The NRL and the NRAO have jointly implemented a low frequency capability on the Very Large Array. Operating at 73.8 MHz, this new frequency band offers unprecedented sensitivity (∼ 25mJy/beam) and resolution (∼ 25″). This paper briefly describes the this new receiving system, and the methodology for using it for astronomy.
