Low-Cost 2 MHz Transmitter for the Detection of Human Trapped Under the Snow

In an avalanche, terrain travel and recreation has many fundamental risks. At the time of accident when the rescue team is far away there is a minimal chance of survival. In an event of a full burial, when no visual signs exist, transceivers are used to locate a completely buried victim while he or she is still alive and are considered as the only viable way for detection of humans trapped under the snow. The system is used for tracking and identification to rescue people which are trapped under snow by their precise location. The design has been made for operating at 2 MHz rather than the standard frequency of 457 kHz since a frequency range from 450 kHz to 3 MHz penetrates the snow more than any other frequencies. A Class E power amplifier with a planar PCB antenna is connected in the design to improve the range of transmission for the detection. The main aim is to build a device at a reduced cost which is better than the available transceivers.
