Talk:Unknown 20p973 data burst with intro tone
From Signal Identification Wiki
It seems that this signal might be High_Frequency_Data_and_Voice_Link_(HFDVL). I noticed that only after creating this page. Confirmations would be appreciated. Emcbro (talk) 05:33, 1 October 2024 (NZDT)
Possibly identified: I think this may be "RFSM", derivative of MIL-STD-188-110. Used for example by Bulgarian diplomatic services. Very similar sample was found, see:
