Bu RTL SDR Dongle ile ne anten sorunu yaşamıştım!

Sorunu hâlâ çözemedim.

Kullanmadığım için artık sorun olmuyor! ツ

En kötüsü de Kısa Dalga (SW) yayınlarını dinleyebilmek için odamın ortasına çaprazlama 5 metrelik Şerit Metreyi boğazımın hizasında asmak olmuştu!

Yerinden kurtulup boğazımı kesecek ve kan kaybından aptalca öleceğim endişesi ile o anteni kaldırmak zorunda kaldım!

Bir daha da bu SDR Dongle ile Kısa Dalga (SW) da iyi ses duyamadım!

TECSUN PL-330 minik Dünya Radyomu almadan önce şansımı bu SDR Dongle ile denemiştim.

Aslında şelâle ekranını çok severim.

Ayrıca aynı anda yakınlardaki birden fazla istasyonun yayınlarını görsel olarak takip edebilmek harika bir şey.

Fakat o RTL SDR Dongle ile ciddi anten sorunu yaşadım ve maalesef ona uygun güçlü bir anten bulamadım!

TECSUN PL-330 ile net çektiğim FM istasyonlarını bile düşük ve zor duyuyordum!

Taiwan’s train cyber incident is putting legacy wireless infrastructure under the spotlight.

Reports suggest replay attacks and low-cost SDR tools may have contributed to the disruption.

Unrelated to us, chrismoos has just released what looks like a rather comprehensive implementation of the CDMA2000 1x cellular system as open source. From a SDR PHY through RAN to CN. It includes the signaling plane, circuit swithced calls, messaging (SMSC) and packet (IP) data.
See https://1xbts.org/ and https://github.com/chrismoos/1xbts for more infromation. #cdma2000 #retronetworking #cellular #sdr

Sto preparando la candidatura per Maker Faire Rome di un progetto nato anche grazie al lavoro fatto su Drone Sky Check.

L’obiettivo è creare un nodo portatile di “air awareness” capace di ricevere:

ADS-B
Remote ID
OGN/FLARM
segnali RF legati ai droni

integrando tutto in una visualizzazione live 2D/3D.

Tantissime ore tra SDR, mappe, parsing, realtime e debug 😅 insieme agli amici di Drone Pilots Team

Создаем собственную базовую станцию при помощи SDR

В этой статье я хочу рассказать о том, как я запускал собственную базовую станцию мобильной связи (4G и 2G) при помощи относительно дешевого SDR-трансивера.

Передача данных по лазерному лучу (BPSK)

В этом тексте я попробовал осуществить передачу данных по лазерному лучу буквально на основе подручных материалов. В тексте представлены основные идеи и решения для передачи и приёма битового потока c помощью BPSK модуляции.

Some articles just leave me genuinely confused. Like this one:

https://www.rtl-sdr.com/student-arrested-in-taiwan-for-using-sdr-and-handheld-radios-to-halt-four-high-speed-trains-with-tetra-hack/

A student managed to send an emergency radio signal to the Taiwanese railway system, and as a result, the emergency brakes of the trains started to engage. They mention that there are seven (?) verification parameters, but what does that even mean? Did he simply do a replay attack, since the traffic was unencrypted? If there were secrets in place, why were they not rotated?

For now I have to assume that the radio communication was just not adequately secured, which happens more often than you might think. But if you have any information on the technical details of this incident, please let me know :)

I’ll cut to the chase: it’s a nice resolution upgrade from an Apple or LG 5k display. But that’s about it – in every other visual respect (brightness, contrast, etc) it’s basically the same. Though the built-in KVM is a nice addition.

Resolution

The extra resolution is significant – it is 38% more pixels – and welcome, but it’s not revolutionary. It feels like what should have just been […]

My solar inverter is sitting on the floor of the garage, disconnected.

Now would be a perfect time to get a baseline reading for how much RF noise there is in the neighbour before the new inverter is turned on.

What’s the best tool for this? RTL-SDR with Qube??? KiwiSDR but don’t refresh the browser window just take a screenshot
