We’ll explore: • How the MeshPocket compares to DIY Meshtastic builds • Real-world durability and usability • Built-in features like the big battery • Why this is a HUGE step forward for plug-and-play LoRa mesh radios” #mesh #meshtastic #hamradio #radio #amateurradio #lora #heltec #meshpocket #emcomm #diy

Meshatasitc Firmware Update: 🚨 🚨 🚨 Meshtastic Firmware 2.6.11.60ec05e Alpha Pre-release Caution In older firmware, generated public/private keys may have insufficient entropy, resulting in the possibility of key reuse across devices. This release delays key generation until the user sets a LoRa region, and also mixes in additional sources of randomness. Additionally, if one of the known key collisions are detected, the user is notified, and should regenerate keys as soon as possible. #mesh #meshtastic #firmware #radio #hamradio #amateurradio #lora #entropy

GhostNet Version 1.5 By s2underground “GhostNet is the overarching term for a collection of communications networks set up to allow users around the world to exchange information without relying on pre-established infrastructure. Far from being just an emergency plan, GhostNet is intended to ease the transition of radio technology into everyday life. Though radio networks cannot truly replace the internet, we hope that we can replace a substantial portion of a person’s daily information requirements, and promote a culture of off-grid information sharing.” #ghostnet #hamradio #amateurradio #radio #js8call #s2underground #emcomm #prepare #prepper
