Ok all done. I resisted an 8840 DMM, 8640b signal generator, a pile of 54602s that needed repair and a tek 7623. Oh and two old Fluke 8020s which were battered.

Did buy a couple of books, a hoard of new (!) ceramic variable capacitors, a nice broadcast cap from alps, crystal socket by Millen, a couple of GDOs with coils, some panel meters and a nice little regen receiver though.

Edit: add image.

Just done museum of computing. Skipping Bletchley park today as it’s hot and rammed with idiots today. Will go on a cold week day some time later in the year!

Doing a few mods to the ADMS301 Microscope. I want to make a "ring" on my 3D printer to extend the base a bit around the outside. I find it a little small - maybe 2 or 3 mm extension. The ring will have it's own feet so it matches the height. Hmm what color? Oh yea black.  :-DD

Also, the power connector in the back for the two LED lights needs to be changed to a right-angle type. Sticks out a little too far and could get knocked and broken.

I am a Test Equipment Addict (TEA) - by virtue of this forum signature, I have now faced my addiction

I'm not going to bother to go to Bletchley Park again. OTOH I go to TNMoC repeatedly.

Yes that was excellent. It was pretty dead today so i got a 1:1 tour of colossus and WITCH and had a natter about the microcoding of the WITCH. Also lots of HP calculators and slide rules. Their A310’s power supply was duff though :(. Will upload photos later. Need to dash food shopping first.

Edit: also dekatron glory.  ^-^

Ditto.  :-+  I remember the sardine can radio on that front cover!!! ( Suddenly feeling very old for some reason... ;) ) And I'm a little jelly on the GDOs... especially since knowing you, it all followed you home after you "dropped" a 20 quid note...  :-DD

Ah yes the Tuna Tin QRP transmitters etc. They still sell 'em: http://qrpme.com/?p=TUNAS

Home now and inspection took place.

The Howes radio appears not to pick up a damn thing (typical). Looks like the front end FET is borked. Probably connected it to an antenna with some static on it. I will repair that tomorrow. It's a BF245 which I have a few lying around. There's no online manual for it but if you send GQRP club a picture of the rig they will send you a copy of the manual. Also pots a bit scratchy and it has a PL259 on it (die!)

GDO mark one. Works but there's a dead spot in the tuning range. Looks mechanical. I will debug this tomorrow. There was an exploded 9v battery in it but no lasting damage.

GDO mark two is in pretty good condition. Also an exploded 9v battery in it but no lasting damage other than the battery clip being nuked. And I don't have any of them left now so fixing that will have to wait a couple of days :( ... this one has no dead tuning range and is bang on the scale and frequency stable as I can tune it on my radio with a 200hz filter and it doesn't change tone  :-+

Edit: Yoda grade English fix.

Lol. £35 the lot. About £120 return on the stuff that’s going on eBay. That pays for the fuel and the trip to the computer museum and the bits I’m keeping (caps and meters)

Just on my way back from Gransden Airshow and you're right, it was 33C there and 27C in Chelmsford, I should have stayed at home I think, I don't do heat

For everybody that think that Canada is a dark cold place, this is where I spent the last 2 weeks.




On the shore of Lake Ontario. Water was actually more hot that the pool at home.

Tomorrow I need to get back to work, boooo  :--

Cool!

Hope the process of getting a visa or residency is not too complex.

Well I found out why that receiver didn’t work. Crappy toroid winding. One of the pads isn’t soldered underneath  :palm:.  Basically the antenna side isn’t connected at all ffs

Need to undo a “user modification” as well.  :palm:
