What's the purpose of changing frequencies like that?From back on January 4:
Today's NOTAM extends the decommissioning of 126.3 and its replacement 124.275 until March 31 2023.
Also reminds me: last night for some reason DCA's UHF 257.6 and VHF 119.1 were patched, and UHF 133.525 and VHF 121.7 were patched for a short while.
