Propagation of Radio Waves.
The effect of the Ionosphere on the Sky Wave.
The propagation of radio waves through the ionosphere is similar in
many respects to the water-air analogy that was the subject of last
weeks column.
Each ionised layer, because of the variation in electron density through
the layer, presents a constantly changing medium for the passage of a
radio wave which enters the layer. The velocity of the wave in the ionised
layer increases as the electron density increases, and therefore increases
with the depth of penetration of the wave into the layer.
The conditions required to return a sky wave to earth can be expressed in
terms of the refractive index of the ionised layer. Although somewhat
affected by the earths magnetic field and collisions between vibrating
electrons and gas molecules, the refractive index is determined primarily
by the electron density and the frequency of the radio wave.
Unfortunately, the equation determining the refractive index cannot be
expressed in RTTY mode. However, the principle has been stated in the
previous paragraph, and is basically the same as the water-air equation.
As pointed out last week, the smaller the refractive index, the greater
is the degree of bending, and hence, as the wave train enters the ionised
layer, the upper portions of the wave fronts are bent or refracted to a
greater extent than the lower portions. since the upper portions are in an
area of lower refractive index (with a greater velocity).
This part of the article will continue next week

Solar flare activity was very low all week.
Geomagnetic activity observed for the Australian Region was quiet to
unsettled on 12/14th and 18th and quiet on 15/17th.
Southern Australian Ionospheric F2 critical frequencies were near
predicted all week except for the 17th when frequencies were near
predicted to 15 per cent enhanced.
Forecast for 19/25th May
Solar activity is expected to range from very low to low. There are
currently no active regions on disk, but it is possible returning
region 875, which is due to appear in the next few days, may bring
with it an increase in solar activity as it was the source of M-class events on its last transit.
Geomagnetic sees quiet to unsettled conditions expected, with isolated
active periods early in this forecast week - as solar wind parameters
remain elevated due to a geoeffective coronal hole.
Frequencies should be near predicted monthly values, with some depressed
periods and disturbed ionospheric conditions possible for mid-high
latitudes early in the week. No Short Wave Fadeouts are expected.

3rd EUROPEAN PSK DX CONTEST
The Scottish-Russian ARS has the honor of inviting the radio amateurs all over
the world to participate in the 3rd annual European PSK DX Contest (1200z
20.05.2006 - 1200z 21.05.2006). The objective of the contest is to establish
as many contacts as possible between radio amateurs around the world and radio
amateurs in Europe by using the BPSK31 mode. Everybody can work everybody for
QSO and multiplier credit. More information is available at
http://www.eu.srars.org

extended his stay until Jul (He was supposed to go QRT in June). During his
last month there he will focus on 6m. Listen to 50.110 MHz CW/SSB. If he is
not on 6m watch for activity on 160-2m on CW SSB and Digital modes. QSL via
his home callsign LA4GHA, by the bureau or direct to Roger Bjoergvik, The
Registry, Court of BiH, Kraljice Jelene 88, 71 000 Sarajevo, BiH.
LIGHTHOUSE ACTIVITY
Chris G1VDP informs OPDX that he will be operating from the Pendean Lighthouse
(ENG-101, Locator IO70ed) in Cornwall England May 31. During his portable
operation Chris will be using a FT897 into an ATAS 120 antenna with 100W outpu
on 40/20m and 10m if the band opens. He may also try some PSK31 on 40m if the
conditions will allow, and his Laptop stands up to it. Suggested frequencies
are 40m (7064 kHz +/- QRM), 20m (14265 kHz +/- QRM)
and 10m (28475 kHz +/- QRM).
A special QSL card will be available following the operation and will be sent
via the bureau (direct QSLs are to include SAE and return postage costs using
the (QRZ.com) address).
PI25, THE NETHERLANDS (Special Event)
During the month of May the VERON Department A54, 'Etten-Leur' will be
celebrating its 25th jubilee year. The club station PI4ETL will be using
the special callsign PI25ETL between Jun 24 and Jul 9. Club members will be
active with this special callsign on various HF and VHF bands during this
period and PI25ETL will participate in the IARU HF Championships Jul 8-9
as a Multi-Single entry. A special 'Worked A54 Award' will become available
for working PI4ETL or PI25ETL during the months of May Jun and Jul. Details
can be obtained from PA0ATG at: pa0atg at amsat.org
RUSSIA NEWS
It has been reported that some changes have taken place for Russian amateurs
(as of 'a couple of weeks ago). Russian amateurs can now run a KW and also
operate up to 7.200 MHz with the government there providing these new
operating factors. This news is only true for the former Soviet state we now
call Russia and not necessarily the other former Soviet states.
VI9, NORFOLK ISLAND (Pitcairner landing celebrations by Jim Smith VK9NS)
'Although I have lived on Norfolk for almost 26 years and Kirsti many more
years neither of us are Norfolk Islanders. Jun of this year marks the 150th
Anniversary of the landing of the people of Pitcairn Island, the descendants
of the Bounty Mutineers on Norfolk Island. The discovery of Pitcairn Island
with its 'lost' population is a whole saga in itself. The subsequent movement
of this population was sanctioned by Queen Victoria. The British government
then arranged their transport to and settlement on the vacant possession of
Norfolk Island. (Some Pitcairners subsequently wished to return 'home' to
Pitcairn. This was allowed and carried out on a one off and final basis.
Hence the current Christian and Young, etc, families resident on Pitcairn
Island.) The celebration of this unique migration is special to the Norfolk
Islanders (those of Pitcairn descent) and there are many things being
planned. It will be a very interesting period.
To help celebrate the event the HIDXA Club has been issued with the special
callsigns of VI9NL and VI9NS for the whole month of June covering the period
of the celebrations. Kirsti VK9NL and I VK9NS will use these special calls
and will both try to be as active as possible during the period. For the
record, the HIDXA Club was created some 23 years ago after the return from
Heard Island, and is registered on Norfolk Island....'
73 Jim, VK9NS
VI9, NORFOLK ISLAND

Bill/VK4FW. Bill states, 'We have been very fortunate to have the use of our
special callsign VI9NI. This has been issued to help celebrate the 150th
anniversary of the landing of the 'HMS Bounty Mutineers.' Suggested operating
frequencies are
CW - 1822 3523 7023 10103 14023 18073 21023 24893 28023 and 50125
