Am I reading too much between the lines ?


Yes, tubes. I have some that were pulled from circa 1960's television
sets, and I thought I'd use them, hoping that they'd be EMP resistant.
Been on kind of a survivalist kick, lately. Doesn't mean I'd be opposed
to using more modern equipment, though. One thing I saw that I liked in
one of the books I purchased was a loop antenna that uses transistors
to amplify the signal. Thought it might be easier than stringing up a
lot of wire. ;-)


But the transistors almost certainly will be fried by EMP. If that's
not a concern, then by all means try it -- and share the design and
results with us, please!
