With one cut of a trace and one 10k resistor, you have 68-88mhz.
Reverse the modification for 30-54mhz.
European versions / North American versions - Pick your band!
30-54mhz is LOST with the 68-88mhz modification.

Took a bit to track this one down with help from Chris, the interfering transmitter was found and eliminated!
