HADES-L

HADES-L Test GRC on Windows


[Common features of HADES-SA and HADES-L]

HADES-L is not AX.25, It uses a proprietary "GENESIS format 800 bps FSK".
ALooking at the source code for the HADES-L decoder released by AMSAT-EA,
it is clear that HADES-L also follows the same specifications mentioned
above. Furthermore, HADES-L's main.c directly includes genesis_crc.h and
genesis_scrambler.h. In other words, this is not merely a similarity in
name, it confirms that the actual HADES-L decoder employs the GENESIS method.
HADES-L also employs the same GENESIS series data demodulation and decoding
formats as HADES-SA.

[HADES-SA ＋ Soundmodem]

In 60923hda.wav, the received HADES-SA frames are displayed continuously
within UZ7HO's Soundmodem_for_HADES_SA_SpinnyONE.zip (v0.05b). The console window
of the bundled KISSGENESIS.exe which interfaces with Soundmodem displays items such
as packet type 13 and packet type 11 (CODEC2 voice) from the SpinnyONE HADES-SA.
This 60923hda.wav is an actual HADES-SA audio file that can be successfully decoded
as GENESIS 800-baud FSK.
