[Milsurplus] WW2 Interception Receivers

[Ray Fantini]

Interesting to see the RAO represented in such large numbers, also why are there 11 RME preselectors and only 4 RME receivers? Wonder if they were used to improve performance of other receivers? Or maybe allow multiple receivers to operate on the same antenna by providing some isolation between but would think almost every receiver listed has fairly good isolation and plenty of gain.
