Virginia Summits On The Air

After some Virginians volunteered to research the mountain peaks in the Commonwealth and see which ones are sufficiently prominent to qualify for the Summits on the Air (SOTA) program, we now, as of Feb 1, 2011 have 542 peaks from which to operate a ham station.

Virginia is now proudly represented in the W4 area.

Check out the Virginia peaks right here in this web domain.
