When trying to use the CW Memory Chaining function I ran into an anomoly in
that it depends on when you tap the memory M1-M4 button during the sending
of the message. Example.. If the memory contains my call K4PI.. I hit the
button during the sending of the 4 it comes out on the air as KSPI
I believe the problem I asked about concerning Chaining has been corrected
in one of the updates. Unfortunately I am running behind in doing these.

I set up the RX EQ for a boost at 400 and 800Hz for CW. I also lowered the
others which had the effect of reducing noise. The results were good. I then
listened to some SSB and realized that the equalized settings were the same
as I had set for CW. I couldn't find a way to have one group for CW

Hello,
Now that the cold weather is taking hold on most of the country, you will
find a bunch of QRP Operators called the Polar Bears wandering out in the
cold on December 13th for the PBMME.

Bear QRP Club link.
It works at 100W SSB with 10-20dB compression.
For CW at 20WPM you need to go down to 70W or so.
I've been testing the Gamma supply with my K3 on CW. It works very well at
95W down to about 15 WPM. I rarely send below 20WPM and at that speed, the
rig's full 100W can be expected. Even with
So, if you made it 19% longer with some zig-zags, it would be resonant in
the middle of the cw band and no need for matching, just connect to coax. I
imagine it's fairly broad band being so close to the earth.
