    Re: Regarding wireless Headphone

    Here is the transmitter circuit. The coil L1 consists of 7 turns 22 SWG on a quarter inch plastic former with a tuning slug. The tuning slug is adjusted to tune the transmitter. Actual range on my prototype tuned from 81MHz to around 120MHz. The antennal is a few inches of wire. For receiving any FM receiver with 88-108Mhz frequency coverage iwll work fine. Good luck...dont forget the "Helped me" button.
