[BC] AM Radio Kit

[Bob Barnswatts]

Sounds like the story of my life growing up on a farm.  I somehow got one of those breadboard kits you know where you can make a radio receiver, a little transmitter,  various other bells and whistles  and who knows what else out of it by simply reconfiguring the wiring.  (all powered by a 9 volt battery it was so powerful)  I had it out one day in front of the farmhouse and i had the old Ford F-150 radio on and the doors open and i was modulating something into it and listening to it on the radio and my mean uncle  at the time came flying out the door and raised hell that the FCC would be coming and we'd lose the farm and all be in jail and he tore it up right there and ruined my little transmitter.   So I never got to see how far it got out, that was the next step to take a ride down the country roads and check out my long wire antennae.  I was probably 13 at the time but still drove around the farm.  He ranted and raved so much and complained to my parents and eveyrone that would listen for weeks and i never heard the end of it that we were all going to go to jail if anyone ever found out what i had done on a saturday afternnon that summer so I, needless to say, never tried anything like that again (around there).  This was back in the early 70;s or late 60s.

-Bob.
