Press Release 6

Press Release 6 : Mar 20 , 2011

VU4PB was hit by a noticeable pirate operation on 40m CW between 1527z to 1817z on 16th March 2011. This was at a time when our 40m CW station had gone off air at 1527z. All DXers please note that QSOs with VU4PB made during the above period was by a Slim Op. We understand the pain this news will cause and hope you can make QSOs on 40m with the real VU4PB soon.

We would also like to say that three of our key operators have been unable to join us at VU4PB as planned due to health and family issues and we have been working hard to fill the gaps with the operators that we have.

Stay tuned and do lookout for us

Press Release 5 : Mar 18 , 2011

VU4PB has now been operational for 3 days. The unusually bad weather has been challenging. Having to frequently check if your antennas have not been blown away by the storm force winds tends to slow things down!. Band conditions have not been ideal either with a lot of QRN.
However this morning the weather seems much better so the pending low band antennas will be put up. Listen for us on 80M and 160M tonight.

The Online Logs have been posted on the site for the period upto 17 Mar 0800Z.

We request operators who have confirmed QSO's in the log to not try again on the same band so as to allow others to have a shot.

A few members of the initial team leave today and we await additional operators on the 21st.

Stay tuned and do lookout for us

Press Release 4 : Mar 15 , 2011

VU4PB is now operational but due to very bad weather with high winds and rain only two stations were installed and ran on both 20 and 40m. We hope to get a third station operational by the end of the day today and the fourth later during this week.

Low band antennas will be up and running later in the week. Murphy is keeping us good company along with the daily storms.

Please note that our Operating Frequencies have been updated to avoid interference to the JA Emergency Nets which have been notified and our Propagation Page has also been updated.

The online logs will be available by 17th March.

Stay tuned and do lookout for us

Press Release 3 : Mar 11 , 2011

Eleven operators, from diverse parts of India, all getting together for the excitement of a DXpedition, are all set to fly out on Saturday the 12th March 2011,arriving in Port Blair around noon.


The others join us in a couple of days as they are also coming from different parts of India.


Much of the equipment was already sent by sea freight and has been received at Port Blair and waiting for unpacking and deployment to the three sites.


Some items missed the last sailing and have gone out via air freight.


It will be a busy three days before the stations go on the air.

Stay tuned and do lookout for us

 


 

VU4PB Propagation

Propagation to VU4 - March 2011

March 2011 offers DXers an opportunity to work VU4 which is #29 on the most wanted countries survey by the DX Magazine. Propagation predictions from VU4 to various areas of the world are given below.

With the path to North America being the toughest, detailed short path and long path predictions are given to seven geographical areas in North America. All other areas of the world should fare well using just short path.

Assumptions for the predictions are:

  • Mode: CW
  • Transmit power = 100W on all bands
  • Antenna gain = 0dBi
  • Noise environment = Residential
  • Minimum angle = 1.5o
  • Signal-to-Noise Ratio (SNR) = 0dB in a 500Hz bandwidth

Your specific openings may be longer or shorter than the predictions depending on your transmit power, your antennas, your site, and your noise environment. Openings will be a bit shorter for SSB due to needing a higher SNR than what is assumed in these predictions for CW.

Detailed predictions for 160m and 80m are not given - the team has an indicative inputs on what to look for when. The times of possible propagation on these two bands are determined by the times when the desired path is in (or very near) darkness. These times can be calculated from your specific sunrise and sunset times and the sunrise and sunset times at VU4.

We will be also watching the high bands to NA given the reports of recent QSOs from there to HS and surrounding areas.
