Re: Looks like ANDE is coming down!
Ron, same here. During my best AM pass, I only decoded one packet!
Warming and cooling is expected. The warming we have been seeing is mostly due to ANDE's orbit precessing into a full sun phase that also happened to coincide with the winter solstice.
That peak for ANDE just passed yesterday, so it will be cooling. (Eclipses are getting longer). It will be interesting to see how much of the warming was due to the sun angles and if any of it yet is due to friction..
See the trends on the "side A telemetry" link on the ANDE web page:

ANDE's at 118 sm, according to the keps. Mighty low.
The onboard temperature started to dip. Unexpected.
I'll be off island starting Dec 27. The remaining passes are poor for me. Sorry Henk and Bob, I don't make it for the certificate.
I did
hear audio, but could not decode the S3 signal on a 24 degree pass with a 3 el Arrow.
