“I record the 6800-7000 kHz band every night with my SDR, looking for pirates, but sometimes I also stumble on other interesting transmissions. The other night (UTC March 8) I picked up a curious station on 6974.5 kHz AM, starting at 0119 UTC, off at 0137. It was a mix of music and possible IDs by an OM in Spanish. There is what sounds like a four character call sign as part of the ID, and mentions of what could be the Dominican Republic. My guess right now is this was some sort of a relay of a domestic MW or FM station.
I have two recordings here, perhaps someone can pick out the callsign or other parts of the ID? Not the best audio quality, but you know how that goes:”
