Thanks very much for that info Eric... I picked one up for the right price and was wondering if it would be of any use in our MSTR II repeater system. But, it sounds like it is not... Interesting thing tho.. Has two directional couplers built into a small box and a nice meter. The two couplers are probably calibrated for the power set functions. One high and one low.... Would sure like to of had a schematic for it.... Oh well flea bait now... thanks 73 Doug
