[Elecraft] Interesting QSO

[Wayne Burdick]

I just finished a QSO with a QRP station in Bend, Oregon on 40 m that was memorable for a couple of reasons: First, that we managed it all despite awful atmospheric noise and poor propagation, and second, that it highlighted many the K4's tools for digging out weak signals. 

By the end of the QSO I was configured like this:

- diversity mode (wire antenna on main RX, vertical on sub)
- 100 Hz primary RX filter bandwidth
- 50 Hz APF (audio peaking filter)
- NB & NR on
- CW center pitch dialed down to 400 Hz

That final setting may have been optimum for my hearing range (we all lose higher-pitched response as we get older), but it also seemed to keep the week signal highlighted during static crashes. I'll be experimenting with this on DX signals.
