Logged these tones on 27.635 and 27.645 yesterday. Actual transmit frequency could have been 27.640. Any ideas? Someone playing around with an 'export' CB? SCADA?

Good work marvinsuggs! "ROS" rang a bell for me, I have a screen shot of it back in 2014, using HDSDR. Note that you have to subtract 125 MHz from the frequency shown in HDSDR, so it is actually 27.635 MHz. This signal is well above the CB band so who/what could it be?
Time to try and decode it, anyone find ROS decoding software? Might be good to try it out.
Thank u sir but Kevin Chessher gets all the credit! I think there's a link to down load the software on the message I posted 73s MarvinGood work marvinsuggs!

It's called "Free Banding."
Been going on for 50+ years. Neither the FCC in the USA nor the Mexican govt seem to care enough to enforce.
And it's understandable why they don't. It just doesn't matter.
Now, when the band is open, expect to hear lots of operators on 27.555 (the defacto calling freq) and more.
When the next sun cycle starts to edge up, you will hear tons of activity all over the "free band" every day.
Like the plague.
("Free band" is 27.410 to 27.995 and also below the CB channels)
