Zeroed in on another DXpedition……..
Yesterday I had a nice relaxing afternoon sitting at the 7610 checking out the bands. Solar conditions have been great the past while and that is a nice change to see. I was able to work 7P8RU again, and I did see the DXpedition HD8R from Galápagos spotted on DX summit . I was not able to hear them on 20m and barely on 40m, but then I saw them spotted on 17m. I found 17m to be very quiet, and I definitely saw HD8R on the waterfall but no pile up was being shown. I placed the Icom 7610 in Dual watch and split mode and found HD8R was working many stations, but most if not all I could not hear. The DX stations they were answering were mainly U.S. stations, so I realized the band was open in my direction. As I listened and I emphasize "listening". Now and then some U.S. stations were heard at my end working HD8R and this allowed me to get the team's strategy for working DX.
I blindly threw my call-out a few times, and very soon after I heard VE9KE 599....I came back with VE9KK KK KK and low and behold the call was corrected, and I was in their log. Once again 100 watts and my Endfed antenna came through for me.
This weekend is the CQWW SSB contest and for the SSB folks this is a big one. There is going to be lots of rare DX to be had for sure. For me I am a CW guy and not because I snub SSB but because in the past when operating SSB I have caused issues with neighbours. I am going to see if the rare CW stations have less of a pileup this weekend because of the SSB contest and many will be operating in that.
The art of working split to contact a DXpedition.
Contacting 7P8RU |
Yesterday afternoon while on 20m I noticed a large gathering around 14.040. After a little investigating, I found it to be the 7P8RU DXpedition from Lesotho located in South Africa. The team were excellent CW operators and this made for a very organized pileup. As I listened to find out how they were working the pileup I found that as always operators trying to contact 7P8RU on their calling frequency. With most if not all DXpeditions they operate split, meaning they call CQ on one frequency and listen on another. Their listening frequency can vary from 1kHz to 5kHz span.
I find it best to listen to the DX station and also those trying to contact the DX station. This is done to learn how the DX station is working "the pileup"..... those who are trying to make contact. Most if not always the DX station has a pattern on how they contact calling stations. Other times they indicate specific regions they only want to contact. It's best to listen first and find out the DX's rhythm, and also if they are working a region of the world that you are not in. This avoids you calling not getting answered and the DX station wondering why you're not listening to instructions. This just brings about frustrations at both ends.
Now down to the nitty-gritty of making contact! Once you have listened and found out the DX rhythm and that he is working stations in your part of the world, it's time to jump in the fray. But wait, how does one listen to both the DXpedition and perspective contact stations, who are 1-4 kHz away? This is where rigs with 2 independent receivers come in very handy. The 2 independent receivers allows you to hear VFO A and VFO B at the same time or the DX and those who are trying to contact them. In my case I use headphones with VFO A in my left ear and VFO B in my right ear.
They do say that a picture is worth a thousand words....and with DXpeditions this is also very true. It's great to hear both sides but adding a visual representation is fantastic! This is done with a radio that has a spectrum scope. Now you are able to hear and see each station the DX is working. As the DX either moves up or down the band, you can fit your signal in the pathway and toss out your call and see if you are heard.
The Icom 7610 has all the above-mentioned bells and whistles, as do many other HF and SDR rigs. The picture above is a screenshot of my 7610 setup to work 7P8RU. I have turned on "Dual watch" this allows me to hear both VFO A (main) and B (sub) Split has been turned on, so I transmit on VFO B and not on top of 7P8RU on VFO A.
On the spectrum scope, the red M is the main VFO A, and it is set on 7P8RU's calling frequency. The crowd of signals to the right (between M and S) are those calling the DXpedition station. The green "S" is my sub VFO marker and tells me where my transmit signal will be.
One nice thing about the scope, once 7P8RU has contacted a station, most times you can see this station visually answering the DX station. By watching this interaction you get an idea of how the DX station is working the pileup. The above picture shows the scope giving a band slice of 100 kHz and you can see t FT8 to the far right and toward the bottom of the band other CW signals. When working the DXpedition I have the scope set to a narrow slice of the band, so I can get a better picture of the pileup and who is being worked by the DX.
It's great fun to work these stations when you can hear them, and it gives you a good workout on learning your radio and what it can do. In my case 7P8RU was contacted and is in the log!
