| #405: Using TinySA Ultra to measure keyer speed of a Kenwood TS-890S transceiver This video shows how to measure the keyer speed of a CW transmitter using a TinySA Ultra in Zero Span mode with a trigger. The formulas are simple: WPM = 1.2/unit_length and unit_length = 1.2/WPM ...where: WPM = Words Per Minute unit_length = time duration of a "dit" The rig is a Kenwood TS-890S, and the measurement verified that the WPM setting is accurate (unlike some rigs shown in my previous video, linked below) https://www.youtube.com/watch?v=gaEm8TiRQnQ |
