John, I have been using my K3 (sometimes together with my second one) for FD

Switching the SUB between main and Aux makes no difference: there is no AF
other than noise and nothing on the S meter when B SET is pressed.

As someone who waited months after ordering when it was first announced, I
can say the wait was worth it. The integration with the KX3 and features
are well worth the wait.

I spent last evening checking the installation of the KRX3A. I did find one bit
of incorrect plumbing (in the cables that connect the KRX3A to the rest of the
K3S): however correcting it made no discernible difference.

Hi Bill
The documentation around this is a bit confusing, but my understanding is that
this setting defines where the SUB gets its AUX antenna feed from. It can
either be BNC (the Aux RF socket on the back panel), or (if you have the ATU
installed and therefore two ANT sockets) it can get it
Ref pp 43 of KRX3 Istallation and User Guide Rev F Dec 22 2010
ALWAYS Set ANT = BNC if not connected to KAT3.
Clarification:I believe config selection ANT=ATU may be inserting
attenuation during transmit in the KRX3 signal path to provide protection.
Make sure KSYN3 tmp connections

The config selection of ANT=BNC / ANT=MAIN does NOT actually select which is

can be physically connected to be used by the KRX3. If no ATU,

The information you have been given is correct but it's a challenge to
wrap ones head around the details, a couple are subtle.
It is ultimately the items you have installed (the tuner, with the

Hi Lou
I think the PS minimum load kit is different than the resistor change to slow
down the PSU fans. I have already done the minimum load resistor which helps to
reduce the birdies on 80 meters.
What I am referring to is a resistor change done in production which slows down
the PSU fans

I use my ductless hvac for both ac and heat. The unit is about 3 years old
and has variable speed motors in both the compressor and inside units. I
have never detected any rfi from the unit. I have a quiet environment, so
any noise is not being masked.

Make sure the TMP connector center section on the boards is not broken or
push out. Easy to do if the TMP tip not lined up into the connector.
Also make sure that the pins from the SUB to the RF board are not missed

Likewise there seems to be a lot of pessimism when a product is in back order
status. If I really wanted a product, such as my K3S, there was a backlog of
