Seems hugged. Look forward to looking at it when the site is back up - I want this exact sort of thing.

Well, they are different tools for different situations. I found, for what I do, having a vector network analyzer was more useful that having a spectrum analyzer. Specifically, measuring the SWR of antennas and measuring the resonance freq

I narrowed it down to something around my next door neighbor's house. The issue was there was something broadcasting a signal that covered the same range that my car key fob did, so I couldn't lock/unlock my car unless I was

The TinySA is kind of like a tiny radio, just tuning through the channels and measuring how loud at each frequency. And it managed to leverage an exiting chip (designed for other purposes), which is how it got to be so cheap. This is a gre

What frequencies, how many channels of analog/digital, what bit depth, how much memory, etc? What is your actual application? And what do you mean "PC attached" here? What is your budget? I don't think you are going t

I wish I had it when I was having an RFI issue in my neighborhood. I ended up with my RTL-SDR hooked up to my mac with a homemade copper-on-tape-on-cardboard yagi, and I looked like I was a tinfoil hat away from being needing to be put awa

A real thing: https://en.wikipedia.org/wiki/Spread_spectrum Fun fact, the famous actress Hedy Lamarr actually was instrumental in inventing it!

It surprises me that military drones aren't using spread spectrum to make this harder.

That's cool - didn't know that about Android. Another cool tip is to use NanoVNASaver ( https://nanovna.com/?page_id=90 )

For sure - if you can afford them, get both. I was just surprised because I expected to use the SA a lot more when I got it. But I am mostly either testing filters are designing antennas, and the NA is the way to go.

Make sure to heed the maximum input and use an attenuator! These are very cool and fun, but I found myself using my NanoVNA a lot more than my TinySA https://nanovna.com/

This guy recently made a neat roll-up antenna for 2m using "faraday cloth" https://www.youtube.com/watch?v=X7K6DNLD9Wo

I got this - I loved the idea of it. But my younger kid was on the edge of the age for it and outgrew it quickly. So now a friend's kid is enjoying it.

The man could write, but... Maybe you just have to be in the right mood. Reminds me of this onion article: https://www.theonion.com/girlfriend-stops-reading-david-fost...

I know a lot of people that bought Infinite Jest but I think only one that finished it... The never-ending footnotes did amuse me though.

Are you talking trash about Garth Marenghi?!

My favorite thing about the book is that each section builds on things, but you don't have to go through the whole thing to get there. So, for example, if you did a lot of hardware in the past but never got around to writing a compile

I don't understand how "One Hundred Years of Solitude" or "Catch-22" are on here. Maybe you just have to be at the right place in your life, but I just plowed through those in college. I've never gotten around

I remember using some Java "napkin" look and feel years ago. Really great for getting the idea across that this really is a prototype and I didn't just finish all the work in 30 minutes.

Is that something you've done before? What is involved in doing that? Sounds interesting.

Do you know what version of the app you have? I've not been able to reproduce it yet on 1.0.91 (Following the steps as I saw at https://twitter.com/Tims_Pants/status/1730515134731182490 )

The entire instruction of Scheme in 6.001 was less than an hour. You only need a tiny bit and then you can focus on the concepts in the book rather than quirks of some programming language's syntax. I think that is a huge win. On wh

HackRF One is an option. There are a number of others. Legality varies by country/frequency/power level. Can also make a Raspberry Pi act as a transmitter ( https://github.com/F5OEO/rpitx ), which could hit t

I remember quite a few people annoyed that we weren't getting some more famous speakers, but I grew up listening to Car Talk and I was over the moon.
