Another reason to be familiar with Morse Code: Lights and buoys - Aids to navigation
23. April 2010 by admin.
Besides the fact that some ham radio operators still enjoy CW, in other words Morse Code Communications, *it* is no longer a requirement for a U.S. Amateur Radio License at any level. That lets a lot more long time hams, and new potential hams, get licensed at the higher license class levels such as “General” and “Extra” class. Anyway back to marine stuff for my boating and yachting readers…
Some Buoys and other aids to navigation flash a light at a periodicity designed into them. Often this is sequence that lets them be recognized among other navigation aids in an area. Sometimes that sequence is a Morse Code letter. Now you don’t have to be able to read words at 20 words per minute or even 5 words per minute for marine navigation purposes, but it might be nice to at least be familiar with your Morse Code Alphabet, that way when a buoy that you see - is flashing a Morse Code letter you can recognize it and find that buoy or other navigation aid on your chart plotting software or hardware (or paper charts if you are using that.)
I just found this link, and there are no doubt others. I’m sure that I’m not telling most boat and yacht captains anything new, because this stuff was in your training for your license.
I will tell you that I did marine navigation in the U.S. Navy from 1977 to 1981 with at least 2 Mediterranean trips and some Caribbean and other East Coast U.S. sea time as well. Back then it was all paper charts (back when there were Wooden Ships and Iron Men… ha! ha! ha!) along with Loran C and such (which just shut down recently btw.)
http://www.sailingissues.com/navcourse9.html
Aids to navigation
Aids to navigation are special structures like lighthouses, lightships, beacons, buoys, etc that are used to enhance safety by providing more opportunities to obtain LOPs.
These lights and marks are prescribed across the world by the International Association of Lighthouse Authorities (IALA). In 1977 this IALA endorsed two maritime buoyage systems putting an end to the 30 odd systems existing at that time. Region A - IALA A covers all of Europe and most of the rest of the world, whereas region B - IALA B covers only the Americas, Japan, the Philippines and Korea. Fortunately, the differences between these two systems are few. The most striking difference is the direction of buoyage.
All marks within the IALA system are distinguished by:
Shape
Colour
Topmark
Light
Light identification
During daytime, the identification of aids to navigation is accomplished by observing: location, shape, colour scheme, auxiliary features (sound signals, RACON, RC, etc) or markings (name, number, etc).
During the night, we use the features of the aid to navigation’s light to both identify it and ascertain its purpose. There are three features to describe the light:
Colour: Either white, red, green or yellow. If no colour is stated in the chart, default is white.
Period: The time in seconds needed for one complete cycle of changes. The arrow indicates the 10 second period of this flashing light “Fl(3) 10s”.
Phase characteristic: The particular pattern of changes within one complete cycle (hence, within one period). Below are the most common types:
Fixed F
This light shines with an unblinking and steady intensity and is always on. In this example a yellow fixed light is shown.
Flashing Fl:
The duration of the light is always less than the duration of the darkness. The frequency does not exceed 30 times per minute.
Quick Flashing Q:
Again, the duration of quick flash is less than the darkness. The frequency is at least 60 times per minute.
Very Quick Flashing VQ:
Also here, the duration of very quick flash is less than the darkness. The frequency is at least 100 times per minute.
Interrupted Quick Flashing IQ:
Like Quick Flashing with one moment of darkness in one period.
Isophase Iso:
This Light has equal duration between light and darkness. A period consists of both a light and a dark interval. Also called Equal Interval (E Int).
Group Flashing Gp Fl(x+x):
This is actually a combination of two patterns in one period. In this example the first 2 flashes followed by the pattern of 3 flashes result in: Gp Fl(2+3).
Occulting Occ:
Occulting is the opposite of flashing, the light is more on then off.
Alternating AL:
An alternating light changes colour. This special purpose light is typically used for special applications requiring the exercise of great caution. In this example ALT.WG is shown, alternating between green and white.
Morse U Mo (U):
This light shows two flashes and a longflash, which is equivalent to the letter “U” in Morse code.
Long-Flashing LFl:
This light has one long flash in a period. A long flash is at least 2 seconds long.
Let’s look at some examples using colour, period and phase characteristics. The arrows mark the periods:
Fl (4) 8s
Oc (2+3) 10s
Iso G 4s
All lighted aids to navigation are either major or minor lights, where major lights are used for key navigational points along sea-coasts, channels and harbour and river entrances. These lights are normally placed in lightships, lighthouses and other permanently installed structures, providing both high intensity and high reliability of the lights. Major lights are then subdivided in primary lights (very strong, long range lights used for the purpose of making landfalls or coastal passages) and secondary lights (shorter range lights found for example at harbour and river entrances). Important details of (especially) primary lights can be found in a reference called the Light List where information (about pedestals etc.) can be found which is not included in the chart.
Minor lights on the other hand are likely to be found within harbours, along channels and rivers. These have a low to moderate intensity and sometimes mark isolated dangers.
(more at the link above)
* I will also relate that on some ocean or inland passages it is remotely possible to be challenged by a Morse Code Light Communications station - asking you who you are in Morse Code. Now that probably won’t happen to your average Sail or Motor Yacht … but it did happen to me one time onboard the U.S. Navy Ship: U.S.S. Recovery ARS-43. While negotiating - The Straits of Messina? I believe it was … of Sicily … we were confronted by a Signal Tower on our approach. Fortunately I was a Signalman by trade and was trained in communicating by Morse Code by Flashing Light. How about that?

