upgrade ROT2PROG
after 5 months of using the controller, the relay switched on permanently and the rotator spun around and around
I was also bothered by the constant clicking of the relays when watching satellites
that's why I bought this controller to control two motors
and replaced the 4 relays that control both motors
original controller diagram
and a conceptual wiring diagram with the controller
I also put filters in front of the motor outputs
I disconnected resistors R10,R11,R12,R13 and connected the signals from the processor to the controller

Arrow SAT antenna on tripod version 1
this was the first version
- light and not very stable tripod
- the tripod head broke
- there was interference with the tripod especially in the 70cm band
recommendations for the next version : more massive tripod, placing the antenna in front of the tripod to avoid interference with the antenna
