WOW!!!
This building project has been fantastic. I've certainly learned or
relearned heaps...
Thanks to Elecraft and all those who have helped me along the way, I am
extremely happy with results.
Everything is now complete and all seems to be working well but I can't
recall if I did CAL PLL
I made this video today while monitoring K1N working a JA pileup. It
demonstrates the value of the P3 panadapter in finding the station the DX is
currently working and determining if the DX station is using any type of
tuning pattern from QSO to QSO. Freq: 24.898 Mhz CW at 2345 gmt Feb 5,

John,
Yes, just push and hold the BSet button (the number 1 on the keypad). The
main VFO will now say b SEt, and the S meter is reading the sub receiver (also
make sure the sub receiver is turned on to do this).

Kev,
Great about your K2 completion.
For doing CAL PLL again, check the accuracy of your K2's frequency. Do
that on the highest frequency you can receive a known frequency signal -
as long as that frequency is in the 17 meter band or lower. If the
frequency is within 20 Hz of the correct
The charger is a 200 mA constant current charger. Either on or off based on

I understand the reason that the S-meter and panadapter don't agree. I was

Your real answer depends on your particular hearing loss, so no one else
can say what your particular desired pitch can be.
I suggest you experiment with different pitches in real time CW QSOs.
Tune the station to the pitch that you can copy best - then figure out
what that audio

Not only that, you can set up one PF key to toggle between two settings, so you
leave the other PF key free to do something else.
Here is an example of a toggling setup (it’s for KX3, but the same principle
