some manufacturers are lower than this, and for AGM it is usually a
bit higher at 13.6 to 13.8. Check with the battery manufacturer to be
sure.
What you are trying to do is keep the battery fully charged but yet
not burn off the water nor damage the plates.

Just run the Transmitter Gain calibration for 5W and 50W using the K3
utility program, or manually as set forth in the Owner's Manual, p49.
This solves most TXG problems.

Hi Joe,
Did you make sure that it's opening the correct serial port? If
you're using a USB hub, sometimes the COMx port id moves around. If
this is the case, you'll have to sniff it out.
If it's a REAL serial port, sorry. No clues here on that.
You can set the COMx port from the K3 Utility,
troubleshooting advice for you.
Don't give up. All problems can be overcome. Call or email Elecraft,
and they'll help you get it figgered out.

Try adjusting the noise gate level up until the crackle disappears. If
you have it set too low, it doesn't seem to close quickly enough with
high background noise levels.
I had the same problem with a cooling fan behind me at an angle. Works
fine now. The level here is 18. Of course, YMMV.

I spoke briefly with Eric about the 2m module while we were both at

would be sometime in mid-September. I don't know the first order

enough to squirt the first
I like the limb you're out on.
Will there be a cursor function, similar to a spectrum analyzer - or
does the P3 auto-center frequency in the IF center? If the answer is
yes, text display of peak/average dB of a selected signal could be
done.
Maybe the cursor already exists and I just didn't see

I'm still evaluating the NR settings here. On strong SSB signals, it
sounds OK to me, but seems to limit or compress weaker voice signals.
I've been pleased with the improvement to CW signals, though the
settings available don't seem to change output characteristics much on
a strong CW signal.

You have to use the 6 KHz filter for TX on ESSB. You're TX is

All,
The 400 Hz and 1 KHz filters are 8 pole. The offsets (should) be
zero.
