Assuming I can solder it without killing it, I will be adding PPS to the DCD pin according to these instructions. http://www.satsignal.eu/ntp/Sure-GPS.htm Before I even do that, I'm going to test it with the serial output going into a Prolific based serial - USB converter. I want to see if it exhibits the "drifting" behavior that I've been seeing on my Globalsat BU-353. Once that's done, I hope to add PPS. I've been told by David Taylor that I should be able to get 400 us offsets through the serial - USB converter with PPS but haven't had a chance to test anything yet.

I get about 300 emails per day from alternate energy mailing lists and such. I don't always see new messages very quickly.
