Re: Test equipment recommendations

The nanVNA is not going to serve you as a scope. Have you considered building some (or all) of your own test/measurement gear? In my early teens such things were beyond my reach so my first measurement gear was a homebrewed V-O-M in a cigar box. If I could do things like that so can *you*. There have been homebrew scope designs over the years in various publications. One was in "73 Magazine" in two issues in the 1970s and the article to look for is "Eyes For Your Shack". The entire run of "73 Magazine" is available online. Google can be your friend. You could look at that article and any others you can find for inspiration to build your own.

As for eBay and those disclaimers avoid those like the plague (unless you only want a box of parts). Get something from a seller with good ratings and an assurance that the unit is not junk. Not everybody on eBay is a scoundrel.

I hope this helps.

Very off topic. My mind is wandering since passing my foundation, getting my call sign and now waiting for a radio. The Baofeng I ordered at the beginning of April didn’t arrive (woop!) and I got a refund. The next day delivery FT-65 to replace it which I ordered on Thursday is coming on Monday. My uBitx is awaiting a despatch window. My CW isn’t good enough to use my Forty-9er yet. I can’t afford a FT-817.
So, I’m tinkering with circuits, arduino and so on. Of course whenever I google something there’s an oscilloscope in the article. Since I was a kid I thought I needed one but they’re pricey. Does anybody know....are those twenty-odd quid digital things any good? e.g. JYE Tech DSO138 Mini Digital Oscilloscope. I’ve heard good things about the NanoVNA and I wondered if these little ‘scopes are reasonable in the same way.
Or maybe I’d be better getting and old style big box scope from eBay and hope it works (“Spares only, turns on, but no way to test it” is the standard disclaimer)
Better still, what do people recommend for basic test equipment?
