Re: AM radio that use a chip for the receive circuitry


Hi All,

I would like to try my hand at using a MCU such as an Arduino to control a Si4735. 

Si4735's are available on eBay Australia 5 for $US7.14 ($AU11.55), but they are SSOP packages. 

My old eyes and shaky hands can't handle SMD's even with magnifying lenses.

Does anyone know if/where I can get Si4735's in a through hole package or on a breakout board?

Stay safe folks,

If you are in DIY RF and Arduino, you may look at this project:

There's a list of receivers using the SiLabs Si4735.

Si4735 is a formidable chip, it peaks the ferrite antenna automatically in LW and MW, provides 4 or 5 different AM bandwidths,  has a very competent FM receiver with RDS and can even load a new firmware live to provide SSB demodulation.

  Does anyone have a website with either a list of radios using specific chips for the receive circuitry
or a list of the chips used for receive circuitry?
