RDS95

(eRT)(RDS2)

RDS95 is a light software RDS encoder for linux

RDS95 follows the IEC 62106 standard (available at the RDS Forum website)

Diffrences between IEC 62106 and EN 50067

The newer standard which is the IEC one, removes these features:

• MS
• PIN
• LIC
• DI (partially, only dynamic pty is left)
• EWS (now ODA)
• IH (now ODA)
• RP
• TDC (now ODA)

Unique features

RDS95 is the only (as far as i can tell) encoder to transmit the 9-bit AF codes

Commands

PS

Sets the Program Service: PS=* RDS *

PI

Sets the PI code: PI=FFFF

TP

Sets the TP flag: TP=1

TA

Sets the TA flag and triggers Traffic PS: TA=0
May be overridden by EON

DPTY

Sets the DPTY flag: DPTY=1
Formerly DI

SLCD

The 1A group where ECC is sent can also be used to send broadcaster data: SLCD=FFF

CT

Toggles the transmission of CT groups: CT=1

AF

Sets the AF frequencies: AF=95,89.1
Clear the AF: AF=

AFO

Sets the AF frequencies for the ODA 9-bit version which enables AF for 64.1-88 MHz: AFO=69.8,95.0,225 (LowerFM,FM,LF) Clear the AFO: AFO=

TPS

Sets the Traffic PS: TPS=Traffic! (default not set)
TPS is transmitted instead of PS when TA flag is on

RT1

Sets the first radio text: RT1=Currently Playing: Jessie Ware - Remember Where You Are or TEXT=Currently Playing: Jessie Ware - Remember Where You Are

RT2

Sets the second radio text: RT2=Radio Nova - Best Hits around!

PTY

Sets the programme type flag: PTY=11

PTY values are diffrent for RDS and RDBS, look for them online

ECC

Sets the extended country code: ECC=E2
Note that the ECC is depended on the first letter of the PI, for example PI:3 and ECC:E2 is poland, but PI:1 would be the czech republic

RTP

TODO: RTP

LPS

Sets the LPS: LPS=NovaFM❤️
Note that LPS does UTF-8, while PS, RT don't

ERT

TODO: ERT

PTYN

Sets the programme type name: PTYN=Football

AFCH

TODO: AFCH

UDG1

Sets the user defined group, max 8 groups: UDG1=6000FFFFFFFF

UDG2

See UDG1

G

Sends a custom group to the next group available: G=F100FFFFFFFF or G=00002000AAAAAAAA for RDS2

RT1EN

Enables RT 1: RT1EN=1

RT2EN

Enables RT 2: RT1EN=2

RTPER

RT Switching period, in minutes: RTPER=5

LEVEL

Sets the RDS output level: LEVEL=255

RESET

Resets the internal state of the encoder: RESET

PTYNEN

Enables PTYN: PTYNEN=1

GRPSEQ

Sets the group sequence for stream0, available groups:

• 0: 4 PSs
• 1: ECC
• 2: RT
• A: PTYN
• E: EON
• X: UDG1
• Y: UDG2
• R: RT+
• P: eRT+
• S: ERT
• 3: ODA
• F: LPS
• T: Fast tuning info
• U: ODA AF

GRPSEQ=002222

RDSGEN

Sets the rds generator level:

• 0: No streams
• 1: Stream 0 only
• 2: Stream 0 and 1

RDSGEN=1
