Hello!

The internet automatic translation engines are really horrible, you know :)

Anyway, we have found that there's sometimes a problem with RDS MAX 2.0

In order to fix the problem you have to do the following:

1.) Replace C12 with 10nF
2.) Replace C13 with 47nF

When the stereo encoder is activated and you have connected the
19KHz pilot cable to the 19KHz input, turn P1 all the way towards IC9.

Led diode D2 will be entirely off in this position.

3.) Connect a BAT43 or BAT85 diode (use 1n4148, if nothing else is at
hand) over the 10K (R19 - next to D2) . It ring should be pointed
towards D2.

This will solve your problem.

If your RDS level is too low, I recommend replacing the 39K
resistor (R6) with 1Mohm (or 2M2).

All shipping units from today onward will have these mods implemented.

Just some of the RDS MAX 2.0 units have had a problem with this and
the mod only concerns a limited number of RDS MAX 2.0 units.

Have you replaced the right components?

This was for RDS MAX 2.0, do not do this on 1.0!

noventafm eres de España?.. Alguien sabe que "codigos" de pais y area y todo eso hay que meter para España?

¿Y COMO SE PUEDE HACER PARA QUE LAS PANTALLAS CAMBIEN MAS RAPIDO? Aun poniendolo al "1" tarda demasiado en cambiar (unos 3 segundos)

GRACIAS

UPDATE!

If the fix did not work for you than this surely will.

Anyway, this problem was caused by the difference between
batches various versions of the 4046 chip.

This is a solution for everyone:

C11 (Next to R10 - 22K and P2).
If IC9 = CD4046 than C11= 3n3
If IC9 = 74HC4046 than C11= 47n

C13 (Next to C12 and R12).
If IC8 = CD4046 than C13= 1n
If IC8 = 74HC4046 than C11= 10n

Take it out and replace it.

Only do this if you're having problems.
If your RDS MAX works just leave it alone.

All units shipped recently are working normally.
