Wow, you amaze me Brandon. Thanks for straining the brain on this thing. That transistor is supposed to sit like it does, as it uses a metal strap to hold it against the heatsink. I may open it up again if I get more curious. My little 4 amp power supply is all I was using, not my 25 amp unit (I...

Well I took it apart just for pictures. When I power it "on", it pulls about 1 volt from my power supply but I haven't tried it with a radio. I would venture to say at least one diode is probably smoked. The circuit traces are SUPER thin and easy to hurt.

Oh it is close but is separated. The DMM tested that, as I was questioning it also. I just got it back together, tomorrow maybe I can pull it back apart and get the group a few good pictures. It powers on but doesn't transmit. It does Recieve in the on position tho. It pulls about 1 volt when...

I took a couple pictures but it wasn't for showing the whole board. Not much to it. Mine had a burned circuit trace off of the base of the transistor but fixing that and the new 1307 didn't fix it. Thanks for your schematic! Marty

I have one. It uses a MS1307 transistor. Mine gave up so I opened it up yesterday and replaced the transistor but I think one of the diodes got hurt. I need a schematic also. 73's
