Thanks, Fred.

I switched DIGOUT1 on while on 6m and it remembers to be on, only on 
6m.  My application will be to control an external relay that will 
enable INHIBIT for 6m-eme. As already mentioned, I use BAND0 for this 
on 2m and higher transverter bands, but I do not want INHIBIT for 
normal 6m use, only to sequence my TR relay and Harris 900w 6m PA, 
when using it.  Applying RF drive without a load on the Harris can 
destroy the amp.  One does not want to "hot-switch" the coax relay as 
900w courses thru it!  So you can add another use for DIGOUT!

I am getting close to "first smoke" with the 6m QRO.
