JQ2UOZ's QRPp DX

Welcome




One of the Weakest DXers in the World
THANKS TO All WHO WORKED ME !!
This website is to praise DX Stations who worked me, for their excellent ears, skills and patience.


I enjoy QRPp DX using an output power of 500 milliwatts (0.5 watts) and dipole antennas.


The green circles in the above map show the locations of the stations whom I worked using 500 milliwatts and dipole.

My Websites for Morse Code Practice:


Recorded Audio of W1AW Qualifying Runs
Special Training to Copy Hard-to-Copy Words in Morse Code
Common Letter-Groups in Morse Code
1000 Most Common English Words in Morse Code
For me, the object of this practice is to obtain ARRL Code Proficiency Certificate at 40 WPM.
I believe that the above four websites are very helpful to improve your head-copying and type-copying (with a keyboard) or handwriting-copying skills as well as to obtain the ARRL Code Proficiency Certificate.
(Note: Although this practice is focused on word-based copying, I think that sentence- and context-based copying is also important. Of course, listening to actual CW QSOs on the air is far more important for practice for CW QSOs.)

Surprisingly, RI1FJ (Franz Josef Land) successfully received my QRPp 500mW/Dipole signals to work me on 10m, 12m, 15m and 17m.
Great ears !!

My New DXCC No. 187 with QRPp 500mW/Dipole

Great ears !!

Thanks to the operator G4FNL for receiving my 500mW/DP signals.
Also thanks to good luck. The propagation conditions were excellent for an instant.
He successfully copied my callsign after I sent my callsign only twice.

Great Circle Chart and Gray Line vs. My QRPp/QRP QSO Data

My Output Power: 0.5W (500mW) unless otherwise indicated
My Antenna: Dipole (1999-2005, 2006-2010, 2011-Now)

(1) These charts were generated using DX Atlas created by Alex Shovkoplyas, VE3NEA. The original images are more beautiful.
(2) The smallest circle on the chart represents a distance of 3,000 km from the center (i.e. my QTH), and the second smallest circle represents 6,000 km, and so on.(Click to enlarge)

(3) An estimated propagation path is shown as a straight line on the chart, though the actual path may not be straight.
(4) Where the propagation path is estimated to have been a long path based on the DX station's message or information on the Web, etc., the path is shown as a long path on the chart. Some of the paths which are shown as a short path may have actually been a long path.
(5) The QSOs before the year 2005 were made using my previous 3-area callsign (not shown).
(6) The charts represent low energy-loss propagation because most of the QSOs shown were made using a very low power level (500 milliwatts) and a dipole antenna. I do not know very well the exact relationship between the gray line and the radio propagation on higher HF bands, but I believe that the gray line is one of the important factors for low energy-loss propagation even on higher HF bands.

AFRICA

I was ED9Z's First Japan on 21MHz in 2012 CQWW CW Contest.

QSL Card of 7X4AN (My first Africa with 500mW/DP)
Great ears !!
EL2WW's antenna was a broad-band dipole(1,2) according to his mail (My dipole for this QRPp 500mW QSO was this). Please note that, about 20 minutes after this QSO, I made a QRPp 500mW QSO with EA8BWP (see above), who was also using a dipole according to his QSL. Amazing band conditions on the day !!

A QSL CARD FROM A VERY RARE ENTITY FOR ME



I have just received the above QSL card from FG5FR, Frantz in Guadeloupe, whom I worked using an output power of 500 milliwatts and a dipole.
Guadeloupe is located at the eastern edge of the Caribbean Sea, which is the most difficult area to work from Japan.
As shown in the card, he was using "D3W" antenna, which is probably a rotatable dipole from Cushcraft.
Surprisingly, he successfully received my very weak 500 milliwatts/dipole signal using the dipole !!
Thanks to Frantz for the memorable contact I will never forget (Oct. 20, 2011).

Using an output power of 500mW and a dipole, it is very rare and difficult for me to work distant DX stations who are using a simple antenna such as a dipole or vertical.
Distant DX stations who were using a dipole or vertical and whom I worked using 500mW and a dipole include:
EL2WW(Liberia)
EA8BWP(Canary Is.)
5N6/YL2SW(Nigeria)
FG5FR(Guadeloupe)
YN7SU(Nicaragua)
XQ6ET(Chile)
MU/PA9M(Guernsey Is.)
SV9/DJ7RJ(Crete)
LX1KC(Luxembourg)
OH0/OK2BOB(Aland Is), etc.

MORSE MEMORIAL STATIONS
In 2011, a number of Morse memorial stations were QRV to celebrate the 220th anniversary of the birth of Samuel Morse.

Using 500 milliwatts and dipoles, I worked the following Morse memorial stations.

SQ0MORSE (Poland; Apr. 29, 2011, 15m, CW)
DA2MORSE (Germany; May 5, 2011, 17m, CW)
M0RSE (England; Oct. 22, 2011, 10m, CW)
8J1MORSE/2 (Japan; Nov. 8, 2011, 10m, CW)
EM0RSE (Ukraine; Dec. 2, 12m; Dec. 3, 10m; Dec. 24, 15m: all in 2011 and on CW)

I received the following beautiful award.

豆知識:
サミュエル・モールスは1791年生まれ、1872年没。本職は画家であった。
日本では江戸時代後期。
『遠山の金さん』や『江戸を斬る』の主人公のモデルとして知られる遠山景元は1793年(寛政5年)生まれ、1855年(安政2年)没で、ほぼ同時代。
日本では明治維新後、電信の導入が非常に迅速であった。1870年(明治2年)には、東京・横浜間で電信による電報の取り扱いが始まり、1871年にはロシアのウラジオストクから長崎へ海底ケーブルが敷設され、シベリア経由でヨーロッパ、さらには大西洋横断電信ケーブルを経て米国とも通信が可能となった。遠山の金さんの没後わずか16年のことである。
なお、CW愛好家の間ではサミュエル・モールスのみが神格化されているが、それ以外の多くの研究者や技術者もモールス符号の制定や電信技術の開発に大きな貢献をしたようである。

ABOUT ME

(1) About Me
i) Name: AKI
ii) QTH: Nagoya-city, Aichi JAPAN
JCC#2001, Grid Square PM85
iii) Born in 1965.
iv) Ham since 1975.


(2)OTHER HOBBIES:
i) Shogi (Japanese chess) (5 "dan" in the amateur ranking system)

ii) Astronomy
As a citizen science volunteer for Supernova Hunters, I have so far discovered 243 new supernova candidates including SN2018clq (In the bottom of the page, "jq2uoz" is shown as one of the volunteers who discovered the supernova candidates).
The following images (left and right) shows the supernova SN2018cjn that I identified in the project. The supernova is not shown in the middle image because the middle image was taken before the supernova explosion. This supernova is about 1.3 billion light-years away from the earth (redshift = 0.1). That is, this supernova exploded about 1.3 billion years ago, and the light generated by the explosion traveled through space for 1.3 billion years and has just reached the earth. I was the first person in the world to identify this supernova.

(The left and middle images are from https://star.pst.qub.ac.uk/ps1threepi/psdb/candidate/1184620411704413400/, and the right immage is from http://legacysurvey.org/viewer?ra=281.5850&dec=70.7369&zoom=14&layer=dr8)

If you are interested in galaxies, please see My Galaxy Collection which is my collection of galaxy images published in the project Galaxy Zoo.


iii) I was good at skating (short-track speed skating).

iv) I enjoy table tennis.


(3) MY QRPp POLICY:
i) I use an output power of 500 milliwatts to call a target DX station.
In "599 BK"-style QSOs, I maintain my output power at 500 milliwatts until completion of the QSOs.
In non-"599 BK" style QSOs, after confirming that my callsign has been correctly copied and after sending his/her RST at 500 milliwatts, I sometimes increase my power to 5 watts or 10 watts (my maximum power) to send my name, QTH, RIG, ANT, WX, etc., depending on the band conditions.
I consider the contact as a QRPp contact at 500 milliwatts.

ii) During the solar cycle maximum in 1999-2002, I enjoyed QRP at 5 watts.
But now I do NOT use an output power of more than 500 milliwatts to call DX stations, except for DX QSOs on low bands, some contests, some 2-way QRP QSOs, etc.
