Re: Post a picture of a cat

Cats sometimes just clear off, probably to find a better billet. Sometimes they turn up on your doorstep out of nowhere. Occasionally cats which left years back reappear.

Mostly they are with you from when they are young. Now and then they come to an untimely end.

Looks like I've opened up another TimeNut rabbit hole (wormhole?). Interest mounted as I read. A hydrogen maser! A caesium fountain clock! I read on. The master is a Gents Pulsynetic but I don't know the exact model. What a let down. Some TimeNut you turn out to be. Can't wait to see what turns up....

Enter "cat vs snake" into YouTube and there are numerous videos about how cats have faster reactions. There are also videos on how cheetahs are just big pussy cats.

Re: Post a picture of a cat

Cats are wicked like that.

They also have other peculiarities, such as invariably choosing the most expensive and prized piece of furniture to sharpen their claws on. If they fish, they always pick the most expensive goldfish in the pond.

Re: Interesting findings on the internet

I wondered what you'd been up to.

It seems strange to have to use a VPN to access this forum. Do the Oz authorities have it flagged as a subversive site spreading disinformation?

I find at The Other Place that the tone often gets needlessly rude and aggressive.

I came across DAB about 20 years ago and noticed there was a definite attempt to push it. Radio programmes extolling DAB, where you could win a fabulous DAB radio, which was wonderful for all sorts of ill-defined reasons. The needle of my bullshit detector went FSD. Generally, if people believe a ne...

It's all about money. Follow the money. Operating even a single transmitter is expensive. Once upon a time, it was BBC credo that if there was a choice between a cost being borne by the broadcaster or the listener/viewer, then it should be borne by the broadcaster because that reduced total cost.

Sad. A lot of radio services are disappearing. In the UK BBC transmissions on 198 kHz will be ending on 27th June. This has been threatened for a year or two. Apart from broadcasting, it was used for other things such as controlling special tariff electricity meters and as a time standard. The frequ...

Re: Test Equipment Anonymous (TEA) : Discussion and Group Therapy Thread

I find this slightly disturbing. I'd assumed that if you feed a signal at say 10MHz from a source at 50R into a BNC cable and at the other end is an instrument also terminated at 50R, you get 10MHz out at the instrument. There may be some loss of amplitude, but there's no obvious reason why there sh...

I've been seeing some unexplained variations in the measured stdDev, so I'm reluctant to give figures at the moment. Those measures were very fast; 100 samples over 50s per orientation, with maybe 30s rest after changing orientation. On returning to the "0" orientation, the frequency and ...

No, I haven't cleaned contacts, measured cable capacitance, etc. I did consider adding a crude extra external buffer before driving the cable, but on reading the 10811 manual and playing around, I decided it was more likely to cause noise problems than to cure frequency variations. At this point li...

Picturing the quartz inside the OCXO as a wobbling bar, I can imagine that if it was horizontal and right way up up, or upside down, gravity would have an effect. On its side either way, or on its end either way, not so much so. Which way it was used I'd guess would have an effect on ageing. The eff...

I've opened an HP OCXO to replace a thermal fuse. You can get to it without unfurling the bits that shouldn't be disturbed but the outer metal skin needs to be removed. It's in a socket but that might just be to simplify assembly as a soldering iron would definitely open it. It's a very small wire-...
