These are older pdf versions of articles on the vk3ye dot com website. They were generally written in the 1990s - 2000s so some details may be out of date.
However they should still provide a useful background, especially for the beginner.

About Peter Parker VK3YE
I (mis?)spent my youth at rubbish tips, taking apart given radios and TVs and building electronic projects that mostly did not work.
Early projects were built with screws and breadboards until I realised that good soldering needs new soldering rather than that reused from terminal strips in valve (tube) radios.
Milestones included the construction of a crystal set in 1980, discovering shortwave broadcasting on a valve receiver in 1981 and a simple 'electronic organ' in 1982 from a Dick Smith Fun Way book.
Hours were spent putting wires into springs on a Tandy 150-in-1 electronics set. Amazingly some wires could be pulled out and the project would still sort of work with only half the parts in circuit.
Two back to back AM/shortwave radios led to the discovery of amateur SSB activity and a novice licence in 1985. The following year was spent building transmitters no one heard.
A one valve crystal controlled CW transmitter from the 1973 ARRL Handbook provided the first contacts - mostly CW/SSB crossmode on the 3.579 MHz TV colour burst crystal frequency.
The value of frequency agility was an early lesson and various VFOs were built, most of them drifty.
My gear improved in the 1990s, with more bands, more modes and smaller cases. Projects included a 7 MHz VXO CW direct conversion transceiver, 2m FM portable transceiver, and a 14 MHz CW transmitter
for Cycle 22, then near its peak. Later favourites included HF DSB and SSB transceivers (often using ceramic resonators, ladder crystal filters, NE602s and BD139 transistors) and phasing SSB equipment.
I've never had huge amounts of space at home. This led to experiments with magnetic loops and HF pedestrian mobile. The joys of the latter (along with the perils of a trailing counterpoise) were
first discovered with a converted Johnson Viking CB on 28 MHz. This was mounted in a carpeted chipboard box with battery and 1.5 metre whip. A move to a beachside suburb brought further HF portable and
pedestrian mobile activity on more bands. Below I'm about to go beach HF pedestrian mobile with the 7 - 50 MHz HF Wadetenna (described elsewhere).
Numerous articles on QRP, homebrewing, antennas and for beginners to amateur radio.
