I have studied radio astronomy before and it seemed like its all directed toward experts in field already. I&#39;m still fuzzy on the band and frequency deal. If its all microwave radiation, and in radio astronomy you are simply detecting the changes in magnitude, then why would you want to scan for UHF VHF FM dB and certain channels on each?

It is something that later in life, she will look back on and know she had a good attentive father.<br />I do have a few questions. I know this is an old posting but if you are still checking the messages I do hope you find this one. Did you ever hook the telescope to a PC? If so by what means? Have you thought about a way to graphically plot the signals you have received to compare them to other signals? <br /><br />Arial Firechildenothinghttps://www.blogger.com/profile/16113352883569936945noreply@blogger.comtag:blogger.com,1999:blog-9094742788006644220.post-54276472755442551552016-06-15T23_31_19.638-07_002016-06-15T23_31_19.638-07_00I&#39;m having the same problem...

They don&#39;t have the same kind of change in magnitude as celestial objects. That&#39;s my guess or to maybe go back and listen to old radio programs we transmitted billions of miles into space back in the 1950&#39;s?
