Two Spanish-speaking OMs chatting away on another "offset frequency". One of them seems a bit off frequency (perhaps 6777.7 kHz USB?) but the stronger of the two is on 6777.50 kHz USB. Similar accents, signal strengths and operating practices to the stations usually heard a little higher in frequency. Very informal chatter (as is the norm). After listening for 10 minutes or so, no callsigns, ID, names or "handles" heard.
