• 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 am looking at purchasing a CDM1250. The model number is AAM25SKD9PW2AN. According to the model chart on Repeater-Builder.com, the PW indicates that the protocol is 1.5ppm stability UHF only. What does this mean exactly? I only need to program conventional analog frequencies, but want to make sure this will not prevent that. All of the other CDMs I have are AA (conventional) for the protocol part of the model number.

Stability is a measure of allowable frequency drift, or the difference in frequency between what the radio is programmed to and what is actually transmitted.

The 1.5 ppm (parts per million) stability is an upgrade to the standard 2.5 ppm stability specified for the standard (AA) CDM1250 version. You won't notice any difference in programming or capabilities with the PW version compared to the standard version.

FCC rules (90.213) for UHF radios specify a maximum of 2.5 ppm drift allowed for mobile radios. If a mobile radio is used as a base or control station then the maximum drift allowed is tightened to only 1.5 ppm. This is the reason Motorola offers this higher performance model, to comply with FCC rules when using a CDM in a...

Thank you for the clarification! That is exactly what I needed.
