[Elecraft] Not hearing on the sub receiver

[William Liporace]

I have a K3S that seems to be having an issue hearing on the sub receiver.
Hit A > B to make sure all settings are equal
Tap the SUB button
Turn the volume down on VFO-A
Turn the volume up on VFO-B and there is no Audio

I think I have the issue on everything above 20 meters (17, 15, 12, etc)
It appears it works 20 meters and below. Has anyone seen this?
