I can confirm this. I've heard it on strong SSB signals and it's easy
to demonstrate with the XG2 signal generator set to the 50uV level.
The more aggressive the NR setting, the louder the strong signals
become. Using the XG2 and the K3's built in AFV meter, NR F1-1 gives
a 3.1 dB boost
hello all,
Anyone try this: listening a S7 to S9 signal (SSB) on any band with
your headphone, at this time, try to
enable NR, you will hear a really LOUD audio!
Maybe need firmware upgrade to fix it.

Hi all you K2 owners;
In the ongoing effort to preserve and protect our SWR and Power bridge
diodes,
would the installation of a gas discharge tube between the antenna connector
and ground as in the K3 be of any help in this battle?

Are you sure about this? A snubbing diode has to have fast turn on, but
slower turn off is not as much of a concern. A while ago I looked at the
turn on and turn off times for several diodes including the standard
1N4007 and found all sufficiently fast to work well as a relay snubbing
I have reported to Wayne that the Pre and Att memory goes across both the
receivers. I thought they were independent. He has responded that it is
under investigation. Perhaps this is the issue Jeff is bringing up.

1N4007 diodes have a notoriously long switchover time. That's what
makes them useful as a poor-man's PIN diode. They aren't quite so
useful in back EMF suppression, though.
If you use a fast diode, you should be able to keep the back EMF
voltage down to the forward-bias voltage of the diode
Thanks for bringing up the attenuation issue with using ant1/ant2. Has

There are couple of points to keep in mind if you don't use the AUX input
and use ANT1/ANT2 for both sub receiver and main tx/rx. They're covered in
the KRX3 manual, but in case you missed them:

There's one ... at least ... condition where the BNC input jack

One possible problem is that if you were to accidentally press the ANT
