CY0C, Sable Is. .. se podría CANCELAR

La operación que se tiene que llevar a cabo el día 8 de setiembre se SUSPENDERÄ, si las condiciones de la arena en la isla continúan como actualmente,  en la web se informa:

01 de septiembre 2014 (Boletín )

Aaron Carpenter, Coordinador de Operaciones de Parks Canada, Sable Is, ha asesorado al equipo CY0C que SUSPENDAN el vuelo hacia la isla Sable. Esta suspensión se debe a las condiciones anormalmente secas en la Isla y la imposibilidad de asegurar que los aviones de Britten Norman Islander puedan aterrizar sobre la arena seca y suelta. 

La reciente tormenta / huracán Cristóbal inundó partes de la playa, que han hecho que la arena no esté firme para el aterrizaje al secarse. Esto y la lluvia que se pronostica para el lunes, 1 de septiembre, no ayudaría mucho a tomar tierra. Parks Canada mantendrá actualizado al equipo de CY0C durante la semana. 

Parks Canada confirmó que hay dos días disponibles para que el equipo pueda acceder a la isla. La fecha principal es el lunes, 8 de septiembre con una fecha alternativa del martes, 9 de septiembre Si los vuelos no son posibles en esas dos fechas, la DXpeditión tendrá que ser CANCELADA. Debido a los requisitos operacionales, Parks Canada informó que no habrá otras aperturas al público para este año. El equipo CY0C tendrá que dejar pasar la semana ansiosos esperando buenas noticias, sobre las condiciones de aterrizaje en la isla. Por favor visita la web para estar bien informado con las últimas actualizaciones. 

Gracias y 73,

20m activity

I called CQ on 20m in JT9-1 and then JT65 just before tea without success. Since switching to 20m WSPR I was met with immediate success.  VK5MR was copied and now there are plenty of Canadian and USA stations being spotted or spotting me.  WSPR really is a good mode.

UPDATE 1856z:  OX3XR (3206km) was a new country on 20m WSPR just now. 12 reports received in a single WSPR 2 minute transmission!

Some radio but a lot of photograpy!

On Friday (since I had the day off) I felt it was about time to take the Elecraft KX3 and do some portable op's since the weather did not seem like it was going to co-operate once again I operated from the car. I used my mobile whip antennas again and if you remember from my last post I had an error message show up on my radio ERR TXG! Well I tested all the mobile coax and mount  all seemed fine. I did clean the antenna mount connections and this time out all seemed to be well with no error messages. I had about an hour and a half of radio time. I found 20m to be dead with little or no activity I ended staying on 30m but was skunked with regard to contacts. The propagation gods were just not smiling on me this time. The rest of the weekend Julie and I took in the Canadian International air show. On Saturday we were off to Toronto Island it's a short ferry ride into Lake Ontario and in the past this was a great place to get pictures of the air show. This time around it was a good day to sit on the beach and relax with only a few good shots! The Toronto Island for sure was not a good place for photographing the air show as many other would be shutter bugs found out as well. It seems the flight pattern had changed and as Julie pointed out looks like they are flying right over our condo which also is on the lake. On Sunday we went up to the roof top patio on our condo and waited to see what kind of shots we could get. below are the results the cameras used are the Nikon D810 with Nikkor 70-200mm F2.8 glass with a Nikon 2x tele converter I was using the Nikon D800 with Sigma 50-500mm F4.5 glass. The RAF SE5 was about 2 KM's away from us. The C-123 was buzzing a condo that is about 1/2 KM away from us. So not much ham radioing this weekend but I do have Tuesday off as well and you never know I could have the radio god's smiling on me!

More original K2DSL – 1950′s QSLs

Back in 2009 I wrote a post and was in contact with Merceda aka “Bunny” the original holder of K2DSL in the 1950s.  After a contest a few weeks ago where K2DSW (Bob now in Iowa) and I, K2DSL were often following each other making contacts, I sent Bob an email, In our exchange he asked me about the original K2DSL as he had made contact with her and sent me some QSL cards from his exchanges.  With Bob’s permission, I’m posting the QSL cards from his contacts with the original K2DSL back in the 1950s when Merceda was between the ages of 13 and 15 years old.

