I tried posting something about this in the past but got no response. I'm holing that this time someone might read it who may have a theory as to what could be going on.

I live in southern New Hampshire and watch OTA TV out of Boston, which is about 60 miles from here. Lately I as well as several other people I know have been experiencing intermittent problems with channel four. While most other channels are presently operating fine, for the past 10 days or so channel 4's signal has been in the toilet. This station, WBZ TV operates on UHF channel 30, runs 825KW, and has an antenna height of 390 meters. By contrast Channel 5, WCVB, operates on UHF channel 20, runs 625 KW, and shares the same tower and has it's antenna at the same height as channel 4's, and we never have any problems with that channel. Could propagation be that much different 60 MHZ apart? What is really weird is that the signal just drops to almost nothing.

I discussed this with the chief engineer at Channel four and he had no explanation for this. Does anyone have any theories about this? Thanks, Lenny
