I guess I didn't make myself clear. I'm thinking that I could use the FT-897 to transmit SSB to FO-29 and use the TH-F6A to receive SSB signals so that I would then have full duplex. Does that sound logical? Then I was wondering if de-sense would be an issue? Has anyone used the TH-F6A? Lee (Doc) Ernstrom Syracuse, Utah DN31 Sent from my iPad
