I just received my 2 UV-5Rs. I'm really impressed with all the features packed in this tiny radio. The led flashlight is great. The FM music option actually sounds pretry good for a tiny speaker. It took me a little fiddling to figure out how to program the TX frequency into the memory. YouTube to the rescue.
The radio seems to radiate power less effectively when transmitting above 150 mhz. Ladd channels etc... As soon as I get an adapter I'll hook it it up to my SWR/power meter and get some power and match readings at different frequencies. The supplied antenna is susposed to cover 137 to 174 mhz but I suspect it's centered in the 140s in vhf band. Nagoya does make a commercial version that is made for 150 mhz and higher.
