problems with the SSB modulator. Can anybody
help me?

Hello,

Try this link: "http://hamradio.online.ru/sch_eng.html", in the Documentation directory there is a file named FT-757GX USER MANUAL (eng. 7,3mb, pdf). Try to check it!

i have over 20 years with yeasu products

the problem you have is caused by the switching for the ssb


you will find dry joints and brocken legs etc easily occur with some connectors to the board

removing each board carefully poping out all the white interconnects
and resoldering

will solve this

it is caused by the sibeband offset not switching in
resulting in double sideband suppressed carries a3e???
when in ssb mode as the tx carrier

another thing is xtal drift the referances drift over time

take the xtals out turn them round resolder than retune to the correct freq



more descibe your fault and i can help shed light on it
