Store description excerpt

SOTAMĀT is for licensed amateur radio operators (ham radio) who want to self-spot, self-alert, or send predefined SMS messages from remote areas where there is no cellular service, no internet, and who don't have access to a satellite communicator. If you enjoy Summits-On-The-Air (SOTA) or Parks-On-The-Air (POTA) this app is for you! The app encodes your commands into specially computed FT8/PSK31/RTTY messages composed of your callsign plus a suffix. Worldwide monitoring stations (skimmers) pick up your HF transmission and relay it to PSK Reporter, which forwards the message to the SOTAMĀT server where the suffix is decoded into a command. SOTAMĀT then connects to the official SOTA or POTA or SMS services to carry out your instructions. The amazing thing is that you don't need a computer (use your phone or tablet!) and you don't need special cables (use your phone's speaker directly into your HF radio's microphone input). The app not only computes the FT8/PSK/RTTY message, but can also generate FT8 audio directly (no computer needed, no dongles, no cables, and no sound-card interfaces!). See the https://SOTAmat.com web site for details. The app also comes with reference information on how to use additional 2-way services when you DO have internet, or cellular, or satellite service. The instructions can help you: * Post a Self-spot * Post a Self-alert * Get a list of recent spots * Get SOTA/POTA information (weather, callinfo, peak info, park info) * ...and more. Again, check out the web site for complete details: https://SOTAMAT.com
