In diversity mode, the main and sub RX synthesizers are guaranteed to be phase-locked to each other if the crystal filters selected for main and sub both have exactly the same frequency offset. The offset for all 8-pole filters is 0.00. The offset for 5-pole filters varies, and can be ordered in matched sets for main/sub.
