See μH Router Website for specific details and requirements. Simular functionality can be achieved on the Macintosh operating system using 'μH Router' by Kok Chen, W7AY. Keydown sets Pin 16 to +5 volts and keyup sets the voltage to zero.
#Hamlib ic 7800 setup serial
Press the Initialize button to start the serial port.įldigi sets and clears the parallel port pin, PARPORT_CONTROL_INIT, pin 16 on the 25 pin parallel port connector. The program allows you to use RTS, DTR or BOTH for the PTT signal.

You can use a serial port for control with the RTS and DTR pins configured for you particular interface. Then specify whether the h/w uses RTS or DTR and whether a + or - voltage is required to toggle PTT on.

Select the serial port from the list (fldigi will have searched for available ports). You select this operation by checking the "Use serial port PTT". You set this type of control on the first configuration tab for rig control. The simplest rig control is just being able to control the push to talk via an external transistor switch. Jim, W5ZIT, has provided details on building an interface for this type of PTT control. A simple tone detector/filter and transistor switch can be used to generate a PTT signal from this sound card output. Fldigi queries the transceiver 10 times per second to maintain a lock step with the transceiver.įldigi can generate a 1000 Hz tone for the duration of the PTT keydown period. If you change operating mode on the transceiver, that will be annunciated in the respective combobox and fldigi will adjust any internal parameters accordingly. The mode combobox, the bandwidth combobox and the frequency display also annunciate the current transceiver status. Don't forget the decimal point if you are entering a fractional KHz value.
#Hamlib ic 7800 setup manual
Manual entry of frequency can be accomplished by clicking on any digit and then entering the numeric value in KHz. You can also place the mouse cursor on a digit and then use the mouse wheel to roll the frequency up and down. The leading digits will follow suit if a decade rollover occurs. Each digit may be left-clicked to increment in frequency by that digit value, or right clicked to decrement by that digit value. The frequency display is in fact a set of special buttons. The combo box on the right will allow the selection and control of the transceiver bandwidth. The combo box on the left will allow the selection and control of the operating mode of the transceiver. The list is saved when fldigi is shut down. The browser list contains frequency, sideband, modem type and audio frequency. Show active frequencies based on either the entry field to the right or the stations locator, see pskreporter/spotter.Įntry field for active frequencies search, for example "EM." The pick list buttons control selecting, adding and deleting entries in the frequency/mode list.Īdd the current frequency / mode / audio track point to the listĭelete the highlighted entry from the listĭelete all entries from the list (a warning prompt will appear) Pressing the book button a second time will restore the original logging panel. The frequency/mode pick list is displayed when the book button is pressed. The logged frequency value will only be correct for LSB and USB operation.

This frequency value is used with the waterfall audio frequency to compute the logged frequency. If fldigi is being used with an FM transceiver you probably should enter the simplex frequency or the input frequency of a repeater being used.

When no CAT is available the control is simply a convenient way of keeping track of the transceiver USB/LSB suppressed carrier frequency, the mode and the audio tracking point.

Note: The same control is also used for both manual entry of the transceiver frequency or with full CAT control. CAT not enabled, Manual Entry of transceiver frequency
