nice work nico, i wonder if the receiver could be made smaller the transmitter does not matter, but made smaller i could put the rx in the left cup of some headphones (deaf in one side anyway), i usually have just one cup on my phones, but i would go back to two to make them wireless.
when i'm on the beach the wire gets on my tits, any chance of the schematic, parts list etc.
thanks aly.
p.s. the plastic version of you rx box is what i used for my barracudas, the smaller square one for the batteries, exellent cases.

we have discovered that the system that is used by the brand XP metal detector is the same as used for 2 modules sold by Aurel marqur TXFMAUDIO and RXFMAUDIO. This morning prospecting with a friend he had a wireless headset brand XP metal detector and as soon as he had started it the TV reception issued by my camera aurel TRANSMITTER signal. and vice versa as soon as he put his detector road I captured her in my aurel detector receiver

i'm currently researching the possibility of using fm radio band, after reading your thread i remembered i had a pair of those headphones with an fm radio built in, i plugged in a cheap mp3 transmitter in the MD, it worked well but the range was way more than i need, so i will make my own fm receiver board for the phones, tuned to the mp3 transmitter.
but thanks, if i had not seen yours i would not have thought of it.

ok , ok, I also think a FM system, the MAX2606 VCO apparently works well in 88-108 in issuance so. I found a miniature pcb on the web at this address. es, but it will not be disturbed by the external environment?

here is the link in the pcb so smd.

Hi ashefr,
I've been looking at the internet but it seems Aurel has a few modules.
Do you know the exact type of module that was used?
Was it the Aurel TX-FM-MID/EN FM Receiver Module 433.92 MHz?
