Don't know about your radio, but...

I found a dual USB (1 amp and 2 amp) adapter that plugs into a 12 volt
source in the auto section at Wal Mart. I wired in a 12 volt lighter
plug with a toggle switch to control it and glued it to the side of my
panel. It powers my Streak and has a phone charging cable should I need
it. Cheap and effective.

Can anyone recommend a 12 vdc to 5 vdc USB power source I can use to charge an iPhone in flight that won't break squelch on my glider's radio?
