[HamWAN PSDR] Haystack Site Outage

[Nigel Vander Houwen]

Evening Everybody,

Today Bart and the site owner took another run at getting up to haystack and managed to fight their way up to the site. They managed to get a lot done, and Haystack is in much better shape.

They found some misbehaving equipment that had a huge draw (>400W continuous) on the power system up there, overwhelming the solar generation capacity, draining the batteries, and causing the generator to run more than it should have been needed, and then run out of fuel.
They brought up 40 gallons of fuel that was brought partway up the mountain on the last trip.
Bart replaced the Haystack-S3 modem to see if it would fix an issue we’re seeing with non-symmetric signal strengths. It didn’t resolve the issue, so we’ll revisit that issue again later.
Replaced the RJ45 connector for the Haystack-S3 modem that may have been the cause for the earlier Haystack-S3 outage.

All together, with the misbehaving loads removed from the system, and the generator refueled to get the batteries recharged so it’s not all on solar to bring things back up, things are looking much better.

We’ve powered back online all of the HamWAN equipment at the site, so the sectors and backbone links are all up and operating normally.

I’d like to thank again the folks who made the previous attempt and got the fuel most of the way up the mountain, as well as bart and the site owner for making the run today to finish the job. All the efforts are appreciated, and are paying off in the site being back online.

Nigel

Unfortunately, as of Friday the generator is out of fuel.
