DATE (DD-MM-YYYY)
TYPE OF UPDATE
13-11-2011
Added a sample of an 8-tone 250 Bd MFSK waveform, that is currently being
tested via the Swisscom / Bern radio TX-site in Prangins.

Als added an audio sample of the closely related 166.7Bd 4-tone QPSK waveform showing the system
changing from standby condition to traffic state (sending test patterns).
27-10-2011
Added additional samples of the Iranian serial tone QPSK waveform running at 469 and 1875 Bd

Additionally added samples of the Japanese Navy 1500 Bd serial tone waveform (aka "XSL / The Slot Machine") 
16-10-2011
Added a sample of the MIL-STD 188-110B FSK waveform
running at a symbolrate of 1200 Bd
07-10-2011
Added a sample of a 4-tone 166.7 Bd QPSK waveform, that is currently being
tested via the Swisscom / Bern radio TX-site in Prangins.
03-10-2011
Added a sample of a narrow band (3 kHz BW) variable PRF (16 x 64 sweeps) ionospheric sounder
operating on spot frequencies from about 27 MHz down to about 4 MHz. This sounder may be related
to the Australian JORN network.

Also added an unidentified datalink system using a 2400 Bd QPSK serial tone waveform.
02-10-2011
Updated some info on the MFSK and OFDM waveforms used by the "Serdolik"
long range radio system seen on the Russian diplomatic HF network
01-05-2011
Added a sample of the modified WinDRM 51-tone OFDM waveform used by an unidentified
British MIL or government user (apparently a replacement for the 195.3 Bd 4FSK waveform)
30-04-2011
Added a sample of a 7-tone 200 Bd MFSK system
(any additional info regarding the manufacturer or user is highly appreciated)
24-04-2011
Added samples of the Cyprus based OTHR system transmitting from Akrotiri running trials
with a new 12.5 Hz waveform at 8 kHz bandwidth and 80 kHz bandwidth
16-01-2011
Added an improved audio sample of the 150 Bd FSK selcall system used in several Russian/CIS military radios. 
FFT screenshots were updated accordingly.

An additional audio sample of the Siemens CHP-200 system was uploaded, showing two stations linking with the
proprietary CHP-200 selcall mode and switching to non-hopping 250 Bd ARQ after about 20 seconds. 
09-01-2011
Added samples of a 100 Bd / 625 Hz FSK waveform used by Polish intelligence for one-way broadcasts via HF.
This is the digital counterpart of the analogue voice broadcasts that have been labeled as the E11, G11 and S11 family by the "Enigma 2000" group
06-01-2011
Added a sample of the Algerian Air Force Bell 103 compatible FSK modem running 75 Bd.
This FSK modem is probably embedded in one of the various encryption systems manufactured by Crypto AG (modified HC-535?).
