Radio Frequency Network Analyzers is one important tool required for testing the frequency response of filters and networks, but as we all know, buying a regular RF test equipment can be quite the expenditure. This was why hobbyist Stephen Merrifield, who after seeing the increased need...

Brett Killion has published his Arduino shield a Network Analyzer on an Arduino Shield which covers from 0-72MHz. The network analyzer shield uses an Analog Devices AD9851 DDS chip clocked at 180MHz which will output a sine wave at any frequency from 0Hz and 72MHz. The DDS output is...

diycrap.blogspot.com has build a SWR and power meter based on Arduino Nano and LCD display: First of all, this SWR meter in this article is not exactly homebrew, as I based the circuit on the schematic in the excellent book Arduino Projects of Amateur Radio. Although I bought the...
