The Dilemma of Digital
The Dilemma of Digital Spectrum Efficiency or Threat/Risk? de Jim Aspinwall, No1PC Preface This is NOT a piece critiquing specific technologies – one ‘better’ or ‘worse’ than another […]

A ‘problem’ appears. Could be a lamp doesn’t light. Car doesn’t start. Could be a ‘device’ doesn’t power up. Could be your receiver presents some noise/doesn’t hear some […]
More DetailsPart 4 – Antennas, Counterpoise and “The Law”: Antenna Impedance vs. Feedpoint Impedance
In the context of understanding and optimizing antenna systems we’ve been following the voltage and current paths of RF in two basic reference antenna types – the half-wave […]
More DetailsPart 3 – Antennas, Counterpoise and “The Law”: The LESS Than ‘Legal’ Antenna
Once, *IF*, we realize that the resonant wave pattern of an antenna is responsible for balanced, equal current transfer from one part of our radio-to-feedline, feedline-to-antenna, antenna-to-feedline, feedline-to-radio […]
More DetailsPart 2 – Antennas, Counterpoise and “The Law”: The Almost “Perfect Antenna”
I’m not one to be ‘casual’ about technical specifics, but once they all come together, when you see what they ultimately represent – is it 1 or is […]
More DetailsPart 1 – Antennas, Counterpoise and “The Law”: Current In Must = Current Out – Kirchoff’s Law and RF/Antennas
In a *very* casual way Kirchoff’s Law is the “what goes up must come down” rule of electronics – for a complete circuit to be complete, the current […]
