       | This is really neat, glad it made it to the front page! An
       | interesting next step could be: do it with a budget of less than
       | $x, gradually decreasing x each time.

       | buddies /colleagues
       | 
       | "What did you do this weekend?"
       | 
       | OP: "Drank some beer and sent some SMS through space"

         | Bouncing radio signals off of LEO satellite repeaters like the
         | ISS is surprisingly easy. All you need is a couple of
         | inexpensive handheld transceivers, an antenna (that you can
         | build) and an amateur radio license.

             | radio and your phone, and software to decode ham digital

             | for your area to take the required test.

             | * Yes I know most people think of baofeng but after owning
             | lots of cheap radios the best, far and away, is the
             | quansheng. They're very loud and clear with receive audio,
             | they are yaesu accessory compatible (iirc) and the older
             | ones are basically the Nokia handset of handheld radios.

               | Cool, thanks for the tip. I do have a baofeng that I use
               | for channel surfing here and there.

       | I read about something called othernet that allows receving those
       | messages with a parabolic antenna

         | The article describes APRS, a digital ham radio protocol.
         | Othernet is a broadcast system, nothing to do with ham radio.

             | Othernet is a relay for APRS messages which include
             | "outnet" in the text. A parabolic antenna/dish is not
             | required.
