TRV 2nd generation in the feed point of 180cm Andrew solid dish
New contra weight arm and 15 kg weight on the end, two independent zero back slash gears for pointing system to the Moon.
Inside of TRV 24 GHz left, plate with TRV, LO and sequencer on right
Some details of opened TRV in the dish feed point
CS/G measuring -15,2dB to -18dB = 2,8dB ground noise
Sun measuring -8,6dB to -18,2dB = 9,6dB Sun noise
 

Power supply +6V / 20A - +Vd and -2,5V -Ug