IRAZU VOLCANO, Costa Rica - Tango India 2 November Alpha: TI2NA CW Beacon being spotted on 50.080 Mhz

Tango India 2 November Alpha: TI2NA CW Beacon being spotted on 50.080 Mhz
6M BEACON

IRAZU VOLCANO,
Costa Rica

TI5KD current maintainer of TI2NA CW Beacon on 6 Meters / 50 Mhz
—
Erik, TI2NA, now a silent key, was an amateur radio pioneer in Costa Rica and in Latinamerica. One of the first experimenters in the satellite modes and in many other VHF/UHF activities, he put in operation, the first Central America 6M radio beacon on 50.080, in the 1960’s. Homebrewing most of his equipment, he went through two different designs for the beacon which he kept and maintained on his family farm in Eastern San Jose.
Some years ago, a new bulletproof beacon was designed and built by George, W1XE and pressed into service soon after. Since Erik’s death, the beacon has been maintained by myself, Keko, TI5KD. I have relocated it to our 440 Group repeater site on the top of IRAZU volcano at 3432 meters (11,200ft) in grid EJ89bx. It transmits a CW message once every 20 seconds or so and puts out 30 W into a vertical dipole. Being in the best location it has ever been, it will be heard earlier than stations located in the Central Valley where we are surrounded by mountains.
Erik’s callsign has now been permanently assigned to the beacon through the Costa Rica Radio Club
If you hear the beacon, please report it on the internet clusters so others can be alerted of the opening.
Best 6M DX,
Keko, TI5KD
Video of reception on the TI2NA/B CW Beacon today, and my attempts at CW contact on a nearby frequency. Noone seems to be around either on CW or SSB from that area…
—
So far no 6 Meter contact has been landed by KA4UDX from these reports. There are, however, 4 reports of hearing the Morse Code, CW beacon, on or around 50.080 Mhz.

Yachts/Boats: Waterway Radio and Cruising Club - 7268Mhz Amateur Radio
21. April 2010 by admin.
Waterway Radio and Cruising Club - Emblem - Image
The WRCC - Waterway Radio and Cruising Club - on the air this morning since 07:45 Eastern Time, as every morning. A good place to check in if you have a General Class or higher Amateur Radio License (anyone can listen with an HF/SSB Radio). Position Reports taken and plotted, non-commercial traffic is often handled. Emergencies and Safety situations can be handled - and it’s a great group of people, from the Control Operators of the Net, The Fleet Captain(s), and the other Shore Stations (like myself) and Boats that check in.
This is a good place to warm up your SSB radio, even if it’s normally dormant or off these days. It’s a good place to practice using your SSB radio … you never know when one day you may have to use it. It would be good to be familiar with the radio gear and know how to operate it in case you ever need it! Smaller vessels - SSB radio may be the only, or one of a precious few communications methods that you have when you are out of range of everything else. HF - SSB radio never goes down. It might be good to be familiar with this net on 7.268 Mhz, and the other Maritime Service Net on 14.300 Mhz. If anyone needs further information on these nets - please do not hesitate to contact me via Email, etc.

