I looked all over for a manual for my older yaesu ft2400H without any luck from Yaesu or most other places. I did find a few but they wanted a few bucks for the manuals.
I finally found one at this site in a pdf format.
From what I saw at this site theres a good chance for finding what you might be looking for. Good luck.http://www.mods.dk/view.php?ListManuals
