Of all the Amateur Radio frequency allocations, the 1.81 - 2.0 Mhz band has the longest wavelength (160 metres) and is known as Top Band. For many years this band was shared with shipping and falls within what was known as the Trawler Band. The band was also occupied for many years by the Long Range Airborne Navigation system: "LORAN A" .
The band is interesting being characterised by short range use during daylight, but with the possibility of very long range at night, especially during sunspot minima. For many years it was the primary band for mobile operation.
