Ok guy's i have a 2517 with an issue i have never seen before..Got this radio from a friend who bought it new never been hacked or anything..He had a very high swr and the radio was getting reports of distorted audio and carrier level jumping..Well i have the radio on the bench and the collector voltage on the 2sb827 regulator is going crazy from like 0.78 volts up to 4 volt's when it hit's around 4 volt's the carrier will come up but then it goes away and it does this rapidly..I thought he may have damaged a mosfet (Pulling Current from the regulator with a short to ground)But after replacing all the mosfets pre driver and regulator nothing has changed.The pll seems very stable and i have a steady rf according to my scope driving the mosfets also have checked for any cold solder spots and no joy there either.and the rf power control it's fine as well.Darndest thing i have ever seen..So after 8 hours of digging i need your help..Thanks for any input..
