Blocking means the S/N ratio or gain changes some detectable 
amount when a single strong signal comes on, IM means spurious 
responses or signals are generated that are not really there.

I'll take a little desense (blocking) over IM problems any day of the 
week, although I'd rather have neither! 

While I haven't looked at a MK V yet, the test reports look 
suspiciously like the FT1000(D) measurements I have made before 
doing a noise blanker mod. I'm only guessing but perhaps the 
same noise blanker flaws were brought forward to the FT1000MP 
MK V, rather than learning from past mistakes.  

Another problem not always reflected in these tests are spurious 
responses not related to IM products caused by synthesizer 
artifacts. One JRC transceiver with exceptional IM3 and blocking 
performance has so many spurious responses it is nearly useless 
for weak signal work on congested bands.
