Chip K7JA told me that for best CW use the 600HZ filter and notch/audio filter for best results.? Chip is a top notch CW Op and was VP of Yaesu NA at the time.
He told me to stay away from the Yaesu GEN Mod.? K4DPK made one work on GEN TX but he told me years later it was cut and try to get GEN TX,?
I made a booklet of the FOX Tango newsletter? ft-980 mods in the 1983 and 1984 mods.? I gave Wald N4PL a copy.
The 980 on my main operating table hears well on 10.?
