Settings For Com Port Generated Ptt Keying - microHAM micro KEYER Quick Start Manual

Settings for COM port generated PTT keying

These settings are applied when the transceiver is keyed by a computer generated PTT signal
(on a virtual serial port) or by WinKey PTT.
A - This setting disconnects computer generated audio from the transceiver and connects the
station microphone to the radio. This setting can be used for CW or FSK mode and is useless
for SSB or digital mode operation.
B - This setting routes audio from the computer sound card output to the transceiver rear audio
input and connects the station microphone to the sound card mic input. This setting is useful
for digital mode operation when the computer generates a PTT keying signal on a COM port.
This is the preferred setting for digital mode operation.
C - This setting routes audio from the computer sound card output to the transceiver
microphone input and connects the station microphone to the sound card mic input. This
setting is useful for SSB message ("voice keyer") playback and recording with software capable
of providing a PTT signal on a serial port. This is the preferred setting for SSB contest
operation using WriteLog or the N1MM Free Contest Logger.
