Good Evening,
The nets were cast and check ins gathered. There was a good showing for the
Sunday two days before Christmas. Hopefully all who tried were able to get our
attention. My rig did change keying speed once but I had just passed the net
over to Tom when the display showed SPd 17.
I finished K1 #2427 and actually made a contact to Austria with it Friday.
Today I added the KAT1 antenna tuner which seems to work as well (after I
remembered to move the jumper to get the power readings from the tuner...)
Overall a very nice package, but I have one issue I would appreciate so

Lyle, perhaps you have actually hooked up the softrock "panadaptor"
and found a problem. If so, let us know.
Otherwise, considering that the K3 is using a roofing filter which

Dave,
"simple" and "effective" are often antonyms and do not occur together
except in the most simple cases. Assuring that no signals are
inadvertently injected into the K3 IF OUT jack does not sound like a
simple case. Bite the bullet and do a good job of isolating no matter
what you use -

Hi Dave.
There is a Softrock kit specific for the K3 which includes a xtal at
32.7680Mhz, approx 4 times the K3 IF.
The Kit is not expensive around $15 US.
I have one here but with so many jobs I have not yet the time to get it
up and running.
