I recently purchased a Motorola CDR700 UHF Desktop Repeater, complete setup, duplexer and all, the seller and I agreed it would be a fully functioning non-DOA purchase, so I don't intend on returning it unless the issue I have cannot be fixed easily
The first issue I ran into was no audio coming out the transmit side. You could key up and talk all you want but nothing would come out except dead carrier, so I returned the repeater to original programming although that didn't work, next I played around with some settings and figured out one of the options was set wrong, that was fixed. Easy.
Next problem, the repeater literally goes like 50 yards down the road then dies. My first thought and I've dealt with this before is perhaps the PA blew. So, I switched out the controller cables from each radio as well as the cables to the duplexer. Did a test, still goes the same distance, I think it's very unlikely the PA is blown on both radios, so that leads me to the next idea.. Well, I don't have an idea on what would be next. Has anyone had this issue before and can lead me in the right direction?
Some more info that may be helpful: I am using 75 foot of brand new LMR400, output power is 20 watts, duplexer is properly tuned, antenna is a 1/4 wave mag mount.
Thanks in advance, 73s.
