EEVblog #575 - DIY 1970s Spectrum Analyser

What about a good kick ass open hardware SA? If he did that 33! years ago where are the good DIY SA nowadays? Probably everybody is like me now: for test equipment find the product you like and drop some money from the bank out. So sad....

Scotty's SA is a stellar performer but pretty complex.
Looking at ex. Tektronix guru W7ZOI he almost duplicated the Aussies     http://w7zoi.net/sa-stuff.html

Others have been using old cable TV tuners as frontend... I think I do have one that I started to convert to a SA... never completed

That's a great video, but the real question is: what were you doing at that ham meeting? Informing on how to get a license? (Personally I think that would be awesome).

Remember: being a ham doesn't mean you are required to make contacts, it just means that you have a license to build, operate and experiment with transmitters. All the rest is folklore (nothing against it at all, don't get me wrong - but if it's not your cup of tea, simply don't participate).

What kind of oscilloscope is he using?

Looked like and old Hung Chang to me, but I didn't look closely.

I was invited to show off my CH7 TX gear, its was a retro 70's/80's night.

Just saw this one today. I used to work with Phil around 25 years ago (early 90's). He wasn't as grey then, but a really nice bloke and great engineer to work with. If he's now messing with traffic controllers I can guess where he's working now. Nice to see some of his old home brew kit again.
