Bug Tracker is a PHP  web based bug tracking system. It helps you manage software development. It uses a database to store issues to be done, bugs to be fixed, and features to be added.The bug tracer is made up of a simple rf-injector circuit consisting of Ql and Q2, and a pocketsize, AM broadcast receiver. The two-transistor rf-injector circuit supplies a constant rf signal to one end of a cable. Then the AM receiver is used as a detector, allowing you to trace the wire to its source. Transistor Ql, along with piezoelectric ceramic resonator RESl, make up a simple rf oscillator that operates either at or near the AM-radio, 455-kHz, i-f frequency.That means that the second or third harmonic signal can easily be picked up by the receiver. Transistor Q2 is connected to an emitterfollower circuit to protect the oscillator from output loading; that helps to stabilize the output frequency and signal level.Bug Tracker has two user interfaces. One is for internal developing team. The other is for customers or end users to report their feedback. It has flexible user/group permission management, database search/filter functions, FAQ and document management, and more.
