I run across this quite a bit and I wonder what it is? Sounds like icecream trucks from hell

Also I heard aero comms on 3452 and 3455khz usb at about 0625utc-what was I catching? List said Africa and Carribean routes?

Its a fairly new weak signal digital mode used by hams called JT65

3452 = MWARA Central East Pacific, San Francisco Radio.
3455 = MWARA Caribbean, New York Radio.
Tokyo also uses 3455 but probably a bit early to hear them on that freq.

Thanks Bryan-appreciate that!

Thanks Brandon-that's ok I'll take New York and that explains why I didn't hear the aircrafts on 3452

Picking up 3455.0 khz weak but readable at 1145z.

I don't see MWARA docs showing Tokyo on 3455 but they are there. I'm also hearing NY Radio as well. Ironically, Tokyo is much louder than NY Radio. (Must be the day-night transition.)
