Just a quick note:
You don't exactly want to jam a particular frequency, you want to disable a radio, that is presumably in a fixed location and quite close.
Instead of transmitting over the commercial broadcast frequency, it would be more effective, and less likely to cause spill-over problems, if you went after the IF frequency. With a highly directional antenna, you would be able to target the radio, and there shouldn't be any problem with spill-over to other devices.
Of course, it might be easier just to call up the radio station and put in requests for what you want to hear. :)
