The KX3 DSP has a special effects (AFX) mode by which higher tones go to one
ear while lower tones go to the other. The K3 does not.
Is there a reason why the K3 can not have this choice? If it can be done, will
it?

FWIW ... W5YA 3AB (QRP) was an all Elecraft K3 entry on field day this year.
The performance broke the previous category record set by another all Elecraft
team, K7EAR, in 2005. The K3's performed flawlessly.

Quick question:
The paddle for the KX1 (which is available as an accessory) what are the
dimensions of the square block out of which the stereo plug comes? My question
is generated by wondering if this key can be plugged into my ATS3B and still
permit the power plug access to its jack which

For my pair-of-K2's in SO2R, I have routed the audio in such a way that I have
a balance control with the audio from the two radios. I call it a mixing
control. I find that optimum is achieved when the full strength audio is in
one ear, and that same audio is
The problem was k3 instead of K3 however, that error came from clicking on
Elecraft links.
From Elecraft main page I went to the K3 page.
From there I clicked on firmware and software upgrades.
From there I clicked on beta release and instruction.

Since updating to FW 2.38, Hamradio deluxe is no longer able to connect with
the K3. It says can't read K3 frequency OR the K3 is in Memory Mode,
whatever that means. The Elecraft Utility sees the K3 just fine.
Has anyone encountered this and resolved it?
tnx,

Thank you. Indeed, the radio and HRD WERE on 4,800 baud rate. With the FW
upgrade, the K3 switched to 38,400 without my notice, and HRD had to be told to
make that change. Now, copasetic.

the new version of the narrow filter; at the noise floor the filter is half the

Thank you for various replies. For others who may have the whining power

It turns out that one group of these power supplied were made with an incorrect

clearly marked,
That which sets these radios apart is their relative immunity to blocking and

Some headfones have MUCH more gain with the K2 than others. the Kenwood HS-5
is a low impedance phone. I put it on the speaker jack. with that, I have to
turn the AF gain down to almost 8 o'clock and the RF gain down to about 10
o'clock to keep from blowing my head off with volume.
the HS-5
the K2 does not have two rcvrs for split operation. therefore, when working a
DX-pedition, one pushes and holds the REV button to listen in on the pile-up,
but can't do it well because the other VFO has the same narrow settings as the
VFO listening to the DX station.
