Sub Band Speakers on 15M Band

[Irwin KD3TB]

With the K3 in Split mode and Sub turned on, on 20 Meters I can hear the
Main and sub band in separate headset speakers, but cannot  on 15 Meters

 

Is there a Config/Menu function that has to be set by band?

 

Thanks,

Hi Irwin,

The answer to your question is no but I think you're on the right track. There are several items that are band selectable that could affect the audio output of your SUB RX on 15 meters. The most likely of these is your antenna selection. If you accidentally selected ANT 2 or AUX RX for your SUB RX on 15 meters and if you don't have anything connected to those inputs then you would indeed hear no audio on your right channel speaker when on 15 meters.

Irwin,

Do you have the Main tuned to 20 meters and the SubRX tuned to 15 meters?
If so, the 20 meter Low Pass Filter is selected and will cut the 15
meter signal to almost nothing.
The same thing can happen on other band combinations.  To avoid that
problem, either set the SubRX to a band lower than the MainRX.
Or, use the AUX antenna input for the SubRX (that avoids the LPF).
