WTB: ARC-5 Recv & Xmtr Modulator

[Wilson Lamb]

Great story!
I ran a KW on 15MHz as a kid (1957), but never had the nerve to put out an 
address for SWL trolling.  Radio Moscow was bragging about how many tractors 
the ussr was building, so it seemed good to counter with some good big band 
swing music.  I thought it was pretty good to make the Garrard turntable and 
mag pickup work right next to that unshielded pair of w-400s!  The antenna 
was a dipole above our house, with enough field to light the stairway light 
full brilliance when the frequency was just right.  I expect I irradiated 
the whole family above recommended levels.  My old Collins 310-B (still use 
it) has quite wide coverage! Hopefully there's a statute of limitations on 
this stuff.
