There is a company called Optoelectronics that markets a radio reciever
called the Interceptor. This is a broad band (several hundred MHz)
device designed to lock on to the most powerful signal around,
regardless of frequency. As supplied, it only has a rubber duck
antenna, but a broadband, directional antenna (Log Periodic?) could be
attached. There are AM and FM versions that output audio and a version
called the Scout that controls a scanner. These could have outboard
devices hung on to them to decode digital signals, record the
conversation ... all for less than $1000.
