Short answer; yes.
Long answer:
You can go to raspberrypi.com/software to find the imager program. That will allow you to use a Mac or Windows PC or Linux machine to install a raspberry pi OS onto an SD card. There are options for different versions and a lite or full version. There are also options for specialized versions of the OS for special purposes (stay away from these for now, those for non-ham projects).
If you need more guidance than that, please reach out directly to me off list and I will try to help you work through the steps. They are not hard but it can be confusing if you¡¯ve never done it before. A little help can go a long way.

I would start with a fresh SD card. You never know whether there are any specific setups that would otherwise create problems.?

Depends on use - if all you want is accurate time, the RTC may suffice, but it will drift over time, ?just like a desktop or laptop computer, which correct their RTC over the internet. If your RPi will frequently or permanently be connected to the internet a GPS receiver may not be needed.
Of course, if you want to know where you are (long/lat), you'll need a GPS receiver.

RPi 5s were hard to get our hands on for a while, so that may be part of the explanation, but there are reasons to choose an RPi 4 over an RPi 5:
Power consumption Heat generated Requirement to use Bookworm (latest version of Raspbian)
The benefits are:
Much better performance (processing speed) RTC on-board, add optional battery PCIe expansion (native NVMe SSD support)
For many ham radio applications, an RPi 4 is absolutely adequate, but in some cases it's worth overcoming the issues with an RPi 5 - for example, digital mode decoding (WSJT-X).
The other issue may be that the Ham Radio projects you're finding on line may simply have pre-dated the wide availability of the RPi 5.
Hope this helps,

Generally, the Raspberry Pi instruction for a RPi 4 will work the same on an RPi 5. The newer model might have a faster processor or more ram, but the OS should work just the same!
Best of luck?on your Raspberry Pi adventures!

Re: Pi Hardware Question - Solved!
Thank you, K7MHI and N0SR
?
I took your inputs and did a little more snooping around the internet and finally figured out a solution, but I don't what is going on.
?
Recap - With Pi 4 or 5, using either X-windows or Wayland, the Motorola Lapdock screen is skewed. ?The lower left corner is attached to the lower right corner. ?Trying to rotate the screen doesn't work, it just rotates in the same frame (lower left is attached to lower right of screen). ?This is at the Lapdock's 1366 x 768 resolution.
?
Solution - decrease the resolution. ?Selecting the 720x576 resolution (the next lowest choice available) and the screen is now correct. ?This resolution is too low to be useful but the only one available. ?I did find that I can add in other screen resolutions using the xrandr commands (never knew about this before, thanks for pointing it out). ?
Note: ?All of below is using pi set to use x-window.
Using the Add Programs menu item on the Pi, I added in four libraries from XCVT.
Executing the commands
cvt 1280 768 (results in getting the parameters for a screen resolution of 1280x768. ?Copy everything after 'modeline:' .................)
?
xrandr --newmode (paste in the line from the cvt result)
xrandr --addmode HDMI-1 ?--mode 1280x768_60.00 ? (Where HDMI-1 is the name of your screen and the mode name comes from the results of the cvt command)
xrandr --output HDMI-1 --mode 1280x768_60.00 ?(now the screen will go blank, then come back at this new resolution and oriented correctly.)
?
Only drawback is this change is not permanent. ?You have to run it each time the pi is booted up. ?This can be fixed by making a shell command containing the three xrandr lines, which can be executed manually or automatically during boot up. ?It is transportable across machines. ?
The 1280x768 resolution was selected because it was the next lowest standard resolution that I found.
The link here, describes this process in detail: ??
?
I am guessing that the higher 1366x768 resolution has a conflict with the hardware in the Pi 4 and 5's. ?Anyway, I got it working and learned some new stuff about linux.
?

Re: 73 Linuxnot ready for mint 22?
I didn't look at the release date -- but if it was that recent no wonder I had the problems I did!!!
?
I'll give 21 a try.

Re: 73 Linuxnot ready for mint 22?
Didn't Mint 22 come out yesterday? You're probably one of the first to try it. I did an install of 21 last month and the only problem I had was with a dependency issue around the version of WSJT-X it was calling which I was able to correct by removing and installing a different version if memory serves.
I picked up another Wo-We computer, the Linux version, and have been playing around with it.? (Have had one WO-WE working with mint for over a year just fine-- except for the re-boot issue.? Basically the KM4ACK "version".)
?
Couple of observations and questions.
?
-
The computer came with Ubuntu Linux loaded -- took me a while to figure out how to log in since I couldn't find what the release used as a password -- internet searching gave me nothing directly but found a ¡°back-door¡± that worked by forcing Linux in to recovery mode and changing the root password. If you need this, the how-to is on the web.
-
Changing the boot options to boot from the USB device didn't work the first couple of times, but turning off the ¡°fast boot¡± (or whatever it is called) seem to work. Not sure why will have to look at this some more.
-
Downloaded mint Linux and took the most recent version, 22. Loaded that and it worked fine.
-
When I tried to run 73 Linux on the machine a lot of things didn't build, e.g. Corky, fldig, flrig. There were error messages, but for this exercise I didn't spend any time on them.
?
So I am assuming that 73 Linux hasn't been changed to work on 22. That's fine I was just messing around.
?
Questions:
?
1, Which version of Mint is working well with 73 Linux. I do want to get this computer set up to work with my radios.
?
2. Is there a working? version of 73 Linux and Mint for WO-WE that does not have the problem with the system going crazy when booting up, or am I going to continue deal with this when I do load a working Mint?
?
BTW. I haven't upgraded the hardware on this box yet, e.g., memory or disk so maybe things will change when I do.

Re: Conky not displaying Gridsquare
#conky
Having same issue, but only with one set-up, a Pi4.? I have other Pi's and my Evolve Iii running conky and the gridsquare displays just fine.? My problem Pi4's GPS displays satellite data and gives me lat/long, but no gridsquare.? I followed your advice below by running get-grid and grid from the terminal, but for both I get "cannot load such file -- gpsd_client (LoadError)".? I checked and have latest version of gpsd-clients installed.? Also running Ruby 3.1.2p20.? New to Linux but this problem has given me a crash course.? What can I do to fix this?
