The beam controller project with a two line version by Stan LZ2STO at top and my latest four line version below. The latter now has a hardware clock.

Computer driven if required the box is fully capable without help.

Chris VK5MC is a friend of many years. This is his well made 10 metre dish for 1296Mhz EME. Following a QTH change, it became his second EME dish. The small room is his TX and converter hut.

Chris’s dish was the reason the VK5DJ beam controller project came into being. Chris uses AS5040s for direction information.
