Happy New Year to all.

posting for help I will do this year:-)
Anyone out there done this before?..perhaps you could pass on the wiring and

I finally measured the drift that I'm seeing with my K3. I tracked this
using the AFC function of Digipan while monitoring the carrier of WWV at 10

first 90 seconds, then over the next 5-10 minutes the rig drifts much more

I find the stock 2.8k sideband filter to be quite sufficient for AM talk or

I'd respectfully suggest that anyone who has made this as a serious
suggestion for SWBC listening, has never done any serious SWBC
listening ;-)
By all means, if you want to listen to AM SWBC (or AM on the ham bands
for that matter) you need at a minimum the 6Khz filter, and I'd
That will work too. but if you already have something in the Key In

Unfortunately, using the utility program to restore the settings did not
work. It was determined that the utility saved the code that had become
corrupted. So we had to do it the hard way. Even so, using the utility for
restoration of settings in most cases is a very good idea.

I agree with Mike that for occasional listening to AM stations outside
the ham bands, the stock SSB filter in SSB mode is fine. Zero beat the
station and it sounds OK. Switch to AM mode and it's too narrow. For
tuning around casually, having to listen to carriers as you tune is
annoying.

I can only compare the K1 and the K2. They are both great kits, but
after that they don't really compare. The K2 is a full-featured rig,
and the K1 is a special-purpose, trail-friendly CW rig. The K1sounds
great, and has filters, and what it does, it does very well. I don't

Jim,
On the back of the K3 is a 1/4 jack that says KEY.
Closing that with a key or a footswitch puts out full transmit power in CW
or SSB (and perhaps other) modes. It is separate from the connection for
paddles, or amplifier keying and I use it just as you suggest. Actually, I

Yep. Non-Region 2 broadcasters are moving up from below 7300 kHz to the
7300-7350 kHz range. Hams can celebrate. The 40 meter ham band is
