I just uploaded K3_EZ, a Windows application I've written for the K3
(Apologies to K3EZ!). It provides:
* A set of 5 'memory-like' frequency storage areas per band and mode
* A frequency and mode database, useful for SWL frequencies
* A graphic interface for the K3 RX and TX equalizers with
S/N 00929 /w FW 2.76, 6.0 kHz filter. Confirmed TX on switch from DATA to
AM when VOX on. Getting typical AM carrier output for about 1 second.
Happens from either front panel mode change or PC control (two different
programs).
Happens from DATA to AM and DATAR to AM (I tried all
changing VOX gain did the trick.
It's not 4/1/2009 already is it???

There has been much chatter about the K3 EQ lately. I've written a small
Windows application that helps to 'manage' the equalizers. This is a work in
progress, and I'm not much of a programmer. You should take this to mean:
Caveat Emptor!
The application is being used by about 20 people now
FWIW, I've been using N1MM Logger keying via the serial port (and earlier
via parallel port) since 'day 1' of Logger on many different PCs, WIN98 thru

Per the Owners Manual Version D, page 51, ESSB mode has it's own TX

ESSB enabled (CONFIG:TX ESSB ON), but there is no * indication in the EQ
setup display (MAIN:TX EQ).

I would like to be able to GET and SET the individual equalizer settings for

include the B display as well?
Or... am I
I miss dedicated band buttons even though my main rig has been a K2 for the

though.
But (you knew this was coming), the very thing that makes the Quick Memory

After a power off and a radio club meeting (probably not relevant), my K3 is

each.

A few days ago I fixed a problem on my K2 (low output on 15/12/10).

The KRC2 does not need the 8R input for use with the K2 or K3. Look at

Thanks to Philip WD8QWR I have learned my K2 and KPA100 are working as
they should. Now to re-do the FWD and REV adjustments I have been

I doubt it's the cover holes. I've done some testing with the top and
bottom covers off while interfacing my newly built K2 to a 1500W

Is your problem band sensitive? Is your antenna resonant? I would

I'm considering a K2. The power out spec says .5W... how much less?
I'm not much of a QRP op, my amplifier only needs 100 to 150mW. If the
K2 will reliably go to 100mW or less I can skip inserting an attenuator
and simplify T/R switching.
