[Yaesu] FT-990 mods, noise etc

[Ian White, G3SEK]

Please can someone update me about published modifications for the FT-
990, on or off the Internet? (The only ones I know of are the all-band
TX mod and the one to reduce the power level below 10W.)

Also, did the discussion about IF/AF noise in the FT-990 reach any
conclusion? I collected some of that from DejaNews, but wasn't sure if I
saw it all. Somebody mentioned a modification involving a second filter,
late in the 455kHz IF stages...
