Hi. Not many posts have originated from areas of low population which are real DX to most stations. I would like to address the current band plan and virtually all proposals for change! I would also like to add another important key issue, ITU Region 1 does NOT have a 50 MHz international allocation to the amateur service, except by a footnote to Article 5 of the ITU Radio Regulations to some named countries in Southern Africa. The current status of the band in Region 1 in individual countries and in sub-regions such as European CEPT countries has been attained by bodies such as the UKSMG lobbying their regulatory authorities for access to the band. There are still a number of countries without such access, for example in my present location, my neighbours in Saudi Arabia and UAE do not currently have 50 MHz facilities granted in their licences. That leads me to the next issue that if 50 MHz is indeed first and foremost a DX band, which is up to 4 MHz wide in ITU Regions 2 and 3, and in Region 1 is from 200 kHz to 4 MHz wide, dependent on location, why is most conventional DX activity squashed into less spectrum than is available in 3.5 MHz, 10 MHz, 18 MHz and 24 MHz. Now bearing in mind that the radio spectrum is a scarce resource what are we generally trying to achieve in the band and how should we advise our friends in countries without the band to approach their regulatory authorities for access? In all honesty is any more than 500 kHz really required? In A9 when the band is open with Es or F2, it is probably as busy as 14 MHz, with everyone squashed into just over 200 kHz, some of which is barred within the band-plan. I cannot find a frequency sometimes where I can work split with a wide QSX or a narrow QSX. If the majority interest is DX working in 6m, then please consider a band plan that facilitates such activities. There are many modes of operation (many with minority interests) which could be accommodated towards the HF end of the band. Some may argue that this is often secondary spectrum but if it's hardly used, what is the point of having it? With a band the size of 6m, I would at least like to see the lower 500 kHz used to provide for conventional main-stream amateur communications and interests. As the last 40 years of my professional career has been in spectrum management I would then not feel uneasy that a band which is up to to 4 MHz in width, is for more than 99% of time under-utilised. And when it does get busy it seems strange that it cannot be fully utilised because of a plan which does not promote the efficient use of all the spectrum which is available for amateur exploitation. Can we not have some imaginative thinking which seeks to at least address this basic enigma. Such thinking might entail different uses at different times of the year or at different times of the solar cycle or indeed during a major propagation event. Many of us know that 70 MHz also offers semi-magical properties on occasions, I am certain we can find a better way of using 50.200 to 54.000 MHz! Best 73s and see you in the pile-ups. Dave A92IO

A brief note that the Region-1 conference is closer and that all the papers
themselves are now available to download/comment

from [www.iaru-r1.org]
and [www.iaru2011.org.za]

The future of beacons and 6m band plans does feature in the C5 VHF/Microwave committee papers inc a quite a detailed new plan from DARC

enjoy the read

Murray G6JYB

PS Am aware 6m is not an ITU allocation yet in Region-1 but it is rising in IARU priorities

Well it would seem that 3 things have occurred from the latest lack of debate on the forum. Either everybody doesnt really give a damn - beside the few that have expressed thier views her, or people are have had there say and expressed their views - and dont need to say any more. Or finally they dont have any confidence that the matter will be debated in IARU in a fit manner ( no disrespect to those attending) so little pint in expressing any views
Obsrvation fron Chat pages - debate did take place there - mixed views of course - but one view does come through time after time - all the CW is condensed into a narrow band and stations are finding little or no room to qso - so calls for the beacon qrg to move are abundant it would seem - and thats the ONLY point of contention I can see.

Ken, I think the difficulty is that many keep flogging their own hobby horse or want to protect their own fiefdom. There is enough bandwidth to accommodate all, it only requires compromise and a bit of vision.

CW users want more bandwidth while the fragmented SSB allocation is bordering on insane. The 6 metre population is growing at such a rate and it (regrettably?) has to be recognised that SSB is the primary mode for new licencees CW being largely an irrelevance, at least initially.

Unless specialist users are prepared to relinquish traditional frequencies and embrace change it will remain a mess.

In my opinion the EME segment and other MGM modes should move considerably up the band to avoid compression at the bottom end.

My concern is that unless a logical and credible coordinated band plan can be agreed then voluntary adherence becomes less likely.

We should also remember that any changes that are eventually made to the bandplan (2018?) will likely be in force for a decade or two when many “OT” ops, whose values and technical expertise will be very greatly missed, have gone to join Marconi and Tesla in that great Radio Club in the Sky. I don’t want membership of that club quite yet, but just think of all the amazing conversations and revelations!

I look forward to meeting you at the BBQ.

David

Its a pity I cant post a graphical copy of it here because I hope you will like the result but the latest IARU-R1 VHF Newsletter carries the detail that came out of the Sun City (USKA chaired) 6m working group. No doubt it will be formally on the web shortly

The overall band plan for 50.00-50.50MHz starts asap (which means Jan 1st in practice) with a transition period for the old and new beacons running till 2014 (the latter will be based on a synchronised scheme that was first outlined in Six news but now needs defining in more detail, whilst others not in the scheme move as previously planned).

Many thanks to Murray for the work he has put into this.  Although not completely 'done and dusted' the plan below is likely to form the future of Region 1's plan for 6m.  

DV = Digital Voice   
NOTES ON THE 50 - 52 MHz BANDPLAN 
1. IARU REGION 1 BANDPLAN 
This bandplan, first adopted at the IARU Region 1 Conference in Torremolinos (1990) and revised at the 1996 Tel Aviv conference, the 2002 San Marino Conference, and the 2011 Sun City Conference is recommended for use in those countries in the European part of Region 1 which allow amateurs to operate in this part of the radio spectrum. In many countries in the African part of Region 1 (see footnotes accompanying the ITU frequency allocation table) the 50 - 54 MHz band is allocated to the Amateur Service on a primary basis. These Countries may refer to the SARL Bandplan. 
Footnotes: a. deleted 
2. USAGE The following notes are referring to the Usage column in the bandplan. As already set out in the introduction to section 3, 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. 
2.1. Footnotes 
b. will be added in the handbook (ACTION Murray Niman) 
c. The intercontinental calling frequencies should not be used for calling within the European part of Region 1 at any time. 
d. Channelized equipment: On this band the FM channel spacing is 20/10 kHz. 
e. For the specification of FM telephony see section Fehler! Verweisquelle konnte nicht gefunden werden.
f. This segment is for simplex use only with no Digital Voice gateways permitted. Embedded data traffic is allowed along with Digital Voice. DV users should check that the channel is not in use by other modes 
g. Refer to Beacons Chapter for coordination of beacons in the beacon sub-band 

For the numbering of FM telephony channels see Fehler! Verweisquelle konnte nicht gefunden werden. In those countries within the European part of IARU Region 1 where it is allowed to set up FM repeaters on 50 MHz, the indicated channels are recommended in order to establish a commonality. In those countries where the National Authorities do not permit repeaters to operate with output frequencies above 51 MHz, repeater output frequencies may be 500 kHz below the repeater input frequencies.(Tel Aviv 1996)

What on earth does this mean: "The intercontinental calling frequencies should not be used for calling within the European part of Region 1 at any time".

I am definitely getting old when I don't even understand the terminology - what is "MGM".

Its possible whoever drafted that does not have English as a first language however its meaning is quite plain and follows normal practice. Don't use the DX calling frequency(s) to QSO within your own continent.
