33 centimeter tape

from Wikipedia, the free encyclopedia

The frequency range from 902 to 928  MHz is called the 33-centimeter band . The name is derived from the approximate wavelength of this frequency range. In some countries amateur radio is allowed in this frequency range , but not in Europe, because here this frequency range is assigned to various mobile radio services .

Everyone's radio

Some time ago there was already a radio for everyone in the 933/934 MHz band .

Switzerland

2 x 39 speech channels and 2 organization channels with automatic call switching without infrastructure were permitted. When there is a call, the devices meet on the organization channel. The calling device searches for a channel that appears to be free based on the field strength and transmits a desired channel on the organization channel. No base or repeater stations are required for this.

Manual channel operation is also possible in the "upper" band, but not in the "lower" band.
