- Fast, high resolution time
-frequency analyzer with FFT display for time
and frequency variant signal
- Voice Shaper is a freeware windows speech pre-processor for SSB transceivers. It receives the voice signal
from the microphone connected to the soundcard, and sends the processed audio back to the soundcard in real time

- EchoFilter uses the soundcard of a PC to process income audio signal
s in real-time
. The narrow filter bandwidth allow the extraction signal
s and sounds from the audio signal
that may normally be close to inaudible.
It is intended for radio HAMS, hobbyists, researchers, scientists and students in the DSP field.
- glfer is a program for reception and transmission of QRSS/DFCW signal
s. It is composed of two main parts: the spectrogram window, where you can see the spectrum of the received signal
the transmission functions, to emit cw characters at a slow but precisely controlled speed, using the QRSS (slow CW) or DFCW (Dual Frequency CW) modes
- 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 signal
s readability, a spectrum analyzer.
