The radio says 13.8 v dc but if I get a 12 volt power supply will it put out the same wattage at the radio? Astron RS-20A, or a RS-20M if you want meters. That'll handle your 45 watt radio. It's a 12 volt power supply that is internally adjustable up to and above 13.8 volts. Get the RS-35 if you plan on adding an HF rig to your station. Astron is standard equipment on many radio desks. ac6xg I agree with Jim about Astron. Been using 'em for decades. Simple, robust design. Zero failures. The voltage conundrum I believe derives from the necessary voltage to charge a 12 volt battery. Gotta overcome that old internal resistance; Turns out to be about 13.8 volts. I don't know of a "12V" ham rig that would care about the difference. Get outside the manufacturer's specified range (RTFB) and you may not have a warranty. 73 H., NQ5H |
