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.
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.
ADSBee 1090: An Open-Source ADS-B Receiver Built for Modern Aviation Tracking
ADSBee 1090 is an open-source ADS-B receiver that decodes 1090 MHz aircraft transponder signals using RP2040 PIO — a low-power standalone aviation tracker with Wi-Fi data streaming.
Building an FT8 Digital Interface – Dive into Digital Modes
This FT8 digital interface connects a computer to a transceiver using a USB sound card, audio transformers, and optocoupler-based PTT control. It enables clean audio exchange and safe isolation, allowing reliable weak-signal digital communication modes like FT8 through proper level control and synchronization.
