• 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.

CDM1250 not transmitting full output

Hi guys,
I have two lowband 42-50 CDM1250s. The code plug is cloned the only different being the PTT ID number.

The hi power limit is 67 watts and the low power limit is 35 watts.

When I hook one up to a bird watt meter it's only transmitting 15 watts on frequencies in th lower part of it's range (around 42-43Mhz) and on channels that are higher in frequency (around 46-48Mhz) it transmits about 25-30 watts.

All channels are set to high power.

When I switch the meter onto the other radio with the same list of frequencies the meter show a transmit power of about 65 watts on everything channel.

Does anybody have any input ast to what would cause this problem?
