With it’s TitanSDR, Italy-based company Enablia has a new approach in SDRs: This receiver delivers up to 40 demodulated channels in different HF bands.
Applications are numerous, e.g. checking GMDSS channels in different maritime bands (see above), monitoring many ALE channels at once, control broadcasters with all their parallel frequencies etc.
This paper delivers on 26 pages and with 44 illustrations a detailed hands-on explanation of this new approach. It is enriched with some audio clips. It shows real-world example of receiving brodcast, amateur radio and utility stations. And it assists you in setting up a couple of decoders at once to monitor many channels in parallel.
