Looking at Things: Elad FDM-S3 [beta]

The new FDM-S3. Made in Italy, by ELAD.
19.7 MHz alias-free for receiving, recording and playing

As seen from now, ELAD’s FDM-S3 is still to come. It features a 16 bit SDR with up to 24 MHz bandwidth (19.7 MHz alias-free) for receiving, recording and playback. It will become the great brother of the renowned FDM-S2 of also 16 bit, but with just 5 MHz alias-free bandwidth which was State-of-the-Art when this radio hit the market. Still, this remarkable FDM-S2 sets the standard in its price class.

The file format of the S3 is the same as with the S2, so Simon Brown’s software SDRC V3 works on S3 files also (see screenshot at the bottom). This opens V3’s File Analyzer plus up to 24 demodulators when playbacking files. SDRC V3 will support also live reception when the radio will be more widely available.

Simon Brown’s software SDRC V3 is reading FDM-S3’s files also.
The FDM-S3 cover the whole FM band. Here shown with receiving six stations in parallel, including demodulation and RDS deocding. The lower half of the the spectrogram shows the performance without pre-amplifier, the upper part with pre-amplifier switched in.
