Our techs received this transmitter after it was dropped in the water and then run over by a truck. We opened the battery door and saw corrosion, and felt that it was likely the transmitter wasn’t worth repairing since it was crushed and corroded. However, we decided to test it for operation despite it’s appearance (and a small side wager was placed).
After cutting the housing off, the corroded circuit boards were powered up. Although it was out of spec (2dB low on RF power and 7kHz low in frequency), the transmitter worked!
