What is the 40 meter calling frequency?

The 70-centimeter or 440 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use. The ITU amateur radio allocation is from 430 to 440 MHz; however, some countries, such as the United States, allocate hams 420 to 450 MHz.

The most popular use of CTCSS for simplex around here seems to be on the “family band” as most of these FB low power transceivers have tones built in. We have extensive use of simplex frequencies in my area (Victoria B.C.) for local safety communications on two meters, but CTCSS is never used for this .

Simplex – In the amateur radio context, simplex operation means the radio stations are communicating with each other directly, on the same frequency . Both stations take turns transmitting and receiving on the same frequency with no repeater or other device in between.

Simplex communication is a communication channel that sends information in one direction only . The International Telecommunication Union definition is a communications channel that operates in one direction at a time, but that may be reversible; this is termed half duplex in other contexts.

The most common VHF radios are basic FM mobile or handheld transceivers. These radios usually tune the entire 2M band from 144 MHz to 148 MHz in 5 kHz steps. … What Frequency Do I Use on 2 meters? 144.000-144.100CW (Continuous Wave, Morse Code)146.400-146.595FM Simplex (National Simplex Frequency =146.52 MHz)146.610-147.390FM Repeater OutputsWhat Frequency Do I Use on 2 meters? – Ham Radio School www.hamradioschool.com › post › what-frequency-do-i-use-on-2-meters
