I am beginning to wonder if my K3 Rear panel PTT in RCA jack has a
problem. It appears totally dead - I can't get it to switch the radio
to tx. Also, it has no voltage across it that I can pull down by
shorting the pins
I must have some configuration option screwed up, but have tried
several
I have learned that I should have 4.9V present on that line, and I
don't, so it must be a hardware problem. I will try to fix it next
time I open the radio up.
This list is great to solve problems lilke this. Thanks guys.

I once blew up an unprotected amplifier's output circuit when a flaky
antenna feed line opened with 1500 watts RTTY applied. Prior to
that, I didn't think I needed anything more than a hand on the drive
level control to keep my amp safe.
Now I make sure the ALC is there so the amp can cut tha
If you have another receiver handy that can tune 8.2 MHz, use it to
sniff at the K3 IF out. I think the signals are in the microvolt range.

I just assembled K3/100 sn1617 - it also came with KPA3 manual Rev D,

I don't completely follow your description, so can't comment on what
you are seeing, but many of us who are using the IF panadaptor are
using the wu2x version of PowerSDR, along with Larry Phipps'
LP-Bridge. This gives the best panadaptor I have ever used, and I
have been using them since the e
I had a bad encoder assembly in the K3 I assembled recently - I
proved it by swapping A and B encoders and observing the problem
switch with it. Elecraft shipped me a new one which fixed it (after
much sweat replacing it - that front panel removal is a PITA).
I suspect Elecraft is not checking
I think it would be a good idea if Elecraft would start checking
every encoder before shipping. It is VERY difficult to
disassemble/reassemble that front panel.
How about it, elecraft - can you start checking them there?
Also - do we need to be concerned that other components of the K3 are
no
Same here - just by brushing up against the cable I often lose
connection. Been a problem recently as I was interconnecting the K3
with the rest of the station. I think I will make a new cable
assembly and see if that helps.
PowerPoles are great for quick connect/disconnect, but in a radio

I don't use split much, but I constantly lose RIT. I want RIT on all
the time and it is a nuisance to have it turned off randomly (this
happens on both of my two K3's)

There is an official mod on the elecraft site to add the pull-ups
inside the K3 if you prefer that - look for the ALC mod.

I'd like one too. Though I'd settle for a soundcard based one that didn't
come with a whole screen

The knob is a disappointment here too, Keith. IIRC,
