AF1=
...
AF25= Alternative Frequency If the station broadcasts on more than one frequency using translators or repeaters,
these are typically set to each of the frequencies used in the broadcast network.
Sample calculation for 98.5 MHz: (98.5-87.8) x 10 = 107
Example: AF1=107
NOTE: there is no method to disable AFs in this protocol.
DI= Decoder Information Single hex digit, range 0-9 and A-F (case insensitive) that encodes the flags Stereo(1)/
Mono(0) - bit 0; Artificial Head (Yes=1, No=0) - Bit 1; Compression (Yes=1, No=0) - Bit
2; and Dynamic (Yes=1, No=0) - Bit 3
Example: DI=3 (Stereo, Artifical Head=Yes, Compression=No, Dynamic=No)
MS= Music/Speech Typically set to 1 if the station broadcasts music, otherwise set to 0.
Example: MS=1
TEXT= Radio Text Accepts a 1 through 64 character ASCII string, displayed on receivers that support RDS
radio text.
Example: TEXT=Tears for Fears - Shout (1985)
ECHO= Echo on/off If set to 1, the RDS encoder will echo back characters that are sent to it. If set to 0, the
encoder will only send responses.
Example: ECHO=1
DATE= Current UTC date Format is strictly YYYY-MM-DD. Sets the current UTC date for 4A date/time broadcasts.
This is a non-volatile setting.
Example: DATE=2016-04-04
TIME= Current UTC time Format is strictly HH:MM:SS, 24-hour format. Sets the current UTC time for 4A date/
time broadcasts. This is a non-volatile setting.
Example: TIME=17:23:05
UTC= UTC time zone offset Range is 0 to 24, 32 to 56. Sets the current time zone. To calculate this value, multiply
the time offset by 2 and add 32 if the time offset is negative. For Newfoundland (UTC-
3.5), 3.5 x 2 = 7, and add 32 (since the time zone is negative) to yield 39. This is a non-
volatile setting.
Example: UTC=39
