Spanish voices heard on 6900 LSB and 6905 LSB
Frequencies: 6900 kHz 6.900 MHz 6905 kHz 6.905 MHz
Language: Spanish [Latin American]
Locations: Unknown, but likely land-based HF stations
and, of course, they are unidentified.
Heard a strong station transmitting on 6900 kHz LSB, followed by what appeared to be a request to QSY, then 6905 kHz LSB lit up. 6900 LSB remains active, two stations talking on 6905 LSB while 6900 LSB remains busy with the usual "roundtable" or ragchew style net usually found on this frequency.
on 6905 LSB: one station IDed as "Guillermo", then a third station checked in, Guillermo wished him a good morning and gave him a signal report. While all this is going on, I am seeing nearly constant activity on 6900 kHz. The use of 5 kHz steps is pretty common with this group, they tend to start on 6900 LSB (sometimes 6900 USB) and then move plus or minus 5 kHz because of QRM or for a "side channel" to have a long QSO without tying up the calling frequency of 6900 kHz LSB. At 1454 UTC, Guillermo IDed as "del Norte" (of the North or from the North - of course that's meaningless without context). Lots of noise making complete copy impossible.
These operating procedures are basically the same as amateur radio or 11 meter freeband SSB operators...chances are these guys do all of the above.

At 1458 UTC, a third group of stations popped up on 6900 USB, causing some QRM with the on-going QSO on 6905 LSB...after 20 seconds or so, the third group switched back down to 6900 LSB.
These guys are more professional than some ham operators...
