I have a P2 with Zenmuse gimbal, iOSD Mini and recently purchased a Black Pearl Rc801 FPV Diversity Monitor. I can connect the DJI 5.8GHZ video transmitter signal to the receiving unit attached to the monitor, and it displays the same frequency on Band E in Diversity Mode on the monitor. But when I just use the monitor (without the DJI receiving unit inputing the signal to it), the frequency on Band E on the monitor doesn't correlate with the same frequency coming from the transmitter. Example: Channel 4 (5645M) from the transmitter is either Channel 2 (5685M) or Channel 7 (5925M) on the monitor in Diversity Mode. I receive a clear picture on the monitor from the transmitter even though the frequencies aren't the same.
