MicroKEYER II can select the PTT output based on the mode, and optionally frequency, reported by the
transceiver in response to polling by the application (logger) and/or Router. If Router is not able to
read the operating mode from your radio (radio does not have computer control port or does not
report usable mode information), you can select one of four fixed "no radio" modes or one "no
radio" mode with manual (keyboard/keypad) mode selection.
Router recognizes four operating modes for the radio: CW, VOICE, DIGITAL and FSK (RTTY) with three
selections for PTT: CW, Voice and FSK/DIGITAL.
CW: Options are - PTT1 (microphone jack), QSK (no transceiver
PTT, PA PTT has no release delay), Semi Break-in (no
transceiver PTT, PA PTT includes release delay), and
PTT2 (rear panel jack).
VOICE: Options are – PTT1 (microphone jack) and PTT2 (rear
panel jack).
FSK/DIGITAL: Options are – PTT1 (microphone jack), PTT2 (rear
panel jack), and PTT1 & PTT2 (both jacks).
PA PTT: Enables PA PTT
LNA PTT: enables NA PTT
Sound card PTT: Enables automatic PTT when the sound card is producing audio.
CW in VOICE: Enables CW output in Voice modes. Please note, this function must be supported by the
transceiver. CW in Voice always operates without transceiver PTT (Semi Break-in).
Additional functions can be associated with the footswitch (or hand mic PTT). microKEYER II recognizes
when the footswitch is closed (pressed) or open (released) and can manipulate CW, FSK, PTT and audio
routing when the footswtich is closed or opened.
Mute serial CW - if checked, serial CW (DTR or RTS) from an
application program will be muted while the footswitch is
pressed. If Restore serial CW is checked, CW will
resume when the footswitch is released (if it has not
already ended). If Restore serial CW is not checked,
application generated CW will remain suppressed until
the application releases PTT.
Mute serial FSK - if checked, the FSK ports will be blocked
while the footswitch is pressed. If Restore serial FSK is
checked, FSK will resume when the footswitch is
released (if it has not already completed). If Restore
serial FSK is not checked, FSK will remain suppressed
until the application releases PTT.
Restore serial PTT and audio - if checked, application generated serial PTT will be restored and audio
routing will return to the "serial PTT" setting when the footswitch is released. If Restore serial PTT
and audio is not checked, audio will only return after the application releases PTT.
