It feels strange.

That was interesting.  I think I saw the same dead U1253B on eBay when I was looking at prices to see if the used one on Facebook Marketplace (still there...) was reasonable.  Also interesting is that the replacement display is a third party kit.  I could've sworn I saw somewhere that Keysight sold OEM displays as a replaceable part, particularly since that is a current product; I'll have to check their website later.  Another interesting thing is that it's the U1253A/B that get all the attention.  I haven't seen much said about the U1273A/AX or the insulation testers that also had OLED displays.  It's the insulation tester that worries me long term.  Those were recently discontinued and the seven year support period after the discontinuation date is starting to tick down.

Not with a 250MB/s P-P wireless connection and your ISP's UPS in the house keeping your connection up !  ;D

The Pop part of Mom& Pop was here today for a coffee and checked our connection speed ....as just reported and also dropped off a new 3 blade 24V wind gen to go up the hill on our backhaul site as this winter the PV panels have struggled to keep the batteries full which has pissed us off some needing to keep an eye on the bloody things every time we have a session of dull weather......then a few days back it became obvious why, apparently at high altitudes the southern hemisphere still has a lot of fine ash aloft from the big Tonga eruption a few months back.

Anyways, one of these suckers:

Wonder how long it will last 200m ABSL where there are unrestricted views between Aussie and Chile....translation = blows like a real SOB !
Pics to follow when installed.

In that case, all it takes is a stray cow to scratch it's ass on the pole  :-DD

The wind gen site is already up and running with an 8' galv pipe mast bolted to one of the posts on the post and rail around the control cabinet and 6M timber pole but with a vertical helical POS generator that's only good for landfill !

That helical thing has been a real disappointment so it must go and be replaced with something designed in the US of A that might actually work !  :rant:

And so over the last couple of days it was done.  :phew:
Yesterday (Monday) in readiness for the real installation work, the useless helical turbine, its 3 phase controller and wiring was removed and new 2 core tinned marine wiring installed and ~600mm extension to the 1.5" galv pipe mast so to make today's efforts simpler. The weather was closing in and we did most of this in light rain but with barely a breeze, thank heavens !  :phew:
This thing:
Air X Marine wind turbine with 110mph survivability....and it will need it !

The 3 carbon fiber blades are as sharp as one thing hence the need to add an extension to the pole to prevent it from scalping us anytime we needed to work on any part of the installation.
Now blowing 20+kph tonight and already we can see the batteries benefitting from charging after the sun has long gone.
Pop of the Mom&Pop ISP is well pleased as we can both see 25.16V at the batteries from the solar logging whereas just after dark 3hrs back it was 24.42V.
In a few days I'll grab a screenshot of the latest logging which should clearly demonstrate the challenges we've had with keeping this installation fully charged this winter.

Anyways, you've probably seen pics in previous postings so I won't bore you with old ones, just one of the new turbine and a bonus one of the indicator LED's on the radio of the 900mm 11 GHz dish with 900W of solar panels in the background.

Next upgrade is to the DC powered POE 1GB/s switch, of which the current 6 port one is full so no spare ports for local management without unplugging something and a local POE camera is planned to be added.

Study of the attached solar logging demonstrates how the new wind turbine has saved our bacon in the last week or so as 10 days back is last when batteries were fully charged where it shows 41 mins of Float charge and finally today we are again at a Float charge state however the W/hrs of solar charge logging tells the full story of what's going on.

This installation uses ~1600 W/hrs of solar energy/day which of course for 10 days should total ~16000W/hrs when instead only 10900W/hrs of solar has been injected into the batteries with wind doing the rest and keeping the installation up and running.  :phew:
The odd day also shows higher than normal minimums that are a result of the wind turbine contributing more than the overnight quiescent drain.

The wind turbine for site #2 has also arrived and we'll do that install when we get a break in the inclement weather.
