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

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 Murray http://www.ofcom.org.uk/consult/condocs/10ghz/spec_condoc.pdf --- In ukmicrowaves@yahoogroups.com, "Murray Niman" <mjniman@...> wrote: proposed by Ofcomto these ambitious projects(P3E thereand P5A) both have a downlink in the 10GHz satellite band aboveforeign muchwill be periods where it will have a coverage over nearly half oftheearth.

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 regards Murray

Hi folks,
Please let me know what your plans are for this coming Sunday's millimetre band contest and I'll put a copmnposite list around later in the week. If activity warrants it I might drive across to the Welsh borderlands or SE to S. Lincs. Failing that it will be the usual sites in the Peak District... Alport, Merryton Low, etc. I'll have the usual 24 and 47GHz gear. Peter, G3PHO

Caution: Re GRPS modem

I believe that O2 lock their cards to their network (G3UKV experience), and
only allow contract customers to use them, so pay-as-you-go doesn't work. Worth checking first. Chris g3wie

Re: Ofcoms Auctions off 10GHz Amsat Band and mmWave Opportunities
Willis, MJ \(Michael\) <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.
Mike

Its more than just worrying
I am told that Phase 3E and 5A are planning to use Phase 3E: linear X band downlink is 10490.168 - 10490.118 MHz Phase 5A (Mars): 10490.143 Both of which are in the top half of teh allocation and so our receivers would face the full force of upto 55dBW eirp being proposed by Ofcom Please pass this on to non-UK users who have been looking forward to these ambitious projects Murray --- In ukmicrowaves@yahoogroups.com, "g8ubn" <grant@...> wrote: foreign country?

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.
Best 73’ Eene

Re: Ofcoms Auctions off 10GHz Amsat Band and mmWave Opportunities
g8ubn <grant@...>
This is particularly worrying as the next two Amsat-DL projects (P3E
toggle quoted messageShow quoted text
and P5A) both have a downlink in the 10GHz satellite band above 10475MHz. What would be the situation if the winner of the 10GHz license suffered interference from a satellite desinged and built in a foreign country? I haven't done the system calculations, it's just a hypothetical question - would a UK licencee have any authority to ask Amsat-DL to restrict operations of the 10GHz downlink? 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 the earth. It probably won't cause interference to the new 10GHz licencee, but what if it did? regards Grant

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