Dear group,
If I wanted to make an external ALC cable for use with a linear, do I just
need to solder pin 15 to phono center, and pin 12 to the screen beneath the
phono cable's sheath for common?

Good Evening,
It got a bit late tonight. I was stuck in a book and time simply melts
away. However, twenty meters has been very good this week. Each morning I
have heard DX stations calling with very good signals. Finding a clear
frequency has become problematic some days but that is a go
Conclusion must be, never ever use 5.0W or 50W except
when calibration is needed.
Why cant power calibration be turned off? Then we would
not have this "source for trouble".

OK...so we can send RTTY using the paddle in. What about sending RTTY

Yes, but it was also phased in at Aptos on Rev A boards at some point so,
while all Rev A and earlier boards need the mod, the more current K3's with

Hi gang,
The weekly Elecraft SSB net will meet tomorrow (Sunday, 2/15/09) at 1800Z.
We will start at 14.316 MHz, and QSY if needed. The net control is in
western Oregon, but we will need a good east coast or midwest station to
relay a few west coast signals that may be too close to net control.
Spotted perfectly on a CW signal, I narrow the BW from .15 to .10. I
hear a click and the audio suddenly drops to about 1/3. S-meter
reading stays the same.
It didn't do this when the radio was new, but it has been doing it at

There is *one* Tx EQ in the K3, so
I discovered that my cw power issue was due to a bad power supply for my

setting. I still see a 50% higher power output in Data A mode than the K3

that with the XG1? I have both. Not worth trying to sell the XG1. So thought
it would be nice if it could be changed to 160M or 10M.
