sigh I really need to come up with a reliable and inexpensive way to power cycle some equipment remotely.

My #raspberryPi is up and running but the two #SDR software defined radios aren't responding even after rebooting the computer. The computer was involuntarily power cycled twice yesterday when the power went out and when the backup generator transferred the house back to the grid after grid power was restored.

Or maybe the SDRs need to be reseated in their USB ports? 🤔

How to make an antenna to receive weather images from NOAA satellites? You can build one from a piece of wire in under 10 minutes.

Video is in Polish, but everything should be understandable without words :)

just giving #sdrangel a try...and wow. So many things! it even has ADS-B and AIS decoding built in. How is this software not more known about?

I have some beginner questions about SDRs:

1. Do you need to connect an SDR to a computer?

2. Do you need special software on a computer to access the SDR? Or are they all web-based these days?

I'm looking at possibly getting this:

Going for an upgrade on my SDR situation...I currently just have one of the bare cheapest $20 crappy ones that now has a faulty connector (It was using MCX for goodness sake!)

I'm thinking of going for a Nooelec one. Does anybody have any recommendations? preferably below $100AU

SatDump
A generic satellite data processing software.

Decode various satellites with SatDump using your Android device and compatible SDR. Receive #NOAA APT & #DSB, #LRPT, #HRPT, and other satellites, including geostationary ones like #GOES, GK-2A, on-the-go.
A good use case is receiving 137Mhz weather satellites conveniently.

Supported SDRs : #RTL-SDR, #Airspy, Airspy HF, #MiriSDR, LimeSDR Mini

If you are an IT professional, cybersecurity specialist or amateur radio operator in Canada - you might consider signing this petition and contacting your MP - banning a specific manufacturer/model of an SDR (software-defined-radio) is sheer lunacy and not going to stop anyone from stealing cars...

Entering hour 12 of being nerd-sniped by #WiFi throughput failures

I have, so far:

• Manually set the house's 5 ESP32-based heat pump controllers to their lowest transmission power

• Adjusted the AP’s 2.4GHz radio to use less power

• Created a dedicated SSID for streaming clients at exclusively 5GHz

• Removed short-range extender in the basement

Overall performance is much improved, but I still get an intermittent collapse in throughput. Going to have to pull out the #SDR next

The Canadian government is proposing banning software defined radios. I can only presume because they don't understand how anything works.

Fun in the sun today playing with this RFM69 radio shield from Adafruit. Vert900 antenna, not the best fit, but seeing nice reception over a distance, even non-LoS. Will test LoS with simple wire antenna.

CircuitPython has come along way, making prototyping easy. As a whole, a great platform for off grid sensor networks and low baud comms.
