Thanks for the response Michael. Very helpful.
There are currently no repeaters in my area on channels 575, 600, and 675. But there are 2 repeaters on 725. If I understand correctly, I can re-purpose one of those channels to pick up the second 725? I can re-name one of those 3 channels, but is it possible to change the frequency to 725 with the appropriate tone?
I see RT Systems has the KG1000 software & cable. What's a bit intimidating is the installation on my MAC. I'll investigate further.
Thanks!
