There is a much newer one in QST in the last 18 mo or so don't remember any of those on it but maybe the Daiwa maybe a different model.

I use it when operating away from home. Nothing can beat the small size and weight. 73 Reinaldo, YV5AM -----Original Message----- From: Dave Hachadorian [mailto:[email protected]] Sent: miércoles, 12 de junio de 2013 15:28 To: Elecraft Reflector Subject: Re: [Elecraft] Power Supplies for K3 It was interesting to re-read the ARRL reviews of some of the switching supplies: http://www.arrl.org/files/file/protected/Group/Members/ProductReview/pdf/pr0 001.pdf The switchers were fairly RF-quiet at low current draw, and then created more noise as they drew more current. This is fine for the usual single-transmitter ham station, but could be an issue in so2r or multiop. I use a single Astron RS-35A analog supply for so2r with two K3's. It works great, and it is a fail-safe way to ensure that both K3's can not transmit at the same time. The supply will simply groan and give up! Astron linear supplies also have a simple (internal) voltage adjustment, so you can pump the voltage up to 14.5 for reduced IMD.
