One unexpected encounter on a #ham #radio #trip today. Luckily its mommy didn’t show up. #wwff OKFF-3159 #pota CZ-0200 I was just testing #aprs and #meshcore coverage of a close hill before lunch. Sadly, it is still too low for UHF to reach anywhere suitable.

While we #geeks play with #meshcore , the industry and governments work on global emergency messaging (one to many alerts) using #etsi standardized #dab. See https://www.worlddab.org/dab/asa-emergency-warnings The czech state radio just announced a pilot too https://www.lupa.cz/aktuality/cesky-rozhlas-otestuje-novy-zpusob-varovani-obyvatel-technologii-zaplati-operator/ Any tips about battery efficient DAB+ portable radio with this capability? Ideally AA powered!

@perlman yes, there are lot of things that work just fine. And then few things that were missed. For example the link proof can be linked with the sender via the signature done using the publicly known destination identity key. Or the path discovery breadcrumbs. And the statistical analysis of interface traffic that can link the various identities together. Network privacy is simply hard.
