[BC] Modualtion Monitors (do we need them?)

[Bailey, Scott]

Jerry,

I was thinking CC bought BE's at some of their 1 KW stations.  I know at
WHUB they installed a Gates 1 when I was helping them take out an old
RCA BTA-1R, they had no mod monitor there.  Just used a fluke scope to
check modulation. Clear Channel wanted all that old stuff out of there
and at that time, and would pay you to haul it off!
I tell ya Jerry, that old building was like going back in time. WHUB's
original box was there, an RCA BTA-250L. It was in the process of being
taken to somebody's house to be put on 75m.  I know the 1R is now on
160m.

None. All Harris transmitters (two SX-1's, one Gates 1, I think).
