Voice/audio communications between an aircraft and the ground are traditionally accomplished using radio telephony, broadcasting and receiving on: UHF; VHF; HF Frequencies immediately below HF are denoted medium frequency (MF), while the next band of higher frequencies … FM radio, two-way radios, and television broadcasts operate in this range. HF- High frequency (between 3 and 30 MHz) The HF band is a major part of the shortwave band of frequencies, so communication at these frequencies is often called shortwave radio. Please note that although the Guest Code allows applicants a reduced administration fee, all applicants are still required to go through the Clarion Events (DSEI event organiser) standard verification and payment process. The new VDL Mode 2 network, a high-speed and high-capacity digital communications network, provides over 20 times the message capacity than the older VHF mode 0/A subnetwork. communication, including a telephone call, drop-in visitors, distances between people, walls, and static on the radio. Except for local contacts, which are primarily made on Very High and Ultra High Frequencies (VHF and UHF), communicating between any two points on the earth rely primarily on high-frequency (HF) signals propagating through the ionosphere. Broadcasting and over-the-horizon radar also operate in these bands. Very High Frequency (VHF) Band TV Ch. VHF communication forms a very critical part for operation of an airport as it is the only means of communication between the Air Traffic Controller and VHF air-ground voice communication (VHF COM) systems. This ensures you’ll never be stuck when you need to contact others and that your investment in establishing an interconnected HF/VHF network pay for itself in improved communications accuracy.
