[EAS] Sirius/XM on NPT

[Harold Price]

Tim,

There is no "processing delay" per se.  For a CAP message with audio, 
like the NPT, there is a delay after the CAP message is received and 
logged and before transmit until the audio file is downloaded - your 
mileage may vary, my several test ENDECs took between one and three 
seconds to download the 224kb file.  It might be longer.  If it is 
too long, the ENDEC will do TTS instead.

For an analog alert, the incoming alert isn't logged until at least 
two of the three headers arrive, if you decode only header 1 and 3, 
that's longer.  An "automatic" action alert like the NPT won't start 
relaying until after the end of the incoming headers and the 
attention tone (but before the rest of the audio and EOM.  For the 
NPT, about 15 seconds.
