One of the Weakest DXers in the World
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 New DXCC No. 187 with QRPp 500mW/Dipole

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.

My New DXCC No. 186 with QRPp 500mW/Dipole

I sometimes call CQ with an output power of 500 milliwatts and a dipole.
For the first time, the Reverse Beacon Network (RBN) received my 500mW/DP signal today (Mar. 27, 2016).

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.
(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.

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

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 that day !!

Results of Contests


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).

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. Such distant DX stations I worked using 500 milliwatts and a dipole include EL2WW(Liberia), EA8BWP(Canary Is.), 5N6/YL2SW(Nigeria), FG5FR(Guadeloupe), YN7SU(Nicaragua), XQ6ET(Chile), MJ0ASP(Jersey Is.), MU/PA9M(Guernsey Is.), GW0ETF(Wales), EI0CZ(Ireland), SV9/DJ7RJ(Crete), LX1KC(Luxembourg), OH0/OK2BOB(Aland Is), etc.

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.

(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.

i) Shogi (Japanese chess) (5 "dan" in the amateur ranking system)
ii) Astronomy.
I am a citizen science volunteer for Galaxy Zoo. While classifying recently captured galaxy images provided by Galaxy Zoo, I enjoy observing and collecting images of beautiful and odd-looking galaxies, which are very distant and are 100 million to several billion light-years away from the earth (see My Galaxy Collection).

iii) I was good at skating (short-track speed skating).
iv) I enjoy table tennis.

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 and some 2-way QRP QSOs.
