Absolutely. During the 2011-2014 or so time frame, I got really into 11 meter and VHF low band DXing because the band was rolling on a regular basis back then...since so much of the traffic I heard was Spanish, I did some research and came across a significant amount of Latin American CB or 11 meter radio clubs (some of which even include the female taxi cab dispatchers sitting behind a RCI-2995 somewhere in Mexico). Several of these clubs list 27065 as the "in-band" Spanish speaker AM calling frequency.
I remember when I could hear the same taxi lady on 27.515 MHz AM reading telephone numbers, call numbers and addresses on a nearly daily basis. When the band was really open I could hear the taxi drivers responding to her on the same frequency...tuning lower in frequency I realized that the majority of taxi companies using 11 meters were using the lower frequencies in the 25.615 MHz to 26.055 MHz "A" band and the 26.055 MHz to 26.505 MHz "B" band to avoid the massive amounts of QRM on the higher frequencies. The YL on 27515 AM must be running power with a good antenna, because 27.515 MHz is also the Caribbean SSB DX calling frequency in LSB mode. Lots of powerful Jamaican stations (anyone remember The Knight Patrol?) booming in on 27515 LSB while she read number after number in Spanish in AM mode right underneath the Jamaican guys.
These taxi companies were found all over the band during a serious opening. They'd be using the A channels (I heard a very strong one using 27.045 MHz AM, which is channel 7A or even frequencies closer to 28 MHz. 27.995 MHz AM was even logged once. Anything to get a clear frequency. Mexican truckers could be heard well into 10 meters during those types of openings, 28055, 28065, 28085, 28105 and lots of others were popular, all in AM mode.
