Hi all,
There were some complaints about spurious DSP/DAC products *above* the K3
passband response.
The mentioned (beta) LPF board is only meant to supress those products.
It does not alter the K3 passband AF response or character.
If you don't hear any spurious above passband this LPF is not
Hi folks
K3 going perfectly fine here.
Just curious about an odd audio buzz
in the rear of the chassis under heavy
SSB modulation. It sounds like
transformer or frame slightly loose,
nothing appears loose or un-done.
Noticed when using the M1 audio
record - playback, so normally don't
hear it
Can you damp it by putting your hand on any of the chassis panels?

Thanks so much everyone for your responses.
And huge thanks to Don.
He gave some great troubleshooting advice.
At it turned out, the 3.3K resister in the swr circuit went also.
I should have ohmed out all of the circuit when I replaced the diodes.

The frequency is 3630 KHz plus or minus the QRM.

Allan,
No problem - those are via holes to carry the signal line from one side
of the board to the other. In the particular case of those two holes,
they connect the DB-9 pin 9 to R1.

Wayne, I have two questions concerning the upcoming panadaptor:

2. Is the panadaptor likely to be available in time for the California
QSO contest (1st weekend of October)?
I'd be happy
Yes you're going to need the IF out and I highly doubt it'll be
available by then. But I guess we'll see eh? I think anyone in a hurry
would be well served with an LP-Pan (and you're going to need the XVRTR
interface for that one too).
You may want to be careful. I bought my KXV3 interface
Last I heard I think Elecraft will even sell new boards at near cost if
you want to follow the upgrade path. That is if you're willing to send
back the previous board. They may even do that if you screw up an
upgrade with a soldering iron but if you're not confident then meh... no
point in doing
