Hello Ken, > > I should have asked - is USB 2.0 sufficent for SDR? Perfectly sufficient. Look at the Perseus and the QS1r RF sampling receivers. Both use USB 2.0, and are able to display, point-and-click, and record into a WAV file a span of 2 MHz of band, digitized (after the DDC) with 24 bit resolution. Using a sound card, the bandwidth requirements are much more relaxed, you won't go beyond 192 kHz of band.. > Would I really buy anything by going to the Firewire/i.Link > soundcard - other than spending more money? The only advantage would be that of leaving an USB port free... But if for you the Firewire is more easy to use, a good external sound card (if used with the latest drivers...) is the Behringer FCA-202. Don't know anything about the i.Link, nor about its compatibility with the IEEE-1394 standard 73 Alberto I2PHD
