Southern accented OMs talking about pumps and roads? With squelch crashes. Two-way radio relay?
Seems a carrier on 6927 kHz is being transmitted when there's no audio on the frequency, not sure if this is a low-frequency power supply hum or another signal underneath it. Talk at 1533 UTC about a "new hire" and "loading these trucks".
1535 UTC - "26.27" with sirens blaring in background. Sounds like construction site workers talking to each other on the radio
1540 UTC - OMs with Hispanic accent talking on radio with some noise in background
1542 UTC - "Naw, Billy, you're on channel 1"
1544 UTC - Data bursts overwhelming voice comms for a 1-2 seconds
1550 UTC - Off?
