More on Raspberry Pi substitutes #rpi

Russ, KC7MM
 

I've made more progress on identifying economical substitutes for the Raspberry Pi for use in Amateur Radio, adding another Chromebook and an Intel NUC to the list. The results thus far are now posted on my Web site. There's more work to be done, and I'll update the post to reflect new results.

My guide has been updated and refined based on some excellent feedback that David Ranch sent me off list: https://github.com/masenf/kf7hvm-com/commit/a48a3fac0d9d9842f5d0882c8de6245220e3cd6b

Thanks for reading through and taking the time to send your feedback!

Great write up Masen! Thank you for set up for the PI and for participating in the Linux User Net each week!


Raspberry Pi OS 2022-04-06 Setup Tips for Digital Modes #rpi

Masen KF7HVM
 

I wrote up some helpful setup steps for configuring the latest Raspbery Pi OS with xrdp, direwolf, YAAC, FLrig, and pat: https://www.kf7hvm.com/info/packet/pi4-setup/

There are at least 3 things that were news to me on this version (and fixed in my guide):
  * xrdp was just broken out of the box - black screen
  * fldigi GPIO PTT support is broken
  * pi user no longer exists by default, a new bootstrap file, `userconf` is required for headless setup

Thanks for the great net,

A note about "Look Inside Linux"

Russ, KC7MM
 

I just want to mention that I'm working on more installments of the "Look Inside Linux" series that I've been presenting on the Linux User Net. The only difference is that the presentations won't be made weekly, as they had been until recently. Instead, they'll pop up from time to time as I work through my list of topics at a more leisurely pace. Also, a reminder that my notes for all of them are available on my Web site.

Hacking WinAPRS

ODROID M-1 Raspberry Pi Alternative?

Masen KF7HVM
 

I shared this last week on the net, but here's the actual link: https://www.hardkernel.com/shop/odroid-m1-with-8gbyte-ram/

This ARM64 (rockchip) board has native SATA, which you would expect to have much faster IO than you would get with MicroSD or even eMMC.

$90 for 8GB of RAM, and appears to be in stock.

Re: Lenovo ThinkCentre M625q on Ebay for $50 -- Raspberry Pi alternative #rpi

Yup. When I was researching small, portable Linux laptops awhile back, I ran into that a lot. It runs Linux in the big print, but it's a custom build in the small print. Yikes! Snakes everywhere!! :)

Re: Linux logging programs besides CQRLOG

Bob Recny
 

Thanks Roy!
I'll give it a whirl once I set up my main laptop for dual boot. (It's still on Win11.)
I also found this one: https://www.magicbug.co.uk/cloudlog/
Looks interesting, and it looks like it's free if you self-host. I don't think rig control is there yet, though.
Lots of Linux Radio projects queuing up ;-)

Re: Linux logging programs besides CQRLOG

Hi Bob,

I use CQRLOG as to some extent, and I really like it. The only reason I don't use it as much anymore is because I wrote my own logging/automation app. But mapping features are pretty lacking. For general station logging, though, I would recommend it.

While that looks to be decent, I was curious if there is anything closer to Log4OMNG on Windows or RumLogNG on Mac. I really like the map options. While FT8 may seem like a bunch of unnamed contacts, it's a really cool geography lesson to see each station location that I work.

Linux logging programs besides CQRLOG

Watch out for debian/ubuntu package `pat` 0.12.1-1

Masen KF7HVM
 

I posted this message over on "pat users", but I thought it might be relevant to users here as well: https://groups.google.com/g/pat-users/c/AJmJ9_OYlAc/m/9XmixCWoAgAJ

The short of it is the debian maintainer had to rename the pat binary to "pat-winlink", and as far as I can tell, the distro package doesn't support regular ax25 packet and thus is unusable to me.

You can disable automatic updates in ubuntu... but maybe it's not the best idea, so I just "hold" packages that I don't want getting swapped out from under me:

apt-mark hold pat

Linux, inside a radio (Xiegu X6100)

Chris, WA4NDR
 

Hello all,

I saw this post on YouTube from a channel called "Temporarily Offline Ham Radio".
These guys have been playing around with Xiegu's newest HF radio, the X6100, and found that it runs Linux inside.
They have been trying to boot their own different flavors of Linux on it in an attempt to get a GUI and eventually software like WSJT-X up and running.
For the longest time they had been running into various issues like the screen being displayed sideways, or certain features not working properly.

Well, it looks like someone cracked the code. A user on Github by the name of Links2004 managed to get Armbian to boot up on the X6100.
Not only that, but they managed to get WSJT-X up and running, allowing them to run FT8 directly on the radio.

Check it out here:

The fact that these guys were able to get a Linux GUI and more running inside of a radio really goes to show just how flexible Linux can be.

Good news for Washington County! You can try to get on the AREDN WVMN mesh now on the new K7RPT South Saddle Sector 120 device.
Check out https://willamettevalleymesh.net/meshmap/ for the map.

Re: Installing Linux on a Chromebook

Bob Finch
 

Hey Russ;

TNXS fer asking OM !

Well I have TWO C710's:

- one of which is dedicated to packaging and (some of my) programming work. This one has an archlinux install that is at least 8 years old, and it is updated at least once a week to the latest software available for the installed packages. (This one was not converted with mrchromebook.tech, as it was converted in 2013.)

- the other C710 was recently, using Manjaro, converted using mrchromebook.tech 's scripting. It is used for day to day work and compliance (new user, clean platform) testing of some of my programming.

I truly enjoy the full keyboard that the earlier chromebooks have, including the C710's.

I also have a C720, which is dated late 2013, and which has the newer style keyboards. (Sigh...) It is used as a ham radio testing platform atm.

** Interestingly my daily "desktop" computer is a rpi4-8gB also running Manjaro aarch64 (native 64 bit-arm-architecture complied code.) Manjaro was the very first to offer up a FULL Linux-OS in 64-bit-arm. Works f.b. for HD youtube, email, and so forth. I have a larger monitor, regular keyboard and mouse, speakers, etc. hooked up so it is pleasurable to use. I did this install about 18-24 months ago, it came right up and it is updated when it tells me to....hi hi.)

(I also have another rpi4 running in the background, doing stupid little tasks in the "shack/office". It is using raspian and was a pain to set-up and get running right the first time...hi hi. I did that about a year ago, and things may/could be better now with the conversion of raspian to 64bit.)

Hardware support for stuff like the rpi4's and the Chromebooks is excellent using Manjaro and/or archlinux. Setup and hardware support is auto-magical, as in it unlike the "other stuff" (other linuxes), as it just seems to install and run. (YES, I am biased, but that is logical considering my background.)

Bob, the firmware from mrchromebox.tech is what GalliumOS relies on, and is what I installed. It does indeed allow for any Linux distro to be installed. I went with GalliumOS to see how it works. I also had read of people having trouble with other distros' lack of support for things such as touchpads and sound, so I wanted to take advantage of whatever Chromebook optimizations Gallium might have. I'm pleased with what I've seen so far.

Interesting to hear you have three conversions in the shack. What do you use them for?

Re: Installing Linux on a Chromebook

Russ, KC7MM
 

Yes, Crouton is an option, Kevin. I had looked at it, but decided I wanted to remove the Google connection, and also to devote all the machine's limited resources to Linux.

Thanks for mentioning that the SSD on your Toshiba is soldered on -- that's useful information for anyone looking to buy a Chromebook to convert. Of course, it doesn't matter if they're not planning to replace it.
