Well, when I got the photocopied sheets from Uncle Ed in....90? he had
addressed some issues with what looked like a black crayon or grease
pencil, an orange crayon, and penned-in notes I had trouble making
out. Up until then I hadn't done any major modifications to any gear,
but it didn't take me long to change my tune. Ed was my first or
second contact on the air with the rig, and when I asked how it
sounded, he replied "well....it sounds like a stock KW-1. You need get
in there and change a few things...." followed by your mods. I did
mess up a bit around the clipper due to the crayon factor, but cleaned
it all up nicely when I had the audio deck out last February.

I'm okay with it the way it is now, drilling/blasting/outboard decks
are more than I care to attempt. Still have a bunch of RCA 845s NIB
though, so...

That's gotta be tough to see your pride and joy in decline. Maybe it
will find its way back to you someday.

I'd like to hear more about this sometime.

Ironic....I found #89 in an antique shop deal in August of '88. I was
27 at the time. Didn't get it going for another couple years, though.
Bill Wheeler was the final savior, helping me locate an open 4-pie,
duo laterally-wound bias choke for the 4-250s. He was on one end of
the long distance call looking at his schematic, I was in VT looking
at mine. Ended up being an easy fix, and ol' 89 returned to the

A grid short in one of the 250s took it off the air in '92, and life
kept me busy for a while beyond that. Hearing the first Heavy Metal
Rally got me back after it, replaced the bad tube, a broken plate
blocking doorknob, and swapped out the 872s for 4B32s. Had it working
again that December, and finally back on the air in March of 2006. A
few issues since, but I enjoy having it back online and have no desire
to ever part with it. It's on the air regularly, and will be as long
as time and conditions permit.

Think we either worked recently or at least I heard you up around
3870-3885 one evening. The new call sounds very familiar. You used to
have a K5 call, if I recall correctly.

Good stuff! Hope to hear you soon!