1954 – Age 13 (click images to enlarge):

Bob also sent along a scanned copy of a reprint from a CQ Magazine article on Young YLs. I’ve included the snippet on K2DSL which includes a picture of Merceda (aka “Bunny”). Again, click for a larger more readable view:

I’ll have to check in with Bob and see if he was able to get in contact with Merceda using the email address I had from 2009. Interesting look back into the past. Thanks again Bob for the great scans on those cards from the 50s.

10m - still good Es and GDX , but no F2 seen here yet

PT2WWV stopped coming through late last evening but this morning Es has been good from southern Europe since before breakfast. Overnight  a couple of new G stations were seen G3ZTU (144km) and G7EOB (76km).

Sunspot count today is 90 and 20-30MHz propagation "fair". F2? Any ones guess.

UPDATE 1507z: Spanish stations have been coming in by 10m Es all day. So far,no F2 propagation has been seen here,

UPDATE 1525z:  QSYing to 20m for some JT9-1 2-way QSOs I hope,

Craig / 29 agosto 2014

Es sábado por la tarde he aterrizado a salvo en Darwin para reunirme de nuevo con mi esposa. La madre de mi mujer tenía un propósito importante, que era estar en compañía de mi esposa en Darwin mientras yo estaba jugando a la radio en la isla. Es sólo una cuestión ahora de ver la cantidad de dinero que han gastado en compras en Darwin, mientras yo he estado en la isla durante 4 días.

Estoy absolutamente exhausto después de operar ayer sin parar desde las 06:00-17:30 UTC (15:30-3:00 am, hora local) y luego empaquetar rápidamente para irme al barco por la mañana y llegar a tierra, siempre y cuando los vuelos cumplieran con los horarios.

Afortunadamente estamos en vacaciones todavía durante un par de semanas más. Volamos a Broome en Australia Occidental mañana por la mañana por lo que voy a publicar la historia en el blog con fotos de esta DXpedition en los próximos días mientras esté de vacaciones con la familia. Luego volaré a Adelaide para participar en la gran operación VK6ISL OC-294.

Hoy he subido los QSO a ClubLog, para  que la gente pueda comprobar que están ahí o hacer sus peticiones OQRS.  

Yo también he enviado mi foto a UX5UO para que pueda comenzar a imprimir las Qsl de VK5CE /.

Si tienes alguna pregunta o si no te encuentras en el log online, pero consideras que tu Qso tendría que estar, envíame un correo electrónico a vk5ce@yahoo.com.au . Voy a empezar a revisar todos los correos electrónicos la próxima semana.

Vuelve dentro de la próxima semana para ver la historia y fotos, 73s de Craig VK5CE

Die Bedeutung der Taktung

Oft scheint es hauptsächlich interessant, wie es mit dem Minutenpreis aussieht, der bei einem Handyvertrag festgelegt wird. Trotzdem liegt es auch an den Details, wie zum Beispiel an der Abrechnung selbst, wenn es darum geht, günstige oder teure Angebote wahrzunehmen. Deshalb ist es umso wichtiger, sich zu informieren, wie es mit der Taktung an sich aussieht, die im Vertrag angegeben wird, wie zum Beispiel 60/10 oder anders.

Taktung 60/10

Die Taktung 60/10 bedeutet für den Handy Nutzer, dass es sich um einen speziellen Handyvertrag handelt. Das bedeutet, dass ganz besondere Vereinbarungen zum Zuge kommen, auf die zu achten ist, wenn Wert auf einen guten Preis für die Sprechzeit gelegt wird. Umso wichtiger ist es, sich selbst mit dem Gesprächsverhalten zu analysieren, um die passende Taktung dazu herauszufinden. Dadurch wird nämlich der grundlegende Vertrag mit dem gesamten Preis in seiner Basis bestimmt. Weitere Infos zur Taktung gibt es hier: http://www.handy-flatrate-24.de/informationen/taktung.php

Definition der Angaben

Es funktioniert gut, sich als Beispiel eine von 60/10 vor Augen zu halten. Das Ziel ist es, zu ergründen, was eine solche Angabe überhaupt bedeutet. Die erste Zeit, nämlich in diesem Fall die 60 bedeutet, dass der volle Minutenpreis auch dann verrechnet wird, wenn das Gespräch bereits nach wenigen Sekunden schon wieder beendet wird. Eine genaue Berechnung der tatsächlichen Sprechzeit wird nur dann vorgenommen, wenn die zweite Minute im Gespräch beginnt. Dann geraten folglich sechs Abschnitte mit einem jeweiligen 10 Sekunden Takt in der Aufteilung für die Abrechnung in den Vordergrund.

