https://test-equipment-for-sale-wanted- ... ssage/7036

This Fluke 760A Voltage Calibrator is in good cosmetic condition and was working fine when last tested a few years ago.
Health issues mean I cannot test this again, nor can I ship it, it is far too heavy for me to pack, so it is offered without charge to anyone able to collect it from the Dunoon area in Scotland, otherwise it will have to be be recycled.
It will come with a printed manual if I can find it, or a copy of the pdf scan I made when I bought it.

Is that you or someone else? If they were on this side of the pond I'd take it off their hands in a heartbeat.

Not me.

There are two reasons I'm not interested: AC not DC, and 38kg

[MED6753]

I have plenty of DC sources but severely lacking in an accurate AC source.

[tggzzz]

I have 1V and 10V sources plus a 7decade KVD. But not 1kV. Wel, I do have a 1kV electrophoresis PSU, but it is too noisy to be useful; thought required.

I also have a Fluke515 calibrator, which does AC and DC to 100V.

For AC I use a standard signal generator, and measure the voltage. I presume the AC voltage won't vary up to 1kHz, so measure the min and max voltages of a 0.01Hz sine wave, and calculate Vrms.

I also have a Datron 4902/1/3 calibrator: serious kit, no instruction manual, 1kV output doesn't work. Perhaps just as well given all the exposed wires and terminals at 1kV

It's an 8 hour drive from where I live. That's without a break, and at least two would need to be fitted in. I find a three hour drive is about as much as I find tolerable. Anyway, a day's traveling, staying somewhere overnight, then a day driving back.

Tempting, but all considered, I'll pass.

For a long journey, I prefer 2 hour stints between breaks.

I could find other things to do on the way and near Dunoon. Hence I'd turn it into a mini-holiday.

The 38kg is the deterrent for me. I want to avoid repairing my floor and spine for as long as possible.

I went up to the Solway Firth goose shooting once. I did bag a goose. A lot of people go there and don't. This is another three hours driving. I suppose there are other interesting things to do on the West Coast of Scotland.

holy crap med......are you hearing the pissing and moaning from these brits about driving a couple of hours?

to recover a crusty smelly tek scope med drove 5 hours to my house......went over and toured the Gettysburg battlefield....and then turned and burned for home.

and he seemed to enjoy being out and about.

before retiring it was not uncommon for my fat ass to leave the house about 5 am and drive to ft Bragg in NC (7 hours). we would usually get sucked into meetings after handing off the goods, and then head for home at 3 or 4 pm. granted, we always traveled with at least 3 in the vehicle because we were carrying classified both ways, and two guys had to mind the goods while one at a time we ran into the rest stops for a pee. and before actually heading for home it was necessary to stop at the compound, open the scif, secure the material in safes, reset the alarms.....and then head home. was lucky to be back with swmbo by 1 or 2 am.

here in the land of the free we don't think about distance as a problem. you guys need to get off your tiny little tea sipping island sometime.

ps surely an Aussie or two will now tell a story about driving for 3 days without bothering to stop for a piss.

pps ok.....must apologize in advance for my cranky tone. the back just popped off my phone because the battery is swollen like a watermelon. new phone ordered. but in the meantime there is a worry that it could ignite my facial hair.

Yea, seems like some sissy fussing to me. (i kid). The trip to your place was an 11 hour round trip. I was tired but I got it done. Last year drove to Florida and put in two 12 hour days. Years ago it was one 21 hour bonsai blast non-stop. Won't do that anymore.

[Zenith]

It's an eight hour drive, done without stopping. There may be road works, dropping the speed to 50 MPH. There'd have to be three half-hour breaks, then there's a ferry trip. That has to be over 10 hours traveling. There's no question of going there and back in a day. So there'd have to be an overnight stay in a B&B. I don't think it's a light undertaking.

I do a few three hour each way trips a year. I think the hassle of a car journey increases disproportionately when it's longer than four hours. It makes a difference if there's more than one driver.

[MED6753]

Almost forgot. The mother of all trips. 6 years ago. 2.5 days. Colorado to New York. 1800 miles. Alone. Was definitely not fun.

I had a girlfriend whose father used to drive the family from Los Angeles to Michigan, somewhere near the shores of the lake, to see his family. The journey was 2,300 miles and took days, with camping stops. She looked forward to it with dread. To make it worse, she and her grandmother hated each other.

Over here 100 miles is a long way, over there 100 years is a long time

I was once in Copenhagen (Denmark) and had a couple of days to spare before getting home. So I went to Stresa (Italy) for an ice cream.

Wouldn't do that now, since some ice cream here is decent.

These are British roads, they aren't long and straight, for the most part, where you could hit cruise control and doze off. Our roads are very narrow by comparison, and demand constant attention, especially in remote areas like that.

