The volume knob is very tight. The potentiometer works well enough, but it is somewhat hard to turn. I think after using it for a few days it has loosened up a tad, but at first I thought it was going to break. It never did, and seems to be improving, but be aware of this fact. It might just be specific to this one unit I have, and not the model as a whole. I don’t have another UV-82 to test with.
So far I have only found one item that I do not like about this radio. To make it worse, the user manual doesn’t tell you this, so I had to Google it to find the answer. There is no apparent way to switch from Frequency Mode to Channel Mode. What I found is that you have to turn the radio off, then hold down the Menu button, and turn the radio back on. This will toggle modes from whichever current mode you are in, to the other mode (Freq/Chan or Chan/Freq)
This was a bit dumb. Turning the radio off? Really? But we have a button on the side for a flashlight, which you can toggle off and on, and into strobe mode. That is highly useful >.> – seriously, lose the stupid flashlight and make the radio interface easier to use. And PLEASE put the instructions for toggling between modes into the user manual.
