4 m consultation in Belgium
Published on 12 December 2015 by Jean-Jacques ON7EQ

This to inform you that our national telecom authority (BIPT/IBPT) has launched on 4 December a public consulation regarding the possibility of expansion of our 4 m band (currenty 70.190 MHz- 70.4125 MHz) to 70,1125 MHz - 70,4125 MHz, all modes, and increase of power (25 W to 50 W), still on a secondary basis.

This in view of the fact that professional users are apparently no longer using this band segment.

As with previous similar public consultations, it can be expected that the band will be effectively be expanded within next weeks. A good thing - besides further widening the available segment for traffic - is that some planned beacon(s) could now be relocated as far as possible 'down the band' instead of somewhere in the upper segment.

Macedonia expands the 4 m allocation
Published on 17 August 2015 by Dave EI3IO
I have received an email from the President of the IARU Member Society in Macedonia which states that the Macedonian administration (Agency for Electronnic Coommunication) has granted a request by the Radio Amateur Union of the Republic of Macedonia for further access to the 70 MHz band and has approved the following frequencies: 70.000 MHz, 70.075 MHz, 70.125 MHz an 70.275 MHz for Radio Amateur activities on a secondary basis .... date of issue 01.08.2015 and date of expiry 31.12.2016. It is not quite clear how wide these allocations are. However if we refer to the Macedonian National Plan on pages 136 - 138 you will find that the band comprises 12.5 kHz channels in accordance with CEPT Recommendation T/R 25-08.

Gibraltar issues CEPT on 4 m
Published on 6 August 2015 by Jean-Jacques ON7EQ
I am pleased to announce that the Gibraltar Regulatory Authority (GRA) has from 5 August 2015 allowed operation on 70 MHz in ZB2 on a reciprocal basis (CEPT) and issued the first license as such to undersigned. Before, operation for visiting HAMS was only possible on 6 m and 2 m, but thanks to the efforts of the Gibraltar Amateur Radio Society (GARS), the bands have been extended to include 4 m and 70 cm. Still, the application for a temporary reciprocal license must be completed - see GRA website for more info.

Dave Court, EI3IO, and Member of the IARU Region 1 Executive Committee has written a 70 MHz initiative sent to all the member societies and their respective laison officers. It addressed the latest situation concerning the 4 m band, 69,9 MHZ to 70,5 MHz.

European Common (frequency) Allocation Table updated
Published on 10 July 2015 by Dave EI3IO
A new revised edition of ERC Report 25 - the European Common Allocation Table - has been published. The revision was approved at the WGFM#83 meeting and takes into account the latest Decisions made at the ECC#40 (30 June - 3 July 2015).

The new ECA inter alia includes a secondary allocation to the amateur service in the band 69.9 - 70.5 MHz.

However everyone should be aware that implementing the ECA is not mandatory on CEPT administrations. On the other hand the ECA can provide a regulatory mechanism for introducing

Published on 8 April 2015 by Bo OZ2M
Alex, LY3UM, writes that Lithuania amateurs have had access to the 4 m band since 10 February 2015. The permission dates back to the official gazette 2010, Nr. 108-5577 annex no. 1V-205, 2015-02-10, published in TAR, 2015-02-10, i. k. 2015 to 02041. Conditions are 70,240 MHz to 70,250 MHz, maximum EIRP 22 W, maximim SSB bandwidth 3 kHz and CW 500 Hz. Antenna height from the mid-point, not higher than 10 m from the ground.

Ofcom permits up to 71,5 MHz
Published on 3 April 2015 by Bo OZ2M

RSGB writes that Ofcom have agreed the use of 70.5 MHz to 71.5 MHz by radio amateurs for digital experimentation. Use will be permitted only via a Special Research Permit and further details of the application process will be published in due course.For information, the following conditions will apply:

  • Access to this part of the spectrum will be authorised under a Notice of Variation, time-limited to 12 months and available to Full Licence holders only.
  • Ofcom will retain the right to reallocate Amateur Radio spectrum at 70.5 – 71.5 MHz should there be a demand for this part of the spectrum from Business Radio and/or other or new services. In the event of this happening, Ofcom will not consult on this decision. However, Ofcom will provide Amateur Radio users with 12 months’ notice before such reassignment and this notice period will be publicised on the Ofcom website.
  • Amateur Radio use of this spectrum will be permitted on a non-protection, non-interference basis. Please note that if use is shown to cause interference, the spectrum will be removed with immediate effect
  • Permission will be subject to a geographical restriction and only granted for use in England, Guernsey, Isle of Man, Jersey, Northern Ireland and Wales. (There is legacy use of the spectrum by the Scottish Government which precludes licensing for Amateur Radio)

Note that in a similar manner to 146-147 MHz, international coordination is likely to be required as use must be compliant with the level published in the Harmonised Calculation Method (HCM) Agreement of +6 dBuV/m.
