Bill Jones, K8CU, has been an active Radio Amateur, CW Dxer, and home project builder since first receiving his Amateur Radio license in 1966 at age 17. Bill is an electronics professional with four-decades of experience.

High voltage regulated power supply for RF amplifiers. This is an enhancement of the article by VE6AXW in July/Aug 1999 QEX. I have redrawn the schematic for clarity, added EMI filtering, included a programmable power on timer, and generated a printed circuit board layout. Works for most voltage values.

"I was born in the late 1970s, mid-year in the local hospital of a coastal part of Australia? Yet another instance of humanity, one of the 6.6 billion or so of us (4.2 billion back then). Doomed like all of us to live out their days on this rock with some clinging gases orbiting a minor star in a relatively quiet part of the local cosmic clump of matter."

Engineering Calculators

One Transistor Voice Transceiver - Building a toy VHF phone transceiver for 3 metres using only one transistor for both TX and RX!

MK484 MW Receiver - A fairly small MK484 based receiver for the AM broadcast band.

40 Metre Spectrum Analyzer - My go at making a JF1OZL-style spectrum analyser for 40 metres.

Nano-Henry Inductance Meter - My implementation of Drew Diamond VK3XU's "Nano-L", plus how I constructed and trimmed my calibration inductances.
