The command will be NAKed if the receiver has not been told
the radio is on the port specified by command
$PASHS,RDP,TYP.
• The air link speed depends on the type of modulation used
(GMSK or 4FSK) as well as the channel spacing used. The
tables below summarize the possible combinations.
– If a PDL radio is used:
d6
Air link speed.
For PDL:
• 4800: 4800 Bd, GMSK modulation
• 9600: 9600 Bd, GMSK or four-level FSK
modulation
• 19200: 19200 Bd, four-level FSK modula-
tion
For MDL: 4800, 7600 or 9600
For ADL, 12.5 kHz:
• 4800 (GMSK modulation)
• 8000 (GMSK modulation)
• 9600 (4FSK modulation)
For ADL, 25 kHz:
• 4800 (GMSK modulation)
• 9600 (GMSK modulation)
• 16000 (GMSK modulation)
• 19200 (4FSK modulation)
