The amp that Don mentioned is the SGC SmartPowerCube, which is a very good ham radio power amp. I used one for almost a decade in my shack (base station, if you will) and occasionally portable, though never mobile. The amp is solidly constructed, auto senses the frequency and does band/filter selection on the fly, and protects itself from abuse extremely well. The SGC product line was designed for the hostile marine environment. The amp is definitely not a CB brick. The SG-500 works very well on SSB as well as digital modes, but it was not designed for full break-in CW. I had toyed with the idea of modifying the keying circuit for QSK by using fast vacuum relay switching, but dropped that plan when Elecraft announced the KPA500. (I sold the SG-500 to a friend who has little interest in CW and a need for more power in his mobile station, and it has served him well for several years.) 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