Rain on the Scarecrow DX on the Antenna? 6 Meter Band Opening
21. April 2010 by admin.
Sporadic E Image from http://www.df5ai.net/Material/articles.html
John Cougar Mellencamp sings about “Rain on the Scarecrow Blood on the Plow” - tonight we will sing about rare long distance “DX” conditions on 6 Meters, a VHF band at 50 Mhz, normally with very short range and not useable for much. But tonight with rain coming down and some unique weather patterns through Florida and the Caribbean areas … It looks like what this has caused might be what they call “Sporadic-E” … a condition where the clouds or other parts of the lower atmosphere form a sort of temporary “Information SuperHighway” or at least a voice radio super highway for some short periods of time.
I’ve made 5 contacts with Puerto Rico, and one with the Dominican Republic. Here’s my log:
KP4EIT
HI3TEJ
KP4YI
WP4LUU
KP4BAI
NP3CW
Weather ConDX during 6m Sporadic E
Puerto Rico Contacts in Sporadic-E on 6-Meters
Dominican Republic Contacts in Sporadic-E on 6-Meters
Also of note, many of the stations in Puerto Rico, as I am doing also, are running only around 100 watts power - with not much in the way of fancy antennas. It was a very brave showing of Puerto Rican Radio Amateurs in this Band Opening.
I am running Hustler 6BTV Antenna (10, 15, 20, 30, 40, and 80 meter bands antenna). This antenna not even made to work on 6 Meters! But apparently it is working somewhat ok.
Video #1 - Puerto Rico Contact - KP4YI - His name is Ed
Video #2 - Puerto Rico Contact - KP4EIT - His name is Jose
Video #3 - Dominican Republic Contact - HI3TEJ - His name is TED
Note: I didn’t record and upload video of all 6 contacts, so this what I have other than my log.

Be Careful what you Tweet about you might just Get it!
20. April 2010 by admin.
Google to Index Your Embarrassing Twitter Trail
* The old saying “Be Careful what you Ask For - You just might Get it!” comes to mind. And a twist on that is … “Be Careful what you Publicly Communicate -as It just might Get You!” Everything is archived these days. You generally can’t expect to even have a poor web site in the beginning, and not expect someone to be able to go back and view what it used to look like. You can’t have a property (real estate) that used to look good, but has been left unimproved or a dead lot, because someone can go back and forward in time on Google Earth and see what happened (see my: Life After People Oakland Park, Florida article here on this blog.) So now Google will archive and make searchable your Tweets via the Twitter Service. And those tend to be somewhat like “text messages” on cell phones. You could bleep out something in the heat of passion that you’d want to take back afterwards. But you might no longer be able to. Future employers or others could look up what silly stuff, or damaging personal stuff, you may have tweeted … and use it against you - with or without your knowledge. — Alan Spicer
Google to Index Your Embarrassing Twitter Trail
Jared Newman
Apr 14, 2010 2:16 pm
Billions of Twitter posts will no longer fade into obscurity now that Google is indexing them all in a massive, searchable database.
Google announced a new search feature that lets users look at an entire history of tweets on any subject, in any time frame. The feature will roll out over the next couple of days, but you can see it in action now through a special link (ironically, it didn’t work for me in Chrome, but Firefox was fine).

So… back to Marine and Maritime… The Titanic was built just Northeast of the two Ham Radio DX Contacts in Northeastern Ireland
19. April 2010 by admin.
Good Monday Morning everyone…
Since this is a Marine Telecom Blog, back to Marine and Maritime… The Titanic was built just Northeast of the two Ham Radio DX Contacts in Northeastern Ireland:
http://www.onlinetitanicmuseum.com/unsinkable1.html
by Harland and Wolff - Queens Island, Belfast in Northern Ireland, somewhere abouts:
54°36′22.33″N by 5°54′15.29″W
which is around 20 miles northeast of my MI0SMK amateur radio contact, and 30 miles northeast of my MI0SAI amateur radio contact.
There - the Arrol Gantry was used to construct the Olympic-Class liners:
http://www.onlinetitanicmuseum.com/harlandcard2.html
* The Titanic sinking ushered in a lot of changes to Marine (Maritime) Communications and Safety Practices in the industry worldwide. From “CQ D” (CQ Distress) to the first use of the distress signal “S.O.S” in Morse Code … to the current day Satellite, Cellular, GPS, and WiFi used for communications and navigation.
So here we are -

2nd Luck of the Irish… MI0SMK
19. April 2010 by admin.
My 2nd Ireland contact occurred today. Actually I tried to work this one the other day when I worked the MI0SAI station but he was asking for West Coast US Stations only to call him. Today I found a spot, a time, when he just did a general “QRZ”. He remarked on good clear “DX Quality Audio” from my station (attributed to Heil Microphone HM-10 in “DX Dream Machine: Wide - mode.)
MI0SMK - Northern Ireland, Amateur Radio
Contact time 23:46 UTC - 14.256 Mhz. Some info from QRZ.Com:
| Latitude: | 54.478333 (54° 28′ 41” N) |
| Longitude: | -6.293333 (6° 17′ 35” W) |
| Grid Square: | IO64ul |
| Bearing: | 40.3° NE (from KA4UDX) |
| Distance: | 4125.9 mi (6640.0 km) |
Hi there, my name is Rich and I am 39 years young - thanks for looking me up and also for the QSO if we have worked recently.
Enjoying this great hobby immensely although family life and the “joys” of self-employment means play-time on the radio takes a poor 3rd place.
QTH is a small village approx 20 miles SW of Belfast - grid locator IO64UL.
Working conditions are simple & straight forward (like the operator lol) -
FOR HF: Yaesu FT1000MP MkV using Heil Proset Plus Headset.
FOR 6m/VHF: ICOM IC-7400 with SM-20 Microphone.
FOR PORTABLE: Yaesu FT-857D

Contact Made: EH1ARD (Spain) - Special Event Call Sign: World Amateur Radio Day 2010
19. April 2010 by admin.
* Lot’s of RF (Radio Frequency) energy in the air this weekend. Several contests going on, some ”QSO Party” contests and an ARRL Rookie Roundup which is for newly-licensed operators in North America: http://www.arrl.org/rookie-roundup. So maybe there’s enough Ham Radio “Radio Energy” in the air to knock the Volcano Ash out and let the planes fly. That’s right - Let The People Go! Let the planes Fly!!!!
On 20 meters, frequency 14.287 Mhz at 21:22 UTC time contact was made with EH1ARD

World Amateur Radio Day 2010
Each year on 18 April, radio amateurs celebrate World Amateur Radio Day. On that day in 1925 the International Amateur Radio Union (IARU) was founded. In 2010, the theme of the event is “Amateur Radio: Combining communication experience with modern digital techniques.”
Amateur radio has truly entered the 21st Century. In less than 100 years amateur radio communications has evolved from crude spark-gap technology to digital signal processing and software-defined radios. The amateur’s HF choice between voice and CW has been expanded to a broad range of communication choices from television to spread spectrum.
Amateur digital communications has evolved. At the end of World War II until the early 1980’s, radioteletype, also known as RTTY, was the only HF digital mode available to amateurs. In the 1980’s, AMTOR made its debut along with the increased popularity and availability of personal computers. AMTOR was the first amateur digital communication mode to offer error-free text transmission.
From the early 1980’s, the rate of change increased dramatically. Packet Radio emerged and for a period of time was the most popular form of amateur digital communication. As microprocessor technology became more sophisticated, there was a rise in modes such as Clover, PACTOR, and G-TOR that were capable of error-free exchanges under marginal band conditions. In the late 1990’s, there was an invention that harnessed personal computer technology to create PSK31.
In the VHF-UHF frequency ranges, Packet Radio had less activity at the close of the century than it did in the 1980’s and 1990’s. However, Packet Radio was reborn as the popular Automatic Packet Reporting System (APRS) and traditional packet systems still exist to support public service activities with greatly enhanced functionality.
Thanks to individual amateurs, hams now enjoy digital meteor scatter contacts and even moonbounce on VHF and UHF frequencies with modest stations. An ordinary computer sound device and software that can be downloaded free from the internet is all that is needed.
The Japan Amateur Radio League developed the D-STAR digital voice and data standard and there has been significant amateur growth as amateurs establish D-STAR repeater networks on the VHF, UHF and microwave bands.
All of these development have inspired amateurs around the world to experiment in their own HF, VHF, UHF and microwave band digital communication.
Activities on the occasion of World Amateur Radio Day 2010 can be a great opportunity to spread the word about what the “hams” are doing in the 21st Century
DIA INTERNACIONAL DEL RADIOAFICIONADO 2010
El 18 de abril de cada año, los radioaficionados celebran el Día Mundial del Radioaficionado. Fue el día en que se fundó la International Amateur Radio Union (IARU) en el año 1925. En 2010, el lema del evento es: “Radioafición: combinando la experiencia de las comunicaciones con las técnicas digitales modernas”.
La radioafición ha entrado de verdad en el siglo XXI. En menos de 100 años las comunicaciones de radioaficionado han evolucionado desde la primitiva tecnología de chispas hasta el procesamiento digital de señal y las radios con software. La clásica elección entre fonía y telegrafía en HF se ha ampliado con más opciones.
Las comunicaciones digitales de aficionado han evolucionado. Desde finales de la Segunda Guerra Mundial hasta principios de los años 80, el radioteletipo, también llamado RTTY, fue el único modo digital de HF al alcance de los radioaficionados. En la década de los 80, el AMTOR hizo su debut, que incrementó su popularidad al extenderse el uso de ordenadores personales. El AMTOR fue el primer modo de comunicación digital de radioaficionados que ofrecía una transmisión de texto libre de errores.
Desde principios de los 80, el cambio se empezó a notar cada vez más. Surgió el radiopaquete y durante un tiempo fue el medio de comunicación digital más popular. A medida que la tecnología de los microprocesadores se hacía más sofisticada, surgían otros modos de comunicación como el Clover, PACTOR y G-TOR, capaces de transmitir sin errores bajo mínimas condiciones de banda. A finales de los 90, aprovechando la tecnología de los ordenadores personales, se inventó el PSK31.
En las bandas de VHF-UHF, al iniciarse el siglo XXI había menos actividad en radiopaquete que en las dos décadas precedentes (años 80 y 90), pero renació con el APRS y los sistemas tradicionales del radiopaquete aún existen como apoyo a actividades de servicio público con su funcionalidad mejorada.
Gracias al esfuerzo de algunos, los radioaficionados disfrutan ahora de contactos digitales en los modos de dispersión meteórica y rebote lunar en frecuencias de VHF y UHF con estaciones modestas.
La Japan Amateur Radio League (JARL) desarrolló el sistema digital de voz y datos D-STAR, con un crecimiento significativo cuando los radioaficionados establecen redes de repetidores D-STAR en las bandas de VHF, UHF y microondas.
Todos estos desarrollos han inspirado a los radioaficionados de todo mundo a experimentar por sí mismos en las comunicaciones digitales en las bandas de HF, VHF, UHF y microondas.
Las actividades que se realicen con motivo del “Día Mundial del Radioaficionados” pueden ser una gran oportunidad para dar a conocer al mundo lo que están haciendo los radioaficionados en el siglo XXI.

What Time Is It? Coordinated Universal Time
17. April 2010 by admin.
I have no doubt that most yacht captains, first mates, and others are aware that time is kept, worldwide in a 24 hour format. Honestly I like it better that way. Maybe that is the military in me, or has something to do with ham radio, or both.
Most persons probably get their time these days from a cellular telephone network, or via GPS Satellites on gear that supports that. And these are no doubt derived from “something” right?
Anyway there are time zones in the U.S. (yah I happen to be there) and worldwide. So how do you set your watch? I mean to be accurate? Well that depends on how accurate you want to be. All time pieces will have some “drift” and will gain or lose time.
In the US Navy - many a time - I took a WWV “time tick” so that the Executive Officer could shoot stars (Celestial Navigation) which required exact time of recorded sightings.
Anyway …
http://en.wikipedia.org/wiki/WWV_(radio_station)
Is one older time standard broadcast of such time synchronization … probably still used by some. I think my Casio watch, which synchronizes, not by GPS, does that. And it seems to be in perfect step with what I am hearing on 5Mhz tonight … and 10 Mhz as well.
So if you get LOST … you could find the time by tuning to one of those frequencies.
It’s also, I believe, a frequency standard … and I tried on LSB or USB and you can “zero beat” the WWV signal and get a pretty good idea that your receiver is indicating correctly for that particular frequency.
So here is THE TIME MACHINE signing out,
