Did it transmit high power, without going down to mid-power, when the truck was off (12V)? If it did, it is the voltage when the engine is running. My ID-80 HT has DC power protection which is activated with 14V and above. When activated, it beeps and forces it down to mid-power. I suspect the same protection is in place in the 800. 73, -- JI1BQW - Kay Ishikawa ----------------------- Original Message ----------------------- On Wed, 26 May 2010 23:30:39 -0000 "w0rmt" <w0...@arrl.net> wrote: > So I took the radio our of the truck and plugged in into the control head and > power supply for my other 800 in the house and it worked fine.
