Japanese limits
DISABLE
When this setting is enabled, QMX will refuse to go into transmit mode if the specified synthesis
frequency is outside the Japanese band limits as specified in the JARL bandplans document
https://www.jarl.org/English/6_Band_Plan/JapaneseAmateurBandplans20200421.pdf. This setting
is useful for Japanese license regulations compliance.
CAT timeout
ENABLE
When this setting is enabled, which it is by default, there is a timeout on Transmit; if the timeout
elapses and QMX does not receive a CAT command requesting it to switch back to Receive, then
it will automatically switch back to Receive. This feature needs to be disabled if using VOX.
CAT timeout (s)
120
The duration of the CAT command timeout (see above), in seconds.
PTT as Serial 3
NO
Enabling this parameter changes the behaviour of the 3.5mm PTT jack. This jack becomes an
additional serial port. This requires a HARDWARE change to remove and bypass the transistors
driving the PTT signals. The port is then a 3.3V logic (5V logic tolerant) serial port with
configurable baud rate.
IQ Mode
DISABLE
When IQ mode is enabled, the raw I and Q channels from the ADC are fed to the USB soundcard
directly, without any demodulation. This is suitable for people wishing to experiment with using
QMX as an SDR front end, with PC SDR software to demodulate I and Q channels.
IQ Mode is not suitable for use with WSJT-X and other Digi mode programs.
