  • 4.4.1 Notes: BANDPLAN
  • The following notes are part of the officially adopted IARU Region 1 bandplan, and all member societies should strongly promote adherence to the recommendations made in these notes.
  • General:
  • i.
  • In Europe no input or output channels of telephony repeaters shall be allowed to operate between 144.000 and 144.794 MHz.
  • ii.
  • Except in the part of the band allocated to the Amateur Satellite Service and the linear transponders it is not allowed to use input-or output frequencies in the 145 MHz band for repeaters with in-or output in other amateur bands (Miskolc-Tapolca 1978, San Marino 2002).
  • iii.
  • Deleted (Vienna 2016)
  • Footnotes:
  • a.
  • Telegraphy is permitted over the whole band, except in the beacon band; Telegraphy exclusive between 144.000 -144.110 MHz. (except satellite output downlink to earth)
  • b.
  • Refer to Beacons Chapter for coordination of beacons in the beacon sub-band Section-11
  • c.
  • For technical standards on FM and repeaters see section-8
  • If there is a real need for more repeater channels (see section-10), it is recommended that Societies or Repeater Groups consider setting up a repeater system on the higher frequency band(s).
  • Further to this subject the following recommendation was adopted in. De Haan, 1993:
  • Deleted (Vienna 2016) For the numbering of FM telephony channels, see annex 2 to this section.
  • d.
  • Established simplex frequencies on repeater output channels may be retained.
  • e.
  • In view of the important public relations aspect of amateur satellite activities, it was decided at the IARU Region 1 Conference in Miskolc Tapolca (1978) that:
  • i.
  • AMSAT will be allowed to use the band 145.8 -146.0 MHz for amateur satellite activity.
  • ii.
  • This decision was re-confirmed at the IARU Region 1 Conference in Brighton (1981).
  • iii.
  • see also footnote p
  • f.
  • No unmanned stations shall use the all-mode segment, except for linear transponders and ARDF beacons. (Tel Aviv 1996, San Marino 2002)
  • g.
  • Attention is drawn to section 1.1. point iii of these Bandplan notes!
  • h.
  • Unmanned packet radio stations and digital access points are allowed in the segment 144.800 -144.9625 MHz, provided they are fully compatible with 12.5kHz channel spacing. Any other unmanned packet radio outside of this frequency range must cease operation.
  • i.
  • This segment is for simplex use only with no Digital Voice gateways. Embedded data traffic is allowed along with digital voice. Digital Voice users should check that the channel is not in use by FM.
  • j.
  • Amateur Satellite Linear Transponder down-links. Subject to agreement with Region-2 and Region-3
  • 4.4.2 Notes: Usage
  • The following notes are referring to the Usage column in the bandplan. As already set out in the introduction to section IIc, in the right amateur spirit operators should take notice of these agreements which are made for operating convenience, but no right to reserved frequencies can be derived from a mention in the Usage column or from the following notes.
  • Footnotes:
  • k.
  • Not used
  • l.
  • Not used
  • m.
  • See procedures set out in section 7.4
  • n.
  • Deleted (Varna 2014)
  • o.
  • Not used
  • p.
  • For FM voice communications with special stations like manned spacecraft it is recommended to use 145.200 MHz for simplex operation or 145.200/145.800 MHz for split-channel operation (Vienna 1995/Tel Aviv 1996).
  • q.
  • It is recognised that in the IARU Region 1 rules for the Championships in Amateur Radio Direction Finding (ARDF) competitions, the frequencies for the unmanned beacons are in the segment 144.500 – 144.900 MHz. These beacons run low power and are on the air only during ARDF events. (Davos 2005)
  • r.
  • No transmission shall be made below 144,0025 MHz* (Varna 2014) *so that a necessary guard band is provided at the bottom edge
  • 4.4.3 National usage notes
  • Some countries have existing use at:
  • •
  • 144.660-144.690 Linear Transponder Inputs
  • •
  • 144.630-144.660 Linear Transponder Outputs
  • IARU
