The Keyboard above is the KeyChron C1 is a mechanical clickty-clack keyboard. White keys backlit. Wired. I plugged it in to my 990 and it recognized it immediately and works seamlessly with the TS-990 CW Encoder/Decoder. I copy 22-24 wpm accurately. And didn’t think I’d use the decoder much. But after getting the keyboard it’s been fun to use. I switch between my Vibroplex Paddle and the KeyChron smoothly. It’s fun.
