Those photos don't come through for me. Did you mark them for public sharing? 73 Martin AA6E |

Aha. It looks like a "crystal calibrator" device that might be installed as an option in an older receiver, but probably that's not it if the crystal is 3.53 MHz. I suspect it's TV-related. B&K (note NOT B&W!) made a range of TV alignment generators, and this could have been a piece of one of those. Hopefully, someone will recognize the specific product. 73 Martin AA6E |

My mistake Martin. It is stamped B&K. I believe it to be associated with some sort of TV test gear too. Looks like it was never used by the look of the clean wire ends. Only paid $2.50 for it. I opened it up and made a schematic diagram of how its wired. It might make a nice little QRP rig with a few additional modifications. Thanks for your reply. |
