[SBE] WAGA Analog Sign Off w/ First CE - more on Analog shutdown.

[Barry Thomas]

Did not notice that it wasn't a TV site.  Good catch Alan.
I still love the 20E....Especially ones (the E1's) with the parasitic resistors in the PA so the thing doesn't melt down.

If you tweaked the 2 vacuum caps on the PA output that transmitter would be incredibly efficient (class C of course) and have pretty darn good AM noise.  


In the early '80s I moved that first 10E1 from the TV building to a new transmitter site and rebuilt it from the ground up.  It served as the backup transmitter for years after I left the market.  It was only 71% of the new TPO but I knew it would come on...no matter what.

The BTA-5T1.  Was that the one with that basically had a BTA1R as a driver stage?

If you happened to notice the site pictured (which was not a TV site), That site was the WPLO-590 5KW NDD/DAN /WVEE-103.3 100KW site when it was decommissioned around 1984-1985. I knew that site well having worked there for 3.5 years. Barry there were 2 (main and backup) RCA BTF-20E1's in that building for WVEE. The WPLO transmitters were a Gates BC-5E and a RCA BTA-5T1.
