So r.r.a.h, if you are still reading, what has this humble newbie already
screwed up? I know the sensitivity is going to be extremely high, but I
should be able to fix that with some simple mechanics. My old LEGO bricks
should do the trick, come to think of it...


I'm doing a random wire "semi-automatic" tuner, and also trying to make
varicaps for it. I found a eBay seller from Germany, if I remember right,
who sells ready-made air-varicap plates. I bought few dosens of them for 20
euros. I think the seller ships worldwide. I'm sure there is other producers
too...

That's a rather good deal. I paid 25€ for material costs and an additional
5€ to my neighbour who got them for me. My brother who teaches handicrafts
at a school is going to let me use the workshop to do the rest of the
work, so right now I'm looking at a cost of 33€ for materials, but I still
haven't bought the plexiglass.

How is your tuner going to be semi-automatic, if I may ask?


p.s I can see you're a fellow Finn aswell, so here is a rather useful link

I'm sure Vekoy is a familiar place for you already, but still...
