1430MT would be 2030Z
. Presuming "two days ago" was Tuesday 9/18, I listened to the hourly material for the entire 2000Z set for Denver Center Low
, which includes the TRACON frequencies for the area SE of Denver, as well as 121.5.
There are a lot of frequencies on that feed, so continuity of conversations is tough, but I heard nothing I could relate to this incident.
Was it indeed on Tuesday 9/18 around 2:30pm in the afternoon, local time?
