[ACARS] Interesting Capture on HF DL

[Mike]

Hi Gang,

I have just captures this downlink from Lufthansa 8400 which is halfway =
across the Tasman Sea between Auckland and Melbourne.  It appears that =
the content is a check of which ground stations are up and operating =
within range of the aircraft.  It is interesting to note the propogating =
frequencies and the tuned frequencies, how does this relate to Charles =
Brains list in the PCHFDL manual??
