Another First from the UK's First: RFSpace SDR-14

摘要

On initial examination the SDR-14 appears nothing like a conventional radio. There are no knobs, buttons or dials. Actually there are no user controls whatsoever. The only external features on the light-weight 235x27x190mm box are connectors and l.e.d.s. If you have fixed ideas about how h.f. receivers should look and operate, prepare to have your views changed. The SDR-14 really is nothing like a conventional radio. Since the SDR records all the data for the whole 150kHz all signals that were present during the record duration are captured - that's everything between the lower limit and 150kHz higher - in other words 30 5kHz channels on a short wave broadcast band or all of the 40m amateur band with some to spare!
