![]() ![]() There's virtually no regular GMRS traffic in the area where I live except for a very few small businesses using bubble pack radios for in-store operations. Remember that the difference between 30 watts out and 50 watts out doesn't really give you 40% more range in most real situations. This means that you could set up a CDM for 5 watts on channels 1 to 7 and 30 watts for 15 through 22. They won't do the 0.5 watts required on channels 8 through 14. The low power (30 watt) versions of the CDMs can be knocked down to 5 watts channel by channel. No, the CDM family is not type-accepted for GMRS use. I also understand that some take the "If you don't get caught, why worry" attitude around questions like this, but - speaking only for myself, and no judgment here - "you do you," but I don't share that view. Some of the answers above suggest that it's totally fine, and if it is, awesome. Is the CDM1250 type-approved for use as a GMRS base station? Isn't the minimum power output too high? Right now it's programmed for several local Amateur repeaters in my area but I've got loads of Personalities free. I find this thread interesting, because whenever I've looked into getting my CDM1250 (UHF) into service on the GMRS spectrum, I've come away uncertain whether it's kosher/legal to do so. I suppose half the fun is figuring this stuff out. I've just ordered a quality pigtail cable to try to solve that. I've purchased two different min-uhf-to so-239 adapters and I am not satisfied with the way either of them fit/thread on. (that is the great thing about standards - everybody has one). The only other issue i am having is with the coax connector - the mini-uhf. Are there any good rules of thumb or common gotchas here someone could point me to? Is there just a stock GMRS codeplug someone can point me to or be might be willing to share that I can look at? There are alot of other features here I am not familiar with, and I suspect something is interfering (signaling tab maybe?). I'm pretty sure DPL/TPL codes are right - as I have the repeater working on a baby midland and a different HT. I'm having trouble programming the repeaters to work. I have all the channels programmed and all seems to be working. I've got the software and cabling all sorted out so I can program it. I've just gotten a hold of a used cdm1250. ![]()
