100% CW MILLIWATTER
I enjoy QRPp DX on CW 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 dipoles.

NEW !!
LoTW QSL of NP4G (Puerto Rico), confirming the amazing QSO made using 500 milliwatts/Dipole
Surprisingly, his 5-element beam antenna was toward the side direction (Yemen), according to an e-mail from him.

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)
The following images are from their QRZ.com pages or websites (Click to enlarge).
I have received the following beautiful award as well as the following eQSLs and LoTW QSL.

An Audio File of My QRPp(200 milliwatts + Dipole) Signal Recorded by SM4OTI
This audio file shows a QSO with SM4OTI on October 9, 2011, 1010UTC, on 24892 kHz, CW.
SM4OTI (Steve in Sweden) recorded the QSO and sent the recorded audio file to me (Thank you, Steve !).
In the QSO, using an output power of 500 milliwatts, I called him, and sent his RST, my name and equipment.
After that, I increased my power to 10 watts.
At this time point, he started recording the QSO.
In this audio file, my signals at 10 watts, 500 milliwatts and 200 milliwatts have been recorded.
SM4OTI' equipment: K3, 1KW, 4ele yagi 40mH.
JQ2UOZ' equipment: IC-7000S, Dipole on my apartment balcony 20mH.

About Me
I am a member of Solar Stormwatch and Galaxy Zoo.
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, contest serial number, 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.

私はアマチュア無線家です。モールス符号を使って世界中のアマチュア無線家との遠距離通信を楽しんでいます。特に、携帯電話と同程度の僅か500ミリワットの微小送信出力と単純なアンテナによる電離層利用遠距離通信を実験しています。
私のブログで扱う遠距離通信は電離層を利用したものです。中継局や人工衛星や有線回線は用いていません。電離層は、電波を反射して地球の裏側までも到達させる (場合によっては地球1周させる) という驚くべき性質を持っています。電離層を利用する遠距離通信に関しては謎が多く、最先端の科学においても十分に理解されているとは言えません。特に、500ミリワットのような微小送信出力での電離層利用遠距離通信については、その実例すらほとんど示されていません。
