It looks like it took three hours for the effects of the rollover glitch to mostly settle out. BTW, if you only use Lady Heather with a Thunderbolt, you can force the rollover state from the command line or heather.cfg file by using the /ro command line option. If you do that you won't have invalid dates for the 10-15 seconds it takes for Heather's automatic rollover corrector to kick in. If you have /ro in the heather.cfg file and wish to temporarily cancel it to play with another receiver that does not have a rollover issue, you can start Heather with /ro=0

Out of curiosity, have you done anything particular to keep the oscillator so stable? Mine seems a bit more noisy: if I set my display to 2ppt/div as you have, things are off the scale. I typically see a span of ~1000-1500 ppt with an RMS of ~100-200 ppt. To be fair, I'm just using an old Cisco power supply from the eBay vendor that sold me the Thunderbolt, and my Thunderbolt is sitting on a block of foam on the floor in a room at the apartment with no particular temperature control.
