As I said I got a Hantek DSO2D10 from Amazon.? Delivered the next day, cost ?201.? This is a more expensive way to buy things but I'm uneasy about overseas purchases because of the difficulty of returning things.
?
It seems to do what I want, give reasonable scope type measurements in the region I'm interested in, the HF radio area, up to 50MHz if I'm lucky.? It's reasonably easy to use and the manual (68 pages) isn't bad.? Good enough that I can get it to do what I want reasonably easily.
?
I didn't go for the minimum cost.? From what I see minimum price things are minimum quality.? Initially as the price increases the quality increases rapidly.? Then there's a point where the price increases rapidly but the quality increases slowly.? You get to the point where the high price is part of the attractiveness.? I like to go for the knee where the quality/price ratio is at it's maximum.? I think I'm a bit below that with this but not by a lot.
