How much work is it to modify an am radio to receive low frequencies 10 to 200 hertz ?
mgb_phys said:Less effort than running the 300,000km antennae wire.
That frequency is very specialized technology are you trying to communicate with submarines or miners?
The purpose of modifying an AM radio for low frequency scanners is to expand the frequency range that the radio can pick up. AM radios typically only go up to 1600 Hz, but by modifying it, it can pick up frequencies as low as 10 Hz.
You will need an AM radio, a low-pass filter, and a frequency converter to modify an AM radio for low frequency scanners. The low-pass filter is used to remove unwanted higher frequencies, and the frequency converter is used to downshift the frequency range to be within the AM radio's capabilities.
It can be a moderately difficult process, depending on your level of technical expertise. The process involves opening up the radio, soldering some components, and adjusting the radio's tuning circuit. Some people may find it challenging, while others may find it relatively easy.
No, not all AM radios can be modified for low frequency scanners. The radio must have a built-in oscillator circuit to be able to tune to lower frequencies. Additionally, the tuning circuit must be adjustable in order to fine-tune it to the desired frequency range.
Yes, there are some risks involved in modifying an AM radio for low frequency scanners. Opening up the radio and making modifications can potentially damage the radio if not done carefully. It is important to have a good understanding of electronics and to follow proper safety precautions when attempting this modification.
