Transmitter power is limited to 25 watts, giving them a range of about 100 kilometres (62 mi; 54 nmi). Marine VHF radio equipment is installed on all large ships and most seagoing small craft. It is also used, with slightly different regulation, on rivers and lakes.
Very high frequency (VHF) is the ITU designation [1] [2] [3] for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high ...
The allocation limits amateur stations to 15 watts effective isotropic radiated power (EIRP); however some locations will be permit up to 25 W EIRP. 40 metres – 7.000–7.300 MHz – 42.83–41.51 m actual; Considered the most reliable all-season long distance band. Popular for DX at night, 40 metres is also reliable for medium distance ...
Comparable to the American SCR-508 tank radio, which covered a similar frequency range (20-27.9 MHz) at 25 watts and the SCR-608 artillery variant (which operated in the 27-38.9 MHz frequency band) The major difference between German Army tank sets and US Army tank and artillery sets was the American use of FM for the high-HF/low-VHF bands.

A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
An ICOM IC-7300 Radio Tuned to the 20 Meter Band. The ICOM IC-7300 is a multimode 6 meter, 4 meter (ITU Region 1 only) and HF base station amateur radio transceiver. [1] The IC-7300 was announced to the public at the Japan Ham Fair in 2015. [2] The radio has 100 watts output on CW, SSB, and FM modulations and 25 watts of output in AM. [3]
The SINCGARS operates on any of 2320 channels between 30 and 88 megahertz (MHz) with a channel separation of 25 kilohertz (kHz). It accepts either digital or analog inputs and superimposes the signal onto a radio frequency (RF) carrier wave. In FH mode, the input changes frequency about 100 times per second over portions of the tactical VHF-FM ...
