I have the same problem with K3 #969.

All was fine when I first installed the KRX3, right after it was released. However, when I installed the new K3SYNA boards the audio problem for the sub receiver manifested itself.

I have verified that the settings and filters for the sub receiver are the same as the main receiver. Note that the RF signal between the two receivers is identical, as shown on the K3 S-meter and the P3 display.

Recently I noted the latest KRX3 installation manual (downloaded from electraft.com) has a section entitled "Checking and Modifying Resistor R91 and DAC Input Circuits”. The manual I followed when installing my KRX3 only had a similar section entitled “Checking and Modifying Resister R91”.

The latest KRX3 installation manual states that the missing step involves cutting two traces on the main board board to the left of R91, with the justification that “This modification ensures the digital-to-analog converters (DACs) always receive the proper signal levels. It has been incorporated into all later K3s.”

Could this be the cause of my Low sub receiver volume problems? Should I cut these traces now?

Thanks and 73!

Re: K3s Low sub receiver volume

Tom,

Yes, cut those traces if it has not already been done.\
That may or may not solve your problem.

Also tried the front panel earphone jack, with the same results as the rear panel jack.

Re: K3s Low sub receiver volume

Checked that: antenna is the same for both receivers. And, the RF signal level is the same for both: its the AF gain that has the difficulty.

Re: K3s Low sub receiver volume

I use the sub on diversity and dual monitoring. I have my front panel knobs set to adjust levels between the two receivers. If using diversity, then B Set is required to set the correct antenna as the wrong antenna can create low volume. You might want to review your settings and possibly go back to originals if you have saved them when you first backed up. You can always come back to current. I save regularly regardless, as I do mess up settings when going through the menus. Perhaps an aging issue. :-)

Re: K3s Low sub receiver volume

In reply to this post by Thomas Doligalski

CONFIG: L-MIX-R set to A b?

CONFIG:SPKRS 2? Anything plugged into speaker jack? Mono plug or stereo?

Re: K3s Low sub receiver volume

L-MIX-R set to A b
SPKRS set to 1. I don’t use an external speaker. I use a set of stereo headphones, plugged into the rear (have also tried a different set of headphones, plugged into the front).

Other settings include:
KRX3 set to Ant=Atu
SUB AF nor

Thanks!

Re: K3s Low sub receiver volume

Well that was interesting.

I went back into the config menu and rotated the L-MIX-R entry through all of its settings. Kinda neat. When I finished I set it back to A b.

Wonder of wonder, everything seems to work like it should again! I’ve saved the configuration file now!

Thanks to al who over several years tried to help me get through this!
