Frequency Allocation
See also: Amateur radio frequency allocationsThe International Telecommunications Union allocated the whole 500 kHz from 3.5 to 4 MHz to amateurs in the Americas, and 3.5 to 3.8 or 3.9 MHz to amateurs in other parts of the world. However, amateurs outside the Americas must share this useful piece of spectrum with other users, usually on a joint primary basis. As a result, authorities in the affected parts of the world restrict amateur allocations between 3.7 MHz and the top of the band.
Some allocations are as follows (in MHz):
- Argentina 3.500–3.750, 3.790–3.800
- Australia 3.500–3.700, 3.766–3.800 (Latter is a DX window for advanced licensees only)
- Canada 3.500–4.000
- Europe 3.500–3.800
- Japan 3.500–3.575, 3.599–3.612, 3.680–3.687, 3.702–3.716, 3.745–3.770, 3.791–3.805,
- New Zealand 3.500–3.900
- Russia 3.500–3.800
- United States 3.500–4.000

Famous quotes containing the word frequency:
“The frequency of personal questions grows in direct proportion to your increasing girth. . . . No one would ask a man such a personally invasive question as “Is your wife having natural childbirth or is she planning to be knocked out?” But someone might ask that of you. No matter how much you wish for privacy, your pregnancy is a public event to which everyone feels invited.”
—Jean Marzollo (20th century)
