Take the top cover off the radio Charlie and check for nearby connecting wires contacting the fans - when they do you get an alarming buzz but if the degree of contact is very slight I presume it may just sound like a 'normal' noisy fan. The K3 fans are completely noiseless.
BTW you don't have to wait for the temp to rise to check the fans 'cos there is a menu entry (Config - KPA3...??) where you can test the 4 speed settings of the fans. I always check this after being inside the radio to make sure I won't get a fright half way through a sessions when the fans come on.... 73, Stewart Rolfe GW0ETF Missouri Guy, N0TT wrote: > > I was trying to ferret out some weak signals on 160m when > the cooling fans switched on, making it very hard > to hear over the "whine" of the fans (or fan) even through > the padding on my headphones. > > Has anyone tried to quiet them down with vibration > isolators, etc? > > Charlie, N0TT > _______________________________________________ > Elecraft mailing list > Post to: Elecraft@mailman.qth.net > You must be a subscriber to post to the list. > Subscriber Info (Addr.
