FAMIS 31096

No major changes this week, but the FSS RefCav trans TPD jumps I first noticed last week are still happening, so I continued my investigation into their cause.

Thinking these jumps were being caused by some frequency feedback from the IMC or the arms since they don't seem to line up with anything else in the PSL, I trended some IMC signals looking for similar behavior. Sure enough, several IMC electronics signals have trends that follow the jumps in power seen on the FSS TPD, including IMC-F. See final screenshot for a before/after comparison of these signals around last Tuesday's maintenance period when this change began. Also, in looking at more locking examples, I can say that the jumps start occurring towards the end of 'LOCKING_ALS' or during 'FIND_IR' states in main locking and persist until the next lockloss. Again, not sure that anything really needs to be done about this as it hasn't been causing problems that we've noticed so far, but it would be interesting to know why this change started and if it goes away for some reason, so I'll continue to keep an eye on it.