Travel Footage: 3Y0Z Antarctic Bouvet Island DXpedition 2018 Expedition (by EY8MM)
Here is video footage of the journey to Antarctic Bouvet Island, made by the 3Y0Z amateur ham radio team. This footage caught a few moments on the deck of M/V Betanzos.
As you can see in the last moments of this footage, the weather conditions contributed to the decision to abort the DXpedition, as it was far too dangerous to continue this expedition.
As reported by ARRL:
“Our captain has decided that it is in the best interest of safety and expediency to proceed directly to Capetown, South Africa, rather than Punta Arenas, Chile. We are now heading north to avoid the possibility of encountering ice. Currently, there is no ice in sight or on radar. In due time, we will head easterly toward Capetown. Our entire team is safe. Most are resting in their bunks and in good spirits. We will keep the amateur radio community and our families informed, as we continue our journey.”
In a huge disappointment for the DX community and the members of the 3Y0Z Bouvet Island team, the DXpedition’s leaders announced at 2000 UTC today (February 3) that a decision had been made to abort the DXpedition and head back to Chile.
“During the last 72 hours, we continued to experience the high winds, low clouds, fog and rough seas that have prevented helicopter operations since our arrival at Bouvet,” said an announcement on the 3Y0Z Bouvet Island website. “No improvement was predicted in the weather forecast for the next 4 days. Then, last night, an issue developed in one of the ship’s engines. This morning, the captain of the vessel declared it unsafe to continue with our project and aborted the DXpedition. We are now on our long voyage back to Punta Arenas. As you might imagine, the team is deeply disappointed, but safe. There is already talk about rescheduling the DXpedition.”
Bouvet Island currently is the third most-wanted DXCC entity, behind Kosovo and North Korea. The 3Y0Z DXpedition, comprised of top operators with considerable DXpedition experience, has been in the planning stages for 2 years and had attracted contributions from clubs and individuals around the world.
A dependency of Norway, Bouvet is a subantarctic island in the South Atlantic. The last Bouvet activation was 3Y0E, during a scientific expedition over the winter of 2007-2008.

Anonymous is getting very smart!
Happy to be back from the vet's |
maybe 2 or 3 "anonymous" postings a week. Now let me clarify what I mean my anonymous......these are advertisers trying to post a comment on my blog but the main idea is to plug their biz with a link! Blogger has been excellent with the ability to discern between the real deal anonymous comment and the...let me take advantage of your blog and plug my biz anonymous comment. Over the last month I have noticed a large increase of anonymous comments (the take advantage type) trying to use my blog. Not sure why this is.....my blog can't be all that popular? I really don't care if they "try" to post their fake comments but what I have noticed is they must be getting smarter in how they word the comment. Blogger is not recognizing it as spam but seeing it as a legit comment. These past couple of weeks I have had to go through my comment section of blogger and delete comment posts that are just plain spam! Has anyone else had this issue? Or do you have suggestions on how to deal with this?
A new antenna coming soon………
Mounted on bench |
So lets look at the nitty gritty of the antenna first off it's made by SteppIR who has a GREAT reputation and has been the choice of many DXpeditions. The 20m version extends to 9 feet and when folded up is only 26 inches. The 40m version is 18 feet and reduces to 30 inches. As far as I am concerned both sizes are very manageable for transporting. I am not gong to high light evey detail as there is a link on this post to the SteppIR CrankIR page with limited info but more to come!! This antenna is due to make its purchase date in the spring of this year. I did send an email to SteppIR with some questions about the antenna and Bart was very prompt to get back to me.
My Questions were........
1. I did not notice any radials are there any? (I asked this because for portable ops sometime radials can become a pain especially if you are in a park where the public is.)
Bart's answer was.....
The antenna will be designed to work with a single, elevated, tuned radial (included)
The 40 to 2m retracted |
Band conditions were great….if I was a SWL!!!!!
I would not advise this while driving but he did make the contact!!
I gave it a go and there was Chris loud and clear!! He was operating split and with my dual receivers in the K3 I was able to hear both sides of the adventure. It was great the band was not at all as busy as with 3B9SP so I gave him a go...and a go......and a go......until in the wink of an eye he was gone just replaced with static. Well that was my Thursday evening of ham radio. I will say I did have a blast and did miss getting on the radio.
