[Elecraft] Antenna comparisons, WSPRnet and timed serial port macros

[drewko]

Brian,

Yes, I want to send the ANT 1/2 switch command to the K3, say every
quarter hour. I believe there is no serial port rig control from the
WSPR software to contend with, just the tones from the soundcard that
key the rig periodically. 

So, I just need a utility to send the ant switch command over the
serial port to the K3 at fixed intervals.

Actually, I have found an old copy of COMMO that may run in a DOS
window. I'll try it later but if someone knows of a more recent
similar program pls let me know, thanks.

73,
Drew
