Re: A Dark Spectre from My Past; "Hobbies Weekly"
I remember building a (PW?) "Elegant Seven" radio kit when I was at school in the 1960s. I came unstuck when it specified that I needed a signal generator to align the IFs. Since I hadn't an inkling of what an intermediate frequency or a signal generator was, the project was abandoned. A lot of pocket money wasted!

Re: A Dark Spectre from My Past; "Hobbies Weekly"
Yeah, so it wasn't just me who found a Skyrover completely inoperative!
I feel so much better now! David

Re: A Dark Spectre from My Past; "Hobbies Weekly"
Took me months of snipping out germanium diodes from duff transistor sets at the age of seven before realising that the inabillity to receive anything from my crystal set lay in a poor aerial.
Once I had discovered the dial stop on the telephone, I was away! My parents were not so keen to have me crouching by the receiver with a crysal earpiece in one ear every time they wanted to make a call... Rob |

I too remember the Woolworths stuff but ISTR reading it wasn't suitable for electrical joints before it claimed any pocket money. I persevered with Dad's old 100W (?) Solon and an old reel of 16gauge "NOKORODE" or some such name rosin cored solder. At some point I built a couple of Roamer 7 sets (horrible misleadingly advertised things) and then an Elegant 7 which worked OK but needed a separate aerial trimmer for years until I finally learnt how to track it up properly.

Re: A Dark Spectre from My Past; "Hobbies Weekly"
You are not alome, Bazz4. In the early 60's I mastered the art of making crystal sets and decided to move on to a single transistor circuit. Would it work - not a jot! Several times I tried, first with those 'Bi-Pak' surplus transistors, then with genuine OC44's etc but no joy.
One of them did produce some very weak audio, but it did this regardless of whether the battery was connected! Finally one of them worked, and after that they all worked! My masterpiece was a 3 transistor set which used an AF115 RF amplifier with a reaction coil on the ferrite rod, followed by two stages of audio. Careful setting-up could drag in Radio Caroline, no mean feat here in Manchester. Has anyone else had the same experience ie struggle for ages and can't see what you are doing wrong. Then - for apparently no reason - one works and from that moment all future designs also work? Wrangler, I too had a Trionic kit and I only ever built the radios! All the other stuff - alarms, light flashers etc didn't interest me. Mine must have been a later one than yours, as inside the domes were AF115's.

Re: A Dark Spectre from My Past; "Hobbies Weekly"
Reading all the problems people had with early transistors and sets, just makes me thankful that I started with valves.
At least they WOULD work, and the few (many?) shocks you got made you more careful in the future. |

Re: A Dark Spectre from My Past; "Hobbies Weekly"
Well, after the skyrover transistor kit debacle, I did go back to valves. 14 of them!

I fell in love with the Practical Electronics "War Games Computer" (1971, September edition). Had a Ledex switch, a telephone dial for data entry, all sorts off stuff... Got a loan of 20 quid from my parents but I never finished it... Learnt a good lesson though... "Try not to have more than 15 unfinished major projects on the go at any one time"... Still trying to enforce that one...
