This report describes a circuit for driving a low-frequency loop antenna from a miners cap lamp battery. The circuit is a miniature waveform generator and is part of the electromagnetic (em) trapped miner location system. Two engineering models were designed, constructed, and tested, and 50 final production units were fabricated using discrete component construction. A final discrete potted printed circuit configuration was developed that is now ready for field testing.
