Post by thread:[PIC] PIC-based Spectrum Analyzer

It seems that someone recently (past 6 months) posted information about a PIC-based spectrum analyzer. If anyone remembers where or who, please let me know. Thanks, Richard the senile

A Pseudo Spectrum analyser feature in it, A philips I2C TV tuner 42MHz to 862 MHz can also be hooked to PIC with GLCD and make a toy spectrum analyser. Add 35MHz to 42MHz filter of desired bandwidth and detector.

Nice though. I always think of 100KHz to 18GHz when people talk about Spectrum Analysers :-)

I tried a search, but it returned an error. Based on Scott's reply, I must have been doing something wrong.
