Hi Liborio,

on a test today with the 90cm dish static pointed for an 83 degree elevation pass, the time for the ISS signal to emerge and then disappear back into the spectrum analyser noise floor was about 24 seconds. There was about 20s above the threshold for demodulation, with the receiver taking about 5s to lock, giving up to about 15s of video, with a peak of D14. There was sufficient viewing angle and strength of signal to see pickup on the first side-lode of the antenna.

The antenna was aligned with very simple tools. Although for any particular location, one should take into account the local variation of Magnetic North versus True North.
