Feel as though it&#x27;s worth mentioning here that using LTE Direct (<a href="https:&#x2F;&#x2F;www.qualcomm.com&#x2F;news&#x2F;onq&#x2F;2014&#x2F;11&#x2F;true-or-false-getting-direct-about-lte-direct" rel="nofollow">https:&#x2F;&#x2F;www.qualcomm.com&#x2F;news&#x2F;onq&#x2F;2014&#x2F;11&#x2F;true-or-false-gett...</a>) every phone could become a node in a long-range mesh network in an emergency. This approach takes advantage of both the strong radios in smartphones and the available node density provided by smartphone ubiquity.<p>The tech has already been proven—carriers just need to be mandated to add it because there&#x27;s no business reason to do so.

Honestly very disappointed that phone makers haven&#x27;t implemented radio in phones.

Interesting that they are using such a high frequency, I hope it serves them well. Should be reasonably free of long range interference.<p>But surprised that there are no 3.5MHz&#x2F;7MHz&#x2F;14MHz band frequencies in use for regional communications. Or they have not been declared yet for emcom use like with Nepal and Puerto Rico.

Once Turkiye&#x27;s best mobile network (Turkcell) introduced a drone cell tower (never has been used, I think because of battery issues?):<p><a href="https:&#x2F;&#x2F;www.telecomsinfrastructure.com&#x2F;2019&#x2F;07&#x2F;dronecell-turkcell-flying-base-station.html" rel="nofollow">https:&#x2F;&#x2F;www.telecomsinfrastructure.com&#x2F;2019&#x2F;07&#x2F;dronecell-tur...</a>

At the moment, I am not getting any traffic on this channel. I am in central Italy, not far away, from a radio perspective, to Turkey.

I&#x27;ve made this comment here on HN before, but this reminds me of a tweet that I saw last year in which someone said:<p><i>&quot;In breaking news moments like this, there should be a type of podcast you can listen to in real time, easily accessible for free.&quot;</i><p>To which someone replied: &quot;Radio. You&#x27;re thinking of radio.&quot;<p><a href="https:&#x2F;&#x2F;twitter.com&#x2F;jodyavirgan&#x2F;status&#x2F;1234998790139940865" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;jodyavirgan&#x2F;status&#x2F;1234998790139940865</a><p>It&#x27;s always nice to see this technology (and the community) lean in to support disasters like this.

How can I stream this?<p>Is it 28540KH?<p>From this site in Washington there&#x27;s nothing - <a href="http:&#x2F;&#x2F;na5b.com:8901&#x2F;" rel="nofollow">http:&#x2F;&#x2F;na5b.com:8901&#x2F;</a><p>A site in France seemed to have nothing.<p>How close does it have to be?<p>[edit] I will say WebSDR is fucking cool. Closest I can see is <a href="http:&#x2F;&#x2F;94.137.189.166:8901&#x2F;" rel="nofollow">http:&#x2F;&#x2F;94.137.189.166:8901&#x2F;</a> Tbilisi - Georgia 500 miles away but doesn&#x27;t have anything, unless I&#x27;m using this wrong.

The radio thing is interesting but this is the first I am hearing of this quake, so here is a Reuters article with basic facts. Thousands of lives lost. A serious tragedy.<p><a href="https:&#x2F;&#x2F;www.reuters.com&#x2F;world&#x2F;middle-east&#x2F;major-earthquake-strikes-turkey-syria-about-200-dead-many-trapped-2023-02-06&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.reuters.com&#x2F;world&#x2F;middle-east&#x2F;major-earthquake-s...</a>
