I had this idea a while back, to thin out my stuff in what I think is
a useful and interesting way. Along the way I ended up having to buy
a bunch of new stuff as well (e.g. the brand new tune and load
variable caps). So take a look - might be a fun way to spend some
winter evenings.

Hey OM


I should has learned to play the guitar. Instead I got into
electronics built my first xmitter in '67 using a 6BQ5 xtal osc and
6146A final.
Everything was hot. I used series twist lock caps in the ps, B&W coil,
with aligator clip adjust, multi elmac plate and tune caps, a tv set
power xformer, all that on a punched out 5x7x2 LMB chassis. Even the
Key was hot as I keyed the screen of the 6146A.

That's pretty impressive, fitting that on a 5x7 chassis!

My neighbor gave me one of those 5 tube AM BCB radio kits back when I
was a kid. It was part of an electronics correspondence course he was
taking. The idea was to put it together breadboard fashion on the
schematic then when you got it working move it to the chassis. I
thought it was cool just keeping it on the breadboard and hauled it
around for years until it finally got stolen out of storage about 20
years ago. Over the years I had tested several mods on it. HF
converters, adding another IF stage, a BFO, Q multiplier and reworked
the series filament string for parallel operation. I'm sure if it was
still around I would still be tinkering with it.
