Steve,
I'm just wondering if you use RX EQ with large gain settings. As I recall, the
K3 cancels those gains with the two narrowest Width settings (i.e., 50 and 100
Hz). This might account for at least part of the large increase in gain that
you experienced when you
opened up the Width
When I tune K3 to the carrier wave signal of a AM broad casting in LSB mode,
and then press NR, the AF output of K3 turns very very loud. AFV display will

The LMC660 op amp can have a tendency to oscillate when driving a
capacitive load (see the LMC660 datasheet) although it is normally
stable in the K2.
Before replacing it, try the following steps - check after each one and
stop if no oscillation.

Good thinking Chuck. I have the RX EQ set for band 4 at +2 and band 5 at +3.

You can abuse the breakdown voltage of a PN junction as long as the power

Did you check your CW key and/or paddle? I have had that issue when the plug
was slightly askew or if it was making contact. The error code indicates a

I think this thread has gone about to the limit, but, soldering is bonding
materials together with a eutectic material, in this case usually a lead/tin

OK, here the deal. My K2 S/N 6698 doesn't have the same freq offset on

Bud,
If the K3 is powered on with a KEY(or paddles) or PTT closure, ERR KEY
will result, and will not transmit until the condition is cleared. (but
connect a dummy load just in case).
I am not certain the LINE IN has anything to do with it, but if VOX is
on, the K3 can be keyed with the LINE
Mike,
First there is up to a +/- 20 Hz tolerance that can be attributed to the
K2 DAC, so dead nuts on may not actually be achievable, but you can
get close. First question is - what are you using for a reference? How
much do you trust its frequency accuracy? That is one potential source

See if you can isolate the problem - Turn off the K3 disconnect the computer
from the K3, turn it on and check the config menu setting for PTT-KEY. Turn
both PTT and KEY to OFF. Turn off the VOX. Turn off the K3 and reconnect the
