Thanks to the list for the comments and suggestions on K1 tuning range.
Good idea Ralph. If you can fine tune just a little more, you will find
even more CW up to 7123 or so. 7120 khz plus or minus BC QRM is SKCC
suggested freq. and quite a bit of activity up there. SKCC is a group of
over 1700 CW operators who have extended straight key nite to always. Same
rules as SKN, i.e. mechanical keys only. I have thought about a 100 khz
tuning range going from 7025 khz to 7125 khz but that would involve a new
xtal in the premix circuit. I guess I will go for 125 khz. This gives
about 12 khz per rev. Not too bad, I think. 73 - Rick -
