SDR# VS Insight Maker

As far as assembling an SDR from discrete parts, you can check out the MCHF kit or Asher Farhan's sbitx. Great radios, but nothing like the value prop of the RTL-SDR. If you're just looking for a cheap radio to listen with, I'd recommend Airspy. Source: 10 months ago

But look, rtl_sdrs are not a great choice for HF. I would recommend looking at Airspy or SDRPlay if you want to receive HF. Source: over 1 year ago

Then there are non-RTL-SDR devices, like devices from AirSpy, some of which use RTL receivers, and some that don't, but present themselves to the computer as a unique device that requires separate drivers and software. Source: over 1 year ago

Minor plug. Airspy had some very high quality SDR receivers and they do a Black Friday sale every year. https://airspy.com/ Not sure when it ends but if you’ve been running Annie doing your toes into SDR these are good products. I’ve got both the R2 and HF+ products and enjoy them both. RTL’s can’t be beat for price alone but if you’re early distracted by hardware limitations they can be a challenge lol. - Source: Hacker News / over 2 years ago

I'm looking into free to use online simulation and collaboration software such as https://insightmaker.com/ and will start digging into it. Source: over 1 year ago

I created a fairly popular system dynamics modeling applications back when I was a grad student [0]. When using modeling tools like system dynamics, it's useful to keep in mind George Box's quote that "All models are wrong, but some are useful". When using a modeling tool to describe any form of social system you're creating an imperfect copy of it. This imperfect copy embeds what the modeler (rightly or wrongly)... - Source: Hacker News / over 1 year ago

Some other commenters here seem to think this article is (or should have been?) an introduction to systems thinking, or an argument for using it. The article is explicitly framed as some advice, based in experience, on avoiding common pitfalls with using explicit models in systems thinking. As such I think it is a nice read. It is also full of links to other interesting work by the author, not least of which is a... - Source: Hacker News / over 2 years ago
