**MODS FOR 9600 BAUDS ON YAESU FT-2400H**
Some weeks ago I wrote a letter to YAESU-Japan requesting information about
the necessary mods to work on 9k6 with the FT-2400H.I received a letter from
Yaesu-Japan answering to my question.This is what they wrote to me:

"The FT-2400H can be modified for higher band rate data communications.I have
enclosed a diagram showing the attack points for 9600 band data,as advised 
from a service engineer for the FT-2400H,HOWEVER,THIS HAS NOT BEEN TESTED FOR
PERFORMANCE...."

So..mods are on your own risk.Good luck and enjoy TONY (EA1DRI)
And this are the "attack points" that they enclosed to me:
