What happened?

DEXP on/off button and slider do not seem to respond to DEXP level or turn it off. It appears to be set to ON with some level of DEXP selected. Unable to turn it off or change level. Verified it works correctly in SmartSDR v4.2.20.

What did you expect?

Ability to turn off and adjust DEXP. Expected same functionally as SmartSDR.

Steps to reproduce

1. Set up second slice receiver on alternate antenna set to same frequency as TX slice (both slices on SSB).
2. Enable FDX.
3. Monitor audio using headphones plugged into radio headphone jack.
4. Turn off DEXP and MOX on. Background noise should be audible. It is not.
5. Proper DEXP setting should be turned on and level set at the point just beyond the disappearance of background noise. Unable to set using this method since DEXP appears to always be enabled and slider has no effect.
