A word of caution is in order. SGC advises against the use of switching supplies for their SG-500 SmartPowerCube amplifier. The recommended supply is a stout battery with a charger to keep it topped off, or a beefy linear supply. And I believe running the rig and amp on the same supply could be problematic if the regulation is not really good at handling transients. I occasionally use my K3 with the SG-500 and use separate power supplies for the rig and amp: An Astron RS-35M for the K3 and the SGC PS-50 for the amp. A pair of PS-50s is recommend for high duty cycle modes. 73, Gus Hansen KB0YH ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
