Every amplifier has some level of fan noise. My new KPA1500 is seriously quieter than my former Expert 2KFA.
My Henry 2K Ultra fans were so loud that I couldn't keep it in the radio room. Luckily I had the remote version. My Harris RF-3230 (all solid state) had 8 six-inch muffin fans! It sounded like a DC-9 warming up for a takeoff. I was two rooms away from the shack and I could still hear those fans! I run my KPA1500 at 1500 Watts SSB/CW and I have never heard the fans go past setting #2. If you want to run 1500 Watts of RTTY or AM, then expect the fans to be running hard to keep the amp cool. If you want a quieter shack, put the amp in another room. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
