KRX3 diversity receive

[VE3WDM]

I have installed the KRX3 and set it up with a separate antenna from Ant 3 at the rear or the K3. The diversity antenna is a dipole and the main antenna is a vertical. The meneu settings are as follows
1. ANT=BNC
2. KAYN3 has been calibrated.
3. SPKRS is set to 2 as I use headphones.
4. I used the K3 utility to download the latest firmware and the box was checked for DSP2 and KRX3.
 I am trying diversity for the first time today and I press and hold the sub button. I get the LINK followed by DIVERSITY. In the manual it says once this happens the sub and main are linked, that the sub is slave to the main. When I turn the main VFO the sub does not follow as if it is linked. Is this how it works or am I forgetting something?
Thanks
Mike

Mike,

When you say the sub does not follow, do you mean that if both VFOs are
tuned to a signal and you then turn the VFO A knob away from the signal,
the right channel still plays the same signal without change despite
turning the tuning knob? or do you simply mean that the VFO B readout
doesn't change, but the signals in the left and right channels both move
with the tuning knob?

If it's just that the VFO B readout doesn't change, that's normal. In
Diversity mode, both receivers are controlled by VFO A. The VFO B
readout is the same as it would be in a single-receiver K3, and has
nothing to do with the subRX in this mode.

There are two VFOs and there are two receivers in your K3, but there is
not a one-to-one correspondence between VFOs and receivers. The main RX
is always on VFO A, but the subRX may be on either VFO, depending on
whether you are in DVRSTY mode or not. The transmitter may be on either
VFO, depending on whether you are in SPLIT mode or not.

BTW, you do not need to set SPKRS to 2 unless you also have SPKR+PH set
to Yes. In particular, do not set SPKRS to 2 if you have a mono speaker
plug plugged into the rear panel speaker jack.

  Rich,

Just a comment on what you said here - ALWAYS use a stereo plug in the
rear speaker jack.
Using a mono plug has been responsible for the demise of several K2
audio amplifiers.
While this problem was supposed to be corrected with some resistor
changes, I would advise all to take the conservative path and change the
speaker plug for a stereo plug - of course, you would wire only to the
tip and the shell, so it is still a mono connection, but the plug is a
stereo type.  The open ring should not cause damage.
