A 30 year-old electronics hobby kit still lives on to this day.
I came across a superhet airband receiver kit that peaked my interests. It’s based on a few venerable but not extinct radio ICs, namely the NE602 and the MC1350. I don’t know where the kit producer is sourcing these ICs, but for $20 it was worth taking a chance on it being more than a pack a of bubblegum. Fingers crossed I receive at least functional equivalent ICs, if not new/salvaged old stock.
You can find the kit at the usual places searching “Air Band Receiver High Sensitivity Aviation Radio 118-136MHz AM DIY Kit”
The schematic is to clean and logical to be a typical noname solder kit. After some digging around on the internet, I found the origin of the kit. This project was originally designed by Fred Blechman and published in the spring 1994 issue of "Electronics Hobbyist Handbook" by Gernsback Publications.
A pdf of the publication is available here:
Tony van Roon also shares their experience and analysis of the project kit here:
