The signal you are receiving is ALE (Automatic Link Establishment). The stations perform regular "soundings" on pre-assigned net frequencies in order to maintain a link quality analysis and determine the best operating HF frequency.

[00:00:00][FRQ 10345000][SND][               ][TWS][XSS            ][AL0] BER 24 SN 06
[00:00:00][FRQ 10345000][SND][               ][TWS][XSS            ][AL0] BER 21 SN 06
[00:00:00][FRQ 10345000][SND][               ][TWS][XSS            ][AL0] BER 16 SN 05


I have 10345.0 kHz registered to the Saudi Arabian Air Force Airfields Net but the call sign in the transmission is XSS which is the UK Defence HF Communications System. XSS, Forest Moor, is net control.

Note: Be nice to include the location you are receiving from.

Thanks for the location. That lines up well with XSS in the UK.

If you go to your "Account Profile" and select "Modify -> Forum Profile" you can enter your Location: there and any other information you want to be automatically displayed.

Welcome to the HFU and happy monitoring.
