To: info-hams@ucsd.edu
Good morning. It's Sunday the 11th of September and here is the GB2RS
news broadcast, prepared by the RSGB and intended for all radio amateurs
and short-wave listeners.
And we start this week with our congratulations to Katie Cannon, who has
passed her 5 words per minute Novice Morse test at the age of only
seven. She took the test at Reading on the 16th of August and is one of
the youngest people to have passed this test.
The seventh Amateur Radio Direction Finding World Championships take
place this week in Sweden. For the first time the RSGB has sent an
official four-member team to represent the United Kingdom.
Later this month, the 160 metre UK National ARDF Final will be held in
Northamptonshire. For information on all types of direction finding,
contact Brian Bristow, G4KBB, whose address is correct in the RSGB Call
Book.
Now some sad news: Midlands GB2RS news reader Tom Douglas, G3BA, passed
away last week. He was well known as someone who put a great deal into
amateur radio over many years. He will be greatly missed. A full
obituary will appear in the November edition of Radio Communication.
The next RSGB Microwave Round Table meeting takes place on Sunday the
13th of November at the British Telecom Laboratories, Ipswich, Suffolk.
The event is organised by the Martlesham Radio Society and will
commences at 10am. Attractions will include the usual round table
sessions, test equipment and bring and buy facilities. The provisional
lecture programme includes talks on 10GHz rainscatter, 24GHz and 47GHz
activity, as well as an update on the 10GHz Phase 3D transponder by
Freddie, ON6UG. For security reasons, all access is by advanced booking
only, and it is important to give the names of all persons attending in
a group if you request multiple tickets. Tickets can be obtained by
sending a Self Addressed Stamped Envelope to Roy Smith, G0RRC,
'Lykkebo', The Street, Burstall, Ipswich, IP8 3DN.
It has been reported elsewhere that a number of rallies due to be held
on Sunday the 25th of September have been cancelled. In fact, only the
Peterborough event is cancelled. Four events are still taking place: the
Harlow Amateur Radio and Computer Show, the Three Counties Rally, the
North Wakefield Radio Club Rally and the Scottish DX Cluster Support
Group Junk Sale. Full and accurate information of all of these events
can be found in the September edition of Radio Communication. We will of
course be giving you details via GB2RS next week.
An RSGB Regional Meeting takes place on Saturday the 22nd of October at
the New Friend's Hall, Purdown, Stapleton, Bristol. The doors open at
12.30pm, when light refreshments will be available and the meeting
commences at 2pm. Several members of the RSGB Council will be in
attendance plus representatives of HQ. Full details will appear in the
October edition of RadCom which is scheduled to be posted to all RSGB
members within the next ten days.
Now some items of HF DX news from the weekly RSGB DX News Sheet which is
edited by Brendan McCartney, G4DYO.

Self followup. I found the database. I poked through
upenn's localhosts file and found that while mipg.upenn.edu
doesn't exist anymore, mipgsun.mipg.upenn.edu does.
It's under pub/yee as rptr010.Z as purported on the Mosaic

your chance to update your screens.

is it me or did the repeater database creators drop off

to the database seem fine, but I can't FTP the entire

Williams, whose name appears all over the pages as the

Perhaps someone here can tell me where to FTP the entire

SETIQuest is a new quarterly print/electronic mail (E-mail)
periodical containing news, technical information, and tutorials
devoted to bioastronomy and its subset, SETI (Search for
Extraterrestrial Intelligence).
SETIQuest is published for professionals, serious amateur
astronomers, and individuals curious about this fascinating field of
observation. SETIQuest fills the need for a specialized astronomical
publication devoted exclusively to the on-going search for evidence
of life in the Universe. Such evidence could be intentional or
inadvertent signals of other civilizations. Such evidence could be
found in spectral signatures of biological activity on extrasolar
planets or in the interstellar medium.
SETIQuest is written and edited for the scientifically literate
individual taking part in the progress of our technological
civilization, with articles by amateur and professional scientists.
SETIQuest includes information about hands-on observational programs
that can be carried out by individuals and groups of amateur
astronomers at radio and optical wavelengths.
SETIQuest is filled with articles covering topics such as:
* Tutorials about bioastronomy and SETI
* Microwave or optical SETI as practiced by amateurs
* "Do-it-yourself" participation in bioastronomy and SETI activities
* Book reviews
* Regular commentary on issues relevant to SETI and bioastronomy:
SETI and the political milieu
Philosophical issues regarding the prospects of success and
failure in the search
SETI as a parable of science versus pseudo science
Publications Watch: Summaries of recent scientific/general
publications relevant to SETI

