Boatanchors: Jackson Harbor Grid Block Keying Adapter Kit, Circa 1998

12.00

With the increasing popularity of vintage transmitter operation, here’s a Grid Block Keying Adapter that allows CW operators who love their solid-state keyers to use them with many tube-based rigs with low negative voltage keying. It was produced in the late 1990s by Jackson Harbor Press with the caveat that it will not work with rigs having cathode keying (positive high voltage). If you have a vintage, commercially-manufactured transmitter or transceiver and aren’t sure how it is keyed (grid block vs. cathode), Google the name and brand of the rig. The specifications should tell you which keying circuitry is in your radio. The kit offered here is in its original packaging and includes documentation. It is suitable for beginners with some soldering experience. This version of the Jackson Harbor Press Grid Block Keying Adapter is believed to be no longer in production.
