recommendations.
This weekend, the Worked All Germany contest ends its 24-hour run at
1500UTC today, the 17th. Using SSB and CW on the contest bands
between 3.5 and 28MHz, the exchange is signal report and serial
number. German stations will also send DOK.
Today, the 17th, there are four contests taking place. The first is
the 50MHz AFS contest, between 0900 and 1300UTC, using all modes and
the exchange is signal report, serial number and locator. Stations in
the UK and Commonwealth Dependencies also exchange the first two
letters of their postcode.
The second contest is The UK Microwave Group 24 to 76GHz Contest runs
from 0900 to 1700UTC. Using all modes, the exchange is signal report,
serial number and locator.
The IRTS 40m Daytime Counties Contest runs from 1200 to 1300UTC and
is the third contest on the 17th. It uses CW and SSB and the exchange
is signal report and serial number. EI and GI stations will also send
their County code.
Finally, for the today, the second Rolling Locator, or RoLo, contest
runs from 1900 to 2030UTC. It is CW-only on the 3.5MHz band. The
exchange is signal report and the rolling locator.
On Monday, the eighth FT4 Series contest runs from 1900 to 2030UTC on
the 80m band. The exchange is report and 4-character locator.
The 1.3GHz UK Activity Contest takes place between 1900 and 2130UTC

number and locator.
On Thursday, the 70MHz UK Activity Contest runs between 1900 and

Next weekend, the UK EI Contest Club DX SSB contest runs between
1200UTC on Saturday to 1200UTC on Sunday. Using the contest bands
between 3.5 and 28MHz, the exchange is signal report, which is
optional, serial number and your district code.
Now the radio propagation report, compiled by G0KYA, G3YLA & G4BAO on
Friday the 15th of October.
Last week saw a mixed bag in terms of HF propagation with good
conditions at times, but horrendous conditions mid week after a
coronal mass ejection saw the Kp index shoot up to six. Matter from
the CME, which was accompanied by an M1.6 solar flare on the 9th of
October, hit the Earth in the early hours of the 12th. A geomagnetic
storm then ensued and widespread visible aurora were reported at high
latitudes.
On Tuesday MUFs were affected adversely with maxima over a 3,000km
path down from 28MHz to less than 14MHz at times during the day.
By Thursday, and with the Kp index back down to between zero and two,
signals had recovered to near normal levels, with a maximum daytime
critical frequency of 7.125MHz being recorded on the Chilton
Digisonde, which equates to more than 27MHz over a 3,000km path.
This does go to show that we can expect more CMEs, and poorer
conditions at times, as we head towards solar maximum in a few years'
time.
Next week NOAA predicts the solar flux index will be in the range
85-90 with a maximum Kp index of four on the 19th.
So make the most of the Autumnal HF conditions and work as high in
frequency as you can to minimise D-layer absorption.
And now the VHF and up propagation news.
The coming week's weather will change to mixed and unsettled, with
little chance of Tropo propagation, caused by periods of rain,
showers and strong winds. At best we can hope for some rain scatter
activity.
The exact time when these changes of type occur in our weather
patterns is one of the hardest for the models to get right, but at
the moment most suggest Sunday night into Monday.
Since the autumn is typically a good season for auroras, perhaps some
warbling auroral notes will return again after last week when plenty
of auroral QSOs were reported on 144MHz. Sadly for the UK, they were
almost exclusively for the more northerly Nordic countries. A few
northern UK stations, namely G4KUX, MI0XXZ and GM4VVX reported a few
auroral CW QSOs on the 12th.
The 21st sees the peak of the Orionids meteor shower with a ZHR of
15. Orionids are pieces of Comet 1P/Halley, famously known as
Halley's comet. Add this to two small meteor showers, the Epsilon
Geminids with a ZHR of three peaking on the 18th, and the Leonis
Minoris with a ZHR of two peaking on the 24th, next week should be
good for meteor scatter enthusiasts.
Moon declination goes positive again on Monday so we'll see the Moon
reaching higher elevations at its zenith. Path losses are still
increasing as we are past perigee.
A seasonal reminder from the team to do your end of summer check on
those antenna ropes and fixings before we see too many windy days.
And that's all from the propagation team this week.
And that's the end of the main news for this week prepared by the
Radio Society of Great Britain. Items for inclusion in subsequent
bulletins can be emailed to radcom<at>rsgb.org.uk to arrive by
10:00 on the Thursday before transmission.
Our thanks to Andy G4TNU for providing this RSGB feed.
