KD1JV Single Lever CW Trainer – $30
The KD1JV Single Lever CW Trainer kit was borne out of a user request. It combines Steve Weber’s CW Code Trainer with an onboard single lever paddle. It retains all of the trainers features, receiving random code along with the ability to practice sending code with an onboard single lever paddle similar to our KX series, external straight key, bug, and paddles for a compact trainer. Also, two people can practice sending and receiving to each other, one using the onboard paddle, and the other using an added paddle through the external port. As with the basic trainer, the right to left hand switching is a simple jumper settable option.
The standalone through hole kit has all the components except a user supplied CR2032 coin battery that mounts in the pcb battery holder. On a difficulty scale of 1 to 5, 5 being the most difficult, this is rated at 4, due to some small hardware. Assembly time is around 2-3 hours, depending on experience.
