Thanks all who replied on and off the list.
I guess Yaesu might have forgotten to put a buffer in there to protect the IC. Given the current state of the economy, I guess (at least for now) I will just continue contesting and operating without it. I just have to re-train myself to change the bands on the PC when I change the bands on the rig. Bad CAT, Old dog, new tricks.....it will have to work for me.
Thanks again.

Greg,
I have had that happen twice.... on a 1000mp.
Last time, I replaced the IC with a Max232 device... but the foil vias around that area are getting pretty ratty.
A long time ago, I read somewhere that this was a problem with this series Yaesu.
The rig has been OK after the last fix.
Good luck...
Mike

I have discovered the root cause of my Rig/PC issues in the NAQP. It appears my RS232 CAT connection on the Mark V blew out. UGH! Perhaps some RF in the shack. I don't even own an amplifier and I was running 100W, but that seems to be the only conclusion I can come to as the root cause (unless the rig is just getting old like the rest of us. :) )
The good news is the radio still works great.
