Many thanks to SWLing Post contributor Richard Cuff, who shares an article from Seth Hettena’s Substack about the appearance of a new shortwave numbers station believed to be broadcasting in Farsi. Numbers stations–mysterious broadcasts that read sequences of numbers–have long been associated with intelligence agencies communicating with field operatives using unbreakable one-time pad encryption. According to the report, this new signal first appeared around the time of recent military strikes involving Iran and has been heard on 7910 kHz. One of our readers reported hearing it around 2:15 UTC recently.
If you capture a recording of this numbers station, please reach out as I would like to add it to the Shortwave Radio Audio Archive. Thank you!
Frequency has been reported to have changed to 7.842 Khz USB. Two more hours to confirm this. Times have not reportedly changed.
I was able to catch it here in Jacksonville, FL a couple of times before the bubble jammer showed up:

may allow to listen to that station
I tried this frequency using a remote SDR just after 0200 UTC but all I could hear was a “bubble jammer”
