Re: [time-nuts] Thunderbolt GPS rollover
probably the best rocket tracker http://bigredbee.com/blgps_2mhp.htm there are others. depending on acceleration and duration, GPS + APRS tracking can be unreliable. it seems most COS parts fail at over 15Gs acceleration; the ITAR limits come in at 6 feet and/or mach 1. so, additionally fly a simple Morse tracker like this http://bigredbee.com/BeeLine.htm between the two, you will get your rocket back. speaking from experience!!

Re: [time-nuts] Faster than light of a different type
not at all. read the summary, they are playing with group delay. oh and by the way, there is some effect working with cold fusion. we don't know what it is. that's why it's called basic research. if we knew what we were doing it wouldn't be called research one more thing, people need to learn to hit the delete key if they don't like a particular email. get over it.

It fiddles with some definitions in the speed of light restrictions in quantum theory. the reason I am posting here is that it used Rubidium beams. The actual publications may be of interest to those who use such around here. Sadly the actual information is behind a paywall.

Re: [time-nuts] PICTIC II ready-made?
two thumbs up for Radio Shack - they sure have their problems but they are all we have in a lot of places. with the new Velleman and Arduino and Basic Stamp kits, they are clearly trying. they have a ways to go, but I try to vote with my $$$ a little bit.

Re: [time-nuts] Loran transmitters back on the air.
had a sailboat in the 80s and 90s, used a West Marine LORAN receiver and antenna... easily got better than 100' accuracy and repeatability, year after year. we went to the same anchor holes all the time, took angular sights to confirm the LORAN. loved it. never had a GPS until after the turn of the century... 2002 maybe?
