+;*************************************************
+
+; Like HK-SS TowerPro clones, it seems some Multistar 30A boards
+; have a P-channel FET gate noise problem that causes overheating
+; if the P-ch body diode is conducting when the PWM chops on.
+; This happens less often at 8kHz, so, uhh...fixed!
