+===== Android =====
+The easiest way to start playing SSTV is to install [[https://play.google.com/store/apps/details?id=xdsopl.robot36 |Robot36]] to receive and (optionally) [[https://play.google.com/store/apps/details?id=om.sstvencoder |SSTV Encoder]] to send.
+To test this off the air, use a phone with SSTV Encoder to "transmit" the picture as sound via the speakers, while a second phone with Robot36 listens and decodes the image.
+To decode SSTV transmitted over the air, do the same thing: have your phone with Robot36 listen to the radio speaker and you'll see the image load.
+===== Computer =====
+The previous method is the most basic and is subject to noise from the environment.  A better way of receiving and transmitting is to send the audio from the radio straight to a computer.
+With the [[howto:signalink |SignaLink]] already installed and configured, the only other step is to install a program like [[https://hamsoft.ca/pages/mmsstv.php |MMSSTV]]

+===== ISS =====
+From time to time, the International Space Station transmits pictures on 145.800 MHz.  To find out where the ISS is, the Android app [[https://play.google.com/store/apps/details?id=uk.me.g4dpz.HamSatDroid |AmsatDroid]] is excellent.  More information about SSTV from the ISS, can be found on [[https://amsat-uk.org/beginners/iss-sstv/ |amsat-uk.org]].
