There is no simple answer to this question which is often asked by newcommers to the hobby. But we can suggest a basic list:
|
Digital Voltmeter
|
Frequency Counter |
Signal Injector |
Noise Bridge-Simple type |
Small AF Amp probe
|
Absorbtion Wavemeter |
This list may look exotic but most of the items can be built for very little expenditure, and a number of these items have been described in SPRAT (The Quartely journal of the G QRP Club) and in Radio Communication (RSGB)
