Thanks for the reply Jack. This 1501 is pretty new and was a great unit except for the FM issue. I have made FS measurements here at my house and the FM and TV energy was incredible. So my FM issue is unusual. I have moved your whip to a more remote location and it is great.
I have 8, 10, 13, 21, 31 HDTV channels and a handle of low power TV on the hill. WDKX, WCMF, WXXI, WPXY and others live < 1/2 mile away (Pinnacle Hill) too. So my location is atypical.
