Well, yes, but using split or fake-it you could be 100KHz off and still be transmitting a perfect signal.
Didn't take long to get a 40M FT8 QSO at 3KHz this afternoon when the band was essentially dead. It all depends on the _other_ guys receive capabiltiies, and that's not something we can control. 73, Willie N1JBJ > On Jul 9, 2021, at 3:58 PM, Al Pawlowski <k6...@almont.com> wrote: > > I agree getting newer equipment regularly can be a problem.
