I'm surprised to find the F6 has been around almost 4 years and the other comparable units are about as old. Mfgrs aren't introducing radios like this any more. I wonder what's up with that. And I have to say the reviews linked above aren't all that flattering. Is 222 mhz very active in most places? Buying a tribander hadn't really occurred to me before (I just wanted 2m/440). Does the F6 have a way to send DTMF tones? Does anyone care about that any more?
