I read the Eham reviews about how quiet the fan is and that it seldom even runs so I bought one. I used it to power the K3. The fan came on after about 3 minutes of receive mode operation and it was louder than anything else in the shack. I hate fans, except when I'm sleeping! The fan attempts to dischage out the bottom of the supply (strange). Also, the voltmeter stayed pegged at 15v however the voltage output was really 13.8. I had no RF hash although one time I held my AM transistor portable up close to it and it really wiped it out but so will most switchers. I unhooked the fan and ran it that way for a few weeks until one day the over temp. sensor shut it down. I also have the little MFJ switcher and it performs just as well and cost less but it too has a disgusting little fan. Finally, I went back to my Aston 35m which has no fan and helps hold down the desk. Ahhh....No noise, No hash....Just nice clean DC. 73 Steve N4LQ ----- Original Message ----- From: "N1JM" <[email protected]> To: <[email protected]> Sent: Sunday, May 23, 2010 12:17 AM Subject: [Elecraft] Samelex Power Supplies with a K3
