[BC] Contractors doing stupid things. WAS P.O.ed

[Alan Alsobrook]

Imagine my surprise when I went in to a leased site and found one of my 
transmitters had been vented to the outside with ducting cut through the 
top of the transmitter and attached to the PA cavity. This was done 
while the transmitter was on, by a contractor at the request of the 
lessor (trying to cut down on the AC bill).

I don't know exactly what communications transpired between the lessor 
and the AC guys, but I do know he some how convinced them it was ok to 
cut open the top grating of the transmitter and put in the ducting. With 
them probably not knowing that they had their fingers within 2" of the 
B+ (5 KV) going to the back door interlock.

Needless to say the fecal matter hit the rotary blades.
