John, Regarding the hum - it's just trying to remember the words... ;-)
Seriously, it sounds as if you suspect CTCSS coming through, and I would agree. First you need to know is whether this happens ALL the time or not. If it occurs all the time, it sounds as if your repeater's CTCSS tone encoder is at fault; if it occurs only occasionally, then someone else may be over-deviating their tone. Happy hunting... 73 de Mark - N9WYS -----Original Message----- From: Repeater-Builder@yahoogroups.com On Behalf Of W3ML Hello, I wanted to thank everyone again for the recommendations on how to fix our system. I made several of the changes posted and we replaced the antenna and hardline with new ones. The system is working right now. The problem with the radio power going up has stopped and the noise is all gone when people talk. Only one thing to figure out is a low hum coming across on transmit. We have ruled out the power supply. From what I have read on here today in old messages, I feel it may be the CTCSS coming through. But, it is nice to have the power up high and to be able to understand people when they talk instead trying to make it out through the noise. Thanks again for all the help. 73 John, W3ML
