Profile of JN1DNG
Name : Yoshihisa Kawamura (Hawk)
Born : In 1952 in Gifu prefecture
Personal history
When I was a kid, I was a notorious brat,
disassembling radios and clocks often. I
never had any success in making them work
again. This superheterodyne brat later became
a radio boy. A radio boy finally became a
radio operator. I have been casually involved
in ham radio for 30 years. Although I always
have had a certain dream for my radio life,
this dream has never come true. I have never
run high power and done DXing openly.
1952 Born in Yaotsu-cho Kamo county in Gifu
prefecture, about 40 km North North East
of Nagoya city.
Yaotsu-cho was called Nishiki village in
Kami county at that time.
circa 1961 When I was in the third grade
at elementary school, I made a germanium
radio.
But no broadcasting stations were heard,
just strange conversations instead.
Later these were found out to be ham radio
operators' voice on 3.5Mhz.
circa 1962 I found that a ham radio uses
3.5Mhz. I had a strong desire to become involved
in ham radio by all means at that time.
Unfortunately, I did not know how to take
an exam.
1965 I entered junior high school and I belonged
to a baseball club.
The baseball club activities made me forget
about a ham radio
completely.
1968 Just after a graduation from junior
high school, I took an exam for Phone and
CW class
and passed these exams. I received the call
sign of JA2QXY and built a ham radio station
with a homemade
RF1/IF2 receiver and an 807 x1 transmitter.
I belonged to a radio club (JA2YFE) at high
school. This radio club had a very severe
policy towards CW techniques.
Those who can't do CW (both Alphabet and
Japanese characters) can't be eligible for
this club.
A club senior JA2KSG, also known as a demon,
trained me in CW. Another club senior,
JA2HKB who had a professional radio operator's
license and joined the Japanese FCC after
graduation trained me CW
for Japanese characters. Since I was really
vexed, I practiced CW very much and as a
result, my CW techniques for Japanese characters
became much better than those of JA2KSG.
After learning CW for Japanese characters,
I took an exam for the second and first class
ham radio operator licenses. Since I did
not study at all,
I just passed the second class exam. Later
I was able to pass the first class exam.
It is often said when one thing goes well,
another thing also goes well, too. I passed
the professional radio operator's exam and
professional radio
engineer's exam at the same time that I passed
the first class ham radio exam.
When I was a third grade high school student,
I really wanted to operate SSB. I managed
to get a mechanical filter with all the money
I had at that time. Since I had only one
filter, I had nochoice but to make a transceiver.
The final tubes were 2 x 2B46. But no signal
was heard on 21Mhz and above. Since then,
I hated 21Mhz.
( Of course not due to 21Mhz itself, but
just due to lack of my engineering skills)
I feel that this was the most perfect time
for my ham radio life.Because I was not making
any money at that time,
I was just fed by my parents and I did not
have to care for my financial situation
1971 I started to live in Tokyo after persuading
my mother that the stay in Tokyo will be
only four years and the purpose of my stay
will be for study. Instead of studying, I
knocked on the door of the founder of Yaesu
Musen,
JA1MP and started to work for Yaesu as a
radio engineer.
1980 I devoted myself to DXing on 40m with
a GP antenna together with JG1XLV.
Since my job was changed at that time, my
radio life did not continue steadily.
I was using a linear amplifier with the callsign
of JA2QXY/1. However, a portable station
is only allowed
50W output power. I felt that operating illegally
was not so good.
Later, I received the callsign of JN1DNG.
I really wanted to receive JN1A**, but I
failed to get this type of callsign.
My wife applied for a callsign two weeks
earlier than me and received JM1W**. I should
have applied for a callsign
a little bit earlier. My casual radio life
continued.
circa 1986 Although I was working for an
electronic company , my job had nothing to
do with a transmitter.
Since I had a strong desire to build ham
radio gear, I started off by making a transceiver.
I worked very hard to complete it using some
pieces of measuring equipment in
the company every night after work. I went
back home around midnight, or after midnight
everyday.
Just in case you may misunderstand this,
the reason that I went home very late everyday
was not from having
visited night clubs to see nice babes, but
I was concentrating on making a transceiver.
1993-94 Through the usual radio communication
activities, I met up with
some nice guys who were always looking for
a good sound, a strong signal, and a signal
that lures other hams attention. These were
the original targets of TGC members.
1995 TGC was established. I was one of the
original eleven members.
