Ohhh, I suppose most on the list have been bitten by a "shock" either
ac, dc, or both, as have I, but if you havent been the victim of an
R.F. burn, don't worry about it...it just burns a hole thru your flesh
and self-cauterizes. That is what a cauterizing devince does, in fact.
I was, of course, kidding, especially at these power levels. At the 
levels (low) that I have been hit, either if just feels like the metal
you are touching is physically hot, or it burns a neat little pinhole 
in the flesh, but no blood due to the cauterization. Especially fun if
your mic has a plastic PTT button, and you push it to xmit, and get those
nice, moist lips near the metal microphone face. A quarter wavelength
piece of wire (counterpoise) drizzled wherever you can fit it in, and
attached to the transmitter may cure this.
