The Satran rotator follows the birds but one great problem:

If I transmitting on 2m or 70cm the rotator goes immediatly into the wrong direction. Also on low power - 1 to 5W - with my FT-817. The antenna I'm using ist an Arrow antenna 3 elements on 2 meter and 7 elements on 70 cm.

Did anyone try transmitting with success to Leo satellites? If yes with which antennas?

Hope for Help..

Really nice setup!

The radio noise issue is resolved in firmware 1.2, which removes the PWM motor control and accounts for EMI to the sensors. MK2 firmware and instructions on updating will be posted on the downloads page shortly.
