Yeah, there was much talk on the Flex Radio reflector (which is mostly silent these days) about training your radio's internal oscillator with the 1 PPS / 10 PPS sync pulses from a GPS receiver. I never was that the into the process even though I've had 3 of their radios.

This will keep a 10MC reference in my shack no matter what happens to NIST or the inability to set my transceiver as close as possible to a very tight standard.
