anyone has experienced these two diversity receiver, Wisycom MCR 42 and Lectrosonic srb?
the wisy seems to be a real true diversity on both channels but I don't understand if lectro is same,

Lectrosonics says that their SRb receiver is diversity only in the single-channel mode.

here is said Dual channel SmartDiversityTM reception • Single channel Ratio Diversity reception

It looks like they tried to give you the best of both worlds...

When RATIO DIVERSITY is enabled, both receivers are combined to pick up the same transmitter, so the Main Window will display a single audio channel as shown here.
