FSK modulation/demodulation hardware 185Khz/131Khz

We are looking for someone to provide a tested hardware solution to modulate and demodulate a digital communication FSK in frequency: 185Khz for Mark (1) and 131Khz for Space (0).

This solution will be used to encode/decode a serial communication with 9600bps.

The solution must include hardware filters to reject noise.

We accept the bid only if you tell us in few words what kind of hardware solution you think about it.

DO NOT BID if you intend to ask money to be released in advance. Because we have problems in the past WE DO NOT release money in advance.

Skills: C Programming, Electrical Engineering, Electronics, Engineering, Microcontroller
