I used my new KX3 (SN 2282) in the recent WAE RTTY test as part of an SO3R
setup with
2 K3s, and wanted to record my impressions. The KX3 at 5W was driving an
amp to 100
watts, and contributed 298 q's to my total. The KX3 had the per band

goes to 7 S-units?
Take the meter out of the equation and listen to the signals. Try to find a

I've heard there are changes to the KX3 RF board beginning with serial

Could Elecraft please detail the changes so they can be recognised? I am
about to build a KX3 with a serial number just above that figure and I'd
like to be assured it's fitted with the new RF board.

QST review reported lower numbers on the lower bands, and the yahoo KX3 group
contains mods for 80 and 160m. It seems that the mods are for HPF filters so
it is possible that the current components cause an attenuation.
Usually sensitivity on 160m is not a problem unless one uses a receive

Any ideas?

Should be very similar on all bands. But if it would be lower if you
had MENU:PREAMP set to 10 dB on a particular band. The default is 20
dB, which results in S9 = 50 microvolts (approx.).

Hi All,
This info (see link below) was just passed on to me via GQRP-L.

There are still a lot of missing details, but it's hard for me to see how
this rig competes effectively with the KX3.

Many thanks for your answer and your ideas! Yes, i agree, this task

To use KPA100 with an other rig I would like to fully control it over

Hello,
I'm doing my first steps with my KX3 S/N 2294 ...
I noticed a click at the end of each given dit and dah in my headphones.
With NR it disappears mostly. With ATTN it disappears completely and
with ATTN off and PRE on it's much louder. I tested a KOSS Porta Pro and
a Sennheiser HD 485.

From the manual:
Most calibration procedures use Tech-Mode menu
entries. To enable these, set CONFIG:TECH MD
to ON. Set TECH MD to OFF afterward.
So if Tech mode is off I don't think the Tune button should not have
any effect on the Calibration.

Hmm, I'm not sure that's a reasonable assumption - the manual is
telling you that there are some menu items that you'll need for some
calibration procedures that are only accessible in tech mode, but
that doesn't necessarily mean that the calibration logic is linked to
tech mode - it may be; I
Geoff,
I believe the key to your question is found in the menu explanation for
the TXGN menu entry.
From that description, I conclude that the magic is in having the
power setting at 5, 50 or 1.0 mW. The gain constant is only updated
when Tune function is activated and one of those 3 power
Bill, you said in part:
It is a mechanical problem within the mic, as other mics do not do this.
You are partially right. The word is *SOME* mics do not do this. I have
had both hand-mics and desk-mics do it. AND, it was not only a spike; it
was during transmit if I changed the pressure
Are you driving the KAT500 with at least 10 watts of RF (20 is required for
the best tuning action)?
There is no report on the K3 display when the KAT500 comes on line like the

Be careful with silicone. Back in the 70's, give or take, it was discovered
in a lab that silicone widely creeps and gets into electrical contacts and
can cause circuit failures. The source was good. I won't let it in my

Bill,
I sent that last post a bit too soon. I thought of something else.

As a Signal Source I used the XG3 -73dBm (50uV)

Measured on 3520Khz S-Meter Reading S5 3650Khz S5 hmmm??
This is similar on all Bands...
