[Yaesu] FRG-100/FT-840 Receive MOD

Has anyone done the MW band receive sensitivity improvement mod on the
FRG-100? See above link. I'm presuming that the FRG-100 and FT-840 circuitry
is similar to an extent because both entered the market at the same time in
the early 1990's. I want to do a similar mod to my FT-840 for improved MW
and especially LW receive sensitivity.
