263.925 CONUS: B-52 activity in clear voice!!! Skull 01, Red River, Mojo – passing status updates, tasking details and coordinating weapons de-confliction. Such a rare treat to catch this activity coming across UHF SATCOM in 2023 🙂


266.750 Águila

Radio testing from Águila attempting comms with Puma on #satcom 266.750 MHz. I think these might be Colombian military units.

265.250 King 69

265.250 CONUS: King 69 calling Tattoo Ops (sound like) on UHF satcom.


The past few days I have logged an accented station testing voice and DTMF tones on 252.150 and 251.850 MHz. Here is a brief recording. The operator sounds like he is identifying as “November Alpha 12345” along with some Brazilian stations mixed in – unknown if related.

Same individual was also noted using voice inversion on 251.850 MHz. Here is a recording of the voice inversion, along with the recovered audio.

Here is the scrambled traffic noted on 251.850 MHz.

Recovered audio from the transmission above. Definitely sounds like the same guy as 252.150 MHz.
