Broward's system is designed to modern standards meaning they increase site density to enable better in-building performance. For public safety grade radios, this is normally not an issue. But inexpensive consumer grade receivers are not designed to receive slightly out of time signaling, and the result is garbled or blanked out reception. One strategy is to desensitize the receiver by attaching an out-of-band / detuned antenna - a Comet baby comes to mind. This *might* work by eliminating some out-of-time signaling from more distant transmit sites, but the best solution has already been mentioned - buy a better-quality receiver designed to receive LSM simulcast systems. The Whistler radios are a bit more sensitive than others, which is a disadvantage when trying to receive LSM simulcast systems. But don't feel too bad: even public safety grade radios can suffer from "simulcast distortion" in certain areas, resulting in system operators changing transmit antenna heights, orientation, gains, etc.
