So after field-testing the KG-UVD1P, I have to say it was great. Reached everyone in the Rio with a generic stubby antenna just fine, and it worked very well car-to-car on the drive back with the stock whip antenna, not quite line-of-sight distances. Though to be fair, I don't know what the other guys were broadcasting power-wise with their Motorolas; as far as I know they were picking me up fine from 1-2 miles at my 5W xmit. Battery life was easily an entire day with the stock 1700mAH one. This radio's a keeper.
Thanks for the informative reply, pretty much what I figured. Of course, transmitting on any frequency I'm not licensed to is illegal so it was more of a theoretical question. What do you think about rx on frequencies outside of 2m/70cm, could the radios physically do it?
