Here's a die photo of the FM radio chip, the TDA7000. You can see the greenish silicon, with white metal wiring on top. The 18 white squares around the edges are the bond pads that connect the die to the chip's pins, with gold wires attached. I've labeled the main functional blocks of the chip. 2/N

@kenshirriff I built a project from Radio Elelectronics magazine that used this chip. I never got it to work at all, even though I painstakingly copied the board design and everything.

@kenshirriff Why do we not have FM radio on smartphones? I know most FM stations have streaming services, but sometimes you can’t get cell service or you don’t want a delay (when listening to sports or listening to music accompanying a live event).

@kenshirriff the past feels more futuristic than today to be honest!
