Roland,

Your suspicion about the T/R switch *may* be correct, but before you
make any changes, check the menu for the T-R setting.  The default is 50
ms.  If you are using a small value, the receiver may be unmuting
quickly enough that you actually hear a bit of the residual RF.

I was not able to view your video - OneDrive just keeps 'spinning its
wheels' as if it is loading, but I waited for over 5 minutes (two times)
and it still did not load.

73,
