6 meter tape

from Wikipedia, the free encyclopedia

The 6-meter band is the frequency range from 50  MHz to 52 MHz (Europe) or from 50 MHz to 54 MHz (USA), which is used by various radio services, mostly military radio services in addition to broadcasting (which is being phased out). The amateur radio service has a secondary status in Europe or is tolerated. In the United States are radio remote controls also operated in 6-meter band; 10 channels are assigned for this.

6 meter amateur band

The 6-meter amateur band is 2 MHz or 4 MHz wide depending on the ITU region and, due to its wavelength, has both shortwave properties and typical VHF properties. There are reflections on the ionosphere possible both via the E layer and via the F-layer , here, however, almost exclusively in the sunspot maximum .

Band plan

The band plan recommended by the amateur radio associations and therefore not legally binding is as follows:

Frequency range use
50.000-50.100 MHz Max. permissible bandwidth: 500 Hz
  • 50,000–50,080 radio beacons (please no transmission)
  • 50.030 Beginning of the area permitted in Germany
  • 50.090 CW activity center
50,100-50,500 MHz Max. permissible bandwidth: 2700 Hz
  • 50,100–50,130 DX windows (wide area connections)
  • 50.110 intercontinental calling frequency
  • 50,150 SSB activity center
  • 50,285 cross-band working frequencies
  • 50,305 PSK31 Activity Center
  • 50,310-50,320 earth-moon-earth
  • 50,320-50,380 Meteor Scatter CW and SSB
50,500-51,000 MHz Max. permissible bandwidth: 2700 Hz
51,000-52,000 MHz Max. permissible bandwidth: 6000 Hz
  • 51,210–51,390 repeater input ( uplink )
  • 51,410-51,590 FM
  • 51.810-51.990 repeater output ( downlink )

Situation in Germany

Since August 25, 2006, new regulations apply to operation on the 6 m amateur radio band (frequency range 50.08–51.0 MHz). Radio operation is only permitted from fixed, officially registered amateur radio stations of certificate class A. Only the modulation types J3E and A1A (SSB and CW) with a power of 25 W ERP may be used. Only horizontal antenna polarization is allowed. The radio station must be reachable by phone during radio operation. A log book is to be kept.

Allocations were given for three radio beacons in Germany, all of which transmit on 50.483 MHz with a time offset in A1A.

Callsign place QTH locator Transmission power antenna
DF0ANN Moritzberg JN59PL 2 watts Horizontal loop (omni)
DB0HGW Greifswald JO64QC 2 watts Magnetic Loop (omni)
DB0DUB Gangelt JO31AA 1 watt Horizontal HALO (omni)

On May 23, 2013, the German Federal Network Agency released the 50.03–51.0 MHz band on a test basis until December 31, 2013 for all modes of operation with a maximum bandwidth of 12 kHz and published it with Official Gazette No. 2/2014 in Communication No. 96/2014 extended until December 31, 2014.

As of January 1, 2015, the Federal Network Agency also changed the permissible transmission power to 25 W PEP. An operational report was not submitted. This change was only valid until December 31, 2015.

This was followed by an extension to December 31, 2016 in Communication No. 34/2016 and further until December 31, 2017 in Communication No. 1700/2016. [outdated]

In November 2017 there was an amendment to Communication No. 1700/2016 of the Federal Network Agency. The use of the previously tolerated section 50.03–50.08 MHz became an official part of the Frequency Ordinance.

The Federal Network Agency has been implementing the WRC19 results for the first time since May 6, 2020. In short:

  • 50.0–50.4 MHz with max. 750 W PEP transmission power for class A, max. 100 W PEP transmission power for class E.
  • in the rest of the band for both class A and class E 25 W PEP transmission power
  • all transmission types with max. 12 kHz bandwidth
  • only horizontal antenna polarization
  • Contest operations are now allowed all year round

Situation in Austria

The maximum permissible transmission power in Austria is 100 W; Mobile operation is also allowed. The restriction on the operating mode was lifted and unmanned transmitters (repeaters, beacons and digipeaters) were allowed.

Since the Jauerling transmitter on Volume I is no longer in operation, all restrictions imposed to protect this transmitter have been lifted from November 12, 2008 by the amendment to the Amateur Radio Ordinance.
