Instead scopes

It /does/ look a bit messy.

To get nice even spacing in hand-wound coils, I would pull on the wire until it gave just a bit, then wind it tightly spaced on a mandrel of appropriate size and finally, stick a toothpick, or something like that, transversely through the turns, 'screwing' it from one end to the other. My coils ended up looking perfectly neat.

Another method is to wind two wires tightly side-by-side to get the correct spacing, then unwind one of them.

I recursively used another Sharpie to make some tic marks, to space the turns.

Stretching magnet wire makes it beautifully straight, but wrecks the annealing and somewhat increases the resistance. Beauty over function.

My inductor is wound from #14 AWG, which takes some muscle to pull straight. Use horses maybe.

There's actually a drawing!

Can't comment on that one but I have a much older 4ch 200MHz scope from Instek, the GDS-2204. I bought it because it had less noise and less EMI than a similar Tektronix back then, plus way more memory, at half the price.

Long story short, I am happy with it but the software is quite buggy. It also drifts a bit in the baseline but for an RF guy that doesn't matter much. Remoting it from a lab bench PC always worked well and made the documentation job easier than USB-stick jockeying.
