Thank you for the info Alberto, the reading I have been doing is not confirmed by your comments - I think I will go with USB 2.0 - those cards seem to be a bit less expensive... BUT the card you suggested is only $79, best price for a FireWire I've seen. Since this Toshiba notebook has the i-Link port rather than Firewire I think I will stay with the USB 2.0 card selection. I have read Firewire and i-Link are the same, just different names for the same protocol.
Firewire has 4 wire and 6 wire plugs - non-powered and powered connections I think the difference is. My Toshiba has only a 4 wire i-Link - I guess I'll just stay with USB to be sure it will work. Thank you again for the info Alberto - and thanks for your GREAT program. 73 de Ken H> K9FV --- In [email protected], "i2phd" <[EMAIL PROTECTED]> wrote: > > --- In [email protected], "sailingto" <sailingto@> wrote: > > Hello Ken, > > > > I should have asked - is USB 2.0 sufficent for SDR? > > Perfectly sufficient.
