Hi All
Does anyone know of (or have experience with) Audio over RF? I'm referring to analogue left and right Audio between 20Hz to 20kHz. I need to cover about a 20m distance so a Dorji transceiver might be suitable(?). In my part of the world the unlicensed bands are 433MHz, 2.4GHz and 5.8GHz. The FM band is out of the question due to communication restrictions.
I'm not sure if a PICAXE can do this or if there's too much information converting from analogue to digital, transmitting, receiving, error checking(?) and convert back from digital to analogue for use in and Audio system.
Can anyone give some guidance on this? There are plenty of "AV Senders" on the market, but, speaking very frankly from first hand experience on many other jobs and using a number of different brands, they are generally crap. I've only found one ready made unit that is apparently "digital" and apparently provides "crystal clear audio" but I do remain slightly skeptical. The unit retails for $109-00 so it's not outrageously priced if it actually works, but, I am still interested in seeing if a PICAXE could do it or if others have further suggestions.
I look forward to hearing from everyone.
Regards,
Brad
