[amsat-bb] fail safe

[Bob W7LRD <w7lrd@xxxxxxxx>]

Hello	
In "resetting"up my station for mode "B" & "A", as well as "S"band
receive  (Drake).
I realized that if I'm not careful, I could easily apply RF to the output
of pre amps and or converters.  I would be curious to know what kind of 
"fail safe" measures some of us use to prevent such catastrophes.
