Thanks to the hospitality of the DARC we will be able to have an informal C5 meeting. Not only for the VHF managers but all HAM’s who are interested in the work of IARU-R1 VHF & up matters.
After a small introduction about the way of working of C5 we will have an open discussion. This could be useful to prepare for the Vienna interim meeting in 2016.
This meeting will take place on Saturday June 27th from 15.00 until 16.30 in Room A (5th floor) in the administrative building. You have to leave the exhibition(don’t forget to get your stamp) and walk to the administrative building.
We would appreciate that you inform your members about this meeting and are looking forward to seeing you there.

New spectrum for digital experiments in UK
02-04-2015
Submitted by: ON4AVJ
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:Use will be permitted only via a Special Research Permit and further details of the application process will be published in due course.
- 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 – 71.5MHz 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 146-147MHz, international coordination is likely to be required as use must be compliant with the level published in the Harmonised Calculation Method (HCM) Agreement of +6dBuV/m.

70 MHz in Malta
18-02-2015
Submitted by: ON4AVJ
The 70,0 MHz - 70,5 MHz band has been allocated to Amateur Radio use on secondary basis and included in the National Frequency Plan as published by the Malta Communications Authority (MCA) on 13 Feb 2015.
There are quite a few local stations interested in being active on 4 m.
23cm EME Contest

Hi All,

I enjoyed the nice activity on 23 cm during the ARRL contest, with a good mix of CW, JT and SSB QSOs. Many stations were contacted on both CW and JT modes. After cleaning all the dupes, I ended with a total of 86 QSOs and 33 multipliers. Was also very pleased to QSO the PZ5EME expedition on 13 and 23 cm for a new DXCC and first from ON. Their 1.5 m dish was producing a very nice signal on both bands!

Activation of 3A
02-08-2014
Submitted by: ON4AVJ
From August 11 to August 13 3A/ON7EQ will be active from 3A in JN33 square.
Activation on MS 70 Mhz (and possibly 50 MHz if there is interest) next Perseid shower, August 12th & 13th, is hereby confirmed.
Hans ON5AEN, who has MS experience on 2m, will join to operate the station. More info - like frequencies, sequences etc… - will be released later via ON4KST chat.
Meanwhile, already prepared some theoretical range prediction. As you are probably aware, Monaco is only 3 kms long and 300m wide, with mountains towards the north and west… not the best place for a low take-off angle! According to our spot where we have chosen to set up the station and the theoretical models, we expect a range like depicted on the map - as you can see ON will be ideally within reach!
73 and looking forward to cu in MS!

UK Amateurs Losing Access to Part of 2.3 GHz and 3.4 GHz Bands
15-04-2014
Submitted by: ON4AVJ
UK telecommunications regulator Ofcom has announced that it’s ending Amateur Radio access to significant portions of the 2.3 and 3.4 GHz bands.
The action, announced on April 7, came in the wake of a year-long “consultation” — a rule making proceeding — that involved the release by the Ministry of Defence of 40 MHz of spectrum at 2.3 GHz and 150 MHz of spectrum at 3.4 GHz. Amateur Radio is secondary on the bands.
Amateur Radio will lose privileges on frequencies in the two bands that overlap with spectrum that Ofcom plans to award for “new civil uses” — 2350 to 2390 MHz and 3410 to 3475 MHz. The announcement gives radio amateurs at least 12 months’ notice, but radio amateurs must comply immediately with procedures to avoid interfering with other users; ham radio occupants of 2310 to 2350 MHz will have to register their use and provide details to Ofcom.
Amateur Radio will retain access to the adjacent bands, but Ofcom has put procedures in place to remove even those frequencies from Amateur Radio access, if necessary in the future. Ofcom said earlier this year that with military and other government use of the 2.3 and 3.4 GHz spectrum ending, “we believe an award of the spectrum for high power use is likely to deliver greater benefit to UK consumers and citizens than continued amateur use.” Ofcom was required by the Ministry of Defence to adequately protect its systems from Amateur Radio interference in both the released spectrum and in adjacent bands.
“The MoD’s plans are part of a government commitment to release 500 MHz of spectrum by 2020,” Ofcom explained in its order. “This commitment to opening up spectrum for new civil uses is based on growing demand from UK consumers for spectrum-hungry devices such as smartphones and tablets.” Ofcom said that use of mobile data devices more than doubled in the 18 months leading up to January 2012. “Indeed, the 2.3 and 3.4 GHz bands are identified in Ofcom’s ‘mobile data strategy’ as having the potential to support even better mobile data services for citizens and consumers in the coming years,” the regulator said.
Ofcom said it was making 2300 to 2302 MHz available for amateur use, but licensees first must obtain a Notice of Variation to their licenses. Hams in the US have secondary access to 2300 to 2310 MHz, 2390 to 2450 MHz, and 3300 to 3500 MHz. — Thanks to RSGB, Ofcom
