Thanks for pointing this out.
That’s a really strange behaviour.
Those additional packets are/were not displayed because the query of the dashboard’s panel says ‘show me packets where the source callsign is not JS1YPT’.
I’ve changed the query to also display those packets and the result is this:
The red marked text is not displayed because it was sent at the same second from and to the same callsigns. In this case Grafana only displays the last packet (here: ‘h’).
If it’s ok for you all, I’ll keep the usual query which is not displaying packets from JS1YPT to keep the panel clear.
Anyway, I don’t understand the sense of this behaviour and why ‘h’.
