A New Ghost Box Hack: The Sangean ATS-909
This hack comes courtesy of a reader named Mike who came up with this hack. It is easy to disable the mute which allows for the scan to become a functional ghost box.
The instructions, according to Mike, are as follows:
1st: Download the service manual for the ATS-909
2nd: Study board layout, and schematics located at the bottom of PDF
3rd: Scroll down the PDF file to the schematics. Find the connector(s) and pin(s) labeled “Mute.” This is the wire to clip. BLACK wire.
4th: Open the radio and locate the corresponding jumper wire set that connects top and bottom PC boards. Black wire labeled “MUTE” at the connector on bottom board, lower right. Clip it.
5th: Press/hold one of the scan buttons (FM band) and there is no longer a mute function.
These radios are not the cheapest radios on the market, but we all know that Sangean makes a quality radio. If you are interested in doing this hack for yourself, you can buy the Sangean ATS-909 here.
