This subject has been discussed before. There are
apparently fans by different manufacturers used in
the K3.
I'm fortunate ... the fans in mine (S/N 0056) are not

They are absolutely silent. Yes, they -do- run ... I've

Since you can access the M1-M4 buttons for 'playback' from N1MM for CW

line.

In theory of course it can be done from any logging program that
lets you send macros to the radio. All you need to do is emulate
button presses, which is exactly what I do with the Arduino. I
just prefer having a physical controller.

Is it hum or is it actually buzz? Hum is 60 Hz AC, but buzz will be
of various frequencies, and it is difficult to tell them apart with just

On KPA500 fan...
My fan will only kick on after a somewhat sustained signal. This occurs at
about the
one minute mark for SSB and maybe about the same for CW but my CW transmissions
do not always cause the fan to switch on. I monitor the temperature too and it
seems
to run cool.

I am posting this observation here only because I am using a K3. I do
not have any clue what may have caused this phenomenon and I'd like

Cary,
I battled a hum/buzz problem just two weeks ago. After almost a full day spent
hunting, experimenting, searching, and doing everything under the sun plus some
very helpful dialog from others here on Elecraft forum, the hum/buzz was
finally fixed.
I did not fix it, it just disappeared.
Took the mic connector apart, even the Heil mic (gasp!). Could find no short
on the connecting wires, although I did clip out the unused posts in the 8-pin
connector. Put it back together, connected it to the K3 and, miraculously,
like Phil, the hum/buzz is gone. Have no idea what I did,
LDE's do not change frequency except in very small (a few Hz). Someone was
retransmitting part of your call on frequency. Easy to do that. But he
mis-timed it. You weren't supposed to hear it. Just more of the nasty
behavior you sometimes see these days. 73, Guy

Yup. It would be easy to do, causes more interference than a carrier
(which can be auto-notched out), and creates additional QRM when others
on frequency call you out for being a LID.

Hi,
Did you use slow AGC and was the RX gain still reduced (from a strong RX

Hello Guys:
Anyone know how to have the sidetone volume on the K3 go higher than 60? Yes, I
am half deaf. The Kenwood HS-5 are nice and loud at 45 and the Sennhieser 240
also does fine. But neither are as comfortable as the AKG K240 phones. The AKG

Tnx

Do you have a saved config file from before this problem occurred?
If so, try loading it. (maybe save your current file first).
If you don't have an old file, save your current file, do an EEINIT. You
will have to set up some basic things, but should be able to test to see

Let me add to Guy's excellent advice something I ran into often when

And the failure will often be internal to the wire's insulation, so even if
