We are linking to the Alan W2AEW video above. Alan's YouTube channel is an excellent resource for ham radio, test and measurement, as well as other electronics knowledge. The video gave us the idea to check the CW keyer speeds on our most expensive rig and our lowest price rig. It seemed like a good excuse to use the Liquid Instruments Moku:Lab oscilloscope, plus we were curious.

We won't explain the method, Alan W2AEW does a great job with that in the video. One different is we used the audio output for our delta(t) measurement.

Here are our results:
We haven't seen the same RBN vs. Rig WPM speed different as Alan pointed out and the table helps explain why. Sure, the numbers are 'off' at the 25WPM test, but we seldom operate at those CW speeds.
