11 meters is active 2130 UTC 7 May 2019

Mostly in-band AM and SSB activity with some South and Central American SSB DX heard on 27.520 MHz USB, 27.540 MHz USB, 27.555 MHz USB and 27.570 MHz USB.  27.385 LSB (channel 38 LSB) is also very busy.  Noted activity on 25.935 MHz AM, 26.035 MHz AM and several other low band (below CB channel 1) frequencies.  So far 26.915 MHz is quiet. 

The usual suspects AM big radio channels (6, 11, 15, 26, 28) are all wall-to-wall with big signals.  Heard Puerto Rico on 27.065 MHz AM (channel 9) as well.

It was a crazy fun evening. I think at one point I had carriers on all the CB channels. Lots of outband activity both above and below.

Including this Latin American splatterbox:

Super splatterbox!  26.715 MHz for sure (he looks to be closer to 26.716 MHz than 26.715 MHz on the waterfall).  Generally when you can hear Puerto Rico, the Dominican Republic and other Latin American/Caribbean stations on 27.065 MHz [CB channel 9] you can also hear them around 26.7 MHz. 

26.715 MHz is their AM calling channel, with 26.705, and 26.725 being the alternates.  Some of these stations are in Miami too, and they're running kilowatts.  Spanish language version of 27.025 / channel 6.  Looks like there was also activity on 26.595 MHz AM and the Latin American / Spanish language low channel SSB calling frequency of 26.555 MHz LSB.  26.585 and 26.575 are also popular (for AM mode stations).  26.555 LSB can have some real flamethrower stations on it.  Next time the band is rolling like this, check around 26.225 MHz.  26.225 to 26.255 in 5 kHz steps is another "watering hole" for SSB operators in Latin America.

That's the biggest signal I've seen on 26715 in a while though.

A while ago I found a Spanish 11 meter calling/working frequency list online and it went something like this:

26.225 MHz USB - Mexico/Caribbean/Latin America SSB
26.230 MHz USB - Mexico/Caribbean/Latin America SSB
26.235 MHz USB - Mexico/Caribbean/Latin America SSB
26.285 MHz USB - International 11m Freeband CB Calling (alternate to 27.555 USB) English and Spanish
26.500 MHz LSB - Caribbean and Latin America SSB
26.500 MHz USB - Caribbean and Latin America SSB
26.540 MHz LSB - Latin American SSB activity (alternate to 26.555 LSB)
26.555 MHz LSB - Latin American SSB activity (this is channel 4 down one band)
26.570 MHz LSB - Latin American SSB activity
26.585 MHz AM - Mexico/Latin America AM (Mexican trucker CB channel, channel 7 down one band)
26.595 MHz AM - Mexico/Latin America AM alternate
26.605 MHz AM - Mexico/Latin America AM alternate
26.695 MHz AM - Puerto Rico, Caribbean, Miami, etc (alternate)
26.705 MHz AM - Puerto Rico, Caribbean, Miami, etc calling channel
26.715 MHz AM - Puerto Rico, Caribbean, Miami, etc calling channel
26.725 MHz AM - Puerto Rico, Caribbean, Miami, etc calling channel
27.005 MHz AM - Latin American AM activity (CB channel 4)
27.065 MHz AM - Puerto Rico, Caribbean, Miami, Latin American AM (CB channel 9)
27.455 MHz USB - Latin American SSB activity (this is channel 4 up one band)
27.515 MHz LSB - Caribbean SSB DX channel (English and Spanish) (alternates up and down 5 kHz)
27.555 MHz USB - International 11m Freeband CB Calling
27.665 MHz USB - South America/Central America (LSB also)
27.675 MHz USB - South America/Central America (LSB also)
27.695 MHz USB - South America/Central America (LSB also)
27.705 MHz USB - South America/Central America (LSB also)

Of course, these are more like guidelines.  The gentleman's agreement is more or less this:  AM stations stay below CB channel 1 (with the noted exceptions around 26.2 MHz - 26.3 MHz and 26.555 MHz) and SSB stations operate above CB channel 40, with some exceptions (a big one being truckers using AM mode on any frequency they want).
