Remote Unit MR-9B (for Bendix RA-10DB Rx) wiring info wanted
Hi,
Does anyone have a type MR-9B Bendix Remote Control Unit for a Bendix RA 10DB WW2 aircraft receiver (circa 1942-44) for sale? I'm restoring both units as a volunteer for the Canadian Air & Space Museum, Toronto - Lancaster bomber restoration project, see http://casmuseum.org/about.shtml If you don't want to part with it, I could use some good macro pictures of the wiring as the MR-9B unit we have was butchered sometime in the last 60 years and I'm trying to rewire the pots and band switch. I have the schematic so making some progress but a spare unit or some pics would help. As many of you know, the RA-10DB receiver and the MR-9B remote are totally integrated so the Rx can't be operated stand-alone. I suppose I could build a complete remote unit emulator but I'd rather not! Besides, it won't look right. BTW, we also have to rebuild the cables. Does anyone have the right Canon plugs? Present plan is to emulate with separate female pin connectors to the Remote Unit and Rx sockets, two short stubs of multiway wire and two pairs of modern multiway plugs and sockets. Any better ideas? Thanks for all replies, Cheers, Roger PS. Of course, post replies but email any pics to me at "analogdino at (ta-boy) rogers dot(ty-as- they) com(e)", suitably decoded. Visible address is fake for anti- spam. Thanks again. |

To date, no posts and no email! I have managed to re-connect all the wires but three.. and I think I'm getting close to them! In a few days it will be "plug and play", I hope! Also hoping the "new" 65 yeaer old bandswitch motor is not stuck... Cheers, Roger |

In about the late 1940's the publisher of CQ magazine published a series of paperback surplus handbooks on converting surplus radio gear. These had schematics and details of many fairly common equipments. Its even possible that some public libraries may have them. -- Richard Knoppow Los Angeles WB6KBL |

Looks like they will be most helpful in sorting out our unit. Cheers, Roger |
