Re: Ofcoms Auctions off 10GHz Amsat Band and mmWave Opportunities

Murray Niman <mjniman@...>
 

This is more than a Satellite issue - it may concern all 10G...

As drafted a 55dBW power eirp limit is permitted at
10.125-10.225 GHz paired with 10.475-10.575 GHz.

The Ofcom doc permits out of band emissions to be -52dBW/MHz at 14MHz
out of band (ie in ours). Depending on the rolloff, receivers could
still be see a lot of QRM across all Amateur 10GHz slots inc
narrowband/eme, ATV etc

Both of which are in the top half of teh allocation and so our

ask

Given that P3E is intended to enter a highly eliptical orbit,
there
will be periods where it will have a coverage over nearly half of

Ofcom today published proposals for the release of radio

PLEASE NOTE - BR68 Replacement

Murray Niman <mjniman@...>
 

Although it is not yet in force, a draft of BR68s replacement is now
online at:

http://www.ofcom.org.uk/consult/condocs/aradio/lifetimelicence/

You are advised to study the pdf on that page closely
and you will find for example...

a) End of compulsory logging unless requested by Ofcom
b) End of club callsign prefixes such as GX
c) Reintroduction of /A (though possibly not correctly yet)
d) Use of low-power wireless remote control for equipment within the
station, such as for example voice relays with microwave masthead kit
e) Callsign use 'clarified'
f) Remote control of Beacons over amateur Freqs without NoVs
g) Incorporation of all licence classes and old NoVs into one doc
h) New definitions/notes in quite a few places
i) Harrogate Exclusion zone moved to Menwith Hill (important for
Microwave Beacon planning)


The draft is not the subject of a formal consultation but comments
are appreciated ahead of a RSGB-Ofcom meeting next week on July-11
where modest refinements will be considered.

I have been invited to attend that meeting on Microwave matters.
the latter may include Beacon Licensing, 23cms, 55dBW threats to
10GHz, and the 76GHz consultation

It has been thus since the services became lumped with CB as "hobby radio".

Re: Ofcoms Auctions off 10GHz Amsat Band and mmWave Opportunities

Willis, MJ &#92;(Michael&#92;) <m.j.willis@...>
 

Lets be fair about this. We are not currently using the band very much, so how can we expect to justify hanging on to it? We will have to share and it is too late now to complain, we should have made use of this section of the band earlier and we did not. The possibility of there being a satellite in 2008 is not enough. If we had been using it extensively in the last few years, I expect there would have been space made for us. It is our own fault. Use or lose. The same applies to the new users and that is how it should be.
 
We need to ask ourselves exactly what we are contributing through our access to each of our bands and then demonstrate that it is sufficient to justify our continued free access. In the case of 10.45-10.5 we have simply failed to do that.
 
Perhaps we can enter an auction and buy ourselves some spectrum. £1M per 1MHz is not a lot per kHz. What we need to fight and where we might have some success, is in challenging Ofcom's insistence that large blocks of several MHz are sold each time, which is in direct contradiction of technology neutral auctions and favours large businesses over small ones and individual citizens. I would happily buy 100Hz and bid £100. I doubt there will be £100M raised from the 100MHz but for some reason, the minimum amount available is far too large for my needs.

Surely, as the 10,000 to 10,500MHz band is an internationally recognised
amateur band. As such an individual administration may allocate
frequencies within that allocation to other services, but cannot 'insist'
that other administrations restrict usage.

Therefore should a point-point link exist of which one end points directly
at an amateur station in another administration, the user would have to
'suffer' the possibility of interference from that station.

Did not this happen in a small way back in the 70's when the French
administration decided to allocate part of 23cms soley to their military?

Is this not another case of the administration not being aware of amateur,
UK, internation and (let's coin a new description) extra-terrestion usage?

PI9A NOT qrv during July contest

Eene de Weerd <pa3ceg@...>
 

Hello all,

 

Due the lack off a good /P qth for the 2/70 group and several other (personal) circumstances, the PI9A group will not act in the July contest.  It was a hard decision after years off continuing contesting but hopefully it give us time for preparing the new bigger autobus as mobile shack. Hope to see you all in the log in the coming September contest from the North Sea coast (JO33DJ).

Wish you all a lot off success and good propagation during this weekend.
