What band is 70 MHz?
The 4-metre (70 MHz) band is an amateur radio band within the lower part of the very high frequency (VHF) band. The 4-metre band is unusual; very few countries outside of Europe have allocated amateur access.
What is the national calling frequency?
146.52 MHz
Across all of North America, the National Simplex Frequency (also referred to as the calling frequency) is 146.52 MHz. In areas that use 15-kHz channels, the adjacent channels are 146.535, 146.550, 146.565 MHz, etc.
How many GMRS channels are there?
GMRS is allotted 30 frequency channels in the vicinity of 462 MHz and 467 MHz. They are divided into 16 main channels and 14 interstitial channels.
What frequency is 80m?
3.5 MHz
The 80-meter or 3.5 MHz band is a band of radio frequencies allocated for amateur radio use, from 3.5 to 4.0 MHz in IARU Region 2 (consisting mostly of North and South America), and generally 3.5 to 3.8 or 3.9 MHz in Regions 1 and 3 (the rest of the world) respectively.
What is the 10-meter calling frequency?
The 10-meter band is a portion of the shortwave radio spectrum internationally allocated to amateur radio and amateur satellite use on a primary basis. The band consists of frequencies stretching from 28.000 to 29.700 MHz.
Which is the National calling frequency in North America?
Across all of North America, 446.000 MHz is the National Simplex Frequency (also referred to as the calling frequency). In most places, the channels immediately adjacent to 446.000 MHz are used as simplex frequencies, spaced by 25 kHz. This means that 445.925, 445.950, 445.975, 446.025, 446.050, 446.075 MHz are all valid simplex frequencies.
Which is the calling frequency for 70 cm FM?
K9ASE likes this. For FM it is 446.000 and that’s where the simplex action is. Your FT-60 does not automatically use -5 MHz offset. You have to program it for “simplex” operation without any offset. FM simplex is allowed on every band where voice communications is allowed. 432.100 MHz is the calling frequency for 70cm SSB, which your rig cannot do.
Which is the National calling frequency for FM simplex?
222.350 Mhz is the National FM simplex calling frequency. A 20 Khz spacing matrix is used on this band. Other frequencies in the 223.600 to 223.850 Mhz range are also used for FM simplex. 446.000 Mhz is the National FM simplex calling frequency. A 25 Khz spacing matrix is used on this band.
What kind of frequency is 446.000 MHz?
In most places, the channels immediately adjacent to 446.000 MHz are used as simplex frequencies, spaced by 25 kHz. This means that 445.925, 445.950, 445.975, 446.025, 446.050, 446.075 MHz are all valid simplex frequencies. But other areas have assigned these frequencies to repeater operation.
