Hi All,



I have a specification on my FM TX,



RDS level 2KHz, deviation +- 75KHz.



Question:



  1. If my FM TX freq is 100MHz, where is the RDS freq ?
  2. The deviation means when RDS is trasmitting ( and keep trasmitting data repeat), I check the tone deviation of RDS?

Thank you so much!



Best regards, Boki.

Hello Boki,

AFAIK it rides on a 57kHz subcarrier.

Best would be to read up on the spec:
