So this may make no sense but I thought I would throw it out to you smart people. Looking into ways to relay information through the use of CB Radio transmission. Wondering if there would be a way to relay radio through an Arduino board?
Alternately has anyone done any work with wireless transmission between two Arduino boards? Looking for something that could work over a decent distance, possibly in an urban environment.
Thanks.
CB not a reasonable choice. Channels are too narrow, transmissions are AM or SSB.
Also, IIRC, the FCC regulations prohibit data in the 27MHz CB band.
MURS or Amateur Radio (licensee).
Are you the one that asked a similar urban-area wireless in another thread?
Plus there’s that minor detail that it violates FCC rules, but who am I to be a stickler for such things. 
I hacked a pair of those cheap FRS radios to send what amounts to DTMF tones over the air. Worked like a champ.
$20 for the radios at Walmart or wherever you find them on sale, a bit of cutting, some soldering, some FFT code on a PIC on the receiving end, another PIC and some DTMF code on the TX end.
Done and done.
Skimask, this is exactly what I am planning to do. Can you refer me to your project or provide more detail?
Anything would help to get me started.
thanks, Shawn
