If you're in the vicinity of the transmitter, or on the "beam path" of the transmitter (bearing to the receiver), you might pick it up. Most STL's and RPU's are very directional.
The received fidelity won't be that great...most scanners are built to receive the narrow-band FM signals (3 kHz wide) used by police and fire service radios rather than the 150 kHz-wide signals of full-fidelity transmission systems.
Also, STL systems are increasingly being converted to digital transmissions, which may stop the scanner passing through but will sound like static.
Hope that helps.
Later...
