The last one!

They are already on the island. Tomorrow we will start hear them on the bands. Hopping that the propagation will help as it does with Ducie, we will work them to many bands. So warm the machines up! As for me this is the expedition that will complete my Honor Roll and for this reason I will love it and remember it the years to come. Here are their first words from the battlefield:
"We are on Clipperton Atoll! It's 0133z as we write this. We had a successful landing and have loaded quite a bit of our camp gear to the island. Our base camp is set up and we're all tired but full of enthusiasm! In the morning we will begin the construction of our operating stations on the north side of the island exactly where we had hoped to be able to land. We are excited about this as this location will provide the best paths for us to work the world. We will update this page in the morning in more detail but we wanted you all to know we are safe and are on the island."

Fireworks at Ducie Island!

Copying from Ducie page......

"On 2008 February 25 Monday at 0437z, after 13 days 7 hours and 37 minutes of continuous operation, RA0ALM contacted the Ducie Island expedition on the 10 MHz band for the expedition's 168,723rd contact.

According to documents maintained by Jari Jussila OH2BU, this contact breaks the record for the largest number of contacts made by any radio expedition. The record was previously held by the Five Star DX Association's expedition to the Comoros Island (D68C) during 2001 Feb 8-28.

A few moments later, the pre-moonrise starry skies above Ducie Island sparkled with a barrage of flares launched from the deck of the M/V Braveheart in celebration. The thirteen operators and six Braveheart crew congratulated each other with handshakes, hugs, and some strong coffee. But deep pileups of European and North American stations were still calling. Soon the seven on-duty operators were back in front of the radios, while the others crept off to their cots to catch up on sleep in the cool of the evening.

The Ducie Island expedition has broken other expedition records in recent days, including:


  • largest number of RTTY contacts, previously held by the Swains Island N8S expedition of 2007 April.
  • largest number of SSB (voice) contacts, previously held by the Comoros Island D68C expedition.
  • largest number of contacts on the 40m band, previously held by the Libya 5A7A expedition of 2006 November.
  • largest number of contacts on the 30m band, previously held by the St Brandon Island 3B7C expedition of 2007 September.
  • largest number of contacts on the 17m band, previously held by the Swains Island N8S expedition.
  • largest number of contacts with North America, previously held by the Comoros Island D68C expedition.
  • largest number of contacts with South America, previously held by the Peter the First Island 3Y0X expedition of 2006 February.
  • largest number of contacts with Africa, previously held by the Rodrigues Island 3B9C expedition of 2004 March-April.

As this message was transmitted by Iridium satellite from Ducie Island, the expedition contact total crossed 170,000 contacts... and continues to increase at about 415 contacts per hour. Most contacts now entering the logs are with European stations during their morning twilight period. In an hour or so the focus will shift to North and South America, east Asia and the Pacific, where it will remain until dawn at Ducie Island."

Congratulations dear folks. You gave us very nice moments indeed. And now next station Clipperton...the terminal one!

Ducie online log promised today

Actually it was booming on 80m this morning. The online log first upload is promised for today at noon. I am publishing some late news as they request it.

News #14- 2008 Feb 13

I just had a telephone call with Carsten (DL6LAU) on Ducie Island. The reason we did not get any update or online log from the island is that they had no time until now because of a big workload to setup the stations and antennas. They plan to go "online" in the next 6-12 hours so we expect the first online logs around noon on Thursday. Please be aware that the data connection via Iridium is very sensible so it can last a long time to upload the online logs.

After 1,5 days of operation they have now about 28,000 QSOs in the log (about 17,000 after the first 24 hours!). They already started RTTY operation on 20m with over 700 QSOs at the moment. In some days we expect also RTTY operation on 30m.

Antenna construction is still in progress. Some antennas for 12m and 10m are missing. Today they are at the installation of the Beverage antennas for the low bands.

All team members are in a good shape (except some sunburns) and they have a lot of fun. A problem is the extreme heat during the daywhich makes it nearly impossible for the night operators to sleep.

Tomorrow we will get some more news from the island. Please stay tuned.

We would be delighted if DX editors would publish this information as widely as possible and DXers bring it to the attention of their clubs and fellow DXers.

WPXRTTY TEST

I spent last weekend running the CQWPXRTTY contest. As a single operator I was 30 hours active chasing mostly dx stations. It was a really cold weekend, so I enjoyed it very much sitting all that time in my cozy shack. Even with a spotless sun propagation was not bad. MixW worked faultlessly again. I worked 605 qso and over 600,000points. No bad at all. The main target was not the championship of course. In comparison I had done 532 qso in CQWWRTTY last September. Several USA, VE, JA and VK stations were heard. P40X was in the log also. A welcome surprise it was also the qso with my friend Patrick, F6IRF. Patrick is a devoted CW operator so I did not expect him to join the test.

By the way two new expeditions start this week: VR6DX (Ducie) and TI9KK (Cocos). Both have nice signals in 80m and 40m in the morning, but no chance the rest of the day. With so low sun activity it is amazing we can work them. So no complains….and the next month I am anxious to work the TX5C (Clipperton). This is a very important for me as it is the real last one to get the Honor Roll with 329 entities. So folks it will be a really exciting spring.

New Year, New Gadgets in the shack

Every new year comes full of promises for dreams fulfillment. But some time you have to help a little bit to make this true. I think that gadgets are actually extensions of ourselves. You choose them for specific reasons. You feel more complete and more confident just using them in the every day routine. It is a kind of sophisticated toys for adult.But let me tell you what is this little introduction all about: Just to present you my new gadgets.

