Re: Sub RX Deaf??

Chris,
First make sure you have your filter configuration set correctly (including offsets, etc). I highly recommend you use the K3 Utility to Configure the Crystal filters. You didn't mention how you set up your K3 as far as antenna input to the sub receiver. I use the BNC connector on the back of the K3. A couple times when I found the sub receiver deaf, it was a matter of "operator error" with one of my big paws "holding" rather than tapping toe RX Antenna button. The net affect of that is switching the input from Main to Aux. A quick push and hold of the RX Antenna button to go back to Main does wonders to fix that issue!!! Also, make sure you have the KRX3 option in the Configuration Menu set correctly (mine is set to Ant-bnc).
Good luck finding the probem

You didn't forget to enable it in the CONFIG menu did you?

Chris,
When I built my K3 years ago, the Sub-Rx didn't work. I found I had
plugged the synthesizer module (KSYN3 at that time) into its socket just
one pin off - very hard to see. Corrected it and never looked back.
Fortunately, no damage to the synthesizer in doing this.
So maybe?

Re: Sub RX Deaf??

Hello Chris,

i just installed the second RX me too.

Same impression during first but the solution was very easy for me, i
had the Config:spkr set to 2 instead of 1 and simply i had not audio
from the second rx.

Changing Config:spkr value from 2 to 1, make the second rx "screams"
correctly :-)

Ah, and look also in the menù config for KRX3 if is activated and you
choose ANT=ATU if you have not installed the dedicate BNC or ANT=BNC if
you have installed the dedicate BNC, remember to connect and antenna to
the BNC in this case.

Re: Sub RX Deaf??

When I installed my KRX3, it was deaf because I had overlooked the step about configuring the bandpass filters.

Correction: I should have said that when I installed my KRX3, it was deaf because I had overlooked the step about configuring the ROOFING filters.
