For those of us not fortunate enough to own an Elecraft KX series or KH1, I have a project that is a quick and dirty way to anchor your magnetic key to a clipboard. All that is needed is a fender washer from the hardware store and a hot glue gun. The best (ie, most magnetic) washer was the one marked ‘ALB’, but just take your key with you and try out what they have. If you find one you have to slide off, that’s getting there.
1) Affix the washer to the clipboard with hot glue. I recommend heating the washer with a heat gun first so you have time to reposition it if desired.
2) Put the washer on your key, and the glue on the washer. Position and press, and avoid moving it around while the glue cools (about a minute). If you do need to reposition it, remove the key, heat with the heat gun, replace the key and reposition.
I’m right handed so the key is on the right so I don’t hit it when I’m logging.
In case you are wondering about the chip in the carrier, I am working on a cordless interface between the key and a CW decoder for the IC-705. The plan is it will use the IC-705’s bluetooth connection to send audio to a Pi Pico for decoding, and then it will send back dits and dahs to the keyer. It should be able to be powered by a lightweight 3.7v rechargeable battery. This is in the early stage, but is showing promise.
