![]() Please read the specification document rigxml to learn more about this new way of building generic rig interface definitions and how they are used with fldigi. fldigi will look for a file in the $HOME/.fldigi/rigs directory for all files with extension ".xml". These contain definitions for the transceiver indicated by the file name, ie: FT-450.xml, IC-756PRO.xml, etc. You can download the appropriate xml files from the xml archives. Place the file in your rigs directory and fldigi will find it. You will need to specify how your PTT will be triggered. This can be using a CAT command, the RTS or DTR pins or none. None would be appropriate if you are using the rig's VOX or an outboard sound card interface such as the SignalLink SL-1+ which produces its own VOX type of PTT. In that case simply leave all of the PTT options unselected. If you are using a transceiver or a rig interface such as CI-V that echos all serial data you check off the "Commands are echoed" box. That will suppress fldigi trying to respond to a command it just sent to the transceiver. You may need to try various values of retries, retry interval, and command interval to achieve consistent rigcat control. Press the Initialize button after setting all of the parameters. If the settings are all correct fldigi should start receiving frequency information from the rig and annunciating them on the rig control frequency display. ![]() Hamlib is a set of standard libraries for interfacing to a large number of transceivers. The hamlib library system consists of a front end which acts on behalf of all rigs and backends which are specific to each rig. The hamlib library is not developed or maintained by the fldigi developers. Select your transceiver from the list of supported units. Then select the serial port and baud rate. If you are familiar with the hamlib library you can send various startup sequences to the rig using the advanced configuration. PTT control can be achieved using CAT commands or via DTR / RTS on the same port as the control comms. You might also need to specifiy whether RTS/CTS flow control is uses (Kenwood rigs use this quite often) or if Xon/Xoff flow control is used. You may need to try various values of retries, retry interval, and command interval to achieve consistent hamlib control. Xml-Rpc allows third party software to control various aspects of fldigi operation including but not limited to rig control. Fldigi's xmlrpc server is always executing. ![]()
