The WSPR Beacon App is made to send WSPR signals using your Android smartphone/tablet as a signal source. All you have to do is use the audio out of it and pair it with the audio in of your rig (and set it to VOX). All you ha to do is: 1) Set your CALLSIGN 2) Set your LOCATOR or press the GPS button and have the app automatically calculate it based on your position. Please allow a few seconds for the GPS to get exact coordinates. 3) Set the POWER LEVEL so that it matches your rig output power 4) Select the BAND (optional). This is only to have handy the frequency value to set on the rig. 5) Set the TX FRAMING. This allows you to set how ofter the WSPR will be sent. By default the WSPR is sent only once. 6) Select the BASE FREQUENCY. It can go from 1400Hz to 1600Hz and by default it is 1500Hz 7) Press START The app will wait for the next frame start before sending. So you only have to make sure that the clock of your smartphone/tablet is synced. By pressing the REPORTS button you can monitor, filter and share reception reports. By pressing the MAP button, the app will open the related WSPRnet.org map page to view reports.
