Comprida Island - Japy DX  View Printable Version 
Monday, January 07 2008



Hello,

The Japy DX Group made in the latest week one trip to Comprida Island
(GG68, Sao Paulo, Brazil) for VHF and UHF DXing. Following the log and
some informations:

1 - Despite the hours noted as "TEP Open" and "TEP closed", the
propagation did not show constant all over that period: sometimes
appears with 2 maximums, other times seems like one good first opening
to then several short good openings on the night;

2 - FM5CS was on 144,200 MHz in USB with distorted but strong workable
audio. We did this QSO point-to-point that covered 4600 km. When FM5CS
made QSY for FM we just noted the carrier with usual TEP effects
(fading, distortion, Doppler), unable to identify any word;

3 - We also heard the APRS QRG used in Carib but just for seconds, maybe
because the low traffic or the propagation indeed. In our old expedition
to Itapoah, Santa Catarina, Brazil, we daily listen these signals and
identify APRS stations from Martinique;

4 – Different of the latest DX Camp did in November, 2006, now we
clearly heard broadcasting stations in 88 MHz band that was not located
in Barbados only. They came from Martinique but in less time than all
opening to Barbados. For Brazilian Comprida Island, Barbados is the main
area in the opposite side of America covered by TEP;

5 - The station The One (Barbados) was the best reference for TEP. We
heard it for minutes after and before considering the others stations.
In the past we noted it with Hott FM (Barbados). In 2 meters the
Barbados repeater 146,910 MHz gave to us the best return signals to
our calls. By there we made the QSO with 8P6JB around 4400 km far.
Without beacons in 2 meters from Carib, it turned in one of our main
reference in the band. On 6 meters 9Y4AT was the louder and long time
beacon;

6 - However we could not achieve major conclusions because we stay there
for short time, with low number of transceivers and operators for
multiband monitoring. We have precisely and limited informations about
propagation behavior for what we found on that time with these stations
and locations;

7 - In 88 MHz band we used Degen 1103 and Sony 7600. In the first
receiver we worked with the jacket devoted for external antenna and in
the second receiver we used one simple system made by Mr. Martin Jenny
for radios that does not have that jacket for external antenna. The
difference was amazing considering the traditional way of listening
FM-DX in Brazil using only the telescopic antenna. Both receivers was
sharing the same antenna (Thevear 416-C Band 2) with one splitter;

8 - About Brazilian paths we had propagation to the interior of Sao
Paulo. In 88 MHz we heard stations 300 - 400 km far inside the
country. In 2m SSB we also heard stations from these areas but no
takers. Nothing on 432 MHz. The majority of the intra PY QSOS reach 200 km.

9 - As usual we went to the field with some simple HF and we heard 1A4A
at 21 MHz CW. Several USA stations on the pile up. The noise was quite
high for low bands so we did not made any NDB/LW listening.

Thanks a lot for who followed the skeds and spread the previous
informations about this portable station.

So check the LOG and till the next Japy DX outdoor operation!

Fw: Nepal em 6 metros EME  View Printable Version 
Monday, January 07 2008



Pela ZSVHF:

- - - - - - - -
Date: Sat, 24 Mar 2007 08:22:49 -0600
From: Lance Collister
Subject: [ZSVHF] 9N7JO on 6m

I am very pleased to report that I was able to complete Friday on 6m EME
with Pop, YU7EF, who is in Nepal until the end of next month and using
the callsign 9N7JO (in NL27qr). We had about 6 minutes worth of window
on my moonrise, and we completed in 3 minutes. We were VERY lucky that
the polarity was reciprocal for us both at the same time! His JT65A
signals were -24 dB here. It was my 60th country worked on 6m EME, and
new overall DXCC #112.

Pop is using one of the legendary ACOM 1000 amplifiers (running at about
500w output) along with a high gain 6 element homebrew antenna (YU7EF
computer optimized design)constructed from materials he could find over
there in Nepal. This was my first opportunity to run a sked with Pop,
and it was on his moonset, which seems to work quite well. We don't know
anything about his moonrise yet except that he has increasing horizon
elevation on azimuths greater than 90 degrees.

Anyway, the bottom line is that Pop has put together a 6m EME station
over there and it certainly is working! Congratulations to him for
overcoming one obstacle after another! And of course, many thanks to
K1JT, the developer of WSJT software (including the weak signal digital
JT65A mode), without whom such a contact would not have been possible.
It is GREAT to see so many more DXpedition operators including 6m EME in
their plans! Now that we are at the bottom of the sunspot cycle, we are
at the BEST time for 6m EME - the geomagnetic field is quiet and there
is very little extra signal scattering and degredation :-)

Good DX and 73 to all! Lance

�indows-1252?q?BPL/PLC na Austrália  View Printable Version 
Tuesday, February 27 2007



Oi turma,

Testes recentes sobre efeitos do BPL/PLC pela WIA (equivalente a "LABRE
australiana").

