EantG went down at 05:21:59 UTC. Log file on the ap24eth again mentions "extensive data loss".  EantH  and EantI (sodar) stayed up.

We power cycled the antenna which brought it back.  We also fetched the pocketecs and usb stick from profile, downwind1 and pressure1.

I'm not sure that changing the frequency, as was done earlier, changes anything. After changing the frequency, the Etherants still indicated that they are using channel #1.

Will now try setting the  disconnect-timeout parameter to 15 seconds (the maximum allowed value). The default is 3 seconds.  Will also increase the on-fail-retry-time to 1/2 second
