Bernie, If it's like my mid-90s vintage RM35M, there's a trim pot on the PC board, which appears trace-side-up when you remove the top cover. It's not the best design...would have been nice if they'd made it accessible through a hole on the case without taking it apart. (Or, even out of the rack!)
Look for it back a little from the edge of the PC board opposite the filter capacitor's screw terminals. The factory says it's adjustable 11-15V, but I think it crowbars at 15, so don't push it. 73, Paul, AE4KR ----- Original Message ----- From: dallasreact112 To: [email protected] Sent: Tuesday, November 13, 2007 9:38 PM Subject: [Repeater-Builder] Astron Power Supply Has any one had experience with setting output voltage on an Astron RM-50M power supply? I'd like to bump up the voltage to 14.4 V to override a diode junction loss in a battery isolator. Does it have the room to be adjusted up? Thanks Bernie Parker K5BP
