    Alpine head unit - resetting AM to 9KHz steps

    A couple on here have mentioned that the AM band on their radios jumps in 10KHz steps instead of 9KHz that is needed in Australia. The radio can be reset to Australian tuning requirements.

    This only appears to be a problem with the Alpine units fitted from 1999MY HSEs so if you have a different model then this won't fix it.

    The following is the prodecure for switching the radio to Australian (OCE) spec:
    • Turn key to accessories
    • Switch radio on
    • Press & hold I button then press CD button. SET UP will now be displayed.
    • Press button 6. MARKET USA will be displayed.
    • Press button 6. MARKET OCE will be displayed.
    • Switch off radio
    • Switch on radio
    Hope that helps those poor folk who've been struggling to listen to their favourite talk back host for years .

    Scouse: a thousand "Thanks" !

    About 18 months ago I emailed the folk @ "Roverville USA" on this. They replied the head units were market specific and that if I wanted a 9KHz step then I'd need to swap the unit over... didn't seem "right" but they're supposedly the experts so I accepted it (sort of)...

    Coasting's thread prompted me to check once again... this is most satisfying...the AM reception is now crystal clear and ABC News Radio/Radio National are as they should be ...

    at last, another feature which now works as it should!!

    I also discovered playing with the other buttons that the Alpine head unit has the capacity to receive "Emergency Broadcast" this is the " PTY31" toggle which apparently means "Program Type 31" ... ? Do we have those here?

    Last week I noticed that on some FM stations the song title and other info was being streamed like a SkyNews headline across the dial... I had not seen this before... too busy watching the road

    Onya Scouse - I don't have a stock radio but appreciate you going to the trouble...

    Hoges - I think that scrolling display thing you're seeing is RDS (Radio Data System), commonly used in Europe. I didn't know we had any stations using the sub-channel here yet, but I'll have to keep an eye on the stereo now...

    More info here [ame=http://en.wikipedia.org/wiki/Radio_Data_System]Radio Data System - Wikipedia, the free encyclopedia[/ame] including a list of Program Types (PTY).

    Cheers, Paul.

    Great info Paul, many thanks Seems the OEM head unit is/was quite capable!
    cheers
    A.

    PS: just Googled RDS in Australia...fascinating...RDS offers a whole new world of potential distraction on the FM dial to take one's mind off the boring task of driving...can watch adverts streaming on the RR radio dial... and they complain about mobile phones!!

    Thumbs up This cures the RDS problems too!

    Thank you thank you thank you!

    I've just arrived from the UK, and bought a P38 here of the same vintage as in the UK (1999)... and the American style tuning was driving me mad: the dealers couldn't understand me when I explained that I needed to change the radio to UK/Australian tuning rather than the American!

    For reference, the change in the market settings also effects the PTY code for the RDS (this is displayed when you press the i button when a station is transmitting full RDS data).

    When the PTY code (for Programme Type) is set for the American market (where RDS is called RBDS) the Radio PTY code 11 comes up as "Oldies" however in Australia the UK coding is used, so PTY code 11 should be "Rock".

    Another one with code 10 is "Pop" in UK & Oz, whereas it is "Country" in the USA - but the RDS radio displays the USA station type in my 1999 HSE!

    No longer however - all is as it should be.

    Incidentally, in the UK pretty much every station - even small Community & the hundreds of Pirate Stations - have RDS data. However in Australia it does seem to very unusual: in Metropolitan Sydney only WSFM, Star, 2dayFM, Mix 106.5, The Edge, Nova, Vega, Wave, and Triple M transmit RDS data: and I was fed up with Triple M coming up as "Oldies": with the change to the radio, it now comes up as it should do as "Rock".

    Horrah!

    Good to hear that this is helping a few people out. It seems to be a more common problem than I thought.

    Alas ! one would hope so... however,the general tech knowledge of the usual "here today, gone down the road next week for an extra $2" type warming seats in the average dealership ...all makes included... leaves a lot to be desired. If you find a "good one" , ...celebrate

    The screen on mine is unreadable so it doesn't matter what the RDS displays.

    I can't get that on mine, although I've tried all the options after entering setup... which button did you press?

    ...incidentally, returning to my "dealer couldn't understand me..." comment... at one stage when I was trying to get them to understand that I wanted to change it from 10 to 9 steps, they did try and sell me a completely new head unit because the guy behind the counter assured me that if it was tuning in 10kHz steps, then probably it was "broken".

    Sigh.

    Although I can see his point, as I did initally go in to ask if there was any cure to suggest for the CD multiplayer playing the first 30 seconds of each disc, and then stopping. I've yet to fix that one: a CD lens cleaner hasn't worked...
