I wonder if any have experimented with magnets hovering over
reed relays to act as the contacts of a Morse Key, possibly on

The reason i ask is the difficulty of excising noise on the dot contact
of the bug key I made a couple of years ago.

I bought a Ten-Tec keyer at a rally, which used electromagnets instead
of springs.

I hated it - ended up flogging it on ebay and got a Katsumi instead.