If it were a breeze to drive there and back, I'd have it myself.

Well, would be better than I expected.

Gurgle indicates 370 miles 6.15hours to Glasgow on motorways, then 35/90 miles and 2 hours to Dunoon, depending on whether you take the ferry. The 90 mile variant wouldn't be along single-track-with-passing-place A-roads, but would be on roads that might be classed as B roads here. Probably more sheep/cows/deer than cars.

35kg whichever way

I had a colleague in Bristol who'd worked in the oil industry in Aberdeen. There was difficulty selling the house and his family were still there, and he'd make the trip fairly regularly. 8 and a half hours and 500 miles. Once he picked up a couple just outside Aberdeen, who were hitch hiking and wanted to go to Exeter. They seemed very agreeable and it was more pleasant than driving alone. Bristol is on the way to Exeter from Aberdeen.

When they got to Bristol, it was getting dark, I think it was autumn. He said it didn't seem right to leave them to hitch hike in the dark, so he drove them to Exeter, which is another 80 miles and 90 minutes, and then he drove back to Bristol. He said the trip to Exeter didn't seem far after driving 500 miles.

Then I take it you are not into boatanchor comms receivers.

RA17 30 kg
AR88 44 kg

Certainly not! Boring things

I might be tempted by an HP8566 at 50kg, but that splits into 21+29kg lumps. Fortunately I have two 21GHz SAs that are more than good enough for me, but I would prefer they had preselectors.

[MED6753]

I visited Scotland in 2001 and rented a car and had my experience with right hand drive. Didn't make any stupid mistakes especially at roundabouts. So I know what most of the roads are like. Narrow and twisty.

Problems are...

If I was in the centre of a narrow lane with something coming the other direction, I hope I would move in the correct direction - unlike some cars with automated lane keeping.

Coming out of car parks/petrol stations when there aren't other cars around to give me a Big Hint. My ex fell into that trap, even after saying she wouldn't!

And a strange one... Both me and my ex regarded "turn right" as "stop and turn across the oncoming traffic". We resorted to "turn your/my way" to avoid that Neuro-linguistic programming.

Boatanchor radios were what set me off on this TE thing. They need swept alignment. 20 years ago, it seemed very hard to track down a decent sweep generator at a reasonable price.

I splashed out and bought a Siglent SSA 3021X (2.1 GHz), which has now been persuaded to identify as an SSA 3032X (3.2 GHz) with all options. I might have gone the extra mile and bought the plus version, which can be further persuaded to be a VNA. 3.2GHz is more than enough for what I do. Oddly enough, I find it's made me not very interested in vintage spectrum analysers, which are rarely very cheap anyway. However, I find a similar effect has not set in with scopes. I do have a 150 MHz modern DSO, which is the go to scope, but I'm still drawn to analogue scopes.

Seventeen & "a bit" hours flight from Perth WA to Heathrow, an 8 hour drive to Dunoon, then back again. On top of that, the airline might not let me take it as luggage, so perhaps not--I'm getting way too old for this shit!

I think I've told this story before about how two of the British relatives visited when I was a little kid. They flew into Montreal and stayed with my grandparents there and several days later the four of them drove from Montreal to my family's house in Toronto. Before they left, my grandfather apparently unfolded a map on the table and showed them the route. They didn't understand the scale of the map though and when they arrived at our house in Toronto about six hours later, my relatives were completely wiped out from the drive. This was despite the fact that they were passengers and my grandparents lived in suburban Montreal in the west end of the west island a couple of blocks away from Autoroute 20 no less which gave about a 30-40 minute head start vs. leaving from the central part of the city.

They also pushed hard on a different visit to postpone a wedding in Montreal due to what must've seemed to them to be a massive snowstorm and extreme cold. It was certainly nasty, that's for sure, but within what would be a normal winter storm for Montreal. They only visited a handful of times but each time they did, they found coping with the scale of things in Canada to be challenging.

[tggzzz]

I've had similar experiences in the US...

Taking an hour to drive the "five miles" from Palo Alto to San Francisco.

Taking all day to get to a hotel just outside Yosemite Park. Then taking an hour to get there from there to the car park in Yosemite village.

Up in the Rockies, seeing neighbouring villages (Moffatt, Hooper, combined population 3% of the village I live in) 20 miles apart. In between I expected to see Clint Eastwood appear on a horse.

100 miles vs. 100 years. My house in 95 years old. My parents house was 170 years old. Then we get to old houses. I enjoy walking down streets 2000 years old, and sitting on rocks placed in a circle by people completely forgotten to time who spoke in an unknown (and forevermore unkowable) language. Or crawling under rocks into a barrow called Hetty Pegler's Tump, named after a recent owner in the 17th century.
