3G0YA in the log on 20m CW.
The other day I joined the 21st century loaded Ham Alert on my iPhone and set up Easter Island. On the first attempt to enter 3G0YA into HamAlert, I did not add a CW only and was flooded with digi and SSB spots. I managed to check out some YouTube videos and got that organized. Up to this point, I have been hit and miss using the DXheat cluster with no luck. I have never been able to hear them just the pileup they were working. Well, yesterday morning Ham Alert told me to head over the 20m, I did that and there they were but only at S1. I waited and then they bumped up to S4 and away my call went out onto the waves of opportunity.
In the past, I have been hoping so badly for a DXpedition station to hear me so felt I somehow heard part or all of my call. To only let down that I was not actually in the log once I checked. Hearing my call was only my ambitious imagination. This time when I dropped my call I was not sure if I heard or maybe imagined I heard my call. As Murphy would have it they went from S4 to S1 with their comeback to me. I listened and maybe heard again VE9KK 5NN.....so what the heck I tossed out my 5NN TU.
I continued to listen and wow for a few moments they were S6 or more so I tried again and this time I was sure I made it in the log. They called back "VE9", I tossed my call again and they came back "VE9KK 5NN" The funny thing was when I checked Clublog I found I was in the log the first time and it was not Murphy playing with me.
Taking the side road……
This weekend the LZ dx contest was up and running, I have never taken part in this contest and I was pleasantly surprised by the amount of activity. It's a 24-hour contest that started at 8 am out my way and it gave me a nice workout for the upcoming weekend for the CQ World Wide DX CW contest. I took part for about a total of 4 hours and made 120 contacts for a score of 13,110.
Midway into the contest I was taken down a side road for a pleasant surprise. At some point on Saturday afternoon calling CQ contest was slowing down on 20m. I decided to make a left turn and head down the 10m side road. There were very few LZ contesters there but I did notice a commotion on the waterfall. When I went to investigate it was H44WA DXpedition in the Soloman islands calling CQ North America (CQ NA) and he was all alone. I put the Icom 7610 in split and dual mode (hearing both VFOA and VFOB) and made the mental change from CW contesting to CW DXpedition. After a few short tries, I was in the log. I was glad I made a left turn and took a side road from the contest.
A pleasant surprise….
From time to time over the past week, I have seen 3B7M dxpedition spotted on the DX Heat Cluster and most of the time I either did not hear them or they were at or below the noise floor. I knew they were there as the pile-up was alive and well and responding with their call signs hoping to make it into 3B7M log. Yesterday they were spotted on 15m at their usual CW watering hole of 21.005 and as with all dxpedition they were operating split.
Before setting up my radio in split operation I wanted to make sure I could hear 3B7M. As I listened they did top out at S4 at times and that was good enough for me to give them a go. With my radio configured to split operation the next task was to watch my waterfall and see who 3B7M was contacting. With VFO A in my left ear (3B7M) and VFO B in my right ear (the pileup) I paid attention to who 3B7M was calling and then looked at the pile up on the waterfall to see the lonely signal that was coming back to him. The problem here was call signs not even close to the one 3B7M was calling were throwing their calls out again.
It took about 10 mins to figure out where 3B7M was dropping his call, now having said that there are a lot of radios with waterfalls out there now and they too have ferreted out 3B7M's pattern. Now the game is to figure out when we're exactly to drop my call. Most of the time it's just luck that you drop your call at the right time and right place! There are times in the waterfall you see stations running a KW or more signified by a bright red line on the waterfall as well as splatter. During those times I just rest as there is no use jumping in and getting nowhere.
It took about 20 minutes but I did finally hear 3B7M call "VE9KK 5NN". Now call me a bit skeptical but I have had times when I think that was my call or just one close to it? So I never get too excited until I check their online long which most dxpeditions have now and see if I am in it. This morning I checked and there I was in the log.
Finally, I am not sure why but there seems to be a new operating practice when it comes to dxpeditons and that is DQRMing (deliberate QRMing) In the past there have been those who forgot to put their rigs in split and transmit on the dxpetions calling frequency and I have been guilty of that! Also, those by mistake are tuning up their amp on top of the dx station as well. BUT recently I have unfortunately witnessed outright DQRMing. In the case of 3B7M I heard stations sending a series of fast CW dits over top of 3B7M or sending a series of the letter "V". I am almost positive they were intentional as this QRM was only sent when 3B7M was sending out a call sign they were seeking to make contact with. The DQRM was consistently dropped at just the right time each and every time. Fortunately, they grew tired of their childish behavior and moved on to something else.
