DIY Antennas, QRP, SDR & Ham Radio Projects from VU3DXR
A technical guide to receiving and decoding signals from NOAA weather satellites. Explore DIY antenna projects—including the 137 MHz V-dipole and QFH designs—tailored for APT (Automatic Picture Transmission) reception. This section provides step-by-step tutorials on using RTL-SDR receivers, software like WXtoImg and NOAA-APT, and tracking polar-orbiting satellites to capture real-time weather imagery from space at your own home station
By DXR News Desk August 13, 2025 The National Oceanic and Atmospheric Administration (NOAA) is nearing the conclusion of its long-standing Polar Operational Environmental Satellites (POES) program, a constellation that has provided critical weather and environmental data for decades. As of today, the remaining satellites—NOAA-15 and NOAA-19—are on the cusp of decommissioning, marking the transition […]
NOAA-15 & NOAA-19 shutdown in Aug 2025 ends APT signals. Hobbyists: explore Meteor-M2, GOES, & SDR skills to keep decoding weather satellites data.
NOAA-15 is scheduled for decommissioning on August 12, 2025, with NOAA-19 following a week later on August 19, 2025, have exceeded their primary mission lives
Modified simple horizontal V antenna This antenna is little modified version of antenna designed by Adam 9A4QV for noaa/METEOR Weather sat reception. Adams antenna is based on a very simple linearly polarized dipole, which makes construction almost trivial. I tried his antenna and found that practical difficulties in finding choc block terminals. Chock block terminals are not strong enough […]
Beautiful images received from NOAA19 weather satellite with experimental V dipole antenna Location – Krishnagiri, Tamilnadu, India Receiving Hardware – RTL SDR with experimental v dipole antenna. Receiving NOAA-19 Automatic Picture Transmission (APT) signals presents an exciting opportunity for radio enthusiasts to explore satellite communications while experimenting with antenna designs. The V-dipole antenna configuration offers […]
NOAA19 weather satellite reception with experimental v dipole antenna Date – 18.01.2022 Location – Krishnagiri, Tamilnadu, India Receiving Hardware – RTL SDR with experimental v dipole antenna. NOAA 18 and NOAA 19 weather satellites provide free accessible weather data continuously through Automatic Picture Transmission at 137.9125 MHz and 137.1000 MHz frequencies. RTL-SDR TUTORIAL: RECEIVING NOAA […]
DIY – 137 Mhz V-dipole antenna for weather satellites reception D.Prabakaran VU3DXR A V-dipole for NOAA weather satellites on 137 MHz has been published by 9A4QV and it seems to get very good results. The designed antenna works at frequency 137 Mhz with omnidirectional radiation pattern. The length of the each leg should include the […]
