Good morning/evening it is Sunday the 16th of April 2006
and here is ANARTS with our weekly RTTY broadcast bringing
you - cast 1392.
We transmit on 40 metres 7042 each Sunday morning at 0030
UTC and 80 metres 3542 each Sunday evening at 0930 UTC.
Selected items from this cast are also transmitted by
the Westlakes Amateur Radio Club. Time of transmission is
1930 local time on Tuesdays and the frequency is 146.775MHZ.
ANARTS now has a web site at www.anarts.com.au

Propagation of Radio Waves.
Introduction, continued.
The intensity of a radio wave is measured in terms of the voltage
stress produced by the electrostatic field of the wave, which is
normally expressed in microvolts per metre (uV/M).
This strength in microvolts, is also exactly the same voltage as
the electromagnetic flux of the wave induced in a conductor. For
example, an antenna, one metre long when sweeping across the
conductor with the velocity of light.
The minimum field strength required to give a satisfactory reception
of a radio wave varies with the amount of interference present. Under
favourable conditions, field strengths of less than 1 uV/M will
produce intelligible signals.
Much greater field strengths are generally necessary however, because
of interference waves generated by man-made and natural sources.
In rural areas, experience has shown that it normally requires a much
lower field strength to ensure good reception at all times than is
required in urban areas where man-made interference is much greater.
This is one of the arguments for remotely locating the receivers of
commercial or communication organisations.
Ground and Sky waves.
The energy radiated from a transmitting antenna located near the
earths surface can be conveniently divided into Ground and Sky waves.
The Ground wave represents the energy travelling along the surface
of the earth, and its behaviour depends on the frequency and
character of the surface involved.
The Sky wave on the other hand represents the energy radiated at an
angle above the horizontal, and its ultimate behaviour is determined
by the ionised regions in the upper atmosphere.
Next week we shall look more closely at the Ground wave and in the
weeks ahead, the much bigger subject of Sky waves.
For information, in RTTY mode, I cannot express Microvolts per Metre
correctly, the u is actually the greek character Mu, and uV/m is the
closest RTTY will allow.

ANDAMAN ISLANDS - VU4: VU4AN will be the "prefix" for the 18-25 April
activities from the Andaman Islands. All licenced operators will have
a VU mainland callsign that will be prefixed with VU4AN/. For a list
of operators/callsigns check
http://www.niar.org/hamfest/participants.html.
AVES ISLAND - YV0: YX0A is expected to hit the airwaves on 19 April
and stay there until 1 May approximately. Check these frequencies for RTTY:
3570, 10137, 14085, 18100, 21085, 24920 and 28080 kHz. QSL via KU9C.
MONGOLIA - JT: Several Italian hams will operate from Mongolia 19
April to 8 May as JT1Y from Ulanbaatar and as JT0Y from Oigij using CW, SSB,
RTTY and PSK. QSL via I0SNY.
SYRIA - YK: N5FF, Saad plans to be active as YK1BA from Damascus 17
April to 5 May. He will operate in his spare time on HF using SSB, CW and
RTTY. QSL via homecall.
VANUATU - YJ: Guenter, DL2AWG will operate from Port Vila April 19 to
May 1. Look for him on 10-40 metres SSB, RTTY and PSK. Callsign might be
YJ0AWG or YJ0WG. QSL via DL2AWG.
The VK2SG RTTY DX NOTES are distributed every week via the
Winlink network, and are also available on the Internet at
URL http://mailman.qth.net/mailman/listinfo/vk2sg-rtty
and the digital-dx reflector.
To subscribe to the digital-dx reflector, send an e-mail

The Ohio/Penn DX Bulletin - excerpts
6W & J5, SENEGAL AND GUINEA-BISSAU
Peter, HA3AUI, has announced that he has prolonged his stay in Africa and will
now be active from both from Senegal (as 6W/HA3AUI) and Guinea-Bissau (as J5UAP)
until June 10th. Look for activity on 20/17/15/12/10 meters, SSB, with some
possible PSK and RTTY. He was heard this past week from J5-land on 20 meters
RTTY. QSL via his home callsign direct only.
8Q, MALDIVES (Correction/Update)
Simon, M0BOX, is now active as 8Q7BO from the Kuredu Island Resort (AS-013 --
not AS-018 as mentioned last week..), now through April 20th. He was heard on
PSK Sunday on 15 meters around 1023z. Look for activity during his spare time on
all bands 40-10 meters, the WARC bands included. Simon will concentrate on the
digital modes, mainly PSK31 plus RTTY and maybe SSTV if requested, and of course
SSB. Further information and updates can be found at:
http://www.btinternet.com/~m0box/

