I'm interested in comparing the performance of two antennas using my K3S and WSPR software. I want to automatically switch the K3 antenna between ANT1 and ANT2 every 10 minutes for 24 hours, while listening to the 40-meter WSPR frequency.
I have WSPR running fine on the K3S, but I need a way to alternately send AN1; and AN2; to the serial port. I tried to use SerialSend (http://batchloaf.com), which is a program that sends a text string to a serial port. The string "AN2;" sent, but the K3S did not respond.
If I can get something like SerialSend to address the K3S, then I should be able to use Windows Task Scheduler to alternately execute one of two batch files to send the two commands every ten minutes.
