Some decades ago in Ausralia, playing with two shortwave receivers to resolve SSB, and hearing a very loud American voice saying: "FRESH FRUIT FRESH FRUIT THIS IS SKYKING DO NOT RESPOND" then a series codes.

How does it complicate the design? I'm learning about this area currently and working with the 'field replaceable' type connectors for > 10GHz. They're relatively expensive depending on the brand, but you can sometimes find surplus/used lots for sale at good prices.

Yes, some gaps in my education, too. I did some online linear algebra coursework to help understand quantum computation - EdX has several options from good colleges.
