The Engineer Posted April 12 Share Posted April 12 (edited) I bought a couple of old 27MHz 2-channel AM receivers to play with. One is an HPI RF-1, the other a Hobao HR-201. Both receivers use the same circuit board with a P8196R integrated circuit. Does anyone have a data sheet for this please? What is the supply voltage and which are the positive and negative pins on the supply connector? Thanks!

The Engineer Posted April 13 Author Share Posted April 13 There is no information about this IC anywhere on the internet. Not to worry I have worked it out by tracing the circuit. I found the pin that carries the demodulated output from the receiver so I can use my own data formats. Mike Quote Link to comment Share on other sites More sharing options...
