Radio Astronomy Experiments with a 5.6m Dish.
Brief description of my Radio Astronomy set-up.
All equipment was designed and built from scratch.
I use my 5.6m dish antena at several frequency bands (but one at a time).
All the downconverters where made to have a 144MHz (EME converters) or
137MHz (RA converters). This way was possible to use just one design
of radiometer to cope with experiments
at any of the bands I can setup a feed and converter for.
Take a look of some observations I made with this system.

A total power radiometer follows the converter output:

RF gain, DC gain, integration time and DC offset can be set manually.
