I am using the loop, which worked perfectly until the new firmware update. 
Pulling either of the QSK control cables disables the O2 from transmit 
unless you shut down the keying loop in the menu.  The workaround is to use 
PTT, which I did for the first few days I had the O2 and works fine, 
although I worry that I may not be protecting my vacuum relay as much as I 
did with the TT QSK.
