Post Earpiece wireless reciever Reply with quote
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

You can buy some wireless mic's on EBAY pretty cheap. Maybe one of these could be modified to be used for an earpiece with a simple pre-amp..??...
