27348 27.348 MHz ALE Soundings 10 JUN 2024
« on: June 10, 2024, 2150 UTC »
Around 2130 UTC I heard what sounded like a 2G ALE call between CB Channels 34 and 35.  I got my decoder set up and waited to see if it would happen again, and sure enough, there was a station OTT sounding every few minutes.

Thanks to the heads-up from rob about the post on UDX listing several other frequencies, I've been able to log several more soundings by OTT this afternoon.

Assuming the station is sounding on all the frequencies listed, and propagation only allows me to receive some of them, the timing of the logs suggest virtually constant sounding with little to no pause in between.

The channels appear to be centered on an 1800 Hz offset from the carrier frequency, as would be common with some NATO PSK waveforms.
