Went out today for an adaptor (BNC to SMA) and ended up buying a 2M/70cm handheld (oops), why is this significant you may ask. I have already forgotten how to program it despite having the manual next to me. I seems to be able to do anything, must make a list of what I want it to do and get my fountain pen out and make a list of how to do it. Am I the only person to have a 'Red & Black A4 notebook on the kitchen table for notes? And one at work, one in the workshop etc..

I must admit the comment about whistling open a local repeater brought back memories.
As for forgoten knowledge,
Estimating how much more time you can get from a length of carbon burning in an arc lamp.
Splicing and joining film.

Is the bayonet cap light bulb in danger of being forgotten?

Seems to me it is, as all media articles now feature an Edison screw and DIY stores are full of them.

I don't understand why we now need it after all these years?

Having been prompted about “forgotten knowledge” and talking to friends here are a few more!!
1) solving Rubics cube ( no taking apart or pealing stickers)
2) correct “angle” for a ladder (remember a wooden ladder can only be right way up and also not back to front )
3) re handle a hand tool (hammer , spade , axe etc)
4) skimming stones
5) fly a kite
6) the Imperial system , thumbs up to the U.S.A.!
7) The correct bending of split pins , not turning the legs into springs. The letter “R” comes to mind!
8) The correct way to fly the union (jack) flag....Even one of our M.P. Local flyers got it upside down!! but in there defence it was next to the title “Delivering REAL change and a REAL say” DO YOU LAUGH OR CRY??!
9)What LOL rely means (SWALK)
10) I saved the best till last.. Correct sequence of the use of “lock nuts” when one is thinner than the other . I think a lot of people even in times ago didn`t know.

Regards S-W

I'd just been doing that before checking the forum. Files are easier to get then they were a few years ago - loads on e-Bay for instance.

Getting out of bed just before the crack of dawn, down to the fields in the early morning mist, to pick mushrooms to have with bacon and eggs for breakfast. But, most importantly, having the skill and knowledge to know, by sight alone, the difference between a mushroom and a toadstool. On the way home, a detour to the farmer's house to collect newly-laid eggs - and, preferably, duck eggs.

Hmm - now I'm hungry - I'm off to the kitchen.

And which we call 'American English'. But here, in the U.K. these days, I seem to hear & read a great deal of what can only be termed 'English American'.

I suspect merlinmaxwell may have meant that the Americans have two names for the Imperial system (of which they are so fond) - they call it either "English" or "Standard".

I think the American measurement system is called SAE.

As someone who learned SI first, I cannot agree with you there. Good riddance to it, I say.

I've not read the whole thread but here's my take on it...

I think that many hobbyists are becoming isolated from the highly integrated technology inside modern appliances. eg it's far harder to tinker with high tech stuff like DAB radios, SDR radios and modern ham gear compared to the stuff produced 30/40/50 years ago.

The fallout from this appears (to me at least) to be a generation of people who don't want to tinker with or understand things too deeply. They are happy to buy stuff and then go online to look for freebie hacks and firmware tweaks to get the most from their latest purchase.

Because this info is so easy to download there really is no need for them to think too deeply themselves. They download the hack, apply it, have fun and then move on to the next 'must have' item. In terms of getting results it's a far more efficient plan than learning how to do it for themselves.

The plus point of modern technology and the internet is that I think there are far more electronics based hobbyists than there used to be but I also fear that there are far fewer 'original thinkers' amongst them.

But I suppose the internet can be used as an instant reference library to act as a knowledge/thinking extension so there really is less need to learn and store skills and knowledge in our heads. A lot of the forgotten knowledge subjects mentioned on this thread can be found on the web so it is just being stored and passed on in a different way. The internet is such a game changer.
