I'd like to be able to detect radio freqs between 10 kHz to 200 kHz, using the Propeller and an antenna. I'd imagine there would be a few other components.
I recently started riding a 250cc motorcycle, and on a 90+ degree day, getting stuck at a red light trying to turn left is the worst. Not only does the bike have very little metal, it has a lot of ground clearance (dual sport).
This is the type of traffic signal I'm typing about - https://en.wikipedia.org/wiki/Induction_loop
This is what I want to do - http://www.ebay.com/itm/Motorcycle-Green-Light-Trigger-Traffic-Light-Activator-Red-Light-Changer-New-/332153452418
I figured I would start with a Propeller data logger, with an antenna and try to detect frequencies, for fun, as a learning exercise,
and then later hopefully to be able to transmit some of these frequencies.
I am hoping to use a large AM loop antenna for now. The antenna calculator says I'd need one twice the width of my bike, which is another hurdle.
Does anyone have a starting point for me, maybe some code and a circuit that could pick out a higher than normal RF signal in the 10 kHz to 200 kHz range?
Edited, I can see how this could be confused with attempting to do something illegal, disrupt signals, etc. The guy running the eBay auction is no dummy, and did a lot of research. Although this is not illegal in any way, I am not building any transmitter of any sort, only a detector.
