Ok all you helpful folks. I need some ideas. I have a UHF mastr II tuned to the ham band. I am using a NHRC-3/M2 controller. I have a 2 meter remote base on the 2nd port of the controller. I have both audio delay boards installed. I am running a TS-64 ctcss board in full encode/decode. My output is 25watts out of the cavities. I am using a set of TX/RX Varinotch cans. I am running a ARR preamp. The problem I have is this. Sometimes on the receive signal it sounds "crunchy". A signal will be full quieting and then it will get "crunchy" and then slowly clear up. On weaker signals the "crunchy sounding audio will just stay that way. I thought maybe this was caused by the AD but it was still there when i removed the delay board. This system was on 444.450/449.450 for abt 7 years with no problems. I moved and had to change the frequencies to 448.450/443.450. I also had a IFAS board fail a few months ago and swapped it out with one I had from another UHF Mastr II. Thoughts? ideas? places to start? Bring it on!! I need to make this thing work rght or take it off the air.
