So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project.

In this study, the Arduino is used to build a low-cost data acquisition card with its sampling frequency of up to 50k Hz, so sampling frequency can also be applied to adjust the signal measurement of ...

The range of the frequency to be measured by a measurement device depends on the purpose of performing the measurement. The frequency measurement device is built specifically according to its range ...
