Observation 11546350: ArcticSat-1 (61762)

Regarding Observation 11546350

well… I’m new with gr_satellites

I got this from this observation.
Is it correct?
Is it TLM?

Using the SPUTNIX Telemetry Viewer

question: I try to run your same command. but it gives me
Are you using a different version?

Could not open SatYAML file:
[Errno 2] No such file or directory: 'ARCTICSAT-1.yml'

I shared the ARCTICSAT-1.yml content in the previous post, create the file with the content shared.

This is my first time hearing of this software. Could you please give a little tutorial or briefing on how to use it or understand the interface?

Like all AGWPE client implementations you need a soundmodem that support this client server protocol. The soundmodem version from UZ7HO all support this option and is enabled by default.

Some steps:

Run the UZ7HO soundmodem for the specific satellite/mode and check settings → devices to see if the AWPE Server port is set and activated.

Now you can run the SPUTNIX Telemetry Viewer and click connect.

All audio received by the soudmodem and that is successfully decoded will be forwarded via the AGWPE link and converted to telemetry information.

Another quick check is via notblackmagic.com

Just copy the first 16 bytes (the first row)

a4 64 82 9c 8c 40 60 a4 a6 6e 68 a6 40 63 00 f0

(Destination Callsign - Source Callsign)

and paste it as shown in the screenshot below.
