Another DXpedition Rapa Nui Easter Island 2009



It is not easy to break in the pile-up that a DXpedition has, especially form a very desirable location. It takes time and patience, especially with a modest station and antenna. I had time to check the island out on Google Earth and boy, it is nice over there.

Today was the first time I heard the signals from XR0Y in Easter Island at a level where I knew I had a chance to make it through. Still, I'm battling big gun stations with mega antennas and amplifiers. The operator was first calling for European stations and giving a time later on for US ones. When they switched to US stations, there was a large pile up. I tried quite a few times to get through but was not lucky. The operator was working split,  transmitting on one frequency, listening on another five kH up on the scale. But when the pile-up grew too much he asked to spread the calls on 10kH and I happened to pick 8kH up for my Tx frequency. My call was answered very quickly and I sure hope I am in their log. I guess that knowing how to operate my rig, doing it fast and with a bit of luck, 100 watts made it through!

These guys are GOOD! Not only do they update their log quite often, they also use Twitter to announce it! Hats off! They really use every bit of technology at their hands to get information through. They definitively deserve some support!

CQ-WW-SSB 2009 Contest




I had lots of fun with this contest. It did not start well for me though. First, I had intended to give a trial run to the N1MM contesting logging software a week before that at teh NY QSO Party, but I was too tired aftera train ride and  a long day in Old Forge NY to operate my station let alone with new software. So when thsi contest came, I had not even prepared its logging file. So it took me a few minutes to do that and then things seemed to work out OK but I noticed some problems, with the software, including it not staying connected to my radio and thus not logging the frequencies correctly and a few more minor glitches. So I decided to revert to my trusted regular logging software, Ham Radio Deluxe and again it took me a few more minutes to set a new log up but then I was up and hopefully running. That first evening was disappointing, conditions were awful and I soon called it quits for the night, as I saw not reason to stay awake just for a few QSOs that I might be able to make. Things remained slow early in the next morning but started getting better as suddenly the 15 meters band opened, while the 20 meters was so crowded it was difficult to make calls there, unless you had am amplifier. I'm operating at low power, 100 watts maximum, single operator, non-assisted. So I made quite a lot of contacts on 15m. Things quieted down in the evening, again I saw no reason to stay awake overnight. I had 117 QSOs so far, not bad, kind of opening the possibility to beat my own 181 QSOs record. On Sunday, things got really busy on 20m and almost as busy on 15m. I got busy and in the afternoon I had beaten my own recors and now was forging ahead, setting a 200 goal, reaching it, setting a 225 goal and reaching it too. I finally set my sights on 250 QSOs and reached that goal with 15 minutes to spare in the contest. I decided to quit there, claimnig a score of 89206 points. Some calls are multipliers and the math is too cumbersome for me to figure it out, that's why I have a computer!

I ran into troubles with the Cabrillo formatted log I am to use to report my activity. Saving my ADIF file from Ham Radio Deluxe, and using adif2cabr to get the Cabrillo file, I lost a colums of data. Using the HRD ADOF file and importing it into N1MM, then exporting a Cabrillo file from N1MM, I got a file where the frequencies were not right, there were some mistakes in the file mainly in Canadian calls (15) but I had the missing column. So I Took the Cabrillo file I got from adif2cabr, imported it as text file to Excel, imported teh N1MM cabrillo file into a different sheet in Excel, copied the missing column from the N1MM cabrillo file and pasted it into the adif2cabr file in Excel. Saved that Excel file as a text file, used Note Tab Lite to check it, reformatted it a bit, just added some tabs for clarity (although the file would have read correctly, but I like my columns well aligned and send the file in. It was accepted quite easily by the robot.

Why did I write all this? Simply, so I'll remember next time, if I bump into similar problems and if someone else needs that information, I got it here.

Do I expect to win? Heck no! Some of the big gun stations amass millions of points. But I already have accomplished my goal, my score is yet higher than ever before, I've also found some ways to improve on my operation. I started controlling my transmission via computer, instead of the foot switch. Takes a lot less coordination and my dog can sleep at my feet without being distrubed. I also used VOX, voice activated transmission, but I have to be careful as whatever I say may be trransmitted, including what I say to my dogs oand/or wife...

