Very high frequency omnidirectional range (VOR) is a type of shortrange radio navigation system for aircraft, enabling aircraft with a receiving unit to determine its position and stay on course by receiving radio signals transmitted by a network of fixed ground radio uses frequencies in the very high frequency (VHF) band from to MHz.

My hopes were high for the IC9700. The IC9700 has many of the features of the IC7300 but in a 3band VHF/UHF transceiver. As well as the colour touchscreen display and a very comprehensive settings menus, the transceiver also has realtime spectrum scope and a waterfall display. The transceiver covers the 2m, 70cm and 23cm bands as standard.

In some extended overwater areas, VHF voice coverage facilitates the capability to communie with ATC at all times, in airspace beyond 50 NM, or even 100 NM, from the nearest shore. For these areas, the ground infrastructure allows maintaining a continuous watch on the appropriate ATC frequency (being able to communie with ATC at all times) using VHF radios.

A collection of repeaters connected together provide mobile portable radio users coverage over an extremely wide area, thus extending the range of communiions. Technically speaking A radio repeater is a combination of a radio receiver and a radio transmitter that receives a signal and retransmits it, so that twoway radio signals can cover longer distances.
