      A drawing from 1964 in an AT&T Long Lines project file mentions three bays
      of ERCO model 361-TB transmitters at the Lewistown, MD microwave station,
      with frequencies of 243, 288, and 293 MC. Could that be the Wheelhouse or
      Minuteman system?

      BSP 406-100-100 (on microfiche) describes the 361-TB as a 100-watt
      crystal-controlled AM transmitter operating in the 225-400 MC band. The
      transmitter mounts in a free-standing rack cabinet, which includes space for
      the companion model 362-R receiver.

      Project file reference: Randallstown, MD folder titled "EA-31579 / 8-02921 /
      OF 047
      (LEWISTOWN)"

        243 is "Guard" - the UHF equal of 121.5, the international distress
        freq.

          I think MinuteMan & Wheelhouse were VHF land mobile;this is military
          a/c band & probably used for comms with choppers & other a/c passing
          through the area to Site R,etc.

          Lewistown would be a good location for that type of communications - it s about 12 miles from Site R, 5 miles from Camp David, less than 30 miles from the

            Lewistown would be a good location for that type of communications - it's
            about 12 miles from Site R, 5 miles from Camp David, less than 30 miles from
            the Hagerstown 2 and Leesburg "Project Offices", and about 42 miles from
            Mount Weather.
            It's at one of the higher elevations in the vicinity (1840 ft.), and I think
            it's the tallest AT&T tower in the DC area, at 406 ft.
