The RDS Forum presented to IEC TC 100 a new proposal to replace the current IEC 60315-9 - Methods of measurement on radio receivers for various classes of emission – Part 9: Measurements of the characteristics relevant to Radio Data System (RDS) reception.
The IEC 60315-9 was issued first in 1996 and never updated since then. The RDS Forum proposes to replace this totally outdated text by this new proposal and then simply to delete the old specification. The fact that the old specification is also bundled with other radio receiver measurement standards is considered by the RDS Forum to be very inappropriate in the particular case of RDS. Therefore this new specification should preferably be issued with a totally different IEC reference number. The IEC TC 100 allocated now the new project no. 62634 to this proposed new standard, to be issued in early 2011 then.
Nowadays RDS integrated FM receiver chips are being manufactured in a very large number (over 200 million pieces only in 2007). In the current IEC 60315-9 publication the target values quoted for RDS performance to be achieved were based upon tuner technology of the eighties and in addition one of the dominant RDS constraints, i.e. ARI, has now completely disappeared. Updating the IEC 60315-9 was considered by the RDS Forum to be meaningless and that was the main reason to propose to drop then the IEC 60315-9 totally.
The new methods of RDS measurement specification is recommended by the RDS Forum to be used instead. Hopefully it will also contribute to achieve well performing RDS products.
