Create a radio station for amateur operations. Perform frequency measurement tests or calibrate a sound card to receive a signal. Access a standard HF SSB radio transceiver and control the radio using serial port connections. Work with popular models like FM, AMS, LSB, RTTY, MFSK16, DominoEX, MFSK, Throb, Hell, Olivia, CW, and PSK.
Fldigi is a solution that provides users the means to transform their computer into a radio station. Equipped with digital modes, such as CW, PSK, MFSK, Hell, or Throb, it helps technology enthusiasts to calibrate a sound card to a time signal and do measurements of frequencies.
Aesthetically, it doesn't have a modern UI, with its menus and buttons having a poorly shaped design. Also, the main screen has poor delimited sections that increase the program learning curve. The CPU and memory are low and that is a big plus for users.
Apart from the supported digital modes mentioned in the beginning, Fldigi lets users manage signal, either by Waterfall, or FFT method, and view the spectrogram display of signal strength as well as an oscilloscope representation of the captured raw radio.
More, it has a built-in signal browser, text capturing options, customization options for data logging, and rig controlling capabilities.
To sum things up, Fldigi is a useful program for individuals who are passionate and have a strong knowledge base of managing radio signals.
v4.0 [Mar 29, 2017]
- clock_gettime
- Change np-compat.m4 to provide for conditional
- use of library calls to clock_gettime
- allow for compiling on OS X < 10.12 using
- Xcode 8.xxx
- use ./configure --without-clock_gettime
- spectrum display
- Changed from fft mode to spectrum display paradigm
- spectrum display available independent of digital mode in use.
- spectrum display dialog opens from "View" menu
- removed all code relating to the original fftscan modem
- added new fltk widget, spectrum based on fldigi's
- digiscope widget
- Test Signal Dialog
- Correct IMD range controls
- dxcluster fonts
- fix dxreport font rendition
- add resizable groups to correctly resize tabs
- Spot buffer
- add clear RE buffer after a successfull match
- Winkeyer clones
- added longer time out for character echo.
- RX Text capture
- Fix loss of capture when Rx text scrolls or user's
- mouse clicks off of the target
- PSK s/n imd
- Changed s/n display code to avoid displaying misleading values
- Changed Noise/Offset/IMD test signal generator
- IMD can be specified in dB and signal will correctly emulate
- an over driven transmit signal.- IMD generator modified to
- correctly computer 3rd, 5th, 7th and 9th- harmonics of PSK
- fundamental (15.625 Hertz).
- Removed "--noise" command line parameter
- Added Test Signal Dialog with
- S/N
- IMD
- tx freq offset
- controls
- disabled display of Rx IMD, s/n values if |imd| > |s/n|
- PSK viewer
- Added the following modes to the multi-channel viewer
- PSK31, PSK63, PSK63F, PSK125, PSK250, PSK500
- PSK125R, PSK250R, PSK500R
- QPSK31, QPSK63, QPSK125, QPSK250, QPSK500
