AND .. there is the problem of transmitting a LEGAL ID by your D700.  When 
used as a "one way" cross band repeater (listening on 440 and transmitting 
on 2 meters) your you can ID 'normally' with your HT and it will be 
transmitted by your D700 .. BUT .. when used in a "two-way" mode there is no 
way for you to ID when your radio receives 2 meter from the digi (or 
repeater) and transmits on 440. That 440 transmission will not have a legal 
ID.
