Re: [Elecraft] [POSSIBLE SPAM] Common K3 failure modes???

Since buying a TS-890, my K3S is now a spare to it (although I doubt I'll ever need it) and my original K3, once a spare to the K3S (which I did need) is excess and I'm thinking of selling it.  But I'm wondering whether in today's climate, it might not bring more money as pieces than a whole.

I have also.  The K3IO module is pretty fragile, it seems.  Of all the requests I've seen here on the reflector over the years for a replacement item, the K3IO tops the list from my memory ... you can't just buy a replacement from Mouser or Digi-Key like you can the input diodes.  And when it

Re: [Elecraft] [POSSIBLE SPAM] Common K3 failure modes???

The only hardware failure I've had over the long life of my K3 (SN 4275) was the driver MOSFET in the KEY OUT circuit.  No idea what happened, but the transistor exploded.  Got it repaired locally. 73, Pete N4ZR Check out the new Reverse Beacon Network web server at

I have K3IO failures as well. Robie AJ4F On Wed, Jun 22, 2022, 6:57 AM Dr. William J. Schmidt wrote: > > My K3 failures always come in the form of either K3IOx failures (extremely > common) or the 10W module. Everything else seems to hang together. > > -Original Message- > From: elecra

My K3 failures always come in the form of either K3IOx failures (extremely common) or the 10W module. Everything else seems to hang together. -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Geert Jan de Groot Sent: Wednesday, June 22, 2022 3:30 AM To: elecraft@ma
