Ah, right... that explains my confusion.
Ron (M0WSN) has a Canadian WS9 remote receiver and has been looking for the connecting cable for a while. I thought I'd solved that problem with a box of WS52 bits from an auction, but the connectors are from the units and not the case.
I found the connectors and they're off a sender, so no use to man nor beast.

(Also spent some time rummaging through the EMERs, trying to find the Remote Receiver section, with no success.)
