It took just one night — February 16, 2026, 22:47 UTC — for a small group of Italian radio amateurs to change the digital HF landscape forever. FT2, developed by Martino Merola IU8LMC of ARI Caserta, compresses a full ham radio QSO to as little as seven seconds, running four times faster than FT8 and twice as fast as FT4. Within two weeks, it had been spotted on PSKReporter from dozens of countries, spawned two incompatible software implementations, and ignited a fierce debate about open-source ethics, automation, and the soul of amateur radio digital operating. This is the complete story of FT2 — the mode, the schism, and what comes next.

The FT2 Schism: When a New Digital Mode Split in Two
In February 2026, amateur radio gained its fastest weak-signal digital mode — and immediately fractured it. FT2 promised ~4-second QSOs and contest-level throughput, but within days of its first on-air tests it split into two incompatible implementations. Here’s the full story of the “FT2 war,” why it happened, and what it means for HF operators everywhere.
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
Baofeng UV-5R Mini: Compact Dual-Band Powerhouse
The Baofeng UV-5R Mini brings USB-C charging and Bluetooth to the classic UV-5R platform. While it excels in portability, it faces significant hurdles in Airband reception and UI quirks.
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 Digital Mode: Speed King With Serious Growing Pains
FT2 promises ultra‑fast QSOs with 3.8‑second cycles and up to 240 contacts per hour, but early adopters are divided. This in‑depth report analyzes FT2’s technical trade‑offs, including its weaker –12 dB sensitivity, very tight ±50 ms clock requirement, Windows‑only Decodium client, and limited award support. It also compiles global feedback from Facebook, Reddit, YouTube, blogs, and WhatsApp groups—ranging from contesters who love the speed to operators who see FT2 as risky, unnecessary, or too fragile for weak‑signal DX.
Beginner’s Guide to HF SSTV Setup with SSB Transceivers
Slow Scan Television (SSTV) is a fascinating mode that allows you to send and receive still images over HF radio using your SSB transceiver. The uBITX and similar homebrew/commercial SSB radios are excellent platforms for SSTV operation. This comprehensive guide will walk you through the complete setup process.
The Complete Guide to HF SSTV: From History to Your First Transmission
Slow Scan Television is a method of transmitting still images over radio using audio frequency tones. The term “slow scan” distinguishes it from conventional fast-scan television (like broadcast TV), which requires much wider bandwidth.
Reverse Beacon Network: The Ultimate Guide for Ham Radio Operators
The Reverse Beacon Network represents one of the most significant technological advances in amateur radio during the past two decades. By providing instant, objective feedback about your transmissions, the system empowers operators to understand their stations better, optimize their performance, and make informed decisions about when and where to operate. Whether you are testing a new antenna, chasing DX, competing in contests, or simply exploring the bands, the RBN adds a dimension of awareness that was previously impossible.
Practical guide to receiving HF weather fax WEFAX / Radiofax
Weather Facsimile—commonly known as WEFAX, HF-FAX, or Radiofax—is easily one of the most rewarding niches in the shortwave hobby. There is a certain “magic” in tuning your receiver to a scheduled frequency and watching a high-resolution synoptic chart or satellite image slowly materialize on your screen, line by line, over several minutes.
