WCH SD22 - Node Details

This radio now reports as !03441533 WCH SD22. Firmware 2.8 derives the node number from the node's public key, so since the upgrade (new id first seen 2026-09-19) its packets, position and telemetry are recorded under the new id. This page no longer updates and the map hides its old marker. (linked by public key)
