Our tx building has a framed up against the cement block wall divider wall
between the tx and the control room, puncture by several FCC mandated windows
since its not remote controlled, and this divider wall is lined with
galvanized sheet metal. How effective it might have been I have NDI. I'm
not sure why they felt it was needed as an antenna, microammeter & diode
carried around has to be very close to the non-screened windows in the
transmitter walls to get a full scale reading, and the renewal survey with
the Holaday leakage meter is absolutely zero except for one 6" square window
above the aural drivers 4-1000 stage. Even that meets the 1 hour exposure
guidelines.
All that was done BG (Before Gene) meaning sometime in the 1956 to 1984 time
frame. The place is a museum, in bad need of janitorial service since the
one operator I had that made sure it was cleaned up put himself and a Piper
Apache into a hill near Lake Floyd just east of Bridgeport about a decade ago
now. It was flying gear down dirty (hydraulic failure, headed for the shop in
Maryland to get it fixed) which means both engines had better be running
right or one should choose his crash site carefully. The NTSB says both were
running when it impacted. It also said the trim was fully nose down, and
that Apache wheel runs backwards to most small airplane trim wheels. He
could have gotten confused as he flew most anything they pointed to out on
the parking. A hired driver with a good reputation in fact.

It was initially driven by the local cable system & they were very carefull
not to exceed 1 millivolt into the house. It was a high vacuum suckage even
then, very noisy pix when 3 other tv's at the same splitter db were good to
go.
How'd we get so damned far off-topic anyway. :-)
