Steve, W9SH had a "simple voter" that required no hardware. I was always tempted to give it a try. His site is down, and I am not where he is these days in terms of development. But if someone who knows how to reach out to him, and could convince him to throw that code on github or something for posterity, I think that would be good. https://web.archive.org/web/20170306120829/http://www.xelatec.com/xipar/simp... I also be curious to hear from anyone who has tried the simple version. I tried to drum up some local interest in the past so I'd have someone to test with, and that never went anywhere. I was planning on using Ubiquiti wifi gear between the sites so that would eliminate the variable latency of routing over the internet for the receivers. I'd still be interesting in messing with it if the code was available. Mostly for learning / experimenting.
