Hi Bob,
    thanks for your reply.
I see that both the ANT TUNER connector and the LINEAR AMP connector 
have two pins labeled "TXD" and "RXD" so I assume I have to 
investigate those. I'll try this, I would have preferred some other 
way (no reverse-engineering by me HI :) ) but I'll see what I can 
find, and in the case I discover something useful I'll let the list 
know about it.

Thanks,
Fabio IZ4AFW
