As Los Angeles battles ongoing wildfires, tens of thousands face displacement. Recovery begins now, but long-term healing will take years, requiring community support and resources for rebuilding and emotional care. Here are some key steps and resources to help.
EME communication requires specialized equipment, including: High-gain antennas: Large, directional antennas, such as Yagi, parabolic dish, or array antennas, are necessary to focus the transmitted signal towards the Moon and capture the weak reflected signals.
They are particularly useful for low-power (QRP) operation and are used for DXing and Earth-Moon-Earth (EME) communication. JT65 and JT9 transmissions are slower than FT8 and FT4, but they offer greater sensitivity and better performance in weak-signal conditions.
Parabolic antennas are highly directional and are commonly used for high-frequency (microwave) communication, including satellite and EME (Earth-Moon-Earth) communication. To use a directional antenna effectively, follow these steps:
Earth-Moon-Earth (EME) Communication: Also known as moonbounce, EME communication is a mode where radio signals are bounced off the Moon’s surface and received back on Earth. This technique allows for long-distance communication between amateur radio operators on opposite sides of the Earth.
Simplex (direct) communication, digital modes, and weak signal work such as moonbounce (EME) or meteor scatter are also possible on this band. 70 centimeters (420-450 MHz): This UHF band is another popular choice for local FM communication, often used in conjunction with the 2-meter band.
Moonbounce (EME): Earth-Moon-Earth (EME) communication, or moonbounce, is a technique used by advanced amateur radio operators to bounce signals off the Moon’s surface and back to Earth. This allows for communication between operators on opposite sides of the globe, although it requires specialized equipment and precise antenna pointing.
