6400 drifting issues only on 6M

While on 6 Meters I soon start drifting low within 2-3 minutes sometimes less even after doing a calibration this effect only happens on 6 m that we have seen so far, on 10-160 I do not encounter a drift issue, I have had several folks chase my TX signal while working on 6 meters, in both SSB and digital modes.(those are the only two modes i have tried on 6 M) but would assume it happens in all modes. Has anyone else experienced this, running software version 2.2.8.. Power supply voltage is stable, and a Non M model so no knob is being bumped, have even locked mouse scroll options, and why only on 6 meters.

N8SDR opened a HelpDesk ticket. This seems to be other stations drifting, not the radio. The TCXO is stable.0

Tim had me run a test to check the TCXO and it is working as it should. Using the station who reported me drifting, he swapped out radios on his end and we had a 20 minute qso on 6 meters in which there was no drift in frequency. Apparently his KX3 is having thermal drifts on 6 M also note this article in-which another user of a KX3 experienced the same KX3: thermal frequency drift- http://elecraft.365791.n2.nabble.com/KX3-thermal-frequency-drift-td7587010.html , this is not an issue with the 6400, sorry for the confusion.

No apologies necessary. I'm glad you were able to get to the bottom of the issue.1

You will find many 6 meter stations off frequency as well.0
