DownloadEchoes it's a radio spectral analysis software for SDR devices, designed for meteor scattering purposes.
The older releases supported only RTL-SDR devices. They are very cheap SDR based on DVB-T TV tuner dongles based on Realtek's
RTL2832U chipset. Starting from 0.50 Echoes embeds SoapySDR allowing the support of many other SDRs.
Echoes doesn't demodulate neither decode any human-made signal. Its main goal is to analyze and record the total power of natural signals and generate screenshots and tabular data (CSV,) output in presence of particular peaks in a selected narrow range of frequencies. Since there is no demodulation, there is no provision for audio listening, except for a notify sound when an event has been recorded.
Features
- Captures waterfall spectra as PNG screenshots and statistics data files.
- Multiple instances can manage separate dongles plugged in the same computer
- Three operating modes: continuos (records data only), periodic (captures data and screenshot every X seconds) and automatic (record data and screeshot each time a customizable (S-N) treshold is exceeded)
- The same dongle can be shared by different instances simultaneously via UDP
- binary Installers ready for Windows7++ (64bit) and RPM / DEB / xz for Linux
- It can run headless, recording text dumps and statistic data only
- Daily archiving of captured shots and data in sqlite3 database file
- The collected data can be extracted and analyzed thru the Ebrow utility
- Still through Ebrow, the counts can be packed and sent to RMOB server.

So far so good. easy to use. However, lack of practical examples makes me wonder where to ask for help :)
