Hi Art,
The Mai 2010 test report by RadCom magazine conducted by Peter Hart, G3SJX
shows top of the line performance.
2-tone dynamic range at 2kHz spacing was measured at 109db and 104db at
500Hz spacing (preamp off, 500Hz bandwidth).
By the way, most radios allow to switch preamps off for better dynamic
range, its not an invention by Yaesu.

I just can't believe Yaesu invented a new DR and IP3 specification -
10kHz offset - almost surely so they could avoid using the ARRL,
Sherwood etc. standard offset of 2kHz, thereby divulging the likely poor
performance at real honest to goodness close signal spacing. Like the
rest of their lineup. Oh. Wait. Yes I can believe it. After all Yaesu is
the inventor of the IPO nonsense.
Give them benefit of the doubt til real data show up. Be interesting to
see the first honest review coming from one of the evaluators using
unobfuscated spacings that can yield comparison to other radios.
