Human, this box is unacceptable. It has holes in it.

Pat, sorry to hear about Gilmore. We do grow attached to our pets. And yes, Schottky does look exactly like Harley.

Our cats are the only domesticated mammal that isn't "domesticated". Case in point. About a month ago one evening I came into the kitchen and found Harley laying on the floor next to a dead mouse. Harley is an indoor cat and has never seen a mouse and in the 2.5 years we lived here we've n...

Harley likes to sometimes give me a "love bite" on my hand and his fangs break the skin. He doesn't comprehend that it's painful. My cat Loki has the same habit. While stroking him, you have to be careful, otherwise you'll get a hurtful "love bite". Does he also bite you on the ...

This guy also found out the hard way. Supposedly the tiger was just giving him a "love bite" :roll: https://abcnews.go.com/US/oklahoma-animal-handler-attacked-killed-tiger-performance-sheriff/story?id=125792975#:~:text=Oklahoma%20animal%20handler%20attacked%20and%20killed%20by,demonstratio...

On the subject of cats (albeit large ones), I had breakfast at "The Shack" https://www.communityad.co.uk/exclusives/100-years-shack-cafe-hook/ on Saturday. There was a poster above our table telling of a little history. Apparently, the owners of The Shack also ran a fairground where one o...

Small and light electrons tunnelling through barriers is ... old and boring. So how about hydrogen atoms tunnelling through barriers? https://pubs.acs.org/doi/10.1021/acscentsci.5c00943 and an easier exposition at https://www.science.org/content/blog-post/tunnel-away Any practical applications? Did...

Shame about the unfixable 485, but at least it's proven its worth by repairing another. My 485's EHT died completely, leading me to suspect the transformer or drive transistor rather than associated rectifiers, but I hit the same problem that it was buried and I had another (brand new) 'scope (TDS3...

A little off topic but I must inform bd139. Your heart throb buxom redhead Christina Hendricks is in a Netflix series "Good Girls" which is a pretty good watch in addition to the eye candy. And boy is that some nice eye candy. :lol: I don't know if that series is available on Netflix UK bu...

More 485 drama. I pulled out my 2nd 485 to give it a dust off and power up and the A Triggering was nowhere to be found. So I took the "low road". I pulled the trigger board out of the 485 I condemned yesterday and installed it. Problem fixed. https://imagizer.imageshack.com/v2/xq70/924/Ao...

Here's one of the functional 485's on top of a 2235. The later series of portable TEK scopes tend to be much easier to service with the advent of LSI circuitry. Those 465/475/485's were still packed with discrete components. https://imagizer.imageshack.com/v2/xq70/922/8ngSAy.jpg And now that bench 2...

Gang, the party is over. The following pictures are the parts unit with the trigger board and PSU board removed. U1600 (X6 multiplier) is located in that board right rear with the shield. There is no way to get that board out without nearly disassembling the entire scope. And to add insult the manua...

He's dead Jim.

Let's clear up some confusion and I found the reason for the compressed trace. First, the trace is linear as shown. Second, there's a vertical issue too. At that attenuator setting (1V/Div) that trace should be 5V or 5 divisions high. It's barely 2.5 divisions. I verified on another scope that it is...

Getting some lab time here is like pulling teeth. Something always seems to come up that's higher priority. But I finally got the 485 reassembled even after a side track of pulling the PSU board to retrieve a dropped screw inside. So initial power up. No smoke which is surprising. PSU voltages in sp...

Have seen lots of brown tants. Just as bad as the yellow ones.

If you're running Linux you're probably OK. Windose 11 here and that Netgear program is built into my router so it never got near this computer.

My Netgear Amour program blocked that site as potential malware. You may want to scan your computer.

Nice haul. My father had one of those Heathkit M-1 "Handitesters". My brother currently has it.

You're much braver than I am, probably because you are familiar with them. Analyzer stuff is all voodoo to me and I'd never buy one of those plug-in's unless I got it for free. :D I was looking at the 7L12 pictures and all the calibration points most likely requiring massive amounts of highly expens...

The standard attire for most aged hams here is typically greasy hair with a baseball cap, scraggly large beard with evidence of the last meal embedded in it, large pot belly, and bib overalls.

Oh yea.....lots of unwashed grubby looking hobos sitting at a table with coffee and donuts. Is it a requirement that hams must look like they come out of the cellar once a year? :roll: Amateur radio is an ageing hobby in the UK, so there aren't that many young people at these events. There's a type...

You guys are lucky. Ham fests around here are few and usually have maybe 5 sellers at most and almost no TE. There's one next Sunday but the last time I went to it there was nothing except one seller of new RF equipment and the ARRL. Oh yea.....lots of unwashed grubby looking hobos sitting at a tabl...

Plans today to install the attenuators and attempt at power up went slightly askew. I was able to salvage legible push bottoms for the B/W Limit, Beam Find, and Norm Trigger from the parts unit. The Horizontal and Cal push bottoms from the parts unit were either missing or totally illegible. I notic...
