I wonder why ELECRAFT has choosen a different design approach to mute the K3 IF signal to the P3:
K3 internal keying (by paddel jack or by M1-M8):
IF signal is fully muted (P3 display freezed)
--> allows no monitoring of spectrum and transmitted signal while keying
--> P3 diplay does not support QSK
K3 external keying (by key jack):
IF signal is muted only during dots&dashes
--> allows monitoring of spectrum and transmitted signal while keying
--> P3 diplay does support QSK (which I do appreciate).
