Yeah the fans are pretty noisy especially when CQing without answers which keeps the amp duty cycle high. At least when you get answers the amp has a chanceto cool just a bit and keep it below 70C which is where the hyper drive fans come into play, hi. I'm still happy with the amp for several reasons but I still prefer tube amps.I thought I would have two Acom 2000a's but when I saw the new 1500 I figured I would take the solid state plunge for instant on capability but I still prefer my 2000.Tube amps have the same speed fans no matter how hot and how many CQ's you call. The 1500 sits on top of the Acom quite nicely though, that couldn't happen withtwo Acoms, hi. A friend of mine keeps his amps in the basement with his shack upstairs. He is awaiting his 1500 to return from Elecraft for a repair but I already emailed him and toldhim he definitely would like to remote the 1500 to the basement, hi. I could use the Acom more for running somewhat but I was giving the 1500 a pretty rigorous testover the weekend. I don't know how well noise cancelling headphones will do with the 1500 fans when they start singing over 70C. I keep the manual speed to at least2 while contesting and sometimes 3. It helps to get the temp to stay lower for longer periods while the duty cycle subsides. First big contest test of the 1500.

Fan noise...another issue. Usually for a cw contest I use some old ear buds. Not possible with the amp. Had to use the total ear muffs and still quite noisy. Did not effect my performance but it is annoying. I can not imagine what it was like before they released the amp to general public when they changed the fans...made them less noisy??? Still needs some work but at this point probably not possible. So looking for suggestions for reasonably priced noise cancelling headset with mic if possible. Hope we get full explanation of what gets changed in the next firmware release. Still smiling.