Fte: WIA News.

Flávio Archangelo PY2ZX
- - -

The Australian Communications and Media Authority (ACMA) performed
background noise and emission measurements at the Mt Beauty BPL trial in
Victoria, over the 20th-21st February. The measurements were in response
to an interference complaint lodged with ACMA by Ian Paul VK3LJJ.

Gary Smith- Manager BPL Projects Team Regulation and Compliance Branch,
and Colin Payne – Regulation and Compliance Branch Melbourne,
represented ACMA. Yoram Apter - Project Manager BPL, represented
SP-Ausnet, and WIA Director Phil Wait VK2DKN represented the WIA.

Background noise measurements were performed in various locations around
the township of Mt Beauty, following deactivation of the BPL equipment
by the service provider SP-Ausnet. BPL emissions and the effectiveness
of notching the BPL signal in amateur bands were measured after system
re-activation.

As expected high level BPL emission was measured in the trial area. The
maximum notch depth measured within amateur bands was about 35dB.
Background noise was higher than expected, highlighting the need for a
series of noise measurements over many days to accurately determine
typical background noise levels at any location.

Observations of BPL emissions received on Ian Paul’s amateur transceiver
and G5RV antenna were recorded by Phil Wait. Those observations confirm
that, in the vicinity of Ian Paul’s QTH, SP-Ausnet has notched all
affected HF amateur bands except for 10 metres. However due to the
higher than expected level of background noise on all amateur bands at
the time of the observation, notch depth could not be adequately
determined.

SP-Ausnet demonstrated new network control software that allows remote
notching of frequencies or bands of frequencies, in any segment of their
trial BPL network, from an office anywhere. It now appears relatively
easy for SP-Ausnet to quickly notch amateur band frequencies in response
to an interference complaint from an amateur.

As the maximum notch depth was measured at about 35dB, the WIA is of the
opinion that both software and hardware notching will be required to
adequately protect amateur radio operation from substantial interference
from BPL emission, and that should be the focus of further development
by BPL equipment manufacturers.

This measurement event also provided an ideal opportunity to compare
real-world data from ACMA’s measuring equipment and the FSM technique
developed by Owen Duffy VK1OD and Ed Hare W1RFI. We were able to
demonstrate close agreement between the two measurement systems, thus
confirming our confidence in the FSM measuring technique and our own FSM
measurement Jump-kit.

The WIA has now attended ACMA measurement events at Mt Nelson (TAS) and
Mt Beauty (VIC) BPL trials. It is apparent that all stakeholders
involved in BPL trials are now taking interference complaints from radio
amateurs very seriously, and are making changes to their BPL technology
and systems to improve the outcome for radio amateurs.

We would like to thank ACMA for their invitation to attend these
measurement events, and for their constructive working relationship with
the WIA.

Hello

Are you getting ready for a new season with loads of VUSHF DX-peditions?
Then take a look at VUSHF DX-peditions www.rudius.net/dxp where even
more information features have been added.

E-mail notification
-------------------
VUSHF DX-peditions can inform you through a tailored e-mail notification
system. A notification e-mail is sent when there is a new DX-pedition,
the information has updated, DX-peditions starting today, a weekly
notification etc. while taking your band and propagation preferences
into account.

This new features makes it relevant for you to register with VUSHF
DX-peditions even if you do not make DX-peditons yourself!

RSS Feed
--------
This feature is a Rich Site Summary/Really Simple Syndication news
system that has been in use by many newspapers for years. If you are
already familiar with feeds just add the URLs to your reader:

www.rudius.net/dxp/rss.xml
www.rudius.net/dxp/rss_begin.xml
www.rudius.net/dxp/rss_end.xml

If you are not familiar with RSS feeds it is a news reading facility
whereby you can collect the type of news you would like to follow and
from various sources - all into one place, your news reader. If you do
not have a reader you can pick up a free one here: www.feedreader.com or
try Google for other readers, some are free some are not:
www.google.com/search?hl=en&lr=&q=rss+reader

No enough to convince you? Stay tuned as more features are already planned.

If you haven't heard of VUSHF DX-peditions already it is a
"do-it-yourself."

You write and update messages and comments and publish them yourself.
