Ah, but does it make a good cup of tea and dip sheep?

I like your Dragons....

ref Radio Telescope,

I already have the basis of Radio Telescope, but am tempted to go down the
22GHz route as I already have two 22GHz receivers (from a satellite downlink
station). I plan to build a short baseline interferometer on a E-W azis and
beamed South but with full declination control. Keeping the baseline short
and using common local oscillators means that I won't have any phase errors
to worry about.

However, the downside is that 22Ghz is very near to a major water absorbtion
line, which means high attenuation. But, there is also a primary Radio
Astronomy Spectrum Allocation in this area, which *should* mean an RF quiet
area and so should not be too susceptible interference.. one can but hope.

Um. yes? ;-)

I'd guessed the radio bit from the G0CZD though.

hmm.   Microwaves eh?

you dont want to join in my 10GHz Radio Astronomy project do you?

Do not meddle in the affairs of Dragons, for you are tasty and good with
ketchup.
