At least on my PC (Celeron 233 MHz, 64 MB RAM, not a fast machine today, HI) I will start a test in DFCW with three tones by Friday evening. More later. To James 'BMU: we have to define some "standards" and practice. By instance, working with a BW of 84 mHz, probably good for 12 sec dots, Spectran has a window over 24 Hz of band with horizontal display, and more than 50 Hz in vertical display mode. We may decide to use the last 20 or 40 Hz of the band for this kind of transmissions, so one can monitor all the sub-band at a glance; if you see a signal, then you may zoom-in at higher resolution. And to detect if it really is a signal .... wait and watch... then wait .... patience is the virtue of strong men (sorry for the bad English!) 73, Marco IK1ODO Marco Bruno - IK1ODO spin@inrete.it SPIN Electronics - www.spin-it.com
