The first radios were untuned radio telegraphs that broadcast a burst of radio static generated by a powerful arc when keyed. The receiver used a device called a coherer to detect this burst of radio static and activate the telegraph sounder.
It took the development of vacuum tube triodes to modulate radio waves with voice and music as well as provide tunable radios.
Armstrong invented improved receivers like the Superheterodyne and improved modulation techniques like FM that rejected static and noise.

What is the radio code for Volvo S40 2000 if you dont have the manual after changed a dead battery and radio does not work?
Volvo S40 radio codeEach radio has a different code. You need to call a Volvo dealership and read them the vin number and they can pull the code up for you. However, in certain cases (like the one I find myself in currently), the radio in the car is not the original and therefore will not match the VIN. This happens sometimes when you are not the original owner. In this case, you will need to get someone (or do it yourself) to remove the radio and find the serial number. Once you have it, you can call a dealer and get them to look up the corresponding code. One other thought - on my 1999 V70 I was able to pop out the radio and the code was written on top of the radio.
