An Introduction to Andrew ZL2PD
Some information about the person behind this
website, if anyone is even remotely interested!
been an amateur radio ("ham") and electronics enthusiast since the age
of 13 when I built my first one-transistor radio with help from my
uncle, also a ham. A year or so later, I passed the New Zealand amateur
radio theory exam, and got my first 'Technician class' callsign
Like many, I built my first transceiver. It
was a 2m (144 MHz) AM transceiver. Back in the early 1970's, AM on VHF
bands was very popular and that technology, although considered
antiquated now, is still a relatively efficient spectrum modulation
method, especially for VHF bands.
Within a few years, and with a move to another city, I passed the
amateur radio morse test, and received the upgraded callsign - ZL1AQW.
Those were the years I finished school, and went on to graduate from
university with a degree in electrical engineering. That led to another
change of city, where I received my current callsign, ZL2PD. That's the
callsign I've held to this day.
Electronics is a great hobby. It's one I was also fortunate enough to
turn this hobby into a professional electrical engineering career.
After graduating from university, I worked for the Civil Aviation
Division of the Ministry of Transport, a New Zealand government
department. It was excellent experience, with work including
interference analysis on air-sea rescue boats to the design and
building of extensive high power HF transmitter/receiver systems for
Air to Ground communications, and to support long distance weather
facsimile ("fax") HF transmission systems.
After seven years in that job, I moved on to work on contract in Fiji,
an island group in the middle of the Pacific, doing a variety of HF,
VHF and UHF projects, and a bit of ham radio in my spare time. A few
years (and a military coup) later, I returned to New Zealand to work
for a mobile radio manufacturer for some years.
With my promotion to the head of the Systems Division of that company,
I led the design team responsible for building many hundreds of radio
and control systems across the world. Following that job, I went on to
work for a US-based multi-national network operator, designing
and launching a number of large mobile radio networks all around the
This led to a lengthy period as an independent telecommunications
consulting engineer. In that role, I spent much of my time travelling,
all over the world, helping to design, build and operate a variety of
new telecommunications networks.
Most of these are wireless networks. I've been involved in the
development now of over thirty new fixed and wireless networks rnaging
from W-CDMA and cdma2000 (3G), GSM and cdmaOne (2G) cellular networks,
fixed WiMAX and mobile broadband wireless systems, TETRA and MPT1327
trunking systems, and a whole bunch of others.
I am not very active on the ham bands these days. Part of the reason
can be blamed on my continued extensive travels. Since I prefer
operating on the HF bands, it's not so always easy to take ham
transceivers to some of the countries where I work and live for lengthy
periods. But I do spend time working on a project or two, writing
software, or working on some hardware designs.
When I am home, I enjoy spending time in my workshop, designing and
building all sorts of electronics equipment. Most of the focus is on
things related to amateur radio, but some circuits are built for use on
my model railway, or for my family.
