and a ground station receives and repeats the pulse back at another frequency. The aircraft receives the return pulse, and from the time it has taken to receive that return pulse, the distance to the ground station can be determined. The frequencies used are between 960 MHz and 1215 MHz, a...
Australia Standard Product sellpoints Portable Design:At just 300g and with a compact size, the Socotran FB-8811 is a lightweight, portable solution for on-the-go communication. Versatile Frequency Options:From FM to Air Band, this radio supports multiple frequency bands, catering to diverse com...
Rob from Frugal Radio has recently uploaded the next video in his airband monitoring series. In this video Rob explains various airband communications that can be received from the airport, and explains about needing to be in the line of sight of an airport in order to receive them. He goe...
The flight frequencies between Beijing and B&R countries are also very low. The direct flights between other Chinese cities to these B&R countries are even much fewer. In addition to the economic factors, the very restrictive bilateral ASAs between China and B&R countries are also to blame. For...

HRD-767 is equipped to receive AM, FM, and AIR frequencies, ensuring you stay connected to a wide range of broadcasts. The radio's sensitivity is impressive, capturing signals with precision, whether it's the latest news on AM or the latest hits on FM. The device's storage capacity is...
(Vaisala Battery Regulator QBR101) and the other for a 7 Ah backup battery. The mains power supply operates on universal AC inputs and frequencies (85 to 264 VAC and 47 to 440 Hz). The output voltage (15 VDC) is used to power the sensors as well as to charge the QBR101. The ...
The time taken to travel a given distance and the drop in SPL with distance. Frequency Attenuation The amount attenuated by each frequency band depends on temperature, humidity, and pressure. Only frequencies above 2kHz are significantly affected. The attenuation in dB takes into account the distan...
For two decades (1980–2000), several experiments were conducted with a clear choice for higher microwave frequencies (C- to Ku-bands) over longer wavelength (S- or L-band), and an ability to show about 5 dB contrast for a slick made with “light” fuel, and 10–15 dB contrast for ...
(480-520MHz). This extensive frequency range makes it suitable for various applications, from amateur radio to air band communication. The radio's ability to transmit and receive on six bands ensures that users have access to a broad spectrum of frequencies, enhancing their communication ...
