KNW TR-751 WSJT Mod
The TR-751 has the AGC fixed to “SLOW” when in ssb mode.
If we want to use this rig on meteor scatter digital modes (WSJT) the AGC is too slow and some reflection may be lost.
It’s very easy to set it permanently in “FAST” mode, like on CW: just disconnect (and isolate) the white wire (pin 1) of J11 connector on the bottom of the rig.
