AI ELMER
Welcome aboard, OM. Ask me like you would ask a local Elmer at the club. I’ll explain ham radio in plain English — antennas, bands, DX, FT8, propagation, station setup, coax loss, contesting, and operating technique. 73!
Live propagation resource

Enter a callsign and country/state in the top right. AI Elmer uses that location plus the current solar numbers to explain which HF bands are most likely to work. Solar values are pulled from NOAA SWPC when available, with a safe fallback if the feed is unavailable.

Ham Radio Tools

Practical calculators every new ham needs. All math done instantly — no internet required.

📐 Antenna Length Calculator

Find the wire length for a dipole, vertical, or OCF dipole. Uses the standard 468/f formula.

Enter a frequency and click Calculate.
📉 Coax Loss Calculator

How much signal are you losing in your feedline before it even reaches the antenna?

Choose coax, length, and frequency, then calculate.
⚡ Power & dB Converter

Convert between watts and dBm, or calculate how many dB a power change represents. Essential for understanding gain and loss.

Enter watts and click Convert.
📊 SWR & Reflected Power

Enter your SWR reading and see how much power actually reaches the antenna vs. bounces back. Helps you decide if your SWR is acceptable.

Enter SWR and power, then calculate.

📻 Repeater Offset Calculator

New hams always struggle with repeater offsets. Enter the output frequency and get the input (where you transmit) automatically.

Enter repeater output frequency and click Calculate.
Standard offsets: 2m = ±600kHz · 70cm = ±5MHz · 6m = ±1MHz
〰 Wavelength Calculator

Convert between frequency and wavelength. Useful for understanding band names, antenna spacing, and propagation.

Enter a frequency and click Calculate.
🔋 Ohm's Law & RF Power

Calculate voltage, current, resistance, or power. Fill any two fields and get the other two. Essential for understanding radio circuits.

Fill in any 2 values and click Solve.

First QSO Script Builder

The #1 fear of every new ham is “I don’t know what to say.” Fill in three fields and get a word-for-word script you can read right off this screen.

Tell Elmer about your first contact
●●● Elmer is writing your script...
YOUR QSO SCRIPT Read this word for word — it’s okay!
What to expect on your first contact

⚠ Most common mistakes

  • Saying “over and out” (pick one)
  • Not identifying with your callsign
  • Holding the PTT before speaking
  • Transmitting without listening first
  • Saying “radio check” repeatedly

✓ Procedure words to know

  • Over — your turn to transmit
  • Out — conversation is done
  • Go ahead — please transmit
  • 73 — best regards / goodbye
  • QRZ? — who is calling?

🔐 ID rules (FCC)

  • Say your callsign at start and end
  • ID every 10 minutes during contact
  • Use English for station ID
  • Portable: add “/portable” or location
  • No ID needed for unmodulated testing

🎙 What to actually say

  • Signal report: “You are 5-9”
  • Your name and location
  • Your antenna and radio setup
  • Weather if nothing else comes to mind
  • Ask what they are running for equipment
