I reciently purchased a AG25 preamp for my Icom 706MKIIG -not knowing that these are only to be used with a limited few Icom radios. I wonder if anyone can tell me the power required so I can set up a ac adaptor with bypass switch to power the coax from my Icom 706? or perhaps someone has already done this and is using a AG25 with their Kenwood or Yaesu? regards, Elmer
