That would be neat provided we can route Audio out via Merc and mic in via 
Pen
or some other hardware or software arrangment so we are not swopping or 
duplicating headsets etc.

Looks like the LT5517 should cover up to 70cm. A three band board would be 
good  2 and 70  populated
with a spare for 4mtrs for EU and 220Mhz for US.

On the face of it  though the Zero IF looks to require a more complex LO. 
With a PEN/Merc digitising IF, three high performace
fixed LO's would likely suffice.
