I'd really like to learn more about radios and RF electronics. I have a pretty good understanding of the system level concepts behind radio, and I have enough EE concepts down to understand things like amplifiers and filters, but chaining all of that together into a working system is above my level of understanding.
I think I have a small problem in that I don't know where to start. I don't know how to bridge the gap between block diagram understanding and detailed circuit schematics and diagrams.
Long shot, as this is a mostly programming based thread, but hey, I've gotten lucky before. Maybe I will again?
- jrowley 10y agoI'd recommend trying to build something relatively simple (e.g. an AM transmitter) from scratch and just enumerating all the questions you ask in the process. Then finding the real answers to those questions and the whys.
- cushychicken 10y agoI've thought of trying that, but part of my stumbling block is that I'd need an oscilloscope to debug the thing when it wasn't working, and those are sort of expensive. (At least, the decent ones are. About $1k or so to start.)
- jrowley 10y agoDigital ones are expensive but you can get an old used analog scope pretty inexpensively, and often they'll do the job. At least for relatively low frequency projects. Call your local universities surplus department and see if they have any or expect any to come in soon.
