Deep Dive Topic - Ubuntu 26.04 LTS Resolute Raccoon

• Canonical released Ubuntu 26.04 LTS “Resolute Raccoon” on April 23, 2026, marking a significant modernization of the distribution with GNOME 50 and the Linux kernel 7.0. This LTS version offers five years of standard support until April 2031, extending to ten years with Ubuntu Pro.
  • Key updates include:
    • Wayland-Only Desktop: The GNOME session now runs exclusively on Wayland, dropping Xorg support, though X11 applications remain functional via XWayland.
    • Enhanced Security: The release introduces TPM-backed full-disk encryption, post-quantum cryptography support in OpenSSL, and the Security Center app for desktop management.
    • New Default Applications: Canonical replaced legacy tools with modern GTK4/libadwaita apps, including Ptyxis (terminal), Papers (PDF), Loupe (images), Showtime (video), and Resources (system monitor).
    • Developer & Server Improvements: The toolchain features GCC 15.2 and Python 3.14, while server editions support Intel TDX and AMD SEV-SNP confidential computing.
    • Hardware Requirements: The recommended minimum RAM has increased to 6 GB to accommodate the modern desktop environment.

OHB ver 4.23

 I have been sitting back and watching the many Hamclock projects evolve. What I was looking for was a project that, when finished, resembled Elwood's Hamclock. I am happy to report that I have settled on using OHB or Open Hamclock Backend. This has a very polished look and looks and operates, in my humble opinion, the closest to Elwood's Hamclock. It is a group effort and has progressed at a smooth pace. There is an OHB web page that offers support and status updates. I operate HamClock on my Pi4B, and if you operate Elwood's HamClock on a Pi, below is the process you go through to move from Elwood's version 4.22 HamClock to OHB version 4.23 HamClock. 

This script will download the script that you are going to need when entering the script listed below. As a side note, with some Pi OS's like Trixie, you will be prompted to enter your password whenever a "sudo" command is used. Just be aware that your password may be needed.  

 

4. The next command is: 

sudo fix-hosts

 I have read that you only need to enter if you are running Trixie or newer. In my case, I entered it anyway, as the instructions indicate you can if you would like to. I just did it as a just-in-case. 

5. After the above command has been entered, you may or may not be asked to reboot. I was not, but again I did anyway just to make sure. So I entered this command: 

sudo reboot now

 And it reboots the Pi, and if your HamClock starts up and is on the desktop, you need to again click on the lock and exit HamClock. 

6. You are now able to move over to either OHB, or you can also move to Hamclock.com backend. I will just be dealing with OHB in this post, but I will give you the command script for Hamclock.com backend as well. For moving to OHB enter this command: 

sudo ohb

If you want to move to Hamclock.com backend, then enter this script: 

sudo hcdc

7. Once you have done this, you can confirm that you have actually moved by entering this script: 

what

And it will confirm that you have moved to either OHB or HCDC, which over sudo command you entered above. In my case, the return script was: 

Your HamClock is set to Open HamClock Backend

   This confirmed to me that I had moved to OHB. 

 

8. The final step is to restart by entering this script: 

sudo reboot now

And once you have rebooted and HamClock goes through its startup, you will be asked if you want to go from version 4.22 to 4.23 and click YES.  

Updating

As a way of 2 side notes:

1. I did have to, for reasons not known to me, do the above process twice, as when I rebooted into the new feed for HamClock, I was not asked if I wanted to upgrade to 4.23. For some reason, it stayed on 4.22. Once I did steps 1-8 again, I was then asked to upgrade to 4.23.  

Ver 4.22 poor quality compared to 4.23

2. If you are operating Elwood's version of HamClock while it is loading, you will be asked if you want to upgrade to version 4.23, but as you say YES, you will be greeted with the following error message. To fix this, you need to change your back end. This is done by following the above 8 steps.

Radio Control Software: Taking the Complexity Out of Ham Radio

What Are the Advantages of Radio Control Programs?

Macros in Action

• The radio goes to 40m if not already there, on VFO A
• Antenna 2 is selected.
• CW mode is chosen.
• I am dropped into the middle of the 40m CW band segment.
• A custom audio level is set.
• Filter 1 (300Hz) is applied.
• NB, Digi select, RF gain, and NR are all set to custom values optimized for 40m CW.

The Split Operation Macro

• Dual watch is turned on.
• Split is turned on
• The appropriate antenna is selected based on the current band.
• VFO A and B are set to the same band
• VFO B is set to 1kHz above VFO A
• Filters are configured for both VFOs

    • May 15-17, 2026 - Booth 2206, Greene County Fairgrounds in Xenia, Ohio.  That is building E2/Tesla Hall, and we’re directly across from Flex Radio and Begali Keys in the big walkway between the 2 garage doors (so it’s nice and cool!).  We’ll be there from 9-5 on Friday and Saturday… and since we both have long drives ahead of us, we’ll be there at 9am and leave early (probably by 11) on Sunday… so make sure, if you’re waiting to visit us until Sunday, you get there EARLY!
    • Join us for dinner at Hamvention!
      • Friday:
        • Join Bill and I for dinner at BJ’s Brewhouse (2715 Fairfield Commons Boulevard, Beavercreek, OH 45431; it’s about 10 miles from Hamvention) on FRIDAY, May 15th, at 6pm.  Their menu is extremely diverse… pizza, pasta, burgers, steaks, etc.  Several Gluten-Free (although, because of their menu, there is a chance of cross-contamination; management told me to alert the server and they would do their best to avoid contamination) and Vegetarian options are available, too
      • Saturday:
        • Join Bill and I for dinner at Chuy’s Tex-Mex (2717 Fairfield Commons, Beavercreek, OH 45431) on Saturday, May 16th, at 6pm.  Bill and I are very keen on Mexican food, so this is somewhat of a no-brainer.  And there are Gluten-Free (again, possible risk of cross-contamination) and Vegetarian options available!

  • Bob, K4RFK via email:
    • How about you revisit setting up TLF and/or YFKtest and include how to set up contests that aren’t included in the initial downloads.  I’ve looked at their instructions and cant make head nor tails out of them.
