HERMES H6 received in Texas EM12jw RX 1548Z 3April25
Good signal despite low pass.
Good hunting all

By the way it seems that, almost in defiance of the Shannonâs theorem, high SNR HERMES beacons can also be decoded from 48kHz ogg filesâŠ
Iâve tried this flow on observation 11343693 and the one from @geoscan, getting 2 and 3 good beacons respectively

Hi Felix,
Appreciate your candid response. Since Hyrda-W is using the amateur bands I for one would like to see the team share more information (and a parser) on the hex strings being transmitted. For example, an updated version of the kissgenesis.exe parser.
TU es 73,

Hi Bob,
No problem with that. Telemetry is the same as the HADES ones. They just include another packet for the experiments.

It is puzzling why with HYDRA-W it is more difficult to get decent TLE set.
@ea4gqs are they different in size or shape and therefore more sensitive to drag, or do we have the same LO issue as with HADES-x and that influences the selected data points?

Hi,
The hardware for HADES-R, HADES-ICM, HYDRA-T and HYDRA-W is the same. The only difference is in the payload they carry, but this is a minor one (just some grams of difference).
They payload aboard HYDRA-T and HYDRA-W transmit only a few seconds each time, so they donât have TX drift.
HADES-R and HADES-ICM carry the same experiment that transmits a lot of time, and here it is where we have the problem of TX frequency not being corrected by temperature while the transmitter is on.

Good day!
Since the objects tracked as likely Hermes-H* sats are still fairly close together, Iâm not clear what I might be decoding sometimes. I recall that my original âH2â decode was confirmed by the Team based on the first two bytes.
Is this frame received today (5-Apr) with â2d F7â as the first two bytes perhaps from Hermes-H6?
Thanks!

Hi @K4KDR,
yes this is HERMES H6, which is reguarly transmitting his beacon
We are still looking for H2 (2d 47), so if you see himâŠ
Thanks a lot!

Scott,
Recent results from em12jw and the timing of frames being received indicate itâs Hermes H6, despite H1 (AJ) and H2 (AK) passing over in succession.
Despite multiple attempts, I have never seen H1 or H2 active.
Hereâs the beginning of some decoded hex
0000: 2d f7 0a 0a 18 00 08 14 d9 23 00 69 20 03 19 00

GitHub with the source code for the decoder updated with HYDRA-T and HYDRA-W.
Andy is already aware, so a new DLL version for SoundModem will hopefully be available soon.

I confirm with many receptions in the Network. Also to mention that the TLE used right now is still very good for HERMES H6.

Please take the binary again. Andy saw an error in one of the packets sizes and I had to recompile it.
Last version is 1.11

Yes, this is the ID of HERMES H6.
As Francesco previously mentioned, you should convert the first two bytes in binary and take a subset of the bits:
2DF7 = 0010110111110111
bytes [2:11] = 1011011111 = decimal 735, which is HERMES H6 ID.
The IDs of the HERMES satellites is as follows:
- H1 1011010010 722
- H2 1011010100 724
- H3 1011010101 725
- H4 1011010111 727
- H5 1011011000 728
- H6 1011011111 735
We confirm that H6 is alive and well, while we are still looking for H1 and H2.
The release of the last three HERMES satellites (H5, H4 and H3) is foreseen for next week. We will provide you with updates closer to the release.
Cheers
Riccardo on behalf of the HERMES team
