When I was at Purdue in the 70's we used Cat3 plain old 24ga telephone cable for hundreds of RS232 terminals on our Engineering Computer Network. We found, experimentally, that we could run 1Kft at 96

I'm not a "power" user. I'm a "low power" user. My previous machine was a 5W nominal 2015 Compulab Mintbox Mini, with a 4 core Athlon, at 1200 MHz. The Pi 400 is visibly quicker. I ran Debian Stretch

It actually works really well. I picked one up super early (before they sold out!) and have loved it ever since. I am still in the "testing" phase with my go-kit, but I do think it's going to replace

How is the performance of the Pi 400 with ham radio apps? It kind of looks like with a small HDMI touch screen it could work well for portable operation.

Good old time research data. Thanks for posting. Also, people today tend to forget that most communications now is serial. The SATA drive on your computer, serial, your WiFi connection, serial, USB 3.

RS232 physical properties The RS232 standard describes a communication method capable of communicating in different environments. This has had its impact on the maximum allowable voltages etc. on the

I have no connection to Sparkfun. (I found my Pi 400 kit at CanaKits.) 73

I was planning on using: https://github.com/scotthibbs/FDLog_Enhanced It has support for winter field day. -Heath

Troy Do a quick search on YouTube for "Fldigi field day" there's a couple of videos which may help if needed. 73 Glen

Hi Troy I'm not saying it's the best, but Fldigi may be worth checking out if using data modes. I noticed in the Fldigi configuration there's options to setup a multi-op Field Day logging Server/Clien

What’s the best Pi logging SW to use for Winter Field Day? Thinking about doing Pi only ...

It's TERRIBLE advice to other users to "never ever" patch your computers. If they are connected to a network that can reach the Internet, you're putting your system at risk as there are just too many

Really? As the linux developers find flaws in their code they put out newer versions. There are thousands of files and hundreds of packages and just a correction to one of the files in a package and i

I'm pretty sure the list will tell you. 73 https://duckduckgo.com/?q=sudo+apt+update&ia=qa

Then Name the security updates.

Updates fix security issues that are discovered. Bad advice to never do updates

Once your Pi is working never ever do an UPDATE, it makes no sense unless there is an absolute requirement by the developer of the application software. Create a backup image of your SD card once you

Good day, I bit the bullet and started with a new image on my Raspberry PI and loaded all new software (a lot of time). Still don't know why or where the problem was, but I'm up and running. Thank you

If you're needs are simpler and your devices identify themselves uniquely (not always a for-sure thing), you can use the "by-id" naming system already available on your system. For example on my machi
