I think the PTT off is already built into WSJT-X.  But it was not built into 
hamlib so now it's double-protection.

I did test it and I was able to change bands while transmitting using just 
Hamlib.

Hi Glenn,

One question: Are your considerations theoretical or have you actually found 
that you stay transmitting when you make a such band change? Because I have 
just tried to reproduce this. Result: WSJT-X stopped transmitting immediately 
when I changed the band during transmission.
