Default Re: Midland Portapack 77-805 CB power meter problem

I've got one of these and although I have to admit that I've never studied the circuitry, I was always led to believe that the circuit had been 'doctored' from conventional design so as to operate safely into a very un-matched antenna. The SWR on the telescopic aerial will be all over the place as the unit is intended to be worn like a satchel with the antenna going up against the operators body. I use mine in the car sometimes with it connected to an old mag mount and it works great. I've never taken a lot of notice of that rather pointless four segment display. A very good radio though, with the hand held speaker used as a microphone via a matching transformer in the head.

EDIT: Don't leave the batteries in it when not in use as the on/off switch doesn't isolate the transmitter finals - or just pull the little plug out of the back.
