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.

1.1. General
  1. In Europe no input or output channels of NBFM repeaters shall be allowed to operate between 144 and 145 MHz.
  2. Except in the part of the band allocated to the Amateur Satellite Service it is not allowed to use input or output frequencies in the 145 MHz band for repeaters with input or output in other amateur bands (Miskolc-Tapolca 1978).
  3. No packet-radio networks will be set up in the 145 MHz band and no access from the 145 MHz band to networks on other bands will be allowed.

    It is recognised that in some parts of Region 1 the introduction of packet-radio may require the use of access frequencies in the 144-146 MHz band for a limited time (Düsseldorf 1989).

    Note. The parts of Region 1 meant are those parts with low amateur population and/or those at the periphery of the Region, where exceptions can be tolerated as these do not harm the orderly use of the band in the parts of Region 1 where there is a greater pressure on the available spectrum space. In the latter part of the Region the second paragraph of the footnote should never be used to justify ignoring the first part for a considerable time.

  4. Beacons, irrespective of their ERP, will have to be situated in the beacon part of the band.
1.2. Footnotes
  1. Telegraphy is permitted over the whole band, but preferably not in the beacon band; Telegraphy exclusive between 144.035-144.150 MHz.
  2. Within IARU Region 1 the frequencies for beacons with an ERP of more than 50 Watts are coordinated by the IARU Region 1 Beacon Coordinator; the frequencies for beacons with and ERP of 10 Watts or more shall be communicated to the Beacon Coordinator.

    If there is a real need for more repeater channels, 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:

    For FM repeater and simplex operation in the 144 to 146 MHz band IARU Region 1 will change to a genuine 12.5 kHz channel spacing system.

    Furthermore in Tel Aviv, 1996 it was decided that societies shall promote the use of the 12.5 kHz channel spacing standard for NBFM channels in order to effectively implement the 12.5 kHz system .

  3. Established simplex frequencies on repeater output channels may be retained.
  4. 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.

    This decision was re-confirmed at the IARU Region 1 Conference in Brighton (1981).

  5. No unmanned stations shall use the all-mode segment (Tel Aviv 1996)
  6. Network stations shall only operate in the part of the 145 MHz band allocated to Digital Communications and will be permitted only for a limited time. Such network stations should also have access ports on other VHF/UHF or Microwave bands and should not use the 144 MHz band to forward traffic to other network stations. In view of the time limitation the set-up of new network stations is not encouraged (De Haan, 1993).

    Unmanned packet radio stations are only allowed in the segment 144.800-144.990 MHz. Outside of this segment the signal level produced by those stations shall be not larger than 60 dB below the carrier level (measured in a 12 kHz bandwidth). Any other unmanned packet radio and digital access points must cease operation not later than 31 December 1997.(Tel Aviv 1996).

  7. Footnote withdrawn.
  8. For a limited period - and never longer than novice stations in The Netherlands are only allowed to use SSB between 144.440 and 144.490 MHz - SSB and Telegraphy operations are also allowed in the 144.440/144.490 MHz part of the beacon band. (Tel Aviv 1996 )
  9. All beacons shall move from the 144.850/144.990 MHz segment to the 144.400/144.490 MHz segment before 1 July 1997. When coordinating frequencies the beacon coordinator shall try to place well known DX-beacons in the 144.400-144.440 MHz segment. Digital communications shall not use the 144.850/144.990 MHz segment before 1 July 1997. (Tel Aviv 1996 )

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.

At the meeting of the VHF/UHF/Microwaves Committee in Vienna, March 1992, the following recommendation was adopted:

Societies should publish the use of 144.140-144.160 MHz as an alternative for EME operation. The results of this test should be monitored with the aim of incorporating this segment as EME alternative into the Usage part of the bandplan if successful. 2.1. Footnotes
  1. Publicity should be given to the usage of frequencies around 144.600 MHz by RTTY stations, in order to keep these frequencies clear from other traffic and to avoid interference with those RTTY stations.
  2. Footnote withdrawn.
  3. For NBFM 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).
  4. In order to make worldwide operation of the SAREX project possible in its nitial phase and facilitating the conversion towards use of higher frequency bands, the frequency 144.490 MHz can be used for uplink communication using NBFM for a limited period but not after 1 October 1999 (Tel Aviv 1996).
