Hi Steve: WORST CASE... if you attempt DIVERSITY reception (during which both RXs are supposed to be receiving on the same (exact) frequency, you will probably note a slight 'beat' between the two received signals. This will usually present itself as a (usually slow) side-to-side (assuming a 2-speaker configuration) movement of the perceived received signal at a rate determined by the amount of frequency mismatch between the two filters... usually on the order of 3Hz or less... often 1Hz or less.
