19.5 HOW TO CONNECT AN EXTERNAL KEYER USING THE FSK/KEY INPUT ON
THE ACCESSORY CONNECTOR
In CW mode, the FSK/Key input on the rear panel accessory connector (pin 4) can be used as a straight
key input. This is useful if you wish to attach an external keyer, such as a K1EL WinKeyer, microHAM
microKEYER, or another contest-oriented interface. This input is always active and is not affected by
the FLEX-6000 internal keyer settings. It’s therefore possible to use both the external keyer, and the
internal keyer at the same time.
