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. -- Mouse.

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. Geoff. -- Geoffrey S.
