Oh boy, and here I just bought a used dual band mobile on the cheap  
(no transmit) to take care of the birdy problem.

Do you have any idea why the birdy would show up on a different  
radio?  Could it be a matter of a lack of shielding?  It just doesn't  
make any sense to me why a different rig would get that interference  
on receive, and even when using a different antenna.

Others have suggested using a preamp on 440, and turning off the  
2000's internal preamp and lowering the rf gain, therefore using the  
preamp to get rid of most of the birdy.

But I guess I'll find out for sure when my other rig gets here.
