[HCDX] Perseus Software Defined Radio: First Audio Files
Hallo - in the next few weeks, "Perseus" will hit the receiver market. It is
a software defined radio, priced competetively at about 800 Euro. It will
show a band of about 500 kHz at real time in which one can tune by simple
mous clicking. The whole band (or parts of it) can be recorded on hard disk
for later time-shifted reception as "live" with all bells and whistles at
hand (e.g. notch, passband tuning, AM synchro detection, and tuneable
bandwidth).
Unlike former receivers of its kind, Perseus had been designed by Nico
Palermo also bearing the high demands of a shortwave receiver (it covers 10
kHz to 40 MHz in steps down to 1 Hz) in mind. Several bandpass filter at RF
stage and a careful design result in a wide dynamic range (+100 dB), and
high IP3 (+33 dBm).
As journalist, I was among the happy few beta testers of hardware and
software. Looking back towards nearly 40 years of shortwave listening and
receiver testing, I never encoutered such a high level of intelligibility
and performance.
I recorded some audio clips with Perseus and its first beta software which
even didn't incorporated synchro detection (thus recordings mainly were made
via ECSS) or noise filter/blanker. You can listen to them on the websites of
Perseus' dealer, namely SSB Electronic. Please unterstand that the access
had been programmed with flash, so not to take this word too literally:
uploading may take some time. This part of their site still is somewhat
under construction:
