[Elecraft] K3/N1MM, freq jumps etc in CQ WW CW

[AB2E Darrell]

Wayne,
I had not known of this issue previously (having just acquired my K3 in April), but can confirm the same behavior this past weekend in CQWW CW as reported by Ignacy and I was using version 5.14.

It was intermittent and I could not pin down the problem during the contest, but the PTT would hang on returning to receive, sometimes 3 or 4 seconds. Other times, normal return to RX.

Setup this past weekend:
K3/ SPE Expert 1.3K-FA
N1MM+ Logger

Thanks and 73,
Darrell AB2E

I though we had fixed this for all remaining cases in rev. 4.55, but I'll re-list it.