1. My new weather station. It is a DAVIS Vantage PRO2 wireless. All sensors are integrated to one unit and transmit data to console in a very efficient way. (First and only weather station in its class to use frequency hopping spread spectrum radio technology to transmit weather data wirelessly up to 1000' (300 m)).
I installed the ISS (Integrated Sensor Suite) up to my terrace just under my HF antennas. Fortunately the whole system turned out to be RF proof, an issue that my old Monitor II suffered a lot. The isolation between sensors and console protects the later from static that under bad weather conditions make provoke severe damage. But a weather station without a data logger and proper monitoring software it is absolutely useless. DAVIS has made great job on this part too. Data logger keeps data for 50 days if you choose one record every 30 min (there are many options upon this interval). WeatherLink, as they call the provided software, it does very well its job and can convert the older data bases to the new format. This weather station is a really mature product and quite compatible with HAM environments.

2. My RigExpert AA-200 Antenna analyzer. To say the truth I have not test this instrument as much as I want. First impressions are very good. I have to say that it is very good looking and gives the feeling of a well and toughly manufactured item. It is powered by a rechargeable Ni-MH battery pack 1800mAH and it has autonomy of 2 hours of continuous metering or 20 hours in stand by mode. It can also connected to a PC though a USB port. Connected to a dummy it gave me a R=50.1Ohm and reactance 0.2Ohm. My trapped dipole for 40m and 80m gave me this nice SWR diagram centered to 7080KHz. Magnify to see details. No bad, isn't it? If it is so accurate as I expect this is the ultimate tool for the serious amateur. Anyway I will come back with full review when I have much more measurements.

3. Finally I will add a small review for my ACOM1000 linear amplifier. This is not quite new but it need some time to test a linear.
What can I say about this state of the art piece of radio equipment? There are so many good reviews that I feel I have nothing to add. But let me do just a few simple comments. I work with it more than six months. I have participated in several contests during this period. Among them there were some very demanding ones, as CQ WW RTTY for example. Lots of hours of continuous working without any complain. Every time I am sitting in my shack beside my ACOM1000 I feel proud and full of confidence. Before I get it, I knew that it had a very good reputation, but my cohabitation with it, it is beyond my expectations. What are its hot features?
a. Absolutely silent (whisper fan, vacuum relays)
b. Very easy tuning (attenuator in order to tune with full driving power)
c .Withstand 3:1 SWR transmitting with full power (no external tuner required)
d. Excellent liquid crystal control monitoring 12 parameters
e. Very smart and efficient protection circuit
And some words about service. I need it only once. A minor problem resolved in a couple of days. People in ACOM are very friendly and really helpful. Simply the best service I have ever experienced in my 30 years amateur life.

At last sun wakes up

I am transferring comments from NASA information site about space weather. There is clear evidence that cycle 24 begun. Ladies and Gentlemen enjoy it.

Jan. 10, 2008: Hang on to your cell phone, a new solar cycle has just begun.

"On January 4, 2008, a reversed-polarity sunspot appeared—and this signals the start of Solar Cycle 24," says David Hathaway of the Marshall Space Flight Center.

Above: Images of the first sunspot of Solar Cycle 24 taken by the NASA/ESA Solar and Heliospheric Observatory (SOHO). [Larger image] [Movie]

Solar activity waxes and wanes in 11-year cycles. Lately, we've been experiencing the low ebb, "very few flares, sunspots, or activity of any kind," says Hathaway. "Solar minimum is upon us."

The previous solar cycle, Solar Cycle 23, peaked in 2000-2002 with many furious solar storms. That cycle decayed as usual to the present quiet leaving solar physicists little to do other than wonder, when would the next cycle begin?

The answer is now.

"New solar cycles always begin with a high-latitude, reversed polarity sunspot," explains Hathaway. "Reversed polarity" means a sunspot with opposite magnetic polarity compared to sunspots from the previous solar cycle. "High-latitude" refers to the sun's grid of latitude and longitude. Old cycle spots congregate near the sun's equator. New cycle spots appear higher, around 25 or 30 degrees latitude.

The sunspot that appeared on January 4th fits both these criteria. It was high latitude (30 degrees N) and magnetically reversed. NOAA named the spot AR10981, or "sunspot 981" for short.

Sunspot 981 was small--only about as wide as Earth, which counts as small on the grand scale of the sun--and it has already faded away. But its three day appearance on Jan. 4-6 was enough to convince most solar physicists that Solar Cycle 24 is underway.

Strange but True: While Solar Cycle 24 has begun, Solar Cycle 23 has not ended. Both cycles will coexist for a period of time, perhaps a year or more, as one dies down and the other comes to life. In the months ahead we may see old-cycle sunspots and new-cycle sunspots on the sun at the same time.

Confusion

Just a few days before Xmas Holidays ARRL gave us a present. A new entity for the DXXC! And what is the name of the baby? St Barthelemy island with prefix FJ. The activation was immediate by OH2BH and OH0XX and the call FJ/OH2AM shows up. These old wolves knew better what would happen and they were ready.

But the question is how many entities are they now in the DXCC list? It seems that neither ARRL really knows yet. As you can see in this page extract ARRL gives two different numbers (337 and 338). What is the correct one? You have not to worry a lot about this. Make the contact and you will know later the answer.
