Wireless Telephone Bug

Here's a neat little project that will allow you to monitor your phone line as soon as your phone is off hook. You can use a regular FM broadcast band radio to monitor the conversation. Just remember, it may not be legal to do this. You should check with local law authorities to determine the legal implications if you use this device.
