I'm sure these wont last long, but for my 15 minutes of fame, here are a couple of additions for 'firsts' on 23cm (1.3GHz) from England

Country Prefixes Date Time Station A Station B Mode Propagation Confirmed Source
England G,M,2E 07/03/07 16:00 G0DJA GM4CXM CW Tropo Wales GW, MW, 2W 20/03/07 22:15 G0DJA GW8ASD SSB Tropo


I'll dig back in my old 10/24GHz logs and see if I have any others that would, temporarily, fill some gaps.

Ok chaps...

The full datasets for all GB entitities, rules and application form
are now online, linked via 'Firsts' on the www.microwavers.org
Operating page.

All new entries to XDY....

May I commend the entire scheme to you all - ENJOY!

Murray G6JYB


PS - will tidy up other web page issues shortly

Thanks Murray,

If the intention was to drop my jaw, you succeeded.
Then I noticed 3.4 GHz at the top of the page!!!
Looking forward to seeing the rest of the bands when time allows.

As John has mentioned, floods of corrections may certainly flow as
not everyone will have made a claim for a "first country contact"
or
publicised such contacts in publications where the information is
often gleamed.
On 2m I am credited with GM to TF and YU firsts despite never
having
submitted such claims but nobody has ever tried to update the
information with earlier contacts. The flip side is that many years
ago I did claim first 2m GM to HB0 and C31 and it was never
recorded!

Almost time for some folk to dust off old log books me thinks!

Hi all,
Can anyone point me to a reference point of first contacts
between
different countries on Microwave bands from the UK?

The page on the UKuG site only has information for 23cm from
Wales.
Can't find anything on the RSGB website.

Hi all,
I will be active Sunday on 23cm.
Probably +/- 1296.190
If aircraft dependent then better to try with me earlier rather than later plus I may not be on at the end as it is a long enough duration.
Talkback on ON4KST or 144.175
I can also be contacted on Skype (gm4cxm) or 0141 942 6657 for skeds.

Just got my home PC back up and running, after another HDD crash... Now using a different HDD!

So, I plan to be on 23cm tomorrow as well. Not all of the time, but hopefully at the start and at various times during the day, domestic commitments allowing. I will have ON4KST running, I may prop the 2m/70cm vertical up somewhere and, if anyone wants to arrange a sked, I'll check here and my email inbox during today and tomorrow.

Hope to hear a few people tomorrow.

Good Luck - Dave (G0DJA)

On a range set up at the South Birmingham RS we found a Procom 24 GHz 48cm dish a dB or so below its specification.

Thanks for that - very interesting. I looked up the gain of the 48cm
Procom 24GHz dish. It should be 36 dBd. We measured 38 dBi, so if
Procom's figures are accurate, so was our range.

The 70cm centre fed dish for 10GHz is a 0.4 F/D spun aluminium dish.
Theoretically, if 100% efficient the gain is 37.6 dB. We measured 35.6
dB. So 2 dB loss. An efficiency of 63%. I do not think it is likely it
is that good as we did not optimise the feed. I expected something more
in the 50-55% range.

The feed itself is simple to make in aluminium on a lathe, it is a
circular waveguide of 20mm inside dia with a choke ring of 50mm dia and
20mm depth. I made it in two parts because I am not good at lathe work.
It would be easy to make it in one piece out of some 2" bar stock with
the right lathe tools. I feed it with coax, using a probe 1/4 guide
wavelength from the shorted end. I tuned the match with a screw opposite
the probe.

Re: RAL 2007

Steve - WB0DBS
 

I second the comments made by Dave and all the others! This is my third year attending RAL, and I've thoroughly enjoyed each one. They are one of the highlights of my trips to the UK. I've occasionally heard comments like "well, it's not Martlesham, it's not Microwave Update, etc." and I agree - but it's every bit as good as any of them! I enjoy the smaller gatherings as there's more time to visit with old friends and make new ones. Though the 'bring and buy' may have been a bit smaller this year, I saw plenty of goodies going to new homes. To the presenters, a big "well done!" It was apparent that a lot of time and effort went into each presentation. I look forward to next year, and am hoping the XYL will be able to make the trip with me.

73,

Steve, WB0DBS

Thanks to Brian G4NNS for a providing the antenna testing session and the 10GHz moon bounce demonstrations at his QTH on Saturday. Also thanks to Brian for arranging a first class meal at the Red Lion with great company, even the XYL enjoyed it! Thanks to Mike G0MJW for arranging the venue and the test equipment, like Neil G4BRK I am not able to get my hands on such sophisticated test gear and now I really know how good my preamp is. Thanks to all the presenters for some most enjoyable and informative presentations.

If you click on the tabs at the foot of the tables you can select whatever band you wish, so have a look at 1.3GHz and please let me know of any additions and changes you are aware of.

Sorry!
It also pays to brows down to the bottom of a page and see other bands
