- glfer is a program for reception and transmission of QRSS/DFCW
signals. It is composed of two main parts: the spectrogram window, where you can see the spectrum of the received signal vs. time
the transmission functions, to emit cw
characters at a slow but precisely controlled speed, using the QRSS (slow CW
) or DFCW
(Dual Frequency CW
- Multiplatoform freeware DSP software. Linrad has its origin in software that was developed for 144 MHz EME CW
but it is quite general and should be seen more like a kit for designing a receiver that a receiver for some particular usage.
It can be used as a CW
receiver with a small time delay and a fast waterfall graph. A dsp for conventional receiver to imporve signals readability, a spectrum analyzer.
