Global

On US Global High Frequency System (GHFS) frequencies. Best frequencies to monitor are those guarded by MacDill and Ascension. After initial contact on one of the published GHFS frequencies, listen closely for them to switch to a non-published frequency to pass traffic. Aircraft call signs are "GULL-nn" or "TEAL-nn" (where nn is a 2-digit number), "NOAA-42", "NOAA-43 and "NOAA-49". The GULL and TEAL aircraft are based at Keesler AFB, Biloxi, MS. The NOAA aircraft are based at MacDill AFB, Tampa, FL.
