[BC] My AM Radio Kit Antenna...

[Dennis Cope]

I built mine, back in 66 using a 6L6 with the coils wound on a Quaker Oats
box, a variable cap and was driven with a 7 watt amp that used a 50C5.

The B+ for the 6L6 was fed from the 50C5 (I believe it was about 125 volts).
Of course the 50C5 was the modulator.  Fed a long wire about 75' and could
be received about 3/4 of a mile.  Like you said, "What's coupling?".  I was
16 and having fun...

Ok guys - It was the early 50's and I was about 13 at the time.  Mine
was a thing called and Electronic Baby Sitter.  It also had a 50C5
modulated by a 50C5.  Sort of a MOPA, like a tiny BC-375.  This thing
was on 550 KC.  My antenna was a 750 foot longwire between our house
and a friends around the corner of a horseshoe hilltop ridge in the
Los Feliz area of Los Angeles.  It had a little wire hanging out the
back so I hooked it to the antenna (what's matching???) and it went
way the hell off frequency.  I had to tune it back.  It got out but
not overwhelmingly.  You could hear it about a mile and a half in a
car.  The antenna went from a post on the back, upstairs porch to the
side of my buddies patio.  It really sagged in the middle but we were
up pretty high.  We used some old military copper clad wire we bought
at J.J. Glass Electronics in downtown Los Angeles.  My dad made us
take the antenna down because he was afraid it was going to pull the
side off of the porch.  He was probably right.  Just think of what it
might have done if it had been properly matched!
