[Jim, Sebastien]

This week, we've seen the gain of L4C-H2 changing randomly, from nominal gain to a factor of 2 lower.

We tried to chase down this issue without success (see aLOG #8632 and 8666). Everytime we tried something, it magically resolved by itself, and there were no way to reproduced it.

After it happened again today, we might have found the issue though: the in-air cable at the feedthrough felt a little "squishy" and loose. Jim unplugged it and readjusted everything. It feels much better now, and the issue is once again gone.

According to what we saw before, we're pretty confident that was it. If it wasn't, let's keep in mind to start looking at the feedthrough when it happens again.
