  3. Lovely! I’ve seen the Raspberry Pi being used as a “pirate” FM transmitter , but a rather ugly one because the frequency modulated, square wave drives the antenna without any filtering! using a (aptly named) pi filter must make it tidier. Must… try this out to evaluate my antenna performance.

    That will kill the output, A pair for 5.1 zenners back to back would work

    This is great.
