the 1000MP receiver intermod performance about 20 dB worse."

Huh, t-w-e-n-t-y dB???

For those interested, I've posted W2VJN's explanation of the mod on my Web 
site at http://www.albany.net/~bg/Yaesu/MPInrad.htm - George also explains 
it in the Inrad brochure.

It is my understanding that in conditions of very strong signals, the "IPO" 
switch or attenuator should be used to back off the gain and neutralize the 
action of the 70Mhz if amp that is added by the mod.  This will bring the 
IMD strong signal performance to the same level as an unmodified MP.  As 
K6SE reported, it's in weak signal conditions that the mod really shines.
