After the dish controller rebuild, now I’m updating the X-Band downconverter.
One question that rounds over my mind some times is how good is the phase noise of the Ma/Com brick that I’m using in the downconverter as local oscillator. The last year I was puchase in eBay a nice Ferranti brick oscillator.

Phase noise test

The two units are locked to a 10MHz rubidium reference. After some tests and tuning, the Ferranti beats the Ma/Com, it is much clear:
