QSL cards

One of the pleasant moments accompanying amateur radio activities comes when we receive so-called QSL cards that verify radio contacts with the counterparts. A package of cards arrived to my home from the card exchange bureau of the Japan Amateur Radio League last week.

Though there is no rare "DX" card in it, there are some interesting or colorful cards from foreign countries.


K7DJO. This was one of the three North American stations that called me on November 5, 2011, when I operated from Cape Futtsu, Chiba, in Minamiboso Quasi-National Park, World Flora Fauna number JAFF-048. I am pleased to find the following comment of John, the operator, on the reverse side:

"Thank you for the DX QSO. I enjoyed seeing the photograph posted on 73"

I know from the card that this station was a modest one with a rig of 100 watt out and a vertical antenna. I was running 50 watts and using a loop antenna.




I worked these stations on October 13, 2011, from Suga Island, Toba City, Mie, in the Ise-Shima National Park area, WFF JAFF-012. As the distance from the Suga Shima Lighthouse to the inn I stayed and set my rig is less than 1,000 meters, the operation was also good as an activation of the Amateur Radio Lighthouse Society number JPN-596.

The five watt output (QRP) CW signal of Fred, HB9DAX, was not so difficult to copy, making the contact a memorable one for me.

Test QRV on 6m Phone

In order to confirm that my new tranceiver works well when using phone mode, I set up a temporary dipole antenna for six meter band this afternoon.


By checking into an weekly on-air meeting of the local radio club in the evening, I was able to know that it worked all right. I operate by CW, radio telegrafh mode, most of the time, but as my new tranceiver is operational on 50MHz band, I am planning to set up an antenna for that band and to join in the on-air meeting regularly by phone mode.

New Tranceiver

I started to use my new tranceiver, Yaesu FT-450DM, 50 watt output, this afternoon.

The application of permit of the replacement of my tranceiver from Yaesu FT-757GX to the new one was filed on-line on April 6, using the site shown below.


As there had been no response since the transmission of the application, I called the authority and found out it would take two weeks more until my application would be processed. However, the official told me that it was all right to go ahead using the new rig as long as I reported the replacement, because it was within the specification of my license document.

By the way, the automatic antenna tuner, FC-1000, which I refered to under the title of "Gambling?" is working okey. The standing wave ratios are a bit high (1.4, 1.5) on some bands. I do not know why, but I can use the other automatic tuner built in the tranceiver for the time being.

Radio Club Meeting

A monthly meeting of the local amateur radio club was held yesterday, and I attended it.

Thirteen people were there including an observer who passed an examination of the third class license recently and was planning to come back to the hobby.

Being near the center of a big metropolitan area, most members of the club have difficulty putting up big antennas at their homes and are not so active on the air. The average age is as high as, or higher than the entire population in this field.

Two real senior members showed up yesterday. One has a call with two letter suffix. Another told us that he first applied for a permit in 1939, but was denied due to security reasons at the time. He somehow went on the air even during WWII, and heard some U.S. stations were on the air in spite of prohibition. He became an engineer at a broadcasting station later. One day, he bumped into a colleague who had a "QST" magazine in his pocket. By the suggestion of this colleague, the senior club member got his present license. We had another senior member, who used to have two letter "J2" prefix before WWII, but he closed his station due to health reasons to our regret.

Lighthouse Forum

Attended the ninth lighthouse forum held at Enoshima, Fujisawa City, Kanagawa, yesterday afternoon. It was my first attendence to the event. I had been aware of this event for the last few years, but had not been able to attend.

There were four presentations:

"The damages on the aids of navigation by the Eastern Japan Big Earthquake of last year and their restoration"

"An experiance of tsunami and afterwards" by a lighthouse enthusiast

"Lighthouse papercraft"

"Cape Roca and Portugal in the Age of  Great Navigation"

The presentations were interesting and informative for me. By the way, "the Age of  Great Navigation" in the title of the fourth presentation is my direct translation from Japanese. The term is used in Japan instead of "the Age of Discovery," because "discovery" does not make sence among us or in other countries that were discovered by the Portuguese and the other Europeans.

There is a small shop of lighthouse-related goods at Katase, the neighborhood at the opposite coast of Enoshima (Eno Island,) and it has been my rule to buy a lighthouse calendar for the last few years at the shop. The event was mainly organized by the owner of the shop.

Katsuura Lighthouse

The Katsuura Lighthouse was lit in 1917 for the first time. The height of the focal plane is 71m and one of the highest in the Kanto Region. I think that it is one of the most scenic in the region, though it takes time to approach.

Other specifications:

Height of tower: 21m

Range: 22 miles

Effective direction: 229 degrees to 73 degrees



The photo above is shot from Kangunzuka, which is about 700m to northeast.

Katsuura, Chiba

Went to Katsuura City, Chiba to operate amateur radio in the Minamiboso Quasi-National Park (WFF JAFF-048) and in the vicinity of the Katuura Lighthouse (ARLHS JPN-245) last Sunday and Monday. "Minami" means south, "Bo" is the short form of Awa, the name of an old province and "So" is also the short form of another old province Fusa. "Fusa" was divided into two provinces of Kazusa (Kadusa, Kamitsu-fusa) and Shimousa (Shimotsu-fusa.) Katsuura belonged to the former.


The lighthouse viewed from the Cape Hachiman.

I parked my car on the western side of the cape, about 500m from the lighthouse Sunday afternoon local time. The cove of Katsuura was in front of me.

I went to a parking lot near a monument to commemorate the soldiers who lost their lives due to a shipwreck on their way to Hakodate, Hokkaido in the civil war of 1868 Monday morning local time. This place faces northeast and about 700m from the lighthouse. The small sign reads "Keep clean in the natural park area."

Jotomyodai 常燈明台

There is a tower that resembles a lighthouse in front of the Tayasu Gate. It is called "Jotomyodai," meaning a tower of a ceaseless light. It was built in 1871 for the Tokyo Shokonsha Shrine, the forerunner of the Yasukuni Shrine, but as the light was visible from the Tokyo Bay and the Sumida River in those days, it is said to have served as an aid of navigation. The tower stands at the top of the Kudan-zaka slope, that lies between the low alluvial plain and the Yamanote terrace.Img_3649s


ネットでは、Lighthouse と書いているページもあるようです。

Edo Castle 江戸城

The castles in Japan were built by numerous stones. We do not ask where those stones came from nowadays as they were built about four centuries ago. The photo shows the Tayasu Gate, one of the thirty-some square-shaped gates of the Edo Castle. The city of Edo, present day Tokyo, stands on an alluvial plain and a terrace of volcanic ashes and the nearest place with rocky ground is at least thirty kilometers away.


When I went to Ito city at the neck of Izu Penninsula the other day, I saw some left-over stones of the Edo Castle there. There were quarries in nearby mountainous areas and stones were transported from the port of Ito to Edo by ships. If we consider the volume of all stones usued to build the Edo Castle, we realize that the port must have been very busy in those days.
Feudal lords who were assigned construction work by Shogun had their family insignias inscribed on some of the stones for identification.

By the way, I have received e-mail from foreign hams to invite me to participate ham radio castles award programs twice or three times. I find that 241 castles in Japan have numbers assigned in the World Castles Award program. The Edo castle is JA-00010. However, many Japanese castles have spiral structures and it is often difficult to find clear boundaries. In addition, many of original boundaries such as moats and stone walls have disappeared due to the necessities of present urban life. Some more reserch and thinking seem necessary to start castles activation in this country.

Fishing Rod Case

The last winter was one that was prone to troubles for me. The OS of my PC and my radio tranceiver became unusable in two days. I fixed one of the minor troubles yesterday. The bottom lid of my fishing rod case fell apart when I was bringing it with a couple of FRP pipes in it. I applied a binding agent and covered the lid by pieces of an adhesive tape.

Img_3637ts Img_3641ts

I was obliged to buy this case five years ago, when I flew by Qantas taking fishing rods with me. The airline rule asked passengers to use hard cases for fragile rods. However, the case was useful to erect a vertical antenna higher.

Fishing Rod Vertical

I cut a PVC pipe and made a joint for my fishing rod vertical antenna on the balcony yestreday, and erected the vertical today. When I brought the antenna down last Tuesday to evade the forecasted gust, I found that the aluminum joint between the fishing rod and the 25mm diameter FRP pipe was not working well due to the disintegration of the grip part of the rod. Pieces of a cloth tape were used to adjust the diameter of the rod.


The photo below is the aluminum joint used previously. The fishing rod is a sample and not used in this project.


The total net height of the antenna is 685cm, 350cm long fishing rod, 155cm long 25mm FRP pipe and 180cm long 38mm FRP pipe. The antenna element is a vinyl coated wire and it has a resonant frequency of about 10.100MHz with a radial.

"The Iron Lady"

Am writing what I did almost two weeks ago. I saw the movie "The Iron Lady."

I had not kown much about Margaret Thatcher, but the mere fact of her premiership of eleven years and a half was very impressive, living in a country that had seven(!) prime ministers in the last ten years.

The movie makes me to wonder if we, the Japanese, are too concerned about consensuses among people and compromises to reach peaceful solutions.

The quotes below are picked up from the Inter-net afterwards, since I could not remember the sentences in the movie.

"People don’t think any more, they feel. One of the greatest problems of our age is that we are governed by people who care more about feelings than they do about thoughts and ideas. Now, thoughts and ideas, that’s what interests me."

"Watch your thoughts for they become words. Watch your words for they become actions. Watch your actions for they become... habits. Watch your habits, for they become your character. And watch your character, for it becomes your destiny! What we think we become."            

(Margaret Thatcher in the movie, "The Iron Lady")

少し前のことになりますが、映画「マーガレット・サッチャー 鉄の女の涙」を見ました。

Yokohama F. G. 横浜航空隊跡

The gate pillars in the first photo, shot last Sunday, were used by the Yokohama Flying Group of the Navy before and during WWII.


There used to be a big hanger for big navy flying boats such as type Kawanishi H6K, aka Mavis, and H8K, aka Emily in this base at the location of the big building that appears like a storage house in the second photo. The present built-up area in front of the hanger was the lighting area for the flying boats.

The flying boats departed here flew to the bases at Saipan, Mariana Islands; Dublon/Tonoas, Chuuk/Truk Islands, Caroline Islands; Rabaul, New Britain Island; Faisi Island near Shortland Island, Solomon Islands; Gavutu and Tanambogo Islands near Tulagi, Solomon Islands  and others.
From the front line bases, some flying boats performed reconnaissance and/or bombing missions to such distant places as Fiji, New Caledonia, New Hebrides Islands (Vanuatu,) Cairns, Horn Island, Port Moresby and others.
(The places in bold letters had my footprints.)

English Poem

There is a rare stone monument with an English poem inscribed on it at the beach of Ito.

We see countless stone monuments with Japanese tanka, haiku and other poems all over the country, but do not find English poems often.Img_3604s   

The poem is about William Adams (Anjin MIURA,) who came to Japan from England via the Netherlands in the 17th century, and composed by Edmund Blunden, also from England.

Ito, Shizuoka

I went to Ito City, Shizuoka, with seven elementary school classmates and a high school classmate last Friday.


The white light is the Ito Ko East Breakwater Light, ARLHS JPN-1430. Hatsu (Hatsu-shima) Island is on the horizen. There is a lighthouse on the island.
