The International Amateur Radio Union and its more than 160 Member
Societies representing countries around the world, will celebrate
World Amateur Radio Day on 18 April. The theme for this year's
celebration is Amateur Radio: The First Technology-Based Social
Network. Amateur Radio operators have been the leaders in developing
many of today's modern electronic and communications marvels.
The Six and Ten Reporting Club is an informal group of radio
amateurs, mostly from the UK, who are interested in propagation
studies at frequencies around the HF-VHF boundary, mainly the 6 and
10 metre amateur bands. The club produces a monthly newsletter, the
Six and Ten Report, that includes analysis of 28MHz propagation based
on beacon monitoring, analysis of 50MHz activity reports broken down
by propagation mode, reports and discussions on unusual propagation
events, compilations of solar and geomagnetic data, lists of activity
world-wide, beacon news and results of on-going experiments. The
Report is usually published on this site about 5-6 weeks after the
end of the month by g7kse at http://g7kse.co.uk/6and10.
The BBC has issued a report investigating the potential interference
to broadcast reception from Power Line Telecommunication (PLT)
equipment used in the home. Read the BBC Research White Paper by

stations also send their Province code.
And now the solar factual data for the period from the 4th to the
10th April, compiled by Neil Clarke, G0CAS on the 11th of April.
Solar activity varied between very low to low. Small strength C class
solar flares took place on the 6th, 7th and the 9th. These had little
effect on propagation but on occasions faint coronal mass ejections
were observed. Solar flux levels declined from 117 units on the 6th
to 105 by the 9th and the 10th. The average was 110 units. The 90 day
solar flux average on the 10th was 101 units, that's two units up on
last week. The last time the 90 day solar flux average stood at 100
units was in February 2005 during the declining phase of the last
sunspot cycle. X-ray flux levels varied little day to day and
averaged B2.9 units. Geomagnetic activity was quiet till mid morning
of the 6th when a coronal mass ejection arrived. The following
disturbance was strong but short lived and at its peak caused a
widespread radio aurora that extended down to southern England. The
Ap index on the 6th was 26 units and the average was Ap 10 units.
Solar wind data from the ACE spacecraft saw solar wind speeds decline
from 600 kilometres per second on the 4th to 420 by the next day.
Speeds increased on the 6th associated with the disturbance. Particle
densities were low every day. Densities on some days were below one
particle per cubic centimetre. Bz on the quiet days varied between
minus 3 and plus 4 nanoTeslas and between minus 10 and plus 7
nanoTeslas during the 6th.
And now the solar forecast. This week the active side of the Sun is
expected to be looking our way. Solar activity is expected to be low
bout could increase higher than that on some days. Solar flux levels
should increase and later in the week could be approaching the 120's.
Geomagnetic activity should be quiet every day, however, a small
disturbance could take place around midweek. MUFs during daylight
hours at equal latitudes should be around 24MHz for the south and
21MHz for the north. Darkness hour lows should be about 10MHz. Paths
this week to Japan should have a maximum usable frequency with a 50
per cent success rate of around 21MHz. The optimum working frequency
with a 90 per cent success rate will be about 15MHz. The best time to
try this path will be between 0900 and 1200 hours. The second half of
April normally sees the start of the summer sporadic-E season for the
northern hemisphere. In fact during the 10th a good opening took
place on 50MHz to Iberia.
And that's all for this week from the propagation team.
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 Tuesday before transmission.
