hey! looks like my internet is back up.

damn isp had dorked something and was not getting any dns resolution. then it got intermittent. now it appears to be working wooooohoooo!

gotta run though. my old boss is coming over to do return loss tests on some 10 Ghz feedhorns. who knew that feedhorns can be adjusted? not me.

gotta go turn on the SA and the sweeper to warm up the yigs.

It was a global outage. Level 3 fucked up. Not just you. Half the internet went

Really? I didn't have any issues although I wasn't on much this morning.

More plug-in woes. This time 7A24 Vertical plug-in. Intermittent bounce on the Channel 1 trace similar to if you were pushing the “Identify” button. Channel 2 is OK. It's not really a big deal, just slightly annoying. So today pulled the covers and got the Siglent ready to do battle.

Except the plug-in decided not to show up for the show down. It's been on for almost 2 hours and maybe once every 10 minutes or so I see it bounce slightly. Certainly can't troubleshoot that. So I did a few pro active things like checked the DC balance pot (is OK) and noticed some noise of the variable control. Deoxit on that. It seemed to help but can't be totally sure. Other than that isn't much more I can do until it decides to fail consistently.

Put the shields back on the plug-in to heat it up more and so far it's steady. I fully expect it to start with it's antics at a later date. That's how my luck goes.

Later this week if the mood strikes me I may tackle the Type 1A2 plug-in fubar. That will be a hoot.

No problems here either. I hope it gets sorted quickly, I have some items on eBay that finish tomorrow on bids, I'd like to get a bit more for them if I can

This might be a long shot, but was the temperature like the other day when the thing played up compared with today's temperature?

The bounce might be caused by a faulty capacitor. Many years back on a Colour Telecine machine, one colour channel, kept getting a walking line tracking down the frame very intermittently. It particularly liked to happen when live on air. It was eventually traced to a single coupling capacitor in the amplifier chain. Moving a scope connection back up the chain and judicious use of Artic spray and a Hot air gun helped but didn't guarantee the fault which had a mind of it's own. It also was very likely happen just after one walked away in disgust and a colleague then saw it happen. Best of luck med6753 and keep patient.

Yeah, if a fat-fingered BGP "adjustment" ends up on the 3 minute news slot at the top of the hour in radio it is big. We've got CenturyLink as one transit provider at work. Not the only one, mind you. There was some scurrying around by management and others until the sessions were closed, and then things improved radically.

Ambient temperature/humidity about the same.

Yea, most likely. Problem is I'm out of freeze spray. I have order more. This plug-in is entirely those round 16 pin custom Tek IC's. If one of them is causing the issue good luck to me.

The bounce is sort of like this but a lot less entertaining and doesn't happen very often.

Edit, fixed.

Yep. This was mostly crap because it took out CloudFlare I think which is the go to for edge caching. We lost our entire AD and SSO (Duo) during it which was something I warned about and was ignored of course. So when the phone lines lit up earlier no one could log in and look at it

Wasn’t my on call weekend

I can't believe Summer is almost over. The apples are just about ripe. Next week the orchards open and the obnoxious and loud city folk show up clogging the roads. With the prior pandemic I'm sure this year they'll be out in record numbers. Thankfully by Oct 31 they go home and stay home.

bd139 · « **Reply #68212 on:** August 30, 2020, 04:54:48 pm »

Ahh apples. I remember them. Mr fuckity cunt the squirrel stole all mine this year. Next year he’s getting an extra and final orifice.

I send you some if you promise to stay home.

Really pisses me off when people migrate like that. You get them here, foraging in the bushes on the inside of blind corners on country lanes. I nearly wiped out a whole family once with my Land Rover

Ahh, but mine just requires a schoolboy, pencil, paper and the letters x, y, w, two brackets and two full stops; you're going to have to find a real proper line printer from somewhere and a box of fan-fold paper to do real justice to golden age ASCII pr0n.

A trivial challenge. Haven't found my GPO Tower, though.

I hope you all realize that as soon as Saskia sees this we are going to have to "unsee" some beefcake.

Fair is fair I guess.

I never knew squirrels eat apples, all they ever eat in my garden is nuts, not surprising really as I don't have any apple trees for them

bd139 · « **Reply #68218 on:** August 30, 2020, 05:31:00 pm »

If there’s no nuts they eat the fruit. Bastards!

I have learnt something today then. I quite like them, we have a family of them somewhere near us, and they are quite tame, they let you get upto about 6 feet away from them. They also are not scared of my cats either, and they can often be seen in proximity to each other, the squirrels are always that one step ahead of the cats though.

Excellent! One thing interests me; the hp is not simply obedient to the extref, it uses it as suggestion. Quite interesting design choice; the counters I've got (TTi TF830 and a small Philips) just throw out their own oscillator and immediately obey the incoming signal.

Two weeks late, but I had good excuses. The next <Toolpr0n> part, with the remainder of the alingnment toolkits.
A triple of Bernstein kits (bronze blades, special plastic, and one for Radio/TV:

A kit from the (defunct) company FriDaRem:

A special kit for Telefunken mobile radios with some additions:

A large kit from GC Electronics from the US, which also had to take some add-ons:

And my preferred Bernstein kit (guess what - slightly modified) and a ceramic aligner:

Phew. So, what to do next? Maybe saws?
