[Elecraft] Elecraft K2 Power Readout Discrepency

Mon May 19 15:56:13 2003

Bob,
Thanks for your quick response, I will look at earlier mod proposals. First
of all, as Ron suggested, I will measure the output of the 5 V regulator and
go from there.
Another solution is buying and installing the KAT2, but that is another
story!

72/73,
Robert, PA0RBO
