Join us on **Easter Monday, 6 April**, for a **Parks on the Air (POTA)** outing from **Ticknock** in the Dublin Mountains. If you have not come across POTA before, it is all about bringing amateur radio into the great outdoors, setting up in a qualifying park, and making contacts from the field. We did a quieter test run on Bull Island recently and it went well, so this time we are opening it up to the wider **TOG community and the public**. We will meet at **10:30am** at the **Ticknock café** and then head off to find a good place to set up and operate. We expect to be on air for around **two hours**. You are very welcome to come along, help out, and even have a go on the radio using the **club callsign EI0TOG**. Jeffrey Roe, **EI7IRB**, will be leading the activation. Jeffrey is planning to cycle out, but there is parking nearby too. If radio is not really your thing, or you do not want to stay for the whole activation, Ticknock has plenty of walks so you can still join us for part of the outing. After the POTA activation, there are also IRTS 2m and 70cm contests running, so anyone who wants to keep the radio fun going is welcome to do that too. As always, this one is weather dependent. If the conditions are awful, we will give it a miss rather than spend another Monday getting soaked. Read the full details here: https://www.tog.ie/2026/04/pota-on-easter-monday-from-ticknock/ We hope to see some of you there in person, or hear from you on the bands.

📚Reading books and discussing them are two distinct experiences! Conversations about books and sharing insights help us better appreciate literature and enrich our lives. Let's grab a drink (alcoholic or non-alcoholic) and discuss books we're currently reading or have recently enjoyed—whether poetry, fiction, or non-fiction. Bring your physical book or e-reader. There's no formal structure or agenda—just books and good conversation.💬 It's a perfect place to get book recommendations and rediscover your reading momentum if you've hit a slump. We welcome readers of all backgrounds and interests! ⚠️**Something Happened?** If something unpleasant happened to you, it may happen to others. Even if it seems minor, don't hesitate to reach out to me. 🔍 **How to find us?** * When I reach the venue, I'll leave a comment in the meetup where the group is seated. Normally, the booking is in my name, so you can ask the staff for the group. * If you're unable to find us, leave a comment in the meetup page. I'll be able to guide you. We highly encourage you to move between tables and strike up conversations with fellow book lovers. These discussions about literature and reading recommendations are often the highlight of the event! As an organizer, I'm always looking for feedback about the event and suggestions for new events, so feel free to suggest ideas to me. 💡 I look forward to seeing you all! 😊

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.
