While I am not to first to test this, I am happy to have MY first success with Multipsk, an SDR, and RS ID. Patrick should get a Nobel prize for this, it will make digital mode hunting even better .
It works as advertised. Phil KA1GMN and I did a test. I placed my received on 18090 and Phil sent an RS ID (he was CQing) on 18100 As you will see in http://www.obriensweb.com/phil.jpg , the wider (48 khz wide) Multipsk detected his RS ID , sent an audible "beep" to my PC , and alerted me visually that an RS ID was detected up 10 kHz. This could be very useful for bands like 20M where there is quite a wide range of frequencies for the digital modes (14065 to 14109). I finally did this by stealing my son's PC , just to test. My Pentium 2.3 single core CPU would not handle the load, but my son's Pentium single core 2.7 CPU did so, easily. See http://www.obriensweb.com/multipsksystem.jpg for system info. Thank you Patrick. At the moment, Multipsk is the only application that lets you feed wide I/Q data to it so that you can decode signals wider than the normal audio bandwidth, Andy K3UK
