Earpiece wireless reciever
Posted: Sun Dec 07, 2003 8:19 pm
Hi,
I'm trying to transmit audio from a base transmitter to a mobile reciever to connect to an earpiece. I don't mind the band or range being used as long as it is legal and only needs to go 30m or so... I can use a similar (not the same though) one to my radio mic, which works on about 49.82MHz
I am doing this wirelessley and in the UK so needs to run on uk frequencies where you do not need a license.
I am looking for some circuitry to do this (or a schematic
), and needs to be low powered and only operate a distance of 30m or so...
I don't mind self build circuits and have access to print PCBs if need be (using TechSoft PCB Design and Make) and will eventually make some cases for it.
I am not sure if you can use a standard signalling circuit like in keyfobs but connect a mic to the data lines or something...
Thanks,
computer
