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: http://www.ssb.de/amateur/simplay/mp3.shtml
