Both of us use different antennas (literally scrap), we use meshstatic with raspberries.
This will be of much help if you're looking to get started: https://meshtastic.org/docs/hardware/
Also 300km is indeed almost obstacle free, there's lots of villages and forests in between but one of the antenna is located on 12th floor of a building in a city. Coverage is not really the issue, even inside the city with all interference, we did manage to establish a proper connection within 3km, one antenna on 4th floor and the other one on the first floor with lots of tall buildings in between. (Worked much better than expected)
Mad fun project to get started with, highly recommended. Is it of much use? Not yet, not really. But we are planning on pumping up the power a little bit, add a few more nodes and hopefully we will be able to deploy a Lemmy or something and step by step we will create our own shitty "undernet".
Everyone agrees that killing protesters is wrong, no matter the number. The real issue isn’t just about how many deaths justify action, it’s about fairness. Why do some countries face outrage and others don’t?
Instead of arguing over numbers, maybe we should focus on how to hold all governments accountable without making things worse. (Which is just dreams, we can't really hold anyone accountable nowadays)
Violence from outside rarely fixes things, but ignoring injustice isn’t the answer either. The goal should be justice for all, not just the cases that fit our biases, and no country should unilaterally decide when or how to intervene in another’s affairs without facing serious scrutiny.
Ultimately, I don’t believe the US and Israel would intervene in Iran to protect protesters. It feels more like a pretext to install a regime that serves their own interests, more precisely, Israels interest. For "the great israel".
Also, never forget Holodomor, done by the zionist stalin in order to decimate a freedom movement at that time.
