The Chelsea Amateur Radio Club sponsors training and technical information publications of interest to the amateur radio community. This page will be updated as new information is added.
An Electric Fuse Model for Computer Simulation
Wes Cardone (N8QM) developed a computer simulation model for the electrical fuse some years ago. The plan is to submit the article (fully written as of the time of this writing) to the ARRL QEX for publication after his wire simulation model is published. Since the purpose of a fuse is to protect a subject wire, the applications for the use of this model would be quite limited without a wire model (see below).
An Electrical Wire Simulation Model for LTSpice
Wes Cardone (N8QM) has developed a computer simulation model for electrical wires which is described here in rough terms. The plan is to write a detailed article for submission to the ARRL QEX magazine. However, it may be possible to write up the model in such a fashion that it may be picked up by QST.
Wire Characterization Tables and Data Sheets
A table of reference links will be shown here useful for the characterization of wire models for simulation.
Diode DC Characterization for LTSpice
The ARRL magazine QEX is publishing an article written by our own Wes Cardone (N8QM) which is currently scheduled for the March/April edition of 2023. Page 1 is shown here. After publication, we will likely put up the whole article here.
What the heck is characteristic impedance, anyhow? You will be amazed at what you can grasp once you understand what characteristic impedance represents and how it does it.
Why Coax and Not Hookup Wire
Did you ever wonder what the magic formula was for when to use coax and when hookup wire is okay?
