[BC] Manual for Gates BC-1H morphing 2 ARM TX

[Robert Bowe]

Do you "pull the plug" to the ant when you sign-off?? or are you getting 
AC line hits?

We've got a couple of the X1000's here and one was having FET fails due 
to the phone (loop fed site) service having an independent ground.  
Needless to say I got real good at diagnosing FET fails and changing 
them out quick (there are a couple of undocumented tricks to do it).

That and we're using the IRFP264 for the modulator (the IXFH40N30 
doesn't have the spike protection of the IR).
I also designed a modification to the RF Amp Module so it'll actually 
turn off LED when the fuse fails (a design flaw in my book).

I have a fear of blowing mosfets in the Armstrong and right now, if we know there is a bad thunderstorm on the way, we instruct people to monitor the Nashville TV stations or monitor the LP-1 on FM for weather updates, then we sign off until the bad weather has ended. I don't want to take any chances on causing damage to the Armstrong, so the tube rig would be perfect for these events.