Next some VHF contest news:
Another RSGB 24GHz Summer Cumulative Contest takes place from 0900 to
2100 UTC today, Sunday the 11th. See April's RadCom for details.
Also today, the Worked All Britain 144MHz High Power Phone Contest take
place from 0900 to 1700 UTC and there are sections for fixed, portable,
mobile and Short Wave Listener stations.
The RSGB 70MHz Trophy and SWL Contest takes place from 0900 to 1400 UTC
on Sunday the 25th of September. There are three sections: Single
Operator fixed, All others and Listeners. See July Radcom page 82 for
further details.
Special event stations active during this week include:
GB2OWM which is active until Thursday the 15th from the Orkney Wireless
Museum on the island of Ronaldsay, WAB area ND49, during the Fourth
Orkney Science Festival.
Today, GB0RAF is operated by members of the RAF Amateur Radio Society
from the Lincoln Hamfest, which will be on 80 and 40 metres, CW and
SSB. Also GX8MWA and GX5MW which will be operated by the Medway Amateur
Receiving and Transmitting Society at the Strood Steam Rally, and GB2NFR
will be on air from the North Foreland area of East Kent, commemorating
the wartime radar sites operated from there.
And now the solar factual data:
The period from the 29th of August to the 4th of September saw a
considerable rise in sunspot indices, solar flux levels and the X-Ray
flux. Two M class flares were reported, but the geomagnetic field has
remained generally quiet.
On the 30th of August sunspot group number 7773 rotated into view and
two M class flares erupted, the first an M1.1/SF and the second an
M1.4/SF. Smaller sub-flares and radio noise bursts were also reported.
The daily sunspot indices started the period at 23 and rose every day
reaching 101 by the 3rd giving a mean of 47. Solar flux levels have also
climbed from 78 units on the 29th of August up to 94 units by the 4th of
September, with the period averaging 86 units. The 90 day flux average
was 78 units on the 4th of September.
Geomagnetic activity has been quiet throughout the period with the Ap
indices averaging 5.5 units. The state has been 'Nil nothing to report'.
The aa indices for the 23rd to the 29th of August, as supplied by the
British Geological Survey, was quiet with the daily indices averaging
12.9 nanoTeslas, about K2. There were many periods down to only 5
nanoTeslas.
The X-Ray flux levels increased very considerably, reaching B4.3 on the
30th. The period averaged B1.9 units. The electron fluence levels have
been at moderate throughout the period. This, and the seasonal changes,
have resulted in a modest improvement of ionospheric conditions. The
monthly RI sunspot number for August was 22.8 with a maximum of 44 on
the 14th and a minimum of 10 on the 2nd and 22nd. The smoothed sunspot
number for February 1994 was RI 35.0 +/-5. Bartells rotation 2199
started on the 30th of August.
I'll repeat the figures. Spots - 47; Flux - 86; Ap index-5.5; X-ray flux
B1.9. August Spots RI 22.8.
Now the ionospheric data for Central France:
The F2 daytime critical frequencies at Poitiers, as reported by Meudon,
averaged 6.7MHz, though the 30th and 31st of August were up to 7.2MHz.
The darkness hour lows averaged 3.0MHz, though levels varied from 2.8 up
to 3.6MHz. No spread F was reported, showing that the ionosphere is
stabilizing considerably. The highs are now around 20.00 hours and the
darkness lows around 04.00 hours.
I'll repeat the figures. Highs - 6.7MHz; lows - 3.0MHz.
Now the ionospheric data for the north:
The F2 daytime critical frequency data from Ekaterinberg is now
available again and from the data we have, the daytime levels are about
5.7MHz and the darkness hour levels 3.5MHz. We hope to catch up next
week.
I'll repeat the figures: Highs - 5.7MHz; lows - 3.5MHz.
And lastly the solar forecast:
This week, the quieter side of the sun will be looking our way and solar
flux levels are expected to be about 75 units, with geomagnetic activity
quiet. Ionospheric MUFs in the south during daylight are expected to
reach 21MHz, and the darkness hours about 10MHz. Northern stations
should find the ionosphere more stable now. North/south paths are
expected to be the best.
And that's the end of the solar information.
Finally in the main news, SSL has informed the Society that as of last
Wednesday morning, the latest callsigns allocated were in the G0 Victor
Foxtrot and G7 Tango Quebec series, and Novice calls in the 2 0 Alpha
India and 2 1 Delta Juliet series.
