I have always enjoyed Ham Radio but have never had a good chance to have an inexpensive unit, and I ran across this BaoFeng UV-5R 136-174/400-480 MHz Dual-Band DTMF CTCSS DCS FM Ham Two Way Radio for only $39.99 at Amazon [amazon.com]
. I think I can learn a lot with this little radio, and yes, you do have to have a license to transmit, but I think this is a really good deal to learn a lot about the hobby!
I'm seeing info on this radio that you really need the USB programming cable [amazon.com]
and the CHIRP software to program it well.
