This afternoon I installed the new firmware and IOC chip for the K2 so I can
use the KAT100 antenna tuner.  Since I had the control board off I also
installed several of the mods for the control board.  When one installs the
latest firmware and IOC chip it is necessary to realign the VFO and filters
so I decided to try the method suggested by Steve GU3MBS in his 29 Nov 02
mailing to the Elecraft List.  Basically it consists of zero beating the 4
MHz oscillator against WWV at 20 MHz on another receiver.  Very easy to do
and when the filters were reset I can get within 20 Hz on the display with
zero beat on the K2 against WWV.

Just wanted to pass along the success I had with Steve's GU3MBS cal method.
