3.5 MHz antenna and stepping motor project (2025/05/15) 
(Adjustment of the barycon is required to cover all bands from 3.5MHz to 3.8MHz)
So JG2TST MatsuiKOA GikenAfter consulting with the combatant, he suggested using a stepping motor to control

It was also sold by mail order in the Philippines.
ZK-SMC01andZK-SMC02
SMC01 has a different type of motor driver
SMC02 is a built-in motor driver type

manualZK-SMC01   ZK-SMC02
The fact that we can't guarantee the operation of the motor by connecting it 30 meters away from the SMC02 motor driver.
Place the TB6600 driver near the stepping motor.
JG2TST advised me to wire the signal line from SMC01 with twisted pair cable!

Does anyone know the current status of the stepper motor for the step IR antenna?
 
Or control from computer via UART
But I don't think it needs to be that complicated.
