Skipp,
We have new commercially made RG-400 cables on both the transmit and receive side, and we have RG-214 from the tee to the Heliax transmission line. The new cables could have a fault, of course. I am going to take a break from this - going to the beach. I'll get back to it after that, and I'll let you know what happens. Thanks for all the help.

I get about 12 to 14 dB of desense. Is that possible? May not all be desense but what the overall effect you experience is lumped in together in the same "desense" label. > I believe that re-tuning the duplexer is the next step.

Few if any cables regardless of type are "100% sin free" including hard-line. Ensure you have as much practical physical cable spacing as possible. It doesn't take much stray RF energy to really rain on your receiver parade. s. __________ NOD32 3192 (20080616) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com
