w at 144.3900Mhz? After making a cable to interface with an OT3m i found it had a flaky 16pin connector, upon examining it i found some 'tech' had pooched to connector trying to jumper the speaker pins on the underside of the board. needless to say, the connector was removed and a pigtail for the Audio out/in, PTT, COR, and Ground to a DB-9 was installed to fix the hack job.
