Jakkoli G4SWX je VKV manažerem RSGB
(a tedy i OK1TEH), s jeho níže uvedenýn vyjádřením většinově nesouhlasíme.
Způsoby, jak efektivně bránit (a ubránit) radioamatérská pásma jsou jiné,
než John, který mikrovlnnou zkušenost nemá, popisuje. Především je
třeba bránit DX segmenty, kde se používají řádově větší výkony, než
u komerčních zařízení v kmitočtovém sousedství. Ta možnost existuje, když
se podaří získat ke spolupráci odborníky na datové komunikace a správu
kmitočtového spektra. Znamená to ale vyjít z malé ohrádky prolobbovaného
prostředí České republiky a vydat se jednat do zahraničí. Ovšem ne všichni
zástupci evropských radioamatérských asociací tuto nezbytnost chápou.
Zatuchlý český píseček nadnárodním zájmům radioamatérů nesvědčí. Navíc
duševní obzor některých radioamatérů končí na 28MHz, u jiných na

Although my personal interests in the hobby are EME and narrowband VHF DX
we must increasingly 'sell' and encourage regular wider bandwidth amateur
activity. I am really impressed by ham-net in Germany but such activity
seems to have not take-off in the UK. Sadly my 13cm data link produces
more MHz/hour than all of the rest of the narrowband amateur activity in

fair to say that good relations between amateur organisations and
regulators to a large degree depend on individuals. As radio amateur age
profile over time reduces number of amateurs within the regulator
organisations, history and knowledge of amateur radio is declining and
it’s a challenging task to keep this knowledge up to a healthy level by
That is all true. However I dedicate most of my time to dealing with the
key, non-radio amateurs within the UK telecommunications regulator; Ofcom.
Radio amateurs within the regulatory bodies have somewhat narrow views
based upon their own experiences. As somebody experienced with other
aspects of dealing with the telecommunications regulator, wireline
security, I guess I also take a somewhat more pushy attitude with the
regulator than most amateurs.
> This situation plays against us, and it becomes very difficult to
fight the argument of “to the benefit of society” when a new, or secured,
allocation for mobile data is on the table.
I disagree! The debate which won us, in the UK, an allocation of
146-147MHz, although temporary, was made on the basis of 'not more of the
same' and 'filling-up' the spectrum. My bid was on the basis of
experimentation with wider bandwidth technologies than are not usually
used at VHF and could not be easily accommodated alongside our current
144MHz usage. This caused a lot of disquiet in amateur circles as I made
it very clear that FM and traditional narrow-band modes were not welcome
in 146-147MHz! i.e. entirely the opposite of the recent IRTS low-VHF band
After I presented the results of reduced bandwidth(500KHz) digital amateur
television on 146MHz to the UK regulator; Ofcom I was asked to do a
similar presentation to Ofcom's business radio user group.
The result of this second presentation was the offer of 70.5-71.5MHz,
again on a temporary basis!
In private I can tell you of a significant number of wider bandwidth
experiments that I suggested might happen that have failed to
My most recent presentation and video involved HD-RB-DATV and again I was
asked to present to the regulator's business radio user group (where there
are a lot of amateurs). Again the feedback was fantastic, particularly
from the head of spectrum policy. When I asked him why, the reply was
enlightening. It seems that at UHF many outside broadcast systems employ
2-way links consuming 10MHz each way. It seems that full broadcast
standard is not required for the feedback but HD is. Amateurs had just
proved that HD was possible in 500KHz although at a slower bit rate.
Whilst I have had a lot of luck and the support of many UK amateurs (I am
but a 'front-man') I believe that such a non-traditional approach to the
regulator can pay off.
> Again, I fully agree with “use or loose” but we will not turn around
the use on those bands to match a discussion with mobile data (e.g. How
many more need to be active to back up that argument? What is a realistic
Amateur radio will not win the spectrum argument in the 21st century that
way. Traditional narrow-band usage will not generate significant influence
the regulators of today as there are not enough of us to do much about it.
However when I ran a demonstration of remote station EME from the
regulator's HQ I was deeply quizzed on amateur digital protocols with a
lot of FEC and how they might be applicable to telemetry. Aspects of
national training perhaps, development of novel ideas and experiments yes
and a lot more that as an old man (65) I have not thought of!
> Depending on individuals, there may be attempts to find national
solutions for amateur radio allocations, but on the CEPT level I think it
will be very difficult.
In CEPT we need technically talented people to pull apart some of the
badly founded technical policy ideas that I often see. i.e. the bits/Hz of
LTE that somehow does not include the guard channels plus many other
examples that seem to reinforce the 'fog' that we face..
> A discussion on how we can expand information on our activity outside
our own magazines could give some ideas on publicity and one piece to the
Being a VHF manager is about selling the amateur radio story at VHF/UHF to
the spectrum regulator. I grab anything that I think might interest this
audience and push it hard. Some things do not develop to fruition but with
luck there will be some aspects of the hobby that can be made appealing to
non-radio amateurs within the regulatory bodies. Every country is
different but I have had discussions in at least 2 other Eu countries
where I know that the radio regulator is looking for something different
from amateur radio.
