The Es'hail-2 spectrum monitor is planned to be installed at Goonhilly Earth Station.

The hardware consists of a 1.3 Metre dish with a dual LNB. The separate horizontal and vertical feeds go to 2 Airspys which are connected to a Linux server.

The indoor LNB Power Unit has been constructed:

The GPS reference is a Leo Bodnar unit programmed to produced 10 MHz (for the Airspys) and 25 MHz (for the LNB, but not implemented yet). The settings for the reference to produce these 2 frequencies were not straightforward (as the 2 outputs on the Leo Bodnar unit need to be linked) but are here for reference:
