SDRuno User Manual
9.1 How SDRuno implements CAT
CAT has been designed in SDRuno so that the application can act as a controlled device and a controlling
one at the same time. More precisely, each VRX can be seen as a separate radio on a different com port
while at the same time it can control a physical external device via Omnirig.
For CAT radio emulation we chose a sub-set of the extensive Kenwood command set.
The following VRX parameters can be set and read:
-
VFO A Frequency
-
VFO B Frequency
-
Active VFO (A
– B)
-
RX Mode
-
AF level
-
Squelch level
-
S-meter (read only)
Also several commands are implemented in a dummy way just to make some controlling programs happy
(HRD for example).
9.2 VRX CAT parameters
VRX CAT parameters are accessible here: RX Control->SETT.->CAT.
9.2.1
COM DEVICE
This combo box allows you to select / enter the serial communication device. It is possibly to choose
among COM1 -> COM20 using the drop-down list. If the desired device has a name that it is not listed,
enter it directly as follows:
-
select the text inside the control (double click on the text)
-
enter the device name by the keyboard
-
press the Enter key on the keyboard
Default: COM10
9.2.2
BAUD RATE
This combo box allows you to select the speed for the serial device. This setting must match that of the
controlling program, the hig
her the better. It is relevant only if the emulated virtual port has the “emulated
baud rate” option enabled, otherwise it can be ignored.
9.2.3
RX MODE CTRL
This option let you to choose if the controlling program can set the VRX RX mode.
Default: enabled
