I've read on the D710 list that a manufacturing change has been made on 
the board around the IF filters apparently to provide DC blocking caps 
to remove the bias on the filters which was causing the failures.  
That's actually the main reason that I had been able to resist the 
temptation to move to a D700/D710 until now.

I was hoping the FTM-350 would be better, but an answer has been 
received from their support group indicating that the ability to 
transmit from computer control cannot be done due to hardware 
limitations and a bunch of the other "defects" cannot be fixed due to 
restricted memory inside the unit.  Another first-rev radio bites the 
dust for my primary usage desires.

PS.  I'll soon be the new owner of D700 and will do some 
command-in-packet experimentation and provide workarounds in a custom 
Kwd(D700) port support, I hope.
