The Es'hail-2 spectrum monitor has been installed at Goonhilly Earth Station, but is awaiting completion of the network connection before the installation is operational.
RF
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:
