2010年9月2日 · I have a Motorola 42-50mhz split CDM1250 that I would like to put on 6m. I have the appropriate software for the radio and all the equipment, but of course the CPS wont let me go above 50mhz without making it an invalid field.

2021年5月16日 · We have been trying to set up some CDM 750 radios to create a split site 6m repeater. Receiver operation is great. They tune to 52.87 fine with expected sensitivity. We are using RTCMs and Allstar voting to create the repeater which lets us have multiple receivers and steer the transmit feed to a different radio if there is a failure.

The 6m repeater works fine, as long as you're standing next to it. The transmitter isn't putting out - or should I say, can't be heard, and the UHF link can't hear the other end. The first test pretty much tells us that there either isn't an antenna at the end of the feedline, or it's a dead short.

2022年2月27日 · The CDM is available in a high and low power version for VHF and UHF. The nice thing about the low power units is they can go from 1-25w and while the high power are 20-45w. As sometimes the link radios are best run at low power or if building a repeater it's much better to run a low power radio at 15W into an external PA then a high power ...

2017年8月25日 · With a 6m CDM, +4 MHz was added to all the tuning the points. So what should I do with a 10m CDM which I only need to program 200 - 300KHz out of band? Is a smaller change (ie -300KHz) preferred over a bigger (say -2Mhz) change...especially since the 29.7 MHz CDM are designed to only work over a very small frequency range ie 29.7 - 36 MHz....ie ...
