Hi guys, first time posting so please be gentle , I have a metal detector that transmitts its signals to cordless headphones using a choice of 2 channels, ch1 is 433.575Mhz and ch2 is 434.075Mhz, what i want to do is make a "probe", basically its a hand held metal detector that helps with pinpointing a target in the hole however i want it to transmit the signal on either ch1 or ch2 so the headphones pick it up, i've seen these tx transmitters you can get that can be programmed to work on 433.575Mhz and 434.075Mhz, the question is how would i get it to transmit audio distance only has to be 10 feet or so, when i read about them all i see is talk about data rate etc and no mention of audio, any help would be much appreciated.

Cheers Harry
