This #sdr looks very interesting. Depending on the firmware you load onto its SD-card it emulates a #usrp or a #plutosdr and has an input for a 10 MHz reference frequency.
Bonus: it's open hardware. #libresdr #amateurradio #softwaredefinedradio

Finalizing the "Wall of SDR" ...

P25 in to Trunk Recorder

Multiple SDR into Kismet Wireless for 315/433/915/1090 and also a BT TIC for BTLE monitoring

Multiple SDR into SDR++ Server for local Amateur Radio Repeaters monitoring

Dedicated line to another machine for just specific testing.

And then finally documented.

I no longer have a transmitter to broadcast on as ZL4CDM, but having just been reminded of #SoftwareDefinedRadio ( #SDR ) I can surf the airwaves for all sorts of excellent audio snippets and textures of #radio to use in making #ElectronicMusic - could go great in making #BonkWave http://websdr.org/

HF Signal Enhancer for SDR: A Hands-On Build by Steve Allen (KZ4TN)

Satellite Signals:

Look for weather satellite signals by tuning to 137.500 MHz, using an external antenna and a decoding program like WxtoImg.

You can receive your own weather pictures from NOAA satellites.

Lincoln Experimental Sat 1 (LES-1) is another zombie asset in #Space.

This sat went quiet in 1967 before returning to life in 2012. Its time in service would help pioneer the use of the SHF band (7-8GHZ) for space communication.

Find it on 236.997mhz using SDR

You go on vacation but your interest in threat models and curiosity of such means you’re still gonna do hackery things.

Here we have two RasPi 5, 1 with 2 WiFi adapters another with 2 SDR devices…

A scan of the frequencies and the WiFi / LAN network tells you your rental has cameras.

So you continue to learn. On vacation. And make sure the cameras are legitimate.

This kit is a BagBuilds @bag.builds system from https://bagbuilds.com — it’s a great work up of available space and portability.

2 RasPi5, 1 GLI-net AP/Router, 2 Alfa AXML WiFi Adapters 3 Anker Batteries, BTLE sniffer, CatSniffer BTLE reader.

Kismet wireless deployed for a single GUI and reference point for devices in the Radio Frequency space.

This Android App helps to change your Android device into a dual channel AIS receiver that can be used to pick up AIS signals from nearby vessels, even if offline.

#Git repo of the day: This guy made an Arduino-based SDR https://github.com/K7MDL2/KEITHSDR #sdr #softwaredefinedradio

Some learning.
Some failure.
Some broken stuff.
Reworked some stuff.
Signals are still jacked.
Gonna need to rethink.
