In short, it's a rechargeable thing that sits in it's docking station during the day. At night it rolls out along a row of panels and brushes them all off, then moves from row to row and eventually returns to its docking station. That's a very slick system, but I think it could be a lot

Re: [AFMUG] Temperature compensation at high temps

They show an operating temp up to 50C. It’s hard to tell with the Engrish translation, but since that sentence is in the context of the temperature compensation chart down below, maybe they just don’t want us to go any lower than 53V. In other words, I was reading it this morning as “disable

[AFMUG] Temperature compensation at high temps

>From a VRLA battery’s operation manual: "If ambient temperature below 5℃ or above 40℃, temperature compensate is no longer go on." Hopefully we never get that room up to 40C/105F, but why would we turn temperature compensation off at that temperature? -- AF mailing list AF@af.afmug.com

Re: [AFMUG] Are you reliant on searching?

A few weeks ago the Windows search box was broken for me, but I was in the middle of something where I couldn't restart my computer. That was the first time I'd used the Start Menu to open applications in 4 or 5 years. I only use Start to find the "shutdown" button. Yes, it's faster to search

Re: [AFMUG] "Low pass" attenuator

In my imagination I picture something with microsecond response time that only affects the signal from the stronger ONT. If signal is stronger than -15 then reduce it by 5dB. Maybe some kind of opto-electronic switch that directs light through two equal length paths. One path has the

Re: [AFMUG] "Low pass" attenuator

Exactly. We were testing a different brand of XGS-PON transceiver. It works fine, except clients stronger than about -14 don't connect. Our current brand alarms at -10, but functions as high as -7, so our design assumes -10 as a cutoff. We can go around and pad the hot ONT's, but it would be

Re: [AFMUG] This thing on?

So the real news article was about floating artic ice being gone, and they say 80-85% of it is gone now. So they missed on the exact timing, but most of it is gone. The bit about the “end of humanity” was a clickbait headline someone attached to that. The kid thought a clickbait headline
