At the dawn of my HamRadio life, I was active on 6m SSB. Even now, of course,
I love 6m band very much. During summer season, I often enjoy QRVing on 6m
band with a temporary antenna.
|
From 1983 to 1988, I was a member of
JA7YAA,
Tohoku University Amateur Radio Club, which was famous as a "Contest Gang",
however, I was not very interested in contests --- my interests were focused
on V/UHF and Satellite Communication.
|
|
In 1986, I came across Amateur Packet Radio and joined
PRUG, Packet Radio User's Group.
My interests then were gradually shifted to Packet Radio. Since 1992 to
1998, I had been running a TCP/IP Amateur Packet Radio Station as a branch
of AMPRnet-JA. During those days, I had been engaged in the development
of High Speed Packet Radio System, especially employing Spread Spectrum
technology, as a member of the
PRUG96 project.

Recently, I am facinated by the traditional HamRadio again.
Every now and then, I enjoy CW/SSB QSO on 20/15/10m bands, with a
barefoot transceiver and
small antennas mounted on a balcony.
|
|
On the other hand, I sometime enjoy long-distanse voice communication
using the combination of VoIP and HamRadio. I would like to continue
to touch new technologies for the next era of HamRadio, as far as
I have a chance.
