NRAO, with the assistance of astronomers and engineers from the Naval Research Laboratory, has installed a 74 MHz receiver and a removable dipole on the Pie Town VLBA antenna (PT). Recent brief tests of this system show the VLA-PT link appears to work as expected at a frequency of 74 MHz. The major importance of the link for scientific observations is the factor-of-two improvement in angular resolution for sources with declinations north of about +40 degrees (12 arcseconds at 74 MHz), while maintaining the full sensitivity of the VLA (about 50 mJy/beam for a full track at 74 MHz). We will discuss the scientific and technical aspects of this exciting new capability, now open for proposals in the upcoming A configuration.
