Has anyone experimented with the Si4703 or one of its breakout boards?

The RF/audio specs look attractive, and it should make a fun Arduino project!

Wonder why they would use such a hard to get chip?
(only one of my wholesalers carries it)

Silicon Labs lists five distributors for west Canada...

But that's not much help if they don't stock parts :down:

Heh, that's just it. Just because they're "authorized", doesn't mean they carry them.
I get all my stuff in the US as the shipping on BIG orders for my store is cheaper and faster. Few Canadian distributors meet the level of service I need to run my store :(

Despite finding little interest here in the Si4703 I went ahead and made a breadboard FM stereo receiver. It uses a UP/DOWN toggle switch for frequency selection, and a LCD for frequency display. A pair of 7 watt bridge AF amps drive Micca MB42X speakers (the best sounding pair of speakers under $100 that I've heard). Sound quality is impressive while RF sensitivity of the Si4703 beats that of my portable sets!
