I bought a 706 abt 3 months ago, and used it till I removed it from the
vehicle before christmas. It was on a shelf and not used until today
when I wanted to use it again. I find that all appears to be working,

What is your SWR reading? This radio has an SWR foldback circuit, meaning
if your SWR is off the scale (too high), it will automatically reduce the TX
power to save the radio.
