[hpsdr] So I ordered an atlas, preparation is in order

[Tim O'Rourke]

I also have a hot air station, the only issue for me is getting solder paste that is fresh eneough to keep a while before getting too stiff to use. If used greater quanities of the paste it would not be a issue.
The paste seems to have limited life even with cold storage.

Is there any real way, other than starting to plug everything else in to test that I didn't goof up? I'll probably have this guy done long before I start ordering more.

Never done surface mount other than tapping boards for test leads and voltage modifications (gotta love nvidia video cards). I'm ordering a real soldering station, instead of my little 15 watt rad shack special, but not sure if it will be here in time.