For those Icom 7610 owners a different way to work split.
Fixed mode with 20kHz span |
I have had my Icom 7610 for several years now and am still very much enjoying it. From time to time I enjoy working DXpeditions and having Dual receivers and dual spectrum scopes with the Icom 7610 is very handy. The spectrum scope has 2 tuning options which are fixed and center modes. It could just be me but I find center mode hard to follow were as fixed mode seems very easy to follow. When you come across a station that is working split more often than not it’s because there is a large pileup and it’s more efficient to work split. For those readers who are not certain what split operation is this LINK explains it better than I can.
During split operation especially with a very rare DX station, there are LOTS of operators trying to contact the prized DX station. For this reason on the DX’s listening frequency, there are many ops trying to make contact. When you as an operator want to get involved and try to contact the DX station you have to drop yourself in the pool of stations calling the DX station.
The trick is where to set your VFO dial to have a chance to be heard by the DX station. In most cases, the DX station has a routine to move up or down his listening frequency which is your transmit frequency. One must listen and watch the waterfall to see who the DX station is answering call after call. You can then get the idea if he is moving up or down his listening frequency and by how much.
As I said there could be lots of callers and this translates to a very crowded waterfall display. To find out where to drop your call one must have a closer look at the waterfall. When this is done you can get some separation between the calling stations. Thus allowing you to better see who the DX station is answering. Then you have a good idea when and where to drop your call and hopefully be heard.
As I said the center mode I find very confusing and when I use it in split mode and spin the VFO I am just lost as to who is where and for this reason I use fixed mode.
As a side note: In center mode when you spin the VFO the signals on the waterfall move and the VFO marker remains stationary. In center mode when the VFO is changed the waterfall signals remain stationary and the VFO marker moves to the next signal.
As was said earlier it is best to have a closer look at the waterfall to see the action. In fixed mode, the smallest slice of the band you can have is 20khz. When operating CW as I do this for me is not enough for a very crowded calling group. In center mode, you can get a slice all the way down to +/- 2.5kHz or +/- 5kHz. For me, these are great options and with CW I generally would choose +/-2.5kHz but the rig has to be in center mode and that just does not work for me.
I have found a workaround so I can use the center mode, select +/-2.5kHz and still have the moving VFO B marker and not a moving waterfall! Below are the setup steps I take to make this happen.
In fixed mode, I find the DX station with VFO A
I then press the Dual-W button
Then press and hold Dual-W button to get the settings for VFO B the same as VFO A
I then press the split button
I press the Dual soft key my scope becomes over-under as this is how it is setup. You can see the dual scope view in the post pictures.
I change both scopes to center mode if not there already.
I now set the span to the same on each lower and upper scope in my case it is +/-2.5kHz I then touch VFO B frequency readout on the upper band scope (to activate VFO B)
Now in the upper band scope, VFO A remains stationary on the DX station. VFO B (in the upper band scope) now moves when the VFO dial is turned. The VFO marker moves (like fixed mode) and the band signals remain stationary.
The lower scope is still there but I don’t pay any attention to it. I found if I did not stay in dual scope mode I would lose the CENTER mode for VFO A and FIXED mode for VFO B.
5+/-kHz in center mode but VFO acts like fixed mode |
Now with all this said I just know there is going to be a comment that informs me I can press 2 simple buttons on the rig and get the same results. I seem to always take the long way around with things. I have added some screen pics of how the waterfall looks when in 20kHz, +/-5kHz and +/-2.5kHz span during a DXpedition. As you can see when in +/-2.5kHz mode the calling station are easy to see compared to fix 20kHz and +/-5kHz selections. But best of all I have fixed mode operation of VFO B with these small spans.

K7K expedition how did it work out for you?
It's Tuesday early morning and I am greeting my first cup of java along with some radio time. I found myself drifting off to the weekend of radio operating. I very much enjoyed the Islands on the air contest (IOTA). It was also my plan to get K7K from Kiska island in the log as well. As the saying goes "sometimes things do not work out as planned".
