Font Selection
Before you start using fldigi you need to
select the font that you will need to select the font that will be used
in both the receive and transmit text windows. From the Menu Configure/Defaults select the menu item Fonts. A font selector
dialog will open and you can select both the font type and size from
the this dialog.
Rig Control Configuration
Now pull down the
Configure/Defaults menu and select the submenu
Rig ctrl. That will open up the rig control dialog tab on the main configuration dialog:

|
RigCAT Configuration |
You will need to specify how your PTT will be triggered by the program
including no ptt (none). None would be appropriate if you are
using the rigs VOX or an outboard sound card interface such as the
SignalLink SL-1+ which produces its own VOX type of PTT.
You can use a serial port for control with the RTS and DTR pins configured for you particular interface.
The program allows you to use RTS, DTR or BOTH for the PTT signal.
The default is +V to enable the PTT line. If your rig needs
0 V for the PTT enable, you can select the
PTT reverse option. The
option
DTR=+V will cause the DTR to remain at +12 v at all times and the
RTS should be selected as the PTT toggle. This is compatible with the
G3VGR
interface. If you
use the RTS or DTR line on a serial port you can select TTY and fill in
the port name as "/dev/ttyS0" for example. Fldigi also recognizes
the serial line naming convention used by MSDOS, COM1 ... COM4.
If you hold the mouse cursor over the entry widget for the serial
port you will see a hint that specifies all of the discovered serial
ports on your computer, including the USB serial ports. The one
shown above is for a rigCAT "rig.xml" file. The rigCAT PTT
command is being used for the PTT signal and the DTR pin on the serial
port is being held high to power the CI-V interface. The rig.xml
file also specifies the DTR condition so in this case you would not
have needed to check that item or specify the port.
If you have hamlib installed and your transceiver accepts a PTT
command string you can choose configure your rig for the hamlib library interface. Select the tab
Hamlib.
You may also use either RigCAT or Memmap rig control.
RigCAT requires you to use either a preconfigured rig.xml file
associated with your transceiver or to write your own based on an
existing file. If you have either a Kachina or Argonaut and are
using the CAT program from W1HKJ you can select Memmap. The three
sub tabs look like:
The Rig Control can be left blank or use can select Memmap, Hamlib or
RigCAT. If using Hamlib the Rig, Port and Baud Rate entries
become active after checking the "use Hamlib" box. The pull down
selector for Rig: is
populated by the hamlib library. Select your rig from the list if
you are using hamlib. You must specify the serial port that
hamlib will find the transceiver on in the Device field. This
must be a fully qualified device name as "/dev/ttyS1" for example.
If you hold the mouse cursor over the entry widget for the serial
port you will see a hint that specifies all of the discovered serial
ports on your computer, including the USB serial ports. You also
must select the baud rate that your transceiver
interface is set for.
