Jump to navigation. The Citizens Band Radio Service CBRS is a private, two-way, short-distance voice communications service for personal or business activities of the general public.
It also may be used for voice paging. It is authorized 40 channels between The CB Service provides a service for short-distance communications by individuals and businesses. Over the years, changes occurred to the service such as adding additional channels; however, the purpose of the service has remained the same.
Anyone, regardless of age, can operate a CB station — except a foreign government, a representative of a foreign government, a federal government agency or someone who has received an FCC a cease-and-desist order that is still in effect. Anyone who is eligible may operate a CB station for personal or business use, in accordance with the rules. Part You may operate a CB transmitter at any location where the FCC regulates radio communications, subject to certain restrictions.
None of the CB channels are assigned for the exclusive use of any station. You must cooperate in the selection and use of the channels in order to make the most efficient use of them and to reduce the possibility of interference. If you use a CB station to transmit a message, you cannot talk with another station for more than 5 minutes continuously and then you must wait at least one minute before starting another communication.
About Rule Part 47 C. R, Part Channels There are 40 CB channels. Each CB channel is 10 kHz. The channel number and its frequency are: 1 There are several additional things to consider when using a CB device, including: You may not raise the power output of a CB transmitter. You may not attach a "linear," "linear amplifier" or any other type of power amplifier to your CB transmitter.
There are no height restrictions for antennas mounted on vehicles or for hand-held devices. For structures, the highest point of your antenna must not be more than 20 feet above the highest point of the building or tree on which it is mounted, or 60 feet above the ground.
There are lower height limits if your antenna structure is located within two miles of an airport. You may use an on-the-air pseudonym "handle" of your choosing. You must at all times and on all channels, give priority to emergency communications. Wireless Telecommunications. Wireless Services. Thursday, April 13,

Power Amplifiers
This is a list of vacuum tubes or thermionic valves , and low-pressure gas-filled tubes , or discharge tubes. Before the advent of semiconductor devices, thousands of tube types were used in consumer electronics. Many industrial, military or otherwise professional tubes were also produced. Only a few types are still used today, mainly in high-power, high-frequency applications. Receiving tubes have heaters or filaments intended for direct battery operation, parallel operation off a dedicated winding on a supply transformer, or series string operation on transformer-less sets. High-power RF power tubes are directly heated; the heater voltage must be much smaller than the signal voltage on the grid and is therefore in the In some valve part number series, the voltage class of the heater is given in the part number, and a similar valve might be available with several different heater voltage ratings. The system assigned numbers with the base form "1A21", and is therefore also referred to as the "1A21 system". Often designations that differed only in their initial numerals would be identical except for heater characteristics. A four-digit system was maintained by the EIA for special industrial, military and professional vacuum and gas-filled tubes, and all sorts of other devices requiring to be sealed off against the external atmosphere.

Currently there are -servers active, with -users and -MHz of radio spectrum. QRP, sunspots and radio propagations. Other than the military, amateur radio operators are the only users of the radio spectrum that are permitted to change frequency. I can tell you back in the early 80's 10 watt ssb mobiles were selling new for almost Note 5: Seven frequencies on a 20 kHz channel raster: Case CK.

You are making a mistake. I propose to discuss it.
When the essence comes - the questions “how to live will end, but this is a long development to go through.
Yes, really. And I have faced it. We can communicate on this theme.
I apologize, but, in my opinion, there is another way of solving the issue.
