Hi Joe, > Another problem is the files are probably low bandwidth, 3-4 KHz audio > files. And almost certainly uncalibrated. Well, low bandwidth makes them useless, but there is a lot of wideband hardware out there now. SDR_14, SDR-IQ, SDR-1000, softrock and many more. People should have files at 48 kHz bandwidth at least even though they might hesitate to upload such files to the Internet because of the size.

I have no idea, but they sell Delta 88 (or whatever the name is and that is already 8 channels) > The HPSDR Mercury board should be interesting when it becomes > available (http://hpsdr.org/wiki/index.php?title=MERCURY). I think we will have to wait for a couple of generations. All the decimation steps have to be synchronized, and the bandwidth will become pretty small if one goes for 4 or more channels. I would like a similar design, but designed for multichannel from start and with much more bandwidth. 73 Leif ############################################################# This message is sent to you because you are subscribed to the mailing list <linrad@antennspecialisten.se>.
