JA> Yeah - guess I'm thinking of the old US CB. :-) Yes, that would be a BIG duplexer. Many 10m repeaters go for multiple sites instead of a duplexer. As for UHF CB, well, the frequncy is nice to handle, but the split is wicked. I did read somewhere that the first time a cavity manufacturer was given the specs, they were like "Are you kidding?". The split is only 750 kHz on a 477 MHz carrier frequency. Much less than the typical ham or commercial UHF repeater. JA> To have had a repeater back in the day... Would have been, umm, interesting. I do enjoy 10m FM when the band opens. ....
