glfer

program for reception and transmission of QRSS/DFCW signals

Glfer is composed of two main parts: a spectrogram window, where you can see the spectrum of the received signal vs. time and transmission functions, to emit cw characters at a slow but precisely controlled speed, using the QRSS (slow CW) or DFCW (Dual Frequency CW) modes.
