    Frequency Radio
AI Thread Summary
To create a low-frequency radio that tunes between 1000 and 10000 Hz, one must consider the significant size and inefficiency of antennas required for those frequencies. Understanding the intended application is crucial for providing tailored advice. The discussion references a similar inquiry from the previous year, suggesting ongoing interest in this topic. Efficient design and practical implementation are key challenges in building such a radio. Exploring alternative methods or applications may yield better results.

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?

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
