Anyone have any experience with this model? http://www.mcmelectronics.com/produc...m_term=72-8110 These are competitive, and better made. Plus they are specifically designed for communications by a radio hobby friendly business. No financial interest. I do have an SS-12 which never even gets warm. http://www.astroncorp.com/catalog.asp |

Chances are pretty good of finding an Astron in any amateur repeater vault you go into because of their reputation of reliability. I have a switcher (SS-12). I'm a firm believer in digital methods to improve energy efficiency. 36 cents a KWH will do that to a man. |

If the switching transients can be suppressed enough to allow a quiet receiver, otherwise just save even more and go QRT. That's the point. When propagation's good I can work the East Coast with 80 milliWatts. If I was using my old linear supply I'd still be drawing 6 Amps from the mains. With my switch mode supply, low power means low power. I'm going to put all my EFX pedals on a switcher,too. I can hear a motor a mile away at the quarry. It is one of those 2 or 3 horsepower industrial monsters and it has brushes that arc. That's a quiet environment and the SS-12 did not raise the floor one bit. The antenna's 25 feet away, in all fairness. |
