[WriteLog] Any new thoughts on "stuttering"?

[Randy Thompson, K5ZD]

After 2 years of using WL in AFSK mode, I finally got busy last night and
wired up FSK.  If someone had told me long ago that I could just take the
same transistor circuit I use for CW and move it from pin 4 to pin 3 on the
COM port, I would have done it long ago!

Anyway, I also noticed that the transmission time in FSK seemed to be
shorter than I am used to in AFSK.  Didn't look into why, but hope that
extra 1 second less per transmission will help lead to more QSOs!

See you guys this weekend.

Randy, K5ZD
