Like Pete, I am (was) very familiar with that ridge ... with all
of the stations converted to digital the only possible issue will
be channel 13 but it's not likely to effect anything on HF, six
or two meters. Channel 13's relatively high peak power in digital
operation may effect 222-225 MHz operation and you may need a good
front end filter if you care about that band. However, if you're
right on the ridge on in the valleys on either side, you may even
not even get enough signal to receive the stations well because
their signals are directed to the horizon and "down" toward the
bigger cities.
One of the better places for station technical data is through
the links from http://www.fcc.gov/mb/engineering/maps/. Put
the pin on your QTH and you can get technical data for every
station in your community from the FCC database.
