On February 5th, 2013, the Cuban numbers station widely known as HM01 struggled to maintain its composure following an awkward studio error.

In this particular case, I started recording a few seconds prior to the carrier, at which point you’ll hear a couple of minutes of “dead air” (silence). The broadcast starts around 2:25, cutting into the middle of a data burst; the station then goes silent before it comes back on at 5:15 with numbers, then abruptly stops. At 6:15 the station restarts the numbers broadcast in earnest.
