Thanks for your thoughts, John. I have not pursued intermod as a potential cause of this problem because there is not any other audio present on the signal head 30KHz away from our carrier frequency, and the offending signal is always present when our system is keyed up. There are not isolators on either transmitter. I did not mention that the two sites are also about 20 miles apart. Thanks again,