I was keeping an eye on the DX clusters to see when K7K was on air and where. This year is my "year of CW" so I was looking forward to getting them in the log using CW. Again sometimes things don't work out as planned. I noticed once K7K was up and running that FT8 seemed to be their mode of choice for most of the time. I was reading on the cluster posts there were some upset ops... that very little time was spent on SSB or CW.
I am not here to rag on FT8 and to be honest, I used this mode a great deal last year and very much enjoyed it. But having said that in my humble opinion they operated FT8 about 70-80 percent of the time and left modes such as SSB and CW alone.
In the expeditions, defence conditions for them could not have been great and the Digi mode FT8 would sure fill their logs up and better than a poor showing in the log book. Also maybe the tide is shifting and with the Dx Peditions to come FT8 and other Digi modes may be the choice of the operators.
I did notice K7K on their website indicated FT8 would be used but they also included CW and SSB.
There was an occasion CW and SSB were used but on a limited basis. I will chime in and say the only long period of time they used CW was in the IOTA contest. They are indeed an island and rare as well, it was expected for them to take part BUT this seemed to be the only time K7K used CW.
I checked the clusters during the contest to see where they were. I did notice comments of frustration, K7K was operating split and some contest ops were calling on K7K calling frequency. Other comments indicated stations calling CQ contests in the responding TX frequency. Then I found they went back to FT8 in a very short time during the contest.
This is just my humble blog opinion regarding the K7K "event" but when you indicate CW, SSB and FT8 on your site giving equal time to all would be a positive thing. From what I read in the cluster comments there were more than a few unhappy campers.
The up’s and downs of working DXpeditions.
Now you see them now, you don't.... the fun of active solar conditions |
Earlier this week and last week the solar conditions have been great, and I have been able to make some nice CW DXpedition contacts. The whole DXpedition thing is new to me, as in the past I have seen the pileups and just passed them by. With the increasing flux number and with the blog reading I have been doing, it occurred to me that the times are a changin! I did some reading up on my Icom 7610 and operating split with it. Low and behold, I have been able to make contact with some nice DXpeditions.
Being new to this expedition thing, I have in the past read of those who indulge in this slice of our hobby. I have now come to see firsthand the mayhem of a pileup situation. I don't want to make this post about grinding my axe.....BUT......and you know what they say about a sentence that begins with a "BUT". In my very very short time of hunting out a DXpedition contacts I have come across some odd....... Let's say behaviour.
1. As you are listening on the DXpeditions transmit frequency they vary between S4 to S8 at my end, and I am trying to get the flow of their operating........... When someone for some reason is tuning up their amp on top of the DXpedition? To be honest I have never owned an amplifier and am not sure how the whole tune-up thing works........BUT....... I assume it does not have to be done on the DX transmit frequency. Please correct me if I am wrong?
2. Ahh, then those who I guess who do not do their research with understand the idea of split frequency operation or don't care.......BUT..... they transmit on the DXpeditions frequency. So what happens here is stations like me can't hear who the DXpedition is coming back to as this station just keeps dropping their call on the WRONG frequency. Ok, I get it, and we all screw up thinking our rig is in split when it's not.....BUT..... with my limited time trying to work split this happens a lot. With polite op's from a DXpedition they send "up up up up" hoping the offending station will get the idea. Oh, but wait then there are the clusters such as DX summit and in the comment section, other ops are not so polite about things.
3. Often I have heard the DXpedition station sending "VE3?" meaning he wants the VE3 to come back to him as he needs the rest of the call. As they listen for the VE3 there are also a few op's sending their call that is not even close to "VE3". It really messes things up for both the VE3 station the DXpedition.
Now, there is some other behaviour that I come across that make DXpeditions a pleasure.
1. While the op is calling on the DXpeditions calling frequency they politely answer them with a 599 and TU.
2. Operators who, while sending out their call, can hear the DXpedition station answering someone other than them, and they stop calling right away. They can achieve this as they have their radio set to full break-in mode. This will allow you to hear between your own dits and dahs, I will admit it takes some getting used to, but it's a great operating skill.
3. Operators who politely post on the cluster the operators call sign and leave a message that they have to transmit up and not on the calling frequency. Having said that, I have also seen some messages that are not polite at all. I understand folks get frustrated, but there is no reason to be rude, after all it is a hobby.
Well, we are going away on vacation this week, so the DXpeditions will have to wait for another week. But I sure have been having fun working them.
