Pro-Grade Ham Radio Displays: Integrating OpenHamClock into PiSignage

758 words, 4 minutes read time.

A Helping Hand Needed for a Fellow Programmer

I’m reaching out to see if you can lend a hand to a talented software developer who’s currently on the job hunt. With over 30 years of experience in C#, .NET (Core/6–8), REST APIs, SQL Server, Angular/Razor, Kubernetes, and cloud CI/CD, he’s a seasoned pro with a proven track record of leading modernization projects and delivering production systems.

Some of his notable accomplishments include DB2 to SQL migrations, building real-time SignalR apps, and developing full-stack API and frontend projects. Based in Southeast Michigan, he’s looking for senior engineering, architecture, or technical lead roles that will challenge him and utilize his skills.

If you’re in a position to help, you can check out his resume and portfolio at http://charles.friasteam.com.

Let’s all look out for each other – if you know of any opportunities that might be a good fit, could you please consider passing this along to your network?

If you are a ham radio operator, you know that a HamClock is the ultimate shack companion. But what if you want to move beyond a dedicated small screen and integrate that data-rich display into a professional digital signage environment?

By using PiSignage, you can rotate your HamClock with other station metrics, weather, or club announcements. However, getting a clean, secure, and “pop-up free” experience requires a few tricks.

In this post, I’ll show you how to deploy OpenHamClock using Docker and how to strip away the UI clutter for a seamless kiosk experience.

The Setup

To follow along, you will need a PiSignage server instance. I personally run mine as a Docker container, which keeps the server stack isolated and easy to back up.

1. The Docker Compose Configuration

PiSignage and modern browsers often require secure contexts (HTTPS) for certain features. Since the standard HamClock output is HTTP, we’ll use a two-service setup: the clock itself and a lightweight SSL-wrap sidecar using socat and openssl.

docker-componse.yml

 services:    openhamclock:      image: ghcr.io/accius/openhamclock:latest      container_name: openhamclock      expose:        - "3000"      environment:        - CALLSIGN=<CALL SIGN>        - LOCATOR=<Grid Square Locator>        - THEME=dark        - UNITS=imperial      restart: unless-stopped     ssl-wrap:      image: alpine      container_name: hamclock-ssl      ports:        - "3000:3000"      command: >        sh -c "apk add --no-cache socat openssl &&                openssl req -x509 -newkey rsa:2048 -keyout /tmp/key.pem -out /tmp/cert.pem -days 365 -nodes -subj '/CN=localhost' &&               cat /tmp/cert.pem /tmp/key.pem > /tmp/combined.pem &&               socat OPENSSL-LISTEN:3000,cert=/tmp/combined.pem,verify=0,fork,reuseaddr TCP:openhamclock:3000"      restart: unless-stopped 

2. Silencing the “What’s New” Pop-ups

When using HamClock as a signage element, you want it to be “set and forget.” The “What’s New” slide-ins are helpful for desktop users but ruin a clean kiosk display.

While there is a formal change request pending for a toggle, you can currently “force” these elements to stay hidden by injecting a bit of CSS directly into the distribution files. Run this command within your app environment:

find /app/dist -name "*.css" -exec sh -c 'echo "div[style*=\"whatsNewSlideIn\"], div[style*=\"backdrop-filter\"] { display: none !important; }" >> {}' \;

3. Setting Up the Slide in PiSignage

Once your containers are humming along, you need to tell PiSignage how to display the clock.

Create the Weblink Asset

1. Log in to your PiSignage Admin Panel.
2. Navigate to Assets > Add > Weblink.
3. Fill in the details:
   • Name: OpenHamClock
   • Link Address: https://<YOUR-HOSTNAME>:3000/?kiosk=true
4. Click Save.

Pro Tip: The ?kiosk=true suffix is critical. It tells HamClock to hide its own internal menus and headers, giving you a dedicated, high-contrast dashboard perfect for a wall-mounted display.

Deploy to Your Player

1. Go to Playlists and add your new “OpenHamClock” asset.
2. Set the Duration: Set this to 0 for a permanent display, or a high number (like 300 for 5 minutes) if it’s part of a rotation.
3. Go to Groups, select your player, and deploy the playlist.

Your screen should refresh and show a beautiful, clean HamClock interface within seconds!

Running PiSignage in Docker?

For those of you looking to keep your entire server stack contained, running the PiSignage central server in Docker is the way to go. It keeps your host OS clean and makes management a breeze.

If you’d like me to discuss how to set up a dockerized PiSignage server, please comment below!

Call to Action

Getting this stack to play nice wasn’t a “one-and-done” install. It was a hard-fought process that took multiple attempts to finally crack the code on bypassing those “What’s New” screens and forcing a clean kiosk display. But the victory is in the uptime.

Don’t just lurk. If you’ve got the guts to show how you’re rebuilding your station on the wreckage of the old ways, drop a comment below. How are you occupying the victory today?

Der letzter Feinschliff vor Weihnachten an der #Wetter #WebApp: Alles jetzt schön parameterisiert und die Layer können nun gezielt per URL aufgerufen werden. Ideal für den #Kioskmode. Eine Demo zum Testen gibt's hier:

Die Dokumentation und Sources gibt es auf #Codeberg, have fun und schöne Weihnachtstage.

Advice needed: I want to set up #Linux Kiosk PCs. Users must log in with a card ID and password that are verified via a PHP webservice against a MariaDB.

The challenge: I need the Linux desktop login (e.g., via a Display Manager like LightDM/GDM) to authenticate against the custom remote service.

How can I implement this? Custom PAM module? Python-pam? Scripts?🤔

Die Nacht war kurz.

Gestern habe ich noch eine einfache Möglichkeit gefunden einen #Raspberry mit Display im #Kioskmode zum Zentraldisplay unseres ##homeassistant zu machen.

Was ich nicht bedacht hatte: für das 7“ #Touchdisplay braucht es ein spezielles Layout.
Also Helfer und Automationen am Fließband erstellen um den #WAF auf ein überlebensfähiges Niveau zu bringen.
Das hat dann doch länger gedauert als gedacht.

Did some more #coding on my #Oglaf #userScript, since I wanted to add a sort of #KioskMode as well, that showed just the current image as well as the image alt/title.

Ended up adding the page title as well to the list of image descriptions, and a history of the last 2 comic's descriptions, as I noticed I sometimes didn't realise I forgot to actually read them till I was one or two comics further along.

Should perhaps add a thumbnail next to each of them too.