Der passende Handyvertrag

Die Taktung ist tatsächlich ausschlaggebend und die Basis für die Abrechnung. Das heißt das nichts anderes, als dass der Minutenpreis 60 Cent beträgt. Diese Berechnung wird auch dann herangezogen, wenn das Gespräch, wie bereits erwähnt, nur wenige Sekunden dauert. Dauert das Gespräch länger, kommen die 10 Sekunden zum jeweiligen Takt für die Abrechnung infrage. Es werden also im 10 Sekunden Takt zehn Cent verrechnet. Mit dieser Erklärung der Taktung kann jeder sein eigenes Nutzerverhalten anpassen, wenn ein Tarif ausgewählt werden sollte. Neben dem Minutenpreis ist aber auch noch die Wahl des passenden Handyvertrages ein wichtiges Kriterium, das unbedingt im Vordergrund stehen sollte.

Sunspots and 10m

Sunspot count today is 64 (modest) and 20-30MHz propagation "normal". 10m F2 is possible. Es and GDX are still quite likely, although so far on 10m WSPR it has been quiet with just local G4KPX (14km) spotted strongly at -7dB S/N.

There are a couple of signals coming through for much less than 2 minutes that may be Es or even MS. So far, these have not decoded.

G0LRD (25km) has spotted me now at -13dB S/N.

UPDATE 1538z:   PT2WWV (8873km) has been spotted by F2 this afternoon. Earlier in the afternoon,there was Es from Spain.

UPDATE 1835z: Italians now being spotted by 10m Es - IK1WVQ (1084km) and IK3NLK (1136km).

UPDATE 1900z: PT2WWV (8873km) is again being spotted. Not sure if this pure F2 or a combination of F2 and Es. So far, the Brazilian has been spotted 5 times.
UPDATE 2025z:  PT2WWV has been spotted 11 times so far today.

UPDATE 2200z: PT2WWV  has been spotted 19 times on 10m WSPR today so far. I shall leave WSPR running overnight to see when this F2 opening finally ends. 8873km is a decent distance on 10m this long into the evening and darkness here.

Selling a Slice of Paradise Pie in Costa Rica

Though our son's college days are still at least a couple of years away, my XYL and I decided it's a good time to add to the lad's college fund and free up some more time for other projects, so we are dividing our farm and selling pieces or the whole shebang if someone comes up with our price. We wouldn't be leaving Costa Rica in any case, however.

There's no need for me to go into the gory details here as it's all laid out on my other blog, in this post about our sale and on this fixed page that gives more details about each lot.

Special deal for hams who want to buy the house: I'll throw in my rigs and antennas at no extra charge! That would be a couple of full K2s, Ten Tec Argo V, 500W amp, lots of tuners, etc. and five antennas already up.

2014 SCC RTTY Summary & Stats

Now that I posted about the SARTG & NAQP contests from a couple weekends ago, I can get to this weekends summary.  Starting Saturday morning on the East Coast is the 24 hour SCC RTTY contest that last for 24 hours. The exchange to send between stations is the year the operator was first licensed so I send 2007. Each unique year on each band counts as a multiplier for your final score.

I decided to use the N1MM+ beta version that was released. Though it has been available for anyone to use for 2 weeks, last weekend I wasn’t home so this is the first weekend I could use it in an actual contest. For the most part it worked fantastic which just a glitch near the start where I was replicating an issue someone else had and caused my installation to become corrupt, but it wasn’t difficult to recover. Anything else I ran into wasn’t critical and never prevented me from making a QSO and logging the contact. The N1MM+ development team has put in a tremendous amount of time and they are positioned to have an updated environment to build upon for many years.

