Winding coils?
 

Has the era of winding one's own coils passed into history?

I remember in about 1965, or so, only knowing the word, "former"
in the context of "latter" and "former" and having a strange conversation
with Mr.Bullough in one of the local radio shops as the result.

But, the result was advice to wind the coils on a tube from the Ajax
range of kitchen scourers, and Mr.Bullough sold me quite a bit of DCC
wire with which to wind.

(And deep in the junk box from a silent key sale from some years ago, I have
a reel of silk covered!)

Mr.Bullough's claim to fame was that as a lad he charged the batteries for
Marconi's
experiments at Weston-Super-Mare.

Anybody remember the chemical "Nodon Valve", a form of home-produced wet
rectifier for rectifying the mains used in them thar days?

The design for the first ATU I was supplied with was described as "wind
60 turns on a bog roll holder". Once I started to use them for Txing I
moved to ceramic formers.

In America we called them toilet paper rolls or toilet paper cores. I
still look longingly at them when I throw them out.

I did however wind a few coils yesterday for an active antenna. They were
would from hookup wire I had around, and Soviet made 10 inch ferrite rods.

I measured the inductance with this little Chinese made component meter,
identifier and ESR meter that I got for $20 off of eBay. No box, connectors
hard to use, but it works.
