[Elecraft] Re: K1-2 No TX on one band

[Detrick Merz]

Well, I think I have this one sorted out.  Here's how it boiled down
for me, in case anyone else gets anything similar:

1) Reflowed *every* solder joint on the filter board.  Added a bit of
solder to the ones that looked like they could handle a little more

2) Reinstalled the filterboard and experienced *no* change (still
9.9:1swr, no appreciable power out).

3) Tuned around to find some kind of signal.

4) Repeaked the filters (they did take a bit of adjusting, and signals
got stronger)

5) Asked the KAT1 to tune.. it found 1.6:1 this time.  Tested
transmitting, and while no one responded, the rig was showing 4 watts
out.

So, I guess the filters were far enough out of whack to be blocking
the signals I wanted.  Adjusting them again seemed to do the trick!
Thanks to everyone who replied with suggestions (and, the "shadow" one
person saw turned out to just be a bit of solder resin).  Now, if I
can just find something decent on 15M :)