Conditions were pretty crummy for me, especially early on at 8am local time and the activity was pretty slow at times so I did other things (aka errands) while I went back and forth to the radio.  The advantage of it being somewhat slow was I could mess around with N1MM+ and especially some of the new features/options to see how they worked. On Sunday morning, though I woke up before the end of the contest, conditions weren’t much better and I didn’t locate anyone on 40m or 80m so I worked a handful of stations on 20m before the contest ended.

Looking at the license data that is sent as part of the exchange, the earliest license date I received from another op was 1946 (born 1928 based on his QRZ page)  which makes the operator licensed for 68 years now!  I didn’t log anyone licensed in 2014 and just 1 operator licensed in 2013. The median license year I logged across unique operators was 1979 and the most frequent wasn’t much different with 1978 being the year the most operators I worked were licensed.

Here’s my N1MM+ score summary results showing the 216 Qs made in the contest:

 Band QSOs  Pts Year (mult)
  3.5   16   32   14
    7   64  129   39
   14  124  340   52
   21   12   33   10
Total  216  534  115
Score : 61,410

 

As you can see, most activity was on 20m for me until the evening. I was hoping for more US stations to be on to work 40m and 80m but they must have been doing other things on a Saturday night of a holiday weekend. No 10m activity that I could find and nothing very exotic.

 

Here’s a screenshot of the contacts made using ADIF2Map (click to enlarge):

Now time to unplug the antennas as a series of thunderstorms are about to pass through.

2014 SARTG & NAQP SSB Recap

As I was going to post about this weekend’s SCC RTTY contest I realized I hadn’t posted about the last contests I participated in which is now 2 weekends ago.  Well, here goes what happened back during the weekend of  Aug 16th & 17th…

Earlier in the week I brought my older daughter down to Clemson in SC to start her 3rd year there and now it was time to move my younger daughter into her NYC apartment before she gets started on her 2nd year at LIM College. So there really wasn’t a lot of time to get on the air but I managed to squeeze in some contacts in both the SARTG RTTY contest and the NAQP SSB contest.

In the SARTG contest I caught a little bit of the 1st of the 3 sessions over the course of the weekend. Missed all of the 2nd session. On Sunday morning 20m was active for the 3rd SARTG session. Happened to hear 2 loud JA stations while pointing to EU and worked them both before I spotted them on the cluster. Worked a bunch of JAs on 20m. 15 m was open at 8am ET / 1200z. I ended up working more JA mults then Canadian mults in the contest. With 135 Qs in the SARTG my wife and I headed back into NYC on Sunday to finish up getting her straightened out in her apartment.

N1MM score summary for the SARTG RTTY contest:

 Band QSOs Pts  Area DXCC
  3.5    4   35   1     4
    7   16  170   4     8
   14   81 1080  30    18
   21   34  470  23     4
Total  135 1755  58    34
Score : 161,460

The NAQP SSB was also that weekend with most of the activity taking place during the day or early evening on Saturday while I was in my daughters apartment putting Ikea furniture together until my fingers were bleeding!  When we got home late in the day I sat in the chair and worked as much as I could before I just needed to get some sleep. You can tell from the summary below that I was on 40m & 80m mostly vs any daytime activity that would have occurred more on 20m and 15m . But I made some contacts and can’t complain at all.

N1MM score summary for the NAQP SSB contest:

 Band QSOs Sec DX
  3.5   21  11  0
    7   69  26  0
   14   37  13  1
Total  127  50  1
Score : 6,477

Not bad with 262 contacts made in a weekend I didn’t think I’d even be able to turn on the radio. Daughter moved in, QSOs made, logs sent to all services/sponsors, and I’m a happy fellow! Apologies again for the late post.

Dangerous Skies l Old Man And An Old Dog Pt. iii

He called off the pod of drones after hunting his prey and communicated to his superiors headquartered on Heard Island. Their attack succeeded in stopping Launch Corporis of LAX for the moment and the Osprey was damaged beyond repair. It left them enough time to coordinate their next strike.

The lanky young man with fingers like those of spider legs pushed himself away from the console. He walked up the staircase leading out of the basement and into the meat locker air. The cold felt warm to his skin and he lit a cigarette in celebration.

