FLdigi is a computer program intended for Amateur Radio Digital Modes operation using a PC (Personal Computer). Fldigi operates (as does most similar software) in conjunction with a conventional HF SSB radio transceiver, and uses the PC sound card as the main means of input from the radio, and output to the radio. These are audio-frequency signals. The software also controls the radio by means of another connection, typically a serial port.

FLdigi is multi-mode, which means that it is able to operate many popular digital modes without switching programs, so you only have one program to learn. FLdigi includes all the popular modes, such as: CW, DominoEX, HELL, MFSK, MT63, Olivia, PSK, RTTY, THOR, Throb, NBEMS Modes.

            Radio Shack 1/8 “Y” M/F/F cable (1ea)  RS 42-2570 
            Radio Shack  1/8 “M/M” cable (2ea) RS 42-2387
            Strap P1 to match your radio's Microphone. (i.e. RJ45 IC706 page 9, page 10). 
            Set Audio  Level Control full counter-clockwise. 
            Cable RIGblaster to radio and computer, as shown in RIGblaster manual’s hookup diagram i.e.:
            Cable RIGBlasrer-IN to computer speaker OUT
            Cable RIGBlaster-OUT to computer speakers (The RIGblaster interface will allow computer speakers to continue to operate for 
              music etc. Don't use low impedance un-amplified speakers).

           Computer Volume Control:
         Record: select Line-in - set all Volume controls 1/2 from bottom - Balance sliders to middle & EXIT
            Playback: un-mute all    – set all Volume controls 1/2 from bottom - Balance sliders to middle & EXIT
Radio setup: 
           Set all IF Filters to OFF (or as wide as possible)
           Set Audio RF to MAX - Set AF volume not to overdrive signals on the Waterfall Display window
           Set SQL to minimum (CCW)
           Set VFO to: 14.070   
           Set Transmitter output power to 1/2 manufacturer’s rated power output, 45 watts or less is a 
               good operating setup for a 100 watt transmitter.
           Set Mode to USB
           Set Processor to OFF set SWR ON set ALC ON
           Connect antenna (connecting a Dummy Load will give bad ALC reading in Digital setup)
           Adjust Tuner for 1:1 
           Speak into the microphone, adjusting MIC control so that ALC doesn’t occur above the
                 ALC Zone indicator. 
Fldigi Software Program setup:
              Install Fldigi
              Select Configure
                        Operator: Type Callsign, Name, QTH, Ant., Locator 
                        Colors & Fonts = Defaults
                        User Interface UI General = Defaults     
                        Waterfall – Display = Defaults
                        Modems =Defaults
                        Rig Control – Hardware PTT = Use separate Serial Port, Device = COM 1, Use RTS/TDR
                        Sound Card – Audio = Defaults  
                        IDs = Transmit Mode = ID; Transit Mode = RSID 
                        Misc. – Sweet spot = Defaults
                        Contest = Defaults
                        QRZ = Defaults 
            MACROS: right click on a MACRO, type in MACRO info. For ie.:  (CQ - BTU – Signoff)
            Fldigi display:
                Select: Op MODE - PSK  (BPSK31)
                Select: WF Waterfall (FFT – Sig.)
                Select Upper Signal Level (db) = -30
                Select Signal Range (db) = 69
                Select Waterfall scale = X2
                Select Waterfall Drop Speed = Normal
                Select AFC
                Do not Select RSID; must be off for Transmitting mode   
           Left Click on the HamScope Waterfall Display at any TX frequency between 100hz and 2500hz
               of the selected VFO’s frequency. 
           Left Click on Tx  (Transmit) button --Transmission starts. (Don’t use TONE, it doesn’t allow for 
                 a good IMD reading at a receiving station) 
           Adjust RIGblaster Audio Level Control clockwise, stopping as transmitter output power reaches MAX 
               (ie. 45 watts) keep an eye on your ALC so that ALC does not occur. Run with NO ALC
               indicating occurring; any ALC indicating means that it is distorting your TX Signal,
               causing harmonics. The receiving Operator’s HamScope Spectrum analyzer will display
               incorrectly adjusted Transmit signals.
           Left Click on Rx  (Receive) button -- Transmission stops.
           Note: The RIGblaster Audio Level Control is the most precise way to adjust the 
                 Soundcard output voltage into the radio. The Microsoft Volume controls were
                 designed to vary the voltage, through a range of reasonable outputs, for Speakers;
                 They were not designed to be adjusted so precisely as to be reliable set to 
                 5 millivolts for PSK31 operating.
                 The MIC Gain, once set for Phone, should not be readjusted for Digital PSK31; 
                 that would cause operating problems in some Modes like SSTV.
           ALC can remain (on) to control drive limit.
