Jim,
Your PA transistors had some collector to base leakage which increased
the voltage on the base. The usual case is that the base voltage goes
much higher and destroys Q11 and Q13, but it seems you are OK.
I have seen that condition many times over the years (I have over 1000
repairs
Other problems discovered along the way with this partially
assembled kit.
Hi Don,
Thank you so much for sticking with me on this.
K2 #2438 Ver. A with no updates.
I had measured 1.48V at bases of Q7 and Q8. (installed.)
And as you suggested I removed the PA transistors
and now measure 0.63
I may have one you’re interested in. Email me at n1...@arrl.net

Perhaps you have a recent configuration backup. Load that into your K3.
Should get you back to a working radio.

OK, I have done some fat fingered thing to my K3. For years I have been
running RTTY in FSK D mode. All of a sudden, right before Field Day of
course, it decides that it will not transmit in that mode. Not using PTT
over com port, direct using my home made interfaces I have been using for
years or
Hello John is that not from Inrad who are a different vendor to Elecraft? Or
did Elecraft supply Inrad filters at one time? I have no idea I've only just
started looking.

The old 400Hz filter was a 8 pole variety. It’s been replaced by a new and
probably better 6 pole filter. As have several others.

The KFL3A is an 8-pole filter.
The KFL3C is a 6-pole filter. In a 400 Hz bandwidth, performance will be
virtually indistinguishable from the 8-pole.

The new Elecraft site is a little vague regarding roofing filters so I am
going by memory. I have two filters in my cart KFL3A-2.8K-IR and KFL3C-400
for my third K3S. Before I hit the purchase button I want to be sure that
these are both 8 pole filters.

Will it be possible to reposition the second panadapter ‘under’ the first
instead of beside it when viewing it on a PC monitor ?
