Re: 21MHz satellite interference from planet Jupiter ???



Dear William and others.

Just last week i was in Westerbork were the dutch radio telescope is.
The first thing i saw was a sign that told everybody : cellphone`s
forbidden.
There was a second plate that told that anny other transmitting equipent
was considdered a cellphone aswel.

I can tell you , if you show one of the astonomers there a TH-79 he will
proberbly go `into orbit`.
At Westerbork they are doing a new experiment now ,
they are listening at 180 and 460 MHZ............

Radio telescope`s and Ham`s don`t go well together.
Until the HAM builds his own disch / radio telescope.......
