Jim, This is the problem I've experienced, and why I think my receiver is "noisy." I can hear a high frequency whine or tone that only gets worse if I adjust the receive EQ to enhance voice intelligibility. This can make working weak signals fatiguing. I should probably just cough up the money and swap out DSP boards for a new one with an LPF installed. However, I'm not too thrilled about the unannounced price increase from 69 to 89 dollars. Had I known, I would have ordered one earlier.
