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

[Mike WA8BXN]

Get a mechanical timer, one that has the pegs in a wheel to set on and off
times to control a lamp etc. Set up an antenna relay that connects one
antenna when power is on, and the other when off.

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 my two antennas... 

 

Basically, I am manually switching from one antenna to the other on a 

reqular basis, keeping track of which time periods each is in use. 

What I'd like to do is automate the antenna switching on my K3 at 

periodic intervals. 

 

The question is, what is the simplest solution for achieving this? 

Don't really want to install some full-blown logging-control software. 

I am wondering if there is perhaps some little generic utility 

available that will send user specified commands over the serial port 

at specified intervals. Is there anything like that available? (Years 

ago there was a great telecom program called COMMO that could do 

this.)
