DTMF Commands

GB3TY has a few useful DTMF codes, which are detailed below.

METAR INFO

METAR (METeorological Aerordrome Report), is a standard message providing current weather conditions at an airport for pilots, usually issued every 30 mins, and is critical to flight safety. While normally used by pilots, it can still be useful to any amateur radio enthusiast for up-to-date weather. 

  1. Use 5# to enter METAR INFO mode.
  2. Choose which airport to receive from the list below.
  3. 1# - EGLF, Farnborough Airport
  4. 2# - EGLL, London Heathrow Airport
  5. 3# - EGKK, Gatwick Airport
  6. After listening, use # to exit METAR INFO mode.

ECHOLINK

Echolink is a Voice over IP (VoIP) system that allows amateur radio operators to communicate over the internet. It bridges the gap between the internet and RF, and allows users to access repeaters through their own phone/laptops. It can also be used to link distant repeaters, so users can connect with distant operators over RF, bridged through the internet.

  1. Use 2# to enter METAR INFO mode.
  2. Dial the Echolink node using the following format:
  3. <NODE ID># for example: 9999# would dial the node 9999, which is the Echolink Test node. 
  4. To Disconnect from the connected node, use # to return to Echolink mode, where another node can be dialled.
  5. To exit Echolink entirely, use #.
