Every club runs into the same problem. The programme chairman needs a speaker for next month, nobody has volunteered, and building a talk from nothing takes more evenings than most of us have. These presentations exist to solve that. Take one, put your callsign on the title slide, and you have a programme.
They are built from the reference pages on this site, so the written detail behind every slide is already here if somebody in the room asks a harder question than you expected. Each carries speaker notes on every slide — not a script to read out, but the background, the numbers, and the places where the sources disagree.
Everything on n6jet.com is released free of copyright. You may use, copy, and distribute anything here for any purpose, commercial or not, without permission and without attribution. That applies to these presentations exactly as it applies to the pages.
There is nothing to buy, no sign-up, no email address to hand over, and no account to make. Present one as your own talk if you like. Change it, cut it, add to it, merge it with your own material. You owe nobody a credit slide.
The files are ordinary .pptx. PowerPoint, Keynote, Google Slides and LibreOffice Impress all open them. Photographs are works of the U.S. federal government and carry no reuse restriction — the Credit: NIST lines are a courtesy, not an obligation, and you may delete them.
The talk to give before anyone chooses a mode. What the six digital voice modes are, where each came from, why they feel harder than they are, what the radios cost, and how to start without spending anything.
Ends by sending the room to a live dashboard to listen before buying anything.
Built from the Start Here guides: Top Ten Must-Knows · What Bands Is Digital Voice On? · Each Mode Explained (in Brief) · Rosetta Stone · Pros and Cons · Which Mode Is Right for You? · Where to Listen
An introduction to DMR for operators who already know analog. Where the standard came from, the engineering trick at the heart of it, why you link instead of tune, and an honest account of what it costs you to get started.
Ends with a four-step way to start that costs very little and scales without ever starting over.

WWV, WWVH and WWVB — and the world's other standard-frequency and time-signal stations, past and present. The talk works through what a time station actually sells, how the signals are modulated second by second, the three American stations in detail, and who else is still transmitting.
Photographs throughout, from the NIST station galleries: the antenna array at Kokole Point, the inside of a plate-modulated transmitter, the helix house at Fort Collins, and the original WWVH at Kihei on Maui.
Companion reference page: Time Stations: Standard-Frequency and Time-Signal Radio, Past and Present — every claim in the deck is written up there at greater length.
As it stands. Open it, replace the blank on the title slide with your callsign and club name, and present. The speaker notes carry what you need to say around each slide.
As a starting point. Most club talks run shorter than thirty minutes. Cut whole sections rather than trimming slides evenly — the deck is built in blocks and each one stands on its own. The closing slide works after any of them.
As a template. If you have your own material and no time to make it look presentable, delete the content and keep the layouts.
One suggestion worth more than any slide: if you can get a receiver into the room, tune 10 MHz before you start and let the audience hear the ticks. Thirty seconds of that teaches the modulation section better than the diagrams do.
