We present recent improvements to the search for the global Cosmic Dawnsignature using the Long Wavelength Array station located on the SevilletaNational Wildlife Refuge in New Mexico, USA (LWA-SV). These improvements areboth in the methodology of the experiment and the hardware of the station. Animproved observing strategy along with more sophisticated temperaturecalibration and foreground modelling schemes have led to improved residual RMSlimits. A large improvement over previous work using LWA-SV is the use of anovel achromatic beamforming technique which has been developed for LWA-SV. Wepresent results from an observing campaign which contains 29 days ofobservations between March $10^{\rm{th}}$, 2021 and April $10^{\rm{th}}$ 2021.The reported residual RMS limits are 6 times above the amplitude of thepotential signal reported by the Experiment to Detect the Global EoR Signature(EDGES) collaboration.
