Thanks for a very informative video.

7:48 the center cross bearings actually adjust two things, they can center the top and bottom contacts one to the other sideways and they also adjust the bearing drag that you do well explained.

Yes I agree. May be I didn’t explain well enough that the bearing adjusters centre the lever and hence the contacts as well as the “drag” . Thanks for highlighting.

I received a DM-901 as a Christmas gift today. It came with no instructions for its features. I'd like to learn CW, and the person who bought me the key had no idea that it had voice and beep features. Without a manual, I have no idea what to do to make these features work. Since I don't know CW, I don't want to connect it to my radio just for practice. If you have suggestions for me and my issue, it's appreciated.

I confess I don't know the DM901, but it looks like a straight morse key that can be used with an oscillator or a radio transmitter. It is just like a switch that opens and closes, making and breaking a circuit.

Nice! I have seen youtubers use those and it looks like a pretty good key! Good luck!

I have a chinese DM-901 which is a battery powered beeper, cheap and nasty circuit, purely functional. They could'nt even be bothered to install a proper square wave generator ! However, i only bought it for the pure morse key, not the beeper function. You need something like a preamp and headphones with volume control to make use of the beeper. It's got a 3 pin 2.4 mm jack for its output. Hope that helps.
