fredreload Posted August 18, 2016 Share Posted August 18, 2016 So, I dunno, I just want a device where I can broadcast my own signal all day, from my laptop, like data signal, what device am I looking for? Link to comment Share on other sites More sharing options...
studiot Posted August 18, 2016 Share Posted August 18, 2016 So, I dunno, I just want a device where I can broadcast my own signal all day, from my laptop, like data signal, what device am I looking for? A Radio Amateur's Licence? You would need some sort of licence to do this. 1 Link to comment Share on other sites More sharing options...

Your laptop can probably transmit Wi-Fi and Bluetooth already. You can buy a GSM (cell phone) dongle. And probably other protocols I am not aware of.

Strange Posted August 18, 2016 Share Posted August 18, 2016 I want to program and send my own custom signals. Can Wi-Fi and Bluetooth do this? If so how? In that case you will need to use a general purpose radio module such as: http://www.ebay.com/bhp/433mhz-module I think 433 MHz is licensed (in some countries) to general purpose, low-power use for remote controls, etc. Link to comment Share on other sites More sharing options...
Sensei Posted August 19, 2016 Share Posted August 19, 2016 (edited) Alternatively you can dismount broken (or new) remote controlled toy, or radio controlled computer mouse. I would not bother too much about license, if it's low power signal, which would work only inside your room, few meters around transmitter (like it's the case in remote controlled toy car).

rangerx Posted August 19, 2016 Share Posted August 19, 2016 Anything less than 1 watt is not regulated. I suppose it depends on what you want do listen with, a standard radio or a standalone device.. like a scanner etc.. There are several devices that play mp3 players etc. over car radios. You might also consider a micro broadcast transmitter https://en.wikipedia.org/wiki/Micropower_radio -1 Link to comment Share on other sites More sharing options...
Klaynos Posted August 20, 2016 Share Posted August 20, 2016 Depending on where you live you can probably broadcast low power on some limited frequencies. An easy way to interface with a computer is via an arduino or rasp pi. Google arduino 446mhz... Anything less than 1 watt is not regulated. Do you have a source for where in the world this is true?

Enthalpy Posted August 22, 2016 Share Posted August 22, 2016 Anything less than 1 watt is not regulated. Very wrong. Link to comment Share on other sites More sharing options...
Mordred Posted August 24, 2016 Share Posted August 24, 2016 Very wrong. Correct however every country should have a range of amateur radio frequencies. Check your local regulations. Link to comment Share on other sites More sharing options...
