I have received reports from Panama noting an interruption or change in the usually reliable daily schedule of the Cuban numbers (V2a and M8a). Specifically, the frequency used at 1800 and 1900 UTC, namely 8097 kHz AM, is apparently dead. Nothing is heard here in California either.
Cuba does not suspend its "numbers." It runs dummy messages or repeats old ones with incrementing callup groups. Its sloppy engineering would, in fact, seem to suggest that most messages simply do not have a high priority, despite several high-profile busts indicating that deep-cover recruits in the US do receive and use them.
It's time to start checking for any possible new frequencies for the 1800 and 1900 skeds.
