The RSGB annual Construction Competition is still open for entries.
The aim of the competition is to encourage home construction,
experimentation, design and innovation. The competition can be
entered by individual members or groups of members where the build
team will be treated as a single entrant. The closing date has been
extended to 6 October and any project that you have built, other than
one that was a previous winner in this competition, may be entered.
Judging will take place at the RSGB Convention on the 14th of
October. Full details are at tinyurl.com/GB2RS-0924c

The RSGB EMC Committee has been investigating VDSL broadband
interference on the HF amateur bands for three years now. To increase
the amount of evidence available, the Committee set up a survey at
tinyurl.com/GB2RS-0309A to collect current signal levels at the
frequencies of VDSL band transitions. There are still lots of
responses being received so the deadline has been extended; it will
remain open this week. Please fill it in, or persuade your fellow
amateurs to do so. If you have part-filled in the survey, you should
be able to re-open and complete it, or you can make a new entry and
the earlier version will be deleted. Thanks to everyone who has
participated. Some people found they had VDSL RFI that they were
previously unaware of. The survey results will be presented at the
RSGB Convention and published on the RSGB website.
A valve workshop will be held on the 14th of October at The National
Museum of Computing, Bletchley Park MK3 6EB. If you have a basic
knowledge of electronics and can read an electronic circuit diagram
then they will show you how electronics began, following its critical
components for its first 50 years. Find out about valve history, how
to handle and test valves and how valves are used in amplifiers,
radios and computers. Full details can be found at
tinyurl.com/GB2RS-0309B

The RSGB has recently responded to two Ofcom consultations affecting
amateur microwave bands, as part of its ongoing strategy to protect
amateur spectrum. The latest input in a series regarding 5GHz has
been made in relation to Ofcom's consultation to liberalise Fixed
Wireless Access channels. This would affect amateur narrowband and
particularly satellite reception. Additionally, at even higher
frequencies there has been a response to an Ofcom Call for Input
regarding future fifth generation smartphone handset and base
stations. In a marked change from current systems these are expected
to use new frequencies in or near our 24 and 47GHz Primary amateur
bands. Both consultation inputs were developed in the RSGB Spectrum
Forum with assistance from special interest groups including UK
Microwave Group and AMSAT-UK. Details can be found at
tinyurl.com/GB2RS-1001b

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO
on Friday the 29th of September.
Last week was a mixed bag in terms of HF propagation. With the solar
flux index just into the 90s, amateurs were able to take advantage of
the improving autumnal conditions. At times, maximum usable
frequencies over a 3,000km path were stretching up to and beyond
21MHz, with openings to the US being reported on 15 metres. But a
geomagnetic disturbance due to a coronal hole on the sun saw the K
index soar to six on Wednesday, with associated auroral warnings.
At noon on Wednesday the critical frequency over the UK managed to
hit 8.125MHz, as measured at RAF Fairford. But an incoming solar wind
stream above 600km/s, with a south-facing Bz magnetic component, took
its toll. By late evening Wednesday predicted MUFs over 3,000km were
below 14MHz. If the solar wind has a south-facing Bz magnetic
component it is more likely to couple with the earth's magnetic field
and cause disruption. An even more unsettled ionosphere saw this
continue on Thursday as the K index hit a very stormy seven.
Next week, NOAA predicts the solar flux index will be in the mid 90s
and geomagnetic conditions may be more settled. This could mean more
fun on the HF bands.
As we move into October we can expect HF conditions to improve on
east-west paths. Make sure you are using the latest smoothed sunspot
number of 22 with VOACAP-based prediction programs for the best
results.
And now the VHF and up propagation news.
The weekend and beginning of the coming week looks likely to be
affected by low pressure, with potentially windy conditions in the
north. The unsettled weather will also mean that GHz bands rain
scatter could be possible.
High pressure is set to move in towards midweek and should place
Tropo at the top of the operating list through to the end of the
week. Models differ slightly in the exact placement of the high, but
most allow the centre to drift east across southern Britain, while
leaving a linking ridge back to another large high north of the
Azores. What this means for the VHF bands from the UK is some fairly
good Tropo, especially into the near continent and across Biscay
towards Spain and perhaps farther south. Unfortunately, northern
Britain remains closer to low pressure and probably misses out on the
main Tropo action, although recent activity from CMEs highlights the
possibility of aurora if the sun continues to be disturbed.
There are no significant meteor showers, this week, so continue to
look before dawn for the best random meteor scatter contacts on the
lower VHF bands.
Moon declination goes positive again on Thursday, so expect
lengthening Moon windows and falling losses this coming week as the
Moon heads for perigee a week tomorrow.
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 gb2rs<at>rsgb.org.uk to arrive by
10:00 on the Thursday before transmission.
