The BRAHMS collaboration has measured identified particle spectra from Au+Au collisions at GeV. Rapidity densities are deduced from fits to the pion and kaon spectra. dN/dy is plotted as a function of rapidity and 4π yields and ratios are calculated. The signed K/π ratios are compared to values obtained at lower energies. We find that K
–/π
– increases monotonically from the AGS and SPS regimes, while K
+/π
+ is similar to what was found at the highest 
at SPS.
