[Scan-DC] US Park PD?

For the 3rd time:


It is on South Mountain.  It's Reno Monument  Rd.  The ATC facility  likely has other uses.  Many years ago the NPS and the MD DNR repeaters  were on an old fire tower that was often vandalized and there was a  large telco microwave facility at the site as well.

The repeater  for the upper end of the canal used to be located on a hill in an apple  orchard near Paw Paw WV; it may now be on Cacapon Mt.  This repeater is  required to allow coverage west of Sideling Hill.  There was also remote  receiver for the lower end of the canal located atop the Defense  Mapping facility on MacArthur Blvd at the DC line.

At one time  USPP had a Ch. 3 repeater, which was linked to Ch. 2, at the WSSC plant  near Potomac, MD which allowed portable coverage on the canal in the  area of Great Falls and west.  Don't know if this still exists or not.

Lambs Knoll is located at the top of the hill that Reno Mountain road runs 
along in Washington County.

The Frederick County MSP repeater, some other repeaters, a "Air Traffic 
Control" facility, and some other stuff is up there.

I believe that the microwave for Manassas Battlefield and Prince William 
Forest, to download to C&O Canal is located up there now too.
