I am still very much in Newbie mode, but have the QRS software working and will run from 9 -11PM EDT on 476.2kHz. I can alter time and freq for any good reason. Hopefully I have the frequency correct within a couple of Hz. I have Spectran running on the 15.625kHz I.F. of my 3586C and am eager to listen for QRSS anywhere in the band.
