microHAM microKEYER Manual page 34

microKEYER 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 PTT) 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 or LNA PTT timing can be specified for the PA PTT
output. Checking either box enables the PA PTT.
PTT Lead can be specified in 10 millisecond increments.
Minimum lead is 0 ms, maximum delay is 2500 ms.
PTT tail specifies the length of time the PTT will remain closed
following the last CW character. WinKey has a minimum tail of one word space (6 elements). PTT
tail applies an additional delay that can be set for a "constant" 10 to 2500 milliseconds in 10 ms
steps or an additional one word space (12 elements total), 1.33 word space (14 elements), 1.66
word space (16 elements) or two word spaces (18 elements).
Additional functions can be associated with the footswitch (or hand mic PTT). microKEYER 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 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 resume only after the application releases PTT.
