Assuming you don't GPS lock it... How well will two units from the same manufacturer/batch track? I'm assuming they will see roughly the same temperature profile and that you start with them running at the same frequency. Has anybody made a triple oven setup? I'm thinking of a big box with a few holes and a temperature controlled fan. The idea is to let the oven (and electronics) keep itself warm when the ambient temperature gets very cold. I'm picturing an open hill top at night with clear skies so there would be lots of radiation cooling. Of course, with an open hill top, GPS recption would be easy. -- These are my opinions, not necessarily my employer's.
