APRS is a fascinating technology that allows for the transmission and reception of digital data over As shown in the table, the ARRL 2 Meter amateur band plan supports a wide variety of radio operation. At a one hertz record rate, more than 2 hours of position data can be logged. There are many challenges opposing the use of WSPR on VHF and this page details my battles with them all. Mike-sounds ambitious and doable. Communicating through radio frequency oscillation within an electromagnetic field (commonly called radio communications) is an amazing technology that we often take for granted in the modern world where smart phones, Wi-Fi, satellite television, GPS, RFID cards, and even garage door openers implement radio comm all around us. The problem is, that I wasn’t able to decode the AFSK transmission using either multimon-ng or qtmm decoder sw. 00 Choose from economical 2M devices or step up to digital handhelds. Powered by 6xAA Alkaline, Lithium Poly , or automotive power (12-16V) batteries. 0 is one of the most affordable, smallest, lightest, powerful and open source APRS trackers available. I was looking at spending upto £200 as this is all I could realistically spare at the moment. HAB-1 flew to 91,650 ft in about 3 hours and 10 minutes. I also have a Byonics Micro-Trak RTG that uses a Micro-Trak VHF Antenna V3 antenna. The inclusion of a transmitter makes these dedicated devices a bit expensive, so if you would prefer to use an existing transceiver you could use an APRS TNC and a GPS and hook it into the microphone and speaker sockets. 95 Type: 2M/70cm I have been thinking, off and on, about how to make a very low power 2m FM transmitter in order to get weather data into my APRS system wirelessly. Can anyone suggest a 2M FM transmitter, 5 to 10 watts output, to replace the handheld? I don't need a mobile transceiver, just a TLDR: I'm looking for a very lightweight ( < 50 g) and cheap ( < $25) 2-meter transmitter that stacks directly on top of an associated microcontroller, similar to the ones that exist for 33 cm and 70 cm. Propagation. TinyTrak APRS Controllers The TinyTrak3Plus and TinyTrak4 are APRS controllers which can be connected between a GPS and any 2-meter radio to transmit a location to the APRS network. In amateur radio communication, the 2m frequency band holds special significance due to its well-balanced characteristics between communication range and penetration capability. The Importance of the 2m Frequency Band: The 2m frequency band refers to the 2-meter band in the amateur radio spectrum, typically ranging from 144 MHz to 148 MHz. If it makes a difference I live downunder in VK-land, I occasionally travel outside of normal 2m APRS coverage, and had a random thought that it might be fun to bounce packets off APRS sats and the ISS. It integrates a GPS, TNC (terminal node controller) and 5 watt RF transmitter into a single circuit board. My objective is to use the SX1278 as an 2m APRS transmitter for a school pico balloon project. TinyTrak3Plus The TinyTrak3Plus is a simple, popular way to build an APRS tracker.
