Fellow Time-Tickers,     I'm pleased to report I was, thanks to an anonymous source, locate the software to run the Spirent GSS6100 (and the 4200 as well, if I recall) GPS signal generators. The file collection has been uploaded to KO4BB's site with the name Spirent_GSS.rar     Happy tweaking. -- Bruce Lane, ARS KC7GR kyrrin@bluefeathertech.com "Quando Omni Flunkus Moritati" (Red Green)