C9, MOZAMBIQUE (Update/Still Looking For Ops!)
Frosty, K5LBU/C91CF, announced that they now have one CW and one SSB operator
signed on for the Dxpedition to Mozambique this June-July. They will be there
and on the air from June 29th to July 13th. He states that they would like to
have at least 2 more operators join them. They plan to be in the IARU Contest.
They will also operate on EME on 6-2m and 70cm and plan to do PSK and RTTY in
their spare time. They hope to have 2 statons set up but need 2 more CW and one
more SSB operator to make it worth their effort to do both. Check out the Web
site to see the location they will be staying at:
http://www.tdxs.net/C9.html
Frosty will be in Visalia for the International DX Convention if you would like
to talk to him. Or you can call him at home at 281-437-1978 after 5 PM DST.
HA, HUNGARY (Special Activity)
Since March 29th (2006), the Hungarian amateurs can use 50-52 MHz. To celebrate
the long-awaited legalization of that band, the special callsign HA50MHZ will be
aired by Chris, HA5X, through December 31, 2006. Look for this special callsign
on CW/SSB and the digital modes. A short-term award is also in preparation, so
work as many HA/HG stations on 6m as you can. QSLs for HA50MHZ are via HA5X, the
LoTW or eQSL.
HH, HAITI
Operator Glauber, PS7EB, will be active as HH/PS7EB between May 19th and
November 25th. Glauber works for the Brazilian Army and has joined a group of
Brazilian Military Forces that will work together with ONU on a peace program in
Haiti. He will use an IC-746 PRO and a vertical multi-bander antenna and hopes
to be active on both modes CW/SSB and also the digital modes. QSL via PS7EB,
direct (QRZ.com) or by the Bureau. For direct QSLs, please enclose SASE + 1 USD
(or 1 IRC).
IOTA NEWS
Rag, LA6FJA, will operate as DU1/KI4KJP from Luzon Island (WLOTA LH-0081),
between now and May 1st. Activity will be on 80/40/30/20/17 meters CW, SSB, RTTY
and PSK31. QSL via WY4N (QRZ.com).
SA-NEW. CANCELLED! Zoli/HA1AG and Marco/CE6TBN were expected to activate a new IOTA this past weekend, but operations were cancelled due to WX and sea
conditions. The island was to be Pupuya Island in the O'Higgins/Maule Island
Group of Chile (group E under Chile in the IOTA Directory). The callsign was to
be XR4PI. Detailed information about the island can be found at:
http://www.hg6n.hu/ha1ag/xr4pi

SPECIAL EVENT
Members of Sala Consilina ARI team will operate from April 15th to May 15th with
the special callsign IO8VAT to celebrate the 75 years of the foundation of
Vatican Radio. Receive a special QSL card via the bureau from IZ8AJQ or direct
from: ARI, P.O. Box 11, CAP 84036 Sala Consilina (SA), ITALY.
YK, SYRIA
Saad, N5FF, informs OPDX that he has postponed his business trip to the Jordan
(JY) and has decided to proceed with his YK trip earlier than planned. He will
arrive in Damascus on the evening of April 16th, and should be active again as
YK1BA from April 17 through May 5th, returning home to Texas on May 6th. As
usual, the purpose of the trip is not a DXpedition, so his operating will be
sporadic. However, Saad hopes to be able to operate at least 3-4 hours a day.
Saad states, "With the current band conditions, I don't have a solid plan as to
what bands I will be operating on. However, I will operate on whatever bands
(80-10m) and modes that have the best propagation at the time." He suggests that
the most probable operating times are between 0100-0400z, 1900-2200z and
possibly 1100-1400z. Modes of operations will be on SSB and CW, but he will do
his best to work as much RTTY as possible also. QSL via N5FF.
YX0, AVES ISLAND (Update)
Members of the Association of Radioamateurs of Venezuela (ARV) and the Grupo DX
Caracas (GDXC) will activate Aves Island (Isla de Aves), on April 19th for two
weeks (if everything goes as planned, no promises here because they depend on
the Venezuelan NAVY for transport- ation and the landing permit). See details in
OPDX.753. Jose (Joe), YV5LIX, announced this past week that he will be the
DXpedition's digital modes coordinator for the YX0A operation. Modes will be
RTTY, PSK31 and PSK63.
