Yeah, the drift could be Doppler, that definately would explain it. Interestingly there was not a pass over or near over my location at the time, so I had to be getting it via good old HF propagation. I had not listened for this beacon for years (since the last time I worked it Mode A right after launch) and forgot all about it. The last time I heard it the sag was not as pronounced as now.
T!
T!

But the reason I am not wrong is not because I am right, only that I was asking the question of if there was a possibility that the station had entered a different mode. I was not saying it did, only asking for confirmation that the signal went away instead of changing. If you listened a further 12 minutes (even just a couple more minutes) and did not hear an alternating voice and data pattern then you have confirmed it.
