Yaesu FM-747 FM unit for FT-840, how to adjust?

Post by W4AJF » Mon Oct 07, 2019 7:38 pm

Hi all, I have an FT-840 and the FM-747 FM unit but audio output (modulation) is low. It does have some trimmers that can be adjusted, does any one one know which if any would control audio output/modulation?

Thanks for any help.
