Thanks to everyone who shared their opinion of my dual UV-X4 full duplex
project. It was very interesting to read the variety of opinions people
have. Back in the day we used to say that if you had a room with 10 hams in
it there would be at least 20 strongly held opinions on any topic. Glad to
see that is still true today. The first UV-X4 is great and has worked out
so well that I ordered the second one and hope to work you with the full
duplex setup someday soon.
