Was watching 11175 kHz USB on the waterfall, and noticed SSB traffic 5 kHz up on 11180 kHz USB (which is also a USAF HF-GCS frequency, alternate to 11175 kHz USB). Hearing casual Italian language traffic on 11180 kHz USB. One station is considerably stronger than the other, but doesn't sound like aircraft comms to me. Could be wrong (it should be aircraft, military aircraft communications, considering the frequency in question is in the aeronautical off-route band).
Either pescadores or Italian military traffic? I don't speak Italian but this sure is an interesting frequency either way. 11175 kHz USB is active at the same time as well.
