Introduction: HOMEMADE - DIY - LOW COST RADIO BEACON

Build a radio beacon with the material found in the house at a cost of few euros.

We start with the idea that digital radio audio signals can be recorded and then decoded. Among my channel videos you can see how to decode a digital signal found on youtube.

You can use countless software and protocols. Important is that you can generate the signal, transmit it with a radio transmitter, receive it with a radio and record it here. Then this audio will be retransmitted.

Below are some low cost examples:

1. FM Radio Beacon

2. AM Radio Beacon

3. Multi Channel Radio Beacon AM & FM

If you plan to use this system standalone you can associate an additional power generator (solar panels, wind power generator, hydro turbine, etc)

Good Fun.

Step 1:

FM Radio Beacon

Necessary material:

- MP3

- FM Transmitter Audio

Records one or more audio messages encoded with one or more protocols in succession in mp3 memory. You can create them with dedicated software directly from your computer's sound card, otherwise you can send them via radio, receive and record them. Do this you can send them via the FM audio transmitter connected to the MP3 audio

Step 2:

AM Radio Beacon

Necessary material:

- MP3

- DIY simple radio AM audio transmitter

Records one or more audio messages encoded with one or more protocols in succession in mp3 memory. You can create them with dedicated software directly from your computer's sound card, otherwise you can send them via radio, receive and record them. Do this you can send them via the AM audio transmitter connected to the MP3 audio

Step 3:

Multi Channel Radio Beacon AM & FM

Necessary material:

- MP3

- FM Transmitter Audio

- DIY simple radio AM audio transmitter

Records one or more audio messages encoded with one or more protocols in succession in mp3 memory. You can create them with dedicated software directly from your computer's sound card, otherwise you can send them via radio, receive and record them. Do this you can send them via the AM & FM audio transmitter connected to the MP3 audio