I ran into enough problems with N1MM to scrub it and revert to HRD. N1MM is supposed to be a very good contesting software. I'll give it another trial at a more minor contest and see if I can use it efficiently. I know that some of the problems I had were due to user error. The 400+ pages manual doesn't help much, too much information when you need quick answers but I've found a few shorter versions that may just put me on the right track. I already found some answers to problems I had so it may be worth another look. Also, if I get it to log right, then the Cabriullo file export will be a breeze, something I really like, especially since now, I tend to ahve a log that is getting longer and more problematic to edit, even if just for formatting.

QSO with LU4GW from Trelew Argentina

Sometimes a short QSO in a contest becomes much more meaningful than a few more points or a multiplier. This happened to me with the short contest QSO with LU4GW, Jorge Omar Gallego from Trelew, Argentina. This was not my first QSO with Argentina, but it rang a bell. Trelew, I remember the name of that town! Why? As a child, been raised in France, I read books by Antoine de Saint Exupery and especially my favorite, Vol de Nuit or Night Flight in English. And Saint Ex wrote about Trelew in this book, a wonderful passage that I believe inspired me in becoming an amateur radio operator, years later, many years later. It is just after that LU4GW QSO that it all came into perspective. I found this passage on the web, did not like the English translation they had so I translated it on my own.


==================

Commodorio Rivadavia doesn't hear a thing anymore, but a thousand kilometers from there and twenty minutes later, Bahia Blanca catches a second message.
"-descending... Entering clouds".
followed by two words in an undecipherable text arriving at the post of Trelew:
"-Seeing nothing..."
That's shortwave. You hear it over there, but here we remain deaf. And then, for no reason, everything changes.
This crew whose location is unknown, already appears to the living as out space and time and the blank sheets of the radios logs seem to have already been written by ghosts.
Have they run out of fuel or does the pilot play his last hand to the breakdown: finding the ground without crashing?
The voice from Bahia Blanca orders Trelew:
"-Ask him"

The wireless radio listening post looks like a laboratory with nickel, copper, gauges and a network of wires. The night watch operators in white shirts are silently bend like over a simple experiment. With their dainty fingers they touch the controls and search the magnetic sky like dowsers of a gold-lode.
-"No answer?"
-"No answer!"
Perhaps they are going to pick up a sound that might be a sign of life. If the aircraft and its running lights climbed towards the stars they could possibly hear the chant of that star. Seconds pass, really flowing like blood. Are they still flying? Every second reduces the chance. The flow of of time seems to becomes destructive. Just as twenty centuries, affect a temple, make its mark in the granite and transform the temple into dust and here, centuries of usage conglomerate in each second to threaten the crew.
Every second takes something away. Fabien's voice, Fabien's laughter, his smile. The silence is gaining ground. An increasingly deep silence, falling on this crew like the weight of a sea. Then somebody notices: "One hour forty. Last drop of fuel; it's impossible that they are still flying".

And peace sets...

A taste of bitterness and insipidity surges to the lips, like the end of a journey. Something comes to an end, of which we know nothing, something rather distasteful. And the same gloominess that hangs in closed factories can be felt among the nickel and copper veins. All this equipment seems heavy, useless and abandoned: the weight of dead branches.
All that's left is waiting for dawn.
In several hours all of Argentina will emerge in daylight and these people remain here like on a shore with a net that is pulled, ... slowly pulled, and nobody knows what the catch will be.

DXCC progress

Well, it was time to have a look at my logs as I noticed that I have 55 confirmed entities with ARRL's Log of the World (LoTW). In addition, I have QSL cards for another 20 entities, so I'm three quarters of the way there in confirmed entities.

Checking my logs, I found another 28 entities so now I'm busy printing envelopes and filling-in the cards so hopefully, I will get replies and will be able to submit my claim for the DXCC, award for contacts with one hundred different entities and/or countries in the world.

The ARRL DX Century Club Program

Once I get enough cards back to complete 100 entities, I will have to take them to a Field Checker to continue the application process.

UPDATE

Well the cards are slowly coming in. Seven were waiting for me upon returning from the trip to Panama. Then three more came on different days, and today three came together. One of the card I got was a return, addressee not known, but upon checking with QRZ, it appeared there was a problem with the PO.Box, so this card is back on its way to San Marino.

So for April 2nd, I have now 56 entities on LoTW, and 31 cards in hand for a total of 87 entities. Thirteen more to go and seventeen cards sent out that have not come back yet.

Well we are now May 10th and the score has improved but not yet there. I currently have 59 LoTW entities and 38 cards in hand, for a total of 97 confirmed entities. Three more to go...

