WJ-8626A-4 Receiver and Controller

The WJ-8626A-4 receiver and controller is the HF heart of a WJ-9040 receiver system. It is a fully functioning HF receiver with sophisticated scanning functions. It came stock with one IF filter but many optional IF filters were available. It cannot operate without an EFR-100 frame containing a power supply and a frequency standard. The pinout for the connections to the EFR-100 can be found on the WJ-8626A-4 connections document.

I haven't had the good fortune to own one of these receivers yet. If any one would like to send well-illuminated, high resolution pictures of a WJ-8626A-4 receiver, I'd love to add them to this page. Or if you would like to part with one of these receives VERY reasonably... just contact me.

The inside of this radio is packed, especially with the preselector option installed. As with many Watkins Johnson receivers, a set of extender cards is vital for repair or alignment work.
