Ray,
Tks again for the idea. I now have the batch files set up to switch
the K3's ANT every hour, half-hour or 15 mts while WSPR is running.;
Even with dummy loads connected I'd hesitate to hot switch ANT.
Perhaps could try it while transmitting at 0 watts?

I've been doing some performance comparison between two antennas I am
using. I'm compiling data of my WSPR transmissions and spots over
periods of many hours. I got a little carried away and made up a
spreadsheet to compare reciprocal signal reports as well as the
performance differences between

His simple method of doing echo hello or your command string to
com1 would probably work. You could then make that a batch file to

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
Ray,
Thanks! That's what I had in mind... I believe it is the AT command
(not ON). Also, SCHTASKS perhaps...

no other software needed.
My only question is: what happens if the K3 receives a serial command
to switch ANT while it is transmitting? I assume the
