EPC Russia DX Contest 2011.

2011-09-24T04:48:00.001-07:00

Dear Fellow PSK Contester,

The Russian section of the European PSK Club has the honour to invite radio amateurs from all over the world to participate in the EPC Russia DX Contest 2011. The objective of the contest is to establish as many contacts as possible between radio amateurs around the world and radio amateurs in the Russia by using the BPSK63 mode. Everybody can work everybody for QSO and multiplier credit. The EPCRUDXC is held every year on the first weekend of October. This year it starts at 04:00 UTC on Saturday 1st October, 2011 and ends at 04:00 UTC on Sunday 2nd October, 2011. The rules and other information can be found at the contest website:
http://www.epc-ru.ru/index.php?option=com_content&task=view&id=351&Itemid=113

Number Exchange: RSQ is not sent. EPC-Russian stations should send their EPC-RU number (4 digits) + Grid Locator, RSQ is not required (example 0262 KO95 separately). All the rest stations should send QSO number, starting 001 + Grid Locator, RSQ is not required (example 001 IO75 - Only separately). The recommended call is "CQ EPCRU TEST".

The output power should not exceed 10 watts on 160 meters and 100 watts on other bands. Recommended frequencies are: 160 meters (1.838 – 1.840 MHz), 80 meters (3.582 – 3.590 MHz), 40 meters (7.040 – 7.050 MHz), 20 meters (14.072 – 14.080 MHz), 15 meters (21.072 – 21.080 MHz), and 10 meters (28.072 – 28.080 MHz).

The 8th CIS DX PSK Contest 2011

2011-09-14T15:01:00.000-07:00

The 8th CIS DX PSK Contest 2011

The European PSK Club has the honour to invite the radio amateurs all over the world to participate in the CIS DX PSK Contest 2011. The objective of the contest is to establish as many QPSK63 contacts as possible between radio amateurs around the world and radio amateurs in the Commonwealth of Independent States (CIS). CIS Stations are all those stations having the following prefixes: 4J4K, EK, ER, EUEZ, R, RARZ, U, and UAUZ. Everybody can work everybody for QSO and multiplier credit. The CIS DX PSK Contest starts at 12:00 UTC on Saturday 17th September, 2011 and ends at 12:00 UTC on Sunday 18th September, 2011.

IMPORTANT: From this year every participant sends RSQ and his/her four-digit DXDA number. An example of an exchange for W6EPC from the State of California is 599 2053. Maritime and aircraft mobile stations should send an RSQ report and four zeros, such as 599 0000. You can find your correct DXDA number at the corresponding list [ http://www.eupsk.com/documents/dxda-list.xls ].

CIS stations get 1 (one) point for any single QSO. DX stations get 3 (three) points for each contact with CIS station and 1 (one) point for any single QSO with all other stations. QSOs with the same call sign are valid if they are made on different bands. All participants earn a multiplier of 1 (one) for each unique DXDA territory worked regardless of band. Maritime and aircraft mobile stations are not the multipliers. The final score is the result of the total QSO points multiplied by the sum of the DXDA multipliers. Scoring is the same for all stations.

We recommend MixW software [ http://www.mixw.net ] to be used in the contest. The required MixW contest setup files for easy and correct operation in the event are listed at R3BB website [ http://www.digitalrus.ru ]. Please download and read the complete rules of the contest at [ http://www.cisdx.srars.org/cisdxc.pdf ].

Vem aí AMAPA - PQ8XB e PQ8OP

2011-08-11T05:14:00.001-07:00

Domingo, dia 14 próximo, iniciamos a viagem para Macapá no Amapá para ativação da Ilha de Parazinho no arquipélago de Bailique SA045. Iremos eu, PY2XB e o Orlando PT2OP. Usaremos os indicativos PQ8XB e PQ8OP respectivamente durante o período de 17 a 25 de agosto, dependendo das marés. Vamos estar QRV em princípio de 10 a 40m em CW , RTTY e SSB. Na ultima sexta-feira houve uma reportagem no Globo Reporter sobre o Rio Amazonas onde aparece o arquipélago de Bailique na foz do Rio, e faz referencia à Ilha de Parazinho. Quem viu, vai se lembrar que a vida das pessoas é governada pelas marés de grandes amplitudes. Esta vai governar as nossas também. No Parazinho há uma reserva ecológica e operaremos de lá. Na pagina do QRZ WWW.qrz.com/db/pq8xb há links para dois filmes sobre a reserva.

A logística extremamente complicada, tanto que o Orlando foi a Macapá em Março apenas para "tentar" costurar as coisas. Vamos levar comida, água, combustível, bateria, um gerador reserva, etc para a reserva. O percurso compreende uma viagem de barco de 12 horas de Macapá à Vila Progresso em Bailique e mais 40 minutos de voadeira até a reserva. As marés interferem em todos os horários de saída e de chegada. Vamos ficar 2 semanas fora de casa para ativar a ilha apenas uma semana.

Há muito poucos radioamadores no Amapá, de maneira que esperamos dar um contato de PQ8 a todos que o queiram. Será valido também para os diplomas IOTA, DIB, DFB, WLOTA e ARLHS. No retorno para casa, se possível , vamos ativar a fortaleza de São José do Macapá, em Macapá por 1 ou 2 dias. Ai utilizaremos nossos indicativos /PQ8 para não confundir com Parazinho.

QSL para PQ8XB será via PT7WA e para PQ8OP via PT2OP. Informaçõe e LOGs, sempre que possível, serão postadao em www.qrz.com/db/pq8xb.

