In the few ROS 16 and ROS 1 tests that I have dome so far... ROS 16 seems similar to Olivia 8/1000 , good performance but perhaps a not quite as good as Olivia under QRM or deep fades.
ROS 1 , not as good as JT65A in very poor conditions. Anyone else have impressions, perhaps I am wrong... these are on-air impressions not lab tests. Andy K3UK
