I have a friend who has one of these, and is looking to either exchange it for a VHF duplexer (160 MHz, capable of a split of approx. 800 kHz at 50W) or funds in order so he can buy a VHF duplexer.

If you have an interest in it, I can put the two of you in touch with each other. (He is not a subscriber to the list.) Thanks, Mark - N9WYS