Durante os preparativos contamos com a ajuda de algumas pessoas que precisamos lembrar: Sr. Manoel Reinaldo da Secretaria do Meio Ambiente do Amapá, Policarpo - PY8JPS, Sandro - PQ8SL, Luciano - PT7WA, Ed - PY4WAS e Alex PY2WAS, sem prejuízo de outros que nos prestaram alguma ajuda.

Até lá

Waterfall "Splatter" & Overdriving

2011-07-01T06:05:00.001-07:00

Hi Group et al

I have been monitoring 14070 +/- for the last couple of months and so far have advise no less that 100 stations of excessively overdriving resulting in "SPLATTER". I have also where possible sent by email (qrz.com address) a file.jpg of the offending waterfall image. Most around 80% have reacted immediately and adjusted their settings and were subsequently fb signals. Some adjusted later after yet another station advised them of a 591 signal report but unfortunately there was a minority who either because they didnt believe the report or who were simply ignorant of the procedure to reset the parameteres required for a "Splatter" free signal. I have taken it upon myself (G3PGA) to continue this mission in the name of EPC and would like to request that an EPC member in every country do likewise and not to be shy in coming forward. I use a very polite macro to advise stations and hope that it would enable them to correct any overdriving issues....:-

Please check and reduce your computer audio drive so that your ALC level is at ZERO.

At this moment you are splattering very wide 591 591.

In excess of 500 hz wide causing QRM on a busy band.

Also please check your speech processor is OFF......

TU es 73 <CALL> de <MYCALL> *** EPC SPLATTER-WATCH *** bk <RXANDCLEAR>

I would then if any query follow this with a full script as follows:-

DR <NAME> <CALL> de <MYCALL>

The ability to set up your radio for psk modes comes with experience.

Many stations are finding the PSK modes popular but do not fully understand how to set up the computer and radio for the mode.

I hope the following advice will help..

The important thing to remember is that it is very easy to overdrive the radio with too much audio from the computer sound card causing QRM

and SPLATTER.... I find the following is a good way to start:-

1) Tune your transmitter to say 40 watts output to a good aerial vswr having made sure you have a clear frequency first.

2) Using the soundcard drive sliders ( Volume + Wave ) whilst keying the radio move them up or down to achieve just under the 40 watts

drive level. Or, use the rotary level control on Signalink types. If you push the drive level over it WILL splatter.

3) Check the ALC meter reading and if its any more that ZERO then reduce the soundcard drive sliders slightly to achieve the ZERO ALC.

This is very IMPORTANT and is the worst cause of overdriven signals.

4) Make SURE the speech processor is OFF.

5) Double check your interface is OK.

That's all there is to it and you will have a clean signal with NO splatter or excessive sidebands which cause qrm and spoil the mode for others.

I hope this will help you to set up correctly and you enjoy the mode as much as I.

Any query please ask. TU es 73 <CALL> de <MYCALL> <RXANDCLEAR>

Now if one station in every country acted as I do then the PSK modes would be a lot cleaner.

So, come on guys, volunteer for this action and feel free to use my <MACROS> or modify as needed.

Thanks es vy 73 de Mike G3PGA ( EPC SPLATTERWATCH )

Evite espalhamento - SPLATTER

2011-05-23T20:30:00.001-07:00

As a result of numerous interesting comments I offer the following in the best HAM spirit
as help to those that obviously need it. The follwing two paragraphs I gratefull acknowledge the text from Andy G3SVD an excellent explanation of ALC and SPLATTER:-

ALC is "automatic level control" and is a system applied to power amplifiers in order to force them to operate only in the linear portion of the operating curve. In a so called linear amplifier if you plot the power output against power input at the bottom of the graph it will be straight line, then it tends to curve off. The alc system takes a sniff of the output voltage and applies that back to the input as a negative voltage in order to reduce the gain of the amplifier as the out increases. The alc voltage can just be applied within the PA itself or it can be applied back to the driving device, ie transceiver. However this does have limits and if one really applies too much drive you can still operate outside the linear portion.

SPLATTER is caused when a PA is over driven and it is operating in the non-linear portion of the curve. This causes the PA to produce harmonics of the input signal which then modulate each other (inter-modulation) and these will produce signals outside the original width of the SSB signal. This also applies, of course, to PSK as it is a signal comprising two continuously transmitted tones. The splatter is what you can hear on sideband and see on the waterfall in PSK.

Thank you Andy....

Now for how I setup for PSK mode and note I have this setup as a macro to fire off at any time to assist a fellow ham with a problem setting up...

RESUMINDO. Operando modos digitais, ajuste sua transmissão de modo que o ALC, apresente indicação zero, ajuste para ficar ligeiramente abaixo de 1 (um)

PP0T - Trindade Island

2011-05-08T08:33:00.001-07:00

With support from the Cantareira DX Group, Junior PY2ZA will be
performing one of the longest ever expeditions in Brazil.

The Garcia D’Ávila (Navy ship) is scheduled to leave for Trindade on April 18 at 0800h local time. It is planned a journey of four days across the Atlantic. Landing scheduled April 22.

This expedition, due to the length of time on the island, has only PY2ZA – Junior, who wants to QRV on all HF bands & 6 meters, in SSB, CW, RTTY, PSK and maybe SSTV. There is also the possibility to participate in some contests.

During the outward journey (April) and back (June) Junior plans to be active as PY2ZA/MM on 6m using a portable transceiver.
