Tired of lost packets and weak signals in your ADS-B setup? STREAM1090 introduces a paradigm shift in demodulation, moving away from fragile preamble detection to a robust, CRC-validated bit-streaming approach that extracts more data from the noise.
Reception
The Reception category focuses on pulling weak signals out of the noise using smart antennas, low‑noise front‑ends, and modern SDR tools. It covers topics such as HF broadcast listening, weather satellite reception on 137 MHz, ADS‑B and aircraft tracking, WebSDR resources across India and Asia, and general SWL (shortwave listening) techniques. You’ll find practical antenna designs, preamplifier ideas, and receiver setups that improve copy without requiring huge towers or expensive commercial equipment.
The Silent Revolution: DRM+ Radio in the FM Bands
Analog FM is hitting its limits. Enter DRM+, the open-standard digital revolution that brings CD-quality audio, multimedia data, and emergency alerts to the 88–108 MHz band. Explore the technology and global adoption of 2026.
Receive DRM with HDSDR and DREAM Decoder Using RTL-SDR
This guide explains DRM basics, SDR devices, and a complete working setup using HDSDR and DREAM. Build a DRM receiver step by step while learning how digital radio works on SDR platforms.
Small Magnetic Loop: A Guide to the Foldable 40m-17m Stealth Antenna
Struggling with limited space or high local noise? The Magnetic Loop antenna is the ultimate “stealth” solution for hams. We dive deep into the PA0WIT design, featuring a 1/5 ratio Faraday loop for a perfect 1.1 SWR and peak performance from 7MHz to 18MHz.
Getting Started with AIS: Track Ships from Your Shack with a RTL-SDR
Every vessel larger than 300 gross tons is legally required to broadcast its identity, position, speed, and heading every few seconds on VHF radio. With a $25 RTL-SDR dongle and free software, you can receive, decode, and map those live transmissions from your living room — no licence required, no nautical background needed. This guide walks you through the AIS standard, the hardware and software stack, antenna options, and how to contribute your decoded data to global ship-tracking networks.
V32: The Mystery Spy Radio Station Broadcasting in Farsi — and Nobody Knows Who’s Running It
On the day Israel and the United States launched their first strikes against Iran, a mysterious shortwave radio station flickered to life on 7910 kHz. It hasn’t gone silent since. Broadcasting streams of numbers in Farsi — a Cold War spy radio technique that was thought to be fading from use — the signal has now been logged from Europe to North America. Radio amateurs have given it a name: V32
Sporadic E Propagation: The Science Behind Long-Distance FM Radio Reception
Discover the science behind Sporadic E propagation — the ionospheric phenomenon that lets FM radio signals travel 2,000+ km. Includes antenna tips, best seasons, monitoring tools, and DX listening tricks
Join the 8-Meter Experiment: Monitor FT8 on 40.680 MHz with WQ2XDM
Join FCC-licensed WQ2XDM’s 8-meter experiment on 40.680 MHz FT8 and 70 MHz WSPR/FT8. Monitor 24/7 digital modes, decode Sporadic-E signals with SDR, and contribute real propagation data for future band access. Schedules, tips inside.
FT2: The Fastest Digital Mode in Amateur Radio
Developed by Martino Merola, IU8LMC, from the ARI Caserta team in Italy, FT2 is a genuinely operational new digital mode — not vaporware, not a proposal. It was publicly verified on 16 February 2026, with dozens of real QSOs logged on 40m and 80m bands.
FT2 – A New Digital Mode Hams Are Starting To Spot
FT2 is an emerging weak‑signal amateur radio mode now visible on PSKReporter, offering hams another option next to FT8 and FT4 for HF QSOs and propagation monitoring
