Hi Don,

The k1 4 band is a vy nice radio - i wish the kx3 has ist form factor (but i
know it is only possible by shrinking our fingertips.

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.
