Suspected US military stations Hammer 16 and Hammer 11 conducting radio checks on CONUS satcom 252.150. Their signals were super weak for me, but I could make out one of them reporting at checkpoint Budweiser. They seem to be able to hear each other just fine however.
Possible related traffic on 253.850 as well, which was referred to as channel 3.

I’ve been hearing quite a bit of Spanish language traffic on 258.650. These comms sound more formal in nature and appear to be using callsigns, therefore I don’t think these are typical run-of-the-mill satcom pirates. Activity has been noted on multiple days and on several other frequencies. 258.650 is where most of the comms have been noted, but I’ve logged some radio checks on other frequencies including 253.850, 261.775 and 262.225 (with occasional test counts both Spanish and American accented English).