Meanwhile.

Easter Island
Maxim fought against the control stick while his aircraft bled hydraulic fluid from the wound inflicted by an air-to-air missile. The pod of lethally armed drones surprised him and Maxim wondered why his radar didn't detect their signature? Stealth?

His Osprey tumbled like a rock and between the struggle for control when adrenaline inundates the brain, Maxim thought about the men he served with, in the mountains of Afghanistan.

Maxim pressed the push-to-talk button, "Jacqueline! Buckle up."

He pushed the throttle forward demanding the last gasp of mechanical life from his friend then actuated the vertical take off lever downward. Stainless steel screws in both wings struggled against horizontally induced thrust.

He waited a split second and recycled the lever. Jacqueline squawked the intercom, "What the frack!"

Maxim slammed the vertical takeoff lever and the last ounces of hydraulic fluid surged toward the wing motors and stainless steel screws. The pair of Liberty engines started rotating toward vertical.

He looked at his altimeter. Five thousand feet until impact and oblivion. Maxim turned the switch on his communication console from very high frequency to high frequency and dialed 14333 megahertz, "Latitude 27.116 degrees south, longitude 109.3667 degrees west."

Jacqueline gripped her harness squeezing tight enough to drain blood from her hands. She thought about her parents and that Sunday afternoon when the devil reached out of the black sky. She remembered a sense of calm in her father's eyes when a fist of wind tore him away.

She swore at the maelstrom as a young girl and vowed revenge. Her single mindedness lead her into a career as a climatologist eventually landing her a position at Launch Corporis of LAX.

The Osprey's giant propellers rotated vertical and started auto rotating. At least, Maxim thought, the fuselage would absorb most of the impact avoiding the use of ejection seats. He didn't want a splash down in the Pacific Ocean and waiting below was an abandoned National Aeronautics and Space Administration shuttle landing strip.

The Lie
Bill did not buy the lie sitting next to him and Guthrie although he gave her a passing grade for guts. He looked over at Betty Sue who was staring out the window, "How old is your boy?"

She looked at him with bitter sad eyes like a woman who lost everything in her life except for the most precious of all, "He's a year old."

Bill sensed she did not want to talk and turned his attention to the gravel road in front of him. He thought about that long lonely stretch of life without anybody else except for Guthrie. Now, a strange twist in destiny, seated him with a woman and a baby.

Crazy times Bill thought to himself.

They warned us about the climate but who really cared? Their foreshadowed change never really mattered to him. He'd wake in the morning and the weather was predictable, routine, boring. Storms? Bill and Guthrie rode storms, many storms even one blizzard that turned Rapid City into a moonscape of snow. But, a storm that leveled cities? That surprised him and his old man bones.

Bill laughed. And, laughed again. His gesture was a shock absorber against the reality of complete devastation and loss.

Betty Sue shot him a glance then tucked the blanket around Joshua.

Bill said, "Don't you worry little lady. I know someone who can help us. I just hope we have enough gas to get too the Badlands."

To be continued...

73 magazine online

Just received this from Martin Mann in Cambridge. For some years Martin ran Cambridge Kits although I think he is now retired. When looking for a particular edition of 73, be sure to replace the year and month with the one you need. The year has to be changed in two places in the link!
"Roger, 
Have you heard of Bill Hoisington, K1CLL, now sadly a silent key?  He was a prolific contributor on UHF to 73 Magazine in the '60s and 70s and is still a good read today, at least for a dabbler like me.  No expensive ICs, ha.  There is a list of his articles at http://mikeyancey.com/73mag/listauthor.php?Author=K1CLL and you can download complete copies of each issue of 73 Magazine as at http://library.vss.pl/lib/mag73/1967/73%20Magazine%20-%201967-07.pdf .  The files are about 30MB and take about 5 min to download, the 73 server being rather slow.  For something a bit meatier the HICKMAN, I. (2002). Practical Radio-Frequency Handbook (3rd ed.) at http://worldtracker.org/media/library/Electronics%20and%20Communications/Electronics%20ebook%20collection%20II/HICKMAN,%20I.%20(2002).%20Practical%20Radio-Frequency%20Handbook%20(3rd%20ed.).pdfis pretty good and only 2 MB.  Do you know any other magazines with back issues on pdf ?  Hoping talking is easier for you now,

Crystal Radio with speaker output

This version of my Simple Crystal Radio has only 4 parts - a moulded inductor, a germanium transistor, an output transformer and a speaker.


