It is the first place to check online for knowledge about almost 'anything' or any topic. It usually has many 'Reference Links' at the bottom for more in depth gathering.
Some places to search for further information and new sites: (General Web searches)
Another place to grab information that we use a lot:
- REDDITS sub Search Site ~ Enter a search topic and view lots of up-to-date information from users around the globe. People talk about their projects, ask questions and participate in open conversations about many, many topics. Try it out, we think this is a great source.

Miscellaneous Sites of Interest:
Introducing some 'General Information' on 'Other Topics'... future work will be directed into a method to better index our SARA's Links page. {April, 2016} On a web page this large... remember that the search box at the top is a great friend to you.

- Heavens-Above Site ~ find the ISS location.
SARA's Hint: Click 'Unnamed' in the top right to get to select location screen. Type your postal code (zip) into 'Enter place to search for' and click Search. Scroll down and click Update. You'll now be back on the homepage; under Satellites/ 10-day predictions, click ISS. For 'Passes to include', select 'all' (this adds in 'daylight passes'.
The table will now show lists the times of the upcoming ISS passes for your location. The Alt value under 'Highest point' is the maximum elevation of the pass above the horizon; 90 would mean it goes directly overhead. Passes with higher maximum elevation will give better results than lower ones. Clicking on any row in the table shows the sky chart for that pass. Imagine holding that picture above your head and aligning it with the compass directions. The line shows the flight path of the ISS and this is useful for roughly positioning your antenna. It can also be useful to look at the 'Ground track' (see link in top right). Plan ahead and set up your ground station with time to spare before the ISS flies over.
See MagPi Issue #80, page 62 for a detailed article on capturing SSTV from the ISS. MagPi Issue #80. From Byron, MI and 'Amateur Radio Satelites' you can check for radio satelites that Hams use for communication. Click on the satellite name for more details.