May 14th, I'm getting closer yet with one more LoTW entity, so now it is 60 LoTW and 38 cards in hand... I worked a Grenada station on RTTY and this one is a LoTW user so I was really hoping to get a QSL. Well, it worked and now whether the card I sent for a previous contact in Grenada ever comes back is more academic, although I'd like to have it anyhow.

Well, I'll be giving preference to LoTW users by using programs such as LUQ which identify them and they will become just as attractive as rare DX stations. While the DXCC is a goal I'm about to achieve, I see it now only as a stepping stone to things bigger and better.

May 20th. I just got another LoTW confirmation, this time for Kenya so now I stand at 61 LoTW and 38 cards in hand for a total of 99 confirmed DXCC entities. Oh the wait for number 100 is going to be long...

Made contact with K5D, DX expedition on Desecheo Island


February 13. 2009
Made contact with the K5D DX expedition over there.



Desecheo Island is located off Puerto Rico. It is a nature preserve and the Fish and Wildlife authorities don't allow people in there, so this DX expedition is a rare occasion to make contact with that particular location. It also gives me another entity towards my DXCC award given for confirmed contacts with at least 100 overseas entities and countries. Desecheo is the 6th most-needed DXCC entity world-wide! The 3rd most-needed DXCC entity in Europe! And the 2nd most-needed DXCC entity in Asia! So although it is not a very long distance call, 1,777 miles, it is an important contact for me. If you want to learn more about this DX expedition check out their webpage: http://www.kp5.us/

I worked my Icom 756ProIII, which is my main HF radio.


And here is a close up of the display.

Now the operator of the Desecheo Island station K5D was operating on a split frequency, meaning he was transmitting on 18.145 MHz but listening anywhere between 18.150 to18.160, or 5 to 10 up in the ham lingo. The trick is to find what frequency K5D is actually listening to so you can tranmit on that particular frequency and make the call. Of course you need to also listen to his transmit frequency. Most HF radios allow you to do that but the Icom 756ProIII not only has a split mode, it has a dual watch which allows me to listen to two frequencies at a time. Yes, it takes some getting used to figure it out in your head, but it is like fishing , you need patience and slowly move the dial to where the large mountain is, where there is a lot of transmissions. Then you need to find the match between the station calling and K5D answering to that station. Now all you can do is hope a stronger station with n amplifier and a huge antenna is not going to walk over your own transmission. Patience and luck do it! I was very lucky and got through almost immediately after I found the listening frequency.

On the display, the white line by the "m" in spectrum indicates the frequency K5D is transmitting one and the red line the frequency I am transmitting on. Each hump indicates activity on that part of the band.

And below is the log excerpt of K5D showing the contact that I made. Now I'll try to make additional contacts in different bands.

Worked All States (WAS)


Working a two-way contact with each one of the fifty states of the Union was a goal I set to myself after I upgraded to General. Contacts seemed to be easy to make at first. Then came the realization that having made the contact is just part of the job and it needed to be followed up by a QSL card. Envelopes, stamps, return address stickers, address sticker in addition to filling the QSL card (I still prefer filling them manually to putting a sticker on them too), all that amounts to a lot of work that took me away from the radio itself. Then I discovered ARRL's Logbook of the World, LoTW. After sending in my full log, I was nicely suprized with quite a lot of confirmed QSLs. Then Stephen Genusa came up with Ham Radio Deluxe Utilities and that practically automated the process with my logging program, Simon Brown's Ham Radio Deluxe. Now I just had to make contacts and hope they will log it on LoTW. There were a few states that eluded me for some time, Alaska, till I got my new antenna, the Cushcraft MA5B. Then came some western states such as Nevada and the mid-west as in North and South Dakota. For whatever reason, the entire north east was never heard till the day of a contest where I got all these missing states, including Delaware and Rhode Island in one weekend! Now I knew I had contacts with all fifty states and just needed to wait for the confirmations. The mailcarrier brought some, LoTW brought most. I ended up with 33 LoTW contacts and 17 QSL cards. The last card, the one from Rhode Island, came in just a few days before Christmas. I was ready, applied for the LoTW part on line, made the payment, printed the forms, and mailed them and my cards the very same day. The ARRL Awards Desk was wonderful and I got my WAS certificate before the year was over! Talk about fast turnaround!

So here it is, now proudly hanging on my wall. And now it is turn to get serious on the DXCC, my first 100 contacts with distant entities.
