This is my second attempt, first one was sent, but did not appear to be returned by the forum :(
To Mike and Others, I am pleased to see someone put some information on a commercial diplexer for 2M and 70cm. I had a diamond diplexer, and work okay, but wanted better performance. I will look at the TXRX wed-site, and see what they have, and of course price. You did mention about building one, do you have information on the construction, and if possible the performance. Our group is using a Diamond X-500 at the top of the tower, and I want to run both the 2m RX (currently default) and the 70cm repeater off of it.
