Bought my FT-902 in 1988, and FT-901 today (at at price of $120.-)

Planning to publish the following mods on my site soon, some have been available
on other sites for some time. But a lot of my mods have been presented in a way I 
don't like where the schematic or text information miss 

1) Block schematic for IF part of the transceiver
2) logarithmic S-meter using MC3356
3) IF frequency information
4) reduced RIT range
5) antenna rewiring
6) Line output amplifier
7) TX- level equalizing for FT-902
8) SSB filter in cw mode
9) Transverter output modifications
10) FT-902 Mode dependent RIT
11) FT902-keying. 
12) Improving  FT-902 speech processor

Cannot give complete details for all mods since most were carried out in 1988