Extensive trials indicated that transformer efficiency, rather than exact turns ratio, is the key to better performance. Larger output transformers outdid the smaller ones. Focus then shifted to power transformers as their inherently thick conductors render them most efficient for this application.

Successive trials with transformers rated 230V/12V-2A,  230V/24V-5A and 230V/24V-15A gave progressively better results leading to fair reception of the local 612kHz, 200kW AM broadcast station.

A 3Ω speaker gave the highest output.

Antenna is a 60' random wire.

472kHz WSPR overnight

Overnight, I ran 472kHz WSPR but only the same old stations spotting and being spotted.  After G3XDV last night, no new stations in the log. Even with 5mW ERP, I don't think I am missing much: this seems enough to reach most stations.

Have now QSYed to 10m WSPR.

Navassa está clasificado como el país #1 de la lista de los más buscados en ClubLog, ahora sabemos que se pondrá en el aire en los próximos 18 meses. Por lo general lleva 1 año planificar una Dxpedition y al tener que valorar la USFWS la elección del grupo que la llevará a acabo hablamos de febrero de 2016.

Cuando visité la web de K5D, ví que el grupo KP1-5 había ganado la solicitud y el permiso para operar desde Desecheo y lo activaron en febrero.

Sólo puedo imaginar que la activación de una isla del Caribe sería mejor en cuanto al clima después de la temporada de huracanes que termina en noviembre. Esto significa que será con toda probabilidad entre diciembre y marzo.

Voy a suponer que KP1 se active entre diciembre 2015 y febrero 2016, sucederá al mismo tiempo que Heard Is VK0EK y quién sabe tal vez otras 10 entidades del DXCC, más que interesantes, E3 y otras me vienen a la mente. En cualquier caso apuesto que a finales de 2015 y principios de 2016 habrá emocionantes operaciones TOP 10 del DXCC. Quién lo iba a decir, tal vez pueda sumar 3 0 4 nuevos países a mi Honor Roll#1 hasta 2016, sería toda una sorpresa, esperaba que esto me llevaría mucho más tiempo.

La propagación desde Heard será lo suficientemente buena en 40, 30, 20 y 17mts, siendo las bandas con la probabilidad más alta para la Costa Oeste.

En lo que se refiere a KP1 esto es lo que predice el servicio de propagación de K6TU, usando como archivo mi sistema de antenas.


Quiere decir esto que mientras Europa tendrá mayores posibilidades con FT4TA, NA las tendrá con KP1. Habrá una banda siempre abierta las 24 horas del día para el toral de los EEUU y un montón de horas en los que se varán favorecidos NA y SA. Para la Costa Oeste no hay un tiempo o banda donde se vea favorecida, yo esperaré a que la Costa Este y el Centro de los EEUU hayan dominado los pile up, entonces los del Oeste tendremos nuestra oportunidad.

Para mis 3 elementos yagi / 20mts la cosa estará así:



Todas las otras bandas tendrán más o menos el mismo patrón, puedo evitar las colinas en esa dirección, que están a 100º. No tendré oportunidad por los polos, pero no me preocupa la competencia con Europa, basicamente será una operación parecida a K5D y HK0NA.

Va a ser una operación emocionante y divertida.

VU4KV qrv on 6 meters in November



 
There will be a new dxpedition to Andaman (AS-001) and Nicobar (AS-033) in the month of November, 2014. The team is largely the same which was at VU7AG (Lakshadweep Islands 2013), with the addition of new members. The exact dates will be published once the logistics are in place. The call will be VU4KV.

Initially, a short duration activity will be carried out from Campbell Bay in Great Nicobar by few of the team members. This will be followed by a larger activation from Neil Island in the Andamans for at least 10 days.

As published in their web, they will have 6 meters with 500 w and a 5 elements yagi when at Andamans.
