Thanks Burns,

       I knew there were issues, but the carrier only was something new which I why I reached out. It appeared at the correct time for AOS, increased in signal strength at TCA and was gone at LOS so I am pretty confident it was AO-95.

My last pass it never woke up, we shall see how long it is before it is permanently silent.

AO-95 started resetting every orbit a week or 2 ago and has been getting quickly worse. Now it resets several times per orbit and does not always start up as soon as it hits the sun like it did initially.

If you download the data, you can see that about the time it started resetting, the battery voltage took a sharp drop. My guess is that one of the series battery pairs started holding less and less charge (causing it to reset when it was in eclipse) and then shortly thereafter one of the batteries in the pair shorted, bringing the maximum voltage down. It may be that the other two (pairs) are ok.

It is interesting that you heard a carrier with nothing else. If it is operating at all, I would expect 5 seconds of telemetry alone and then 5 seconds of voice ID with telemetry under it.
