Yet another 5 MHz aeronautical band pirate/peskie/who knows logging. This time its 5540 kHz (compare to previous logs for 5510 kHz USB and 5534 kHz USB). Googled 5540 kHz and 5540 USB and found nothing but information on shortwave broadcasters who use (or have used) 5540 kHz. Nothing about aircraft or military users of this frequency.
The 136th edition of the Spooks Newsletter NSNL 136 lists the frequency 5540 kHz as being used by station S30.
Peskie-like chatter in Portuguese with some sort of faint data signal underneath the voice traffic. Very long winded transmissions (also typical for peskies) with very little to no radio discipline, which leads me to believe that its not aircraft stations using a different language or military/government/diplomatic traffic.
