![]() ![]() More talks from the conference can be found on this YouTube playlist. The talk slides can be found here, and the video is shown below. They can then be accessed on a PC by the CW Skimmer program which decodes the received CW signals, and then logs it online on the reverse beacon network's website. This allows multiple RTL-SDR dongles to emulate a multi-band HPSDR receiver over Ethernet. The RTL-SDR dongles run on a Raspberry Pi which runs the rtl_hpsdr software. Alternatively any decoding program based on audio can be used. His talk was about setting up a VHF+ reverse beacon network monitoring station, using multiple RTL-SDR dongles for monitoring. SDR Rx/Tx software for Airspy, Airspy HF+, BladeRF, HackRF, LimeSDR, PlutoSDR, RTL-SDR. It is currently working mostly with CW (morse code) stations, and mostly on HF, although it is expanding to VHF+ as explained below.ĭuring October, John Ackermann (N8UR) did a talk at the "Microwave Update 2018" conference held in Dayton, Ohio. The data is made public on the internet and this allows amateur radio operators to easily determine overall propagation conditions. The Reverse Beacon Network is a project that monitors the amateur radio bands by using volunteer stations to continuously and autonomously collect data on what/when stations are being received, and how good the signal is. Estimated Lightsail-2 Viewing Range Lightsail-2 Deployed Clicking on the 10-day predictions button will give you pass predictions for your location. You can see the solar sail's current location at N2YO. ![]() So only locations with a latitude between 42 and -42 degrees will have a chance at receiving it. One difficulty in receiving Lightsail-2 is that it is in an orbit inclination of only 24 degrees. There is also an AX.25 telemetry data transmission, however although the beacon structure is available we are not aware of any publicly available decoding software. This beacon should be able to be received with a handheld amateur radio 70cm Yagi and any radio such as an RTL-SDR. On board Lightsail-2 is a radio which is transmitting it's morse code beacon "WM9XPA" every 45 seconds at 437.025 MHz. Lightsail-2 is still undergoing testing, so it has not yet deployed it's solar sail, but recent updates indicate that it is healthy. A solar sail is a type of spacecraft that uses a large metallic foil to create propulsion via photons from the sun hitting it. Lightsail-2 is a solar sail experiment which successfully launched on a Space-X Falcon Heavy on 25 June, and was released into orbit on July 2nd.
