Sub RX Noise Blanker - 3051

Hi Folks

I can't seem to get the Sub RX noise blanker to function.
Working fine on the main RX.

When swapping to the Sub the NB icon is not showing and
cannot be toggled on.

Ver 3.27

thanks

Paul

Holding BSET will allow you to set NB/NR on the subRX.

Hi Paul,

I just got stumped by this, too. In order to turn the sub RX NB on
and off independently of the main RX, you have to set CONFIG:VFO
IND=Yes. This allows the main and sub RX to be on different bands (so
pay attention when changing bands!) If CONFIG:VFO IND=No, the sub RX
NB is supposed to follow the setting of the main RX. At least that
what I *think* the intent is. It's mentioned in the release notes for
FW 3.03.

However, that said, I don't think it's working right. When I have
CONFIG:VFO IND=No and turn on the NB, it's quite clear from the sound
that the sub RX NB is NOT turning on. When I have the main and sub RX
set to share the main antenna and turn on the NB, I hear the noise
disappear from the main RX side, but it's still there in the sub RX
side.

Can anyone else try this and confirm whether it's working as expected
with CONFIG:VFO IND=No?

In fact you will see the B VFO display A->B ALL for a short time. It
will also turn both NBs.

Re: Sub RX Noise Blanker - 3051

So you're saying that if I have the main RX and sub RX tuned to
different frequencies and want to turn on the NB on both, I have to
hit A->B twice, thereby moving the sub RX to the same frequency as the
main RX, and then retune the sub to the frequency it was at before?
That would be ... awkward.

And if I'm in diversity mode and want to turn on NB on both RX's, I
have to hit NB then A->B??? That doesn't make any sense either.

Re: Sub RX Noise Blanker - 3051

Joe,

I've witnessed the same NB phenomenon with my K3 #192. I have posted about
this on this reflector but got very few answers.
Hopefully someone will find out what's causing this behaviour. I would love
to have a working NB in my subreceiver.
