SUMMARY

To create a low-frequency radio capable of tuning between 1000 and 10000 Hz, one must consider the significant size and inefficiency of antennas required for these frequencies. The discussion highlights the challenges associated with low-frequency radio design and suggests that understanding the specific application is crucial for effective implementation. Previous threads on similar topics indicate ongoing interest and complexity in this area.

can someone tell me how to make a radio that would tune between about 1000 and 10000 Hz please. ? Or at least where to begin.

Welcome to the PF.

The antennas for those low frequencies would be prohibitively large, or at least very inefficient. What is the application?


EDIT -- This looks similar to your thread from last December:

Is it for a different application?
