I want to learn CW, but i have a problem with my MB1. When i put in the jack for straight key or padle the radio start send dit in the speed what the transceiver is set up for. When i press breakin and press the key is start TX and when i release the key is continue to TX.
Have you checked to see if the wiring for the jack conforms to the diagram on page 19 of the MB1 user manual? If gnd, dot , dash are incorrect or if there is a short due to using a stereo jack, this could be a reason for the issue.
