Audio Sample |
Enigma designation XPB is a custom 16-tone MFSKMultiple Frequency Shift-Keying mode which is believed to be used by Russian intelligence.
The signal occupies about 2.8 kHzKiloHertz (kHz) 10^3 Hz of bandwidth, but the first tone is about 500 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). away from the designated transmission frequency, making the total bandwidth about 3.3 kHzKiloHertz (kHz) 10^3 Hz.
A 13-tone variant [1] and slower transfer rate modes [2][3] exist but it's not known if they use the same signal format or are used for the same purpose.
Frequencies[edit]
XPB transmissions occur on numerous frequencies between 10 MHzMegaHertz (MHz) 10^6 Hz and 20.1 MHzMegaHertz (MHz) 10^6 Hz. Frequencies between 4.4 MHzMegaHertz (MHz) 10^6 Hz and 10 MHzMegaHertz (MHz) 10^6 Hz have also been used, but it's not known if they are used since 2022.
