8.33 kHz channel converter
Civil VHF airband in Europe uses 8.33 kHz spacing. Many radios show a channel (three decimal places) that is not always the same as the actual transmit frequency. This converter uses the public ICAO mapping for 118–137 MHz so you can go from the number on the faceplate to the carrier, and back.
Cross Reference UK uses this when checking ATIS/VOLMET listings — not as a way to build an operational ATC directory. If a listing and a radio disagree by a few kilohertz, try 8.33 before you file a “wrong frequency” report. Longer background: airband for receive-only listeners.
