'[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

I can't remember such a post recently.
Might be worth doing a search of the archives if you haven't tried that already.

I did a PIC based Cat controller for FT817 ND radio. 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 :-)

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

There was also one in a recent (last 3 or 4 months) Circuit Cellar, using a dsPic to do a similar display using LEDs. Apparently it is very fast in updating the display in real time.
