RF45 has been quiet since I and Evan made an investigation last time (alog 23125).
One thing we didn't do in the PSL room was to wiggle/tap the EOM inductor box and its connectors. Next time it acts up, we should try that. FYI, inductor box is the top part of EOM assembly that accepts the cable from EOM driver, and is connected to the lower part where the crystal sits by now infamous DB15.
