Hello  Manualman, 

A couple of folks commented on the lack of activity on this chain lately so thought a 'kick the hornets nest' moment would generate some heat.  I did look up the GPS receivers that have a 10Mhz and 1PPS output, and 100 bucks on Epay gets you a nice one with GPS ant and walwart.  Another site had comments on this unit, and looks pretty good, but one fellow said the 10Mhz output is not exactly 10.  I can't remember the number he had, but I do remember that he said that works out to a 2Hz error at 100GHz....yes giga.  Guess that is close enough, but don't think you get ionosphere reports from it. I am not into all the details and maybe I misread but one commentor said it actually gets a GPS locked reference 10KC signal and multiplies it 1000 times to 10Mhz, and the signal, while a sinewave, does have some jitter issues.  Maybe someone with indepth knowledge can point out a few things to be wary of.
