Hai mai SENTITO un segnale #LoRa ? 😮

In this video, we do something curious: we listen to the LoRa signal and try to understand what's behind that peculiar modulation. Link aff.

If you're using Meshtastic, understanding these presets is essential for choosing the right balance between: 📡 range ⚡ speed 🔋 power consumption 👍 Like if you like these radio insights 💬 Tell me in the comments which presets you're using in your Meshtastic network Registered with (affiliate links): Webcam obsbot tiny 2 lite https://amzn.to/3ZX54cQ Insta360 Ace pro https://amzn.to/4ku85uU Insta360 Go ultra https://amzn.to/3ZoDLbb DJI mic mini https://amzn.to/4bGID2T Rode procaster https://amzn.to/46x7531 Davinci resolve studio https://amzn.to/4qtVtVV MacBook air M4 https://amzn.to/3Miz0wX ⸻ SUMMARY: 00:00 What does a LoRa / meshtastic signal sound like? 00:52 Let's see and hear the LoRa signal 01:23 How does LoRa modulation work? 02:15 Why use mediumfast? 04:20 Difference between the different meshtastic presets 05:45 Better to understand instead of just copying... #Meshtastic #LoRa #SDR #HamRadio #Radioamatori #MeshNetwork #WirelessTech #LoRaSignal #TechRadio #OffGridComms #LoRaEU
