AI SKILL

DAB+ & FM Planner

Teaches an AI assistant to work out how many DAB+ services fit in a multiplex with a tested capacity calculator, and to explain the basics of FM pre-emphasis, deviation, MPX and RDS.

What it does

List your services with bitrate and protection profile. It sums the capacity units.

  • Multiplex capacity. Capacity units per service (EEP-A and EEP-B) and what is left out of 864.
  • Trade-offs. More services, more robustness or better audio: the choice stays with you.
  • FM basics. Pre-emphasis, deviation, MPX and RDS, pointing to the regulator for the limits.

Where it helps

For planning DAB+ ensembles and understanding FM chains. Table values are for EEP set A and should be checked against ETSI EN 300 401. No coverage, power or licence advice.

How to use it

  1. Add the skill folder to Claude as a Skill, or open the universal prompt file and paste it into ChatGPT, Gemini or any assistant (custom GPT, Gem, system prompt, or the start of a chat).
  2. Describe your problem in your own words. The skill asks the few questions that change the answer.
  3. Check the answer against your equipment manuals and, where it matters, a measurement.

Limits

A skill makes an AI assistant more careful, not infallible. It cannot see your equipment, it can be wrong, and standards and platforms change. Every skill lists its sources and what it does not know, and shows whether a person has validated it. Mains power, RF power and structural work always need a qualified person.
