Nigel,
My spreadsheet that K7TEJ mentioned does not only address US versions of different radios. Where I know - or expect - a modification is needed, I have noted that. This was something Icom and Kenwood did in the 1990s and into the early 2000s with their VHF/UHF FM mobiles and handheld radios. Thankfully, those radios now cover at least 430-450 MHz in the 70cm band, if not the full 30 MHz band - ending the need for that modification.
That spreadsheet is not the definitive source for lists of radios capable of full-duplex operating. I believe there were many Standard HTs and mobile radios that could do that, but I don't have details on which models. There could be other radios from the traditional amateur equipment manufacturers that are also capable of full-duplex operation. I'm happy to add to what I already have, if I become aware of other models that can do this.
73!

But remember that the spreadsheet only lists "A" (US) models. The "E" variant (European) models will all transmit 430-440MHz without modification.
