As a ham radio guy, I'm familiar with the range of UHF radios and that's certainly an advantage that I don't think BT will ever be able to meet no matter how good the technology gets. On the other hand, the full duplex of BT communicators for me far outweighs the slight range distance compromise. I've always been pretty happy with the the BT communicator range including the early Scala Q2's, the SMH10's and the 20's. For the most part its line of sight, sometimes more, sometimes less, but for the most part its plenty of distance for my wife and I and our friends. New certainly there are times range becomes an issue, especially when we are dual sport riding in heavy wooded areas, but we've learned to live with it. Now coming the other direction you have from UHF to BT, I certainly understand not wanting to compromise on distance. Not sure if you are aware, but if you already own the UHF radio's you were using with the autocomm's have you thought about complementing your Sena 20s setup with a pair of Sena SR10's which allow you add 2 way radio's to the mix to each of your headsets. They basically allow any 2 way radio to sync up to your Sena headset via BT, so you are still staying wireless. This gives you the best of both worlds with both BT communication and UHF communication right at your fingertips. Basically, you would use your 20s for the majority of your communication which gives you wireless communication, full duplex intercom, etc. However, if you got out of sight of each other or maybe you are in town and one of you takes a wrong turn where the BT won't reach, then you could easily use your PTT button to fire up the UHF radio and bingo, you have a great backup system to fall back to that integrates flawlessly with your 20s headsets. Best of all, its all wireless and the only thing you'd be adding is the SR10's + the necessary cables to your UHF radios. I've spent a lot of time talking on Ham Radio on my Vstrom using my Sena SMH10 + Sena SR10 + Yaesu FTM10-SR and this setup works awesome. Several of us have tried lots of different setups that involve VHF/UHF radios and this is pretty much near the top. Now I've never used an autocomm, so I can't compare there, but other ham guys are pretty happy talking to us on the air which says a lot. I actually got my wife to get her ham license and have a 2nd setup for her bike, but I could just never get her used to talking on the ham radio, so we don't use that as much as I would like, but it does work. BTW, what frequency range are you talking on on the Kenwood UHF radios? Ham 440, MURS, FRS, GMRS?
