Several projects which will allow you to build your own RF design test equipment. -
This article appeared in the February issue of Amateur Radio and is reprinted here for the convenience of others -
A workbench instrument capable of testing transistors, diodes, FETs, usefull constructing QRP circuitry. -
Information on equipment manufactured by the Bird Electronic Corporation, wattmeters, RF loads, switches by I0JX -
Homebew a frequency marker by 7N3WVM -
This R.F. current meter was developed to assist in measuring line currents in balance feed lines as used in the All Band HF Antenna. -
A small and inexpensive measurement device designed to determine antenna performance across the amateur bands through use of automatically collected SWR readings -
A neat tool for your daily ham activities around the shack -
A field strength meter, a crystal tester and a capacitance meter by Peter Parker VK3YE -
This antenna anlyzer project was published in the May 2005 issue of the Australian magazine "Amateur Radio", and has been designed using parts which are very readily available -
A Neat Little Tool For The Bench. The basic information needed when testing a multi-conductor cable like CAT-5 is that each wire in the 4 pair cable goes to the correct pin in the RJ-45 plug and that all crimps are solid. -
An inductance and capacitance meter, measuring range is from 0 to >0.1uF for capacitance and 0 to >10mH for inductance. A project by Phil Rice, VK3BHR -
The article describes Q factor, methods of measuring Q factor, inductance and capacity using a Q meter and the design of an experimental Q meter unit. The Q factor or quality factor of an inductance is commonly expressed as the ratio of its series reactance to its series resistance. -
A polarity checker is a very useful item to have around the shack and in a go-kit. This project, inspired by a QST article on powerpole connector protection illustrate how to build a polarity checker. -
Do you want to measure antenna impedance at resonance? With this Antenna Scope, you have a simple RF Bridge for getting started in an exciting part of Ham Radio, building your own Antennas that work well -
Antuino is an accurate instrument that can be used in the field to measure SWR, field strength, modulation, etc. In the lab, it can be used to sweep filters, measure gain, distortion, frequency response, etc. It works upto 150 Mhz. On the third harmonic, it is usable on 435 Mhz band as well (with reduced sensitivity). -
A capacitance meter kit assembled. The meter measures from 1 picofarad to 500 microfarads with an accuracy of up to 1% and less than 2% -
