[BC] Re: Oldest Transmitter still in daily service

[Milton R. Holladay Jr.]

There is/was a good RA-1000 aux at what was WFAG in Mullins, SC.
The RA-1000 audio circuit was identical to the BC-1F. The RF was superior in
that it had two 813 drivers rather than one, and was push-pull........
WKDK in Newberry has an RA-250 aux.
But the BC-1F at WAGS is the oldest thing I know of in daily use. Until May
2003, I had a 1958 317B in daily use.
