It is used in radio, microwave and fiber-optical communication networks as a convenient measure of absolute power because of its capability to express both very large and very small values in a short form compared to dBW, which is referenced to one watt (1,000 mW). text/html 2019-10-31T08:55:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.plecko.hr/doku.php?id=amateurradio:europe_survivalist_channels&rev=1572508500&do=diff Europe Survivalist Channels PMR 446 PMR 466 Channel Frequency List (UHF-FM) This is the primary PMR channel set worldwide.
