TrainPlotter decodes and displays these messages using the PC soundcard. You can use a simple UHF radio receiver (scanner) tuned to the appropriate band to pick up these messages. With TrainPlotter you can see the message data and find out the train's identity as well as such things as commands to increase or decrease speed, to set up a voice call or even to address the passengers. TrainPlotter decodes transmissions in UIC 751-3 format between Trains and Controllers using the sound card in your PC. You need a suitable UHF band radio receiver tuned to one of the Train data channels. The program decodes the received digital data and displays and logs the messages. The receiver must be tuned to the appropriate channel. The allocated bands differ slightly from country to country. The channel spacing is generally 25kHz."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
