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/

Ever wanted to (very illegally) flood the entire FM broadcast spectrum with Taylor Swift songs? Well, now you can!

Heads up, there are only two kinds of #nooelec #softwaredefinedradio : those with no bias-T, and those with a bias T that cannot be turned off. Fortunately, I got the former, and didn't accidentally release the magic smoke from any of my equipment, unfortunately I still need USB power to run my LNA

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.

Dealing with Drift:

Use a known stable broadcast like a time signal station (e.g., WWV at 2.5, 5, 10, 15, or 20 MHz) to calibrate your SDR's frequency accuracy.

Understanding the role the radio spectrum plays in modern cybersecurity is a huge part of learning about and securing RF-based devices.

@three_cube has a large array of training materials and resources to help with this.

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
