GM4JMU Shortened Dipole Antenna: Compact Performance for HF Bands

GM4JMU Shortened Dipole Antenna: Compact Performance for HF Bands: This design is a classic example of a coil-loaded dipole, a method that uses lumped-constant inductors to electrically resonate a physically short antenna. By inserting these coils symmetrically into the antenna’s radiating elements, we introduce the necessary inductance to tune the system to the 40-meter band, even though the overall wire length is significantly reduced.

Getting Started with AIS: Track Ships from Your Shack with a RTL-SDR

Getting Started with AIS: Track Ships from Your Shack with a RTL-SDR : The Automatic Identification System (AIS) is a VHF radio-based collision-avoidance protocol that virtually every commercial, passenger, and large recreational vessel in the world is required to carry. Since 2004, the International Maritime Organization (IMO) has mandated AIS transponders on all ships of 300 GT or more engaged in international voyages, all cargo ships of 500 GT or more on domestic routes, and all passenger ships regardless of size.
