TD Jackaroo am reception

Hi there Keith, The problem with the AM reception on the jacks is that the injection computer uses an ac power circuit causing the interference. When i was at Holden they had a fix which required installing a new aerial unit (motor and mast) we did a lot under warranty and it seemed to fix the problem, the existing units seemed to have bad internal earthing. I am unsure if the newer fixed 'whip' antennas on the later jacks also suffer the same problems. But this may be an option. I saw all manner of shielding and bonding used around the computers but it seemed to be a bit of a bandaid solution. I think it also causes problems with HF / codan radios, as people who had these fitted had the antennas fitted at the rearmost point of the car with well bonded mounts. If you complained of this while under warranty then you should be in with a chance of getting a new unit fitted as this is a well known problem. Speak with the workshop foreman about getting the latest tech updates off their system, so that you are fully armed if you try it on with the service manager. Also the aftermarket tuner in the pioneer deck has a very high sensitivity so this is why it is worse than the factory unit. Hope this helps, BradLife is short- but there's always time for a yarda.

AM? Is that still going?.. dont think my Alpine WMA player actually has AM, havent looked...

And jeez does it pierce me off when you learn that some people have had a possibly effective remedy for this under warranty but other owners never hear of it ! Bloody crooks in my view. I got a supressor fix for my 99 Jack under warranty.
Of no use in the sticks - not bad in the city - new motor and mast never communicated to me. Interefence still an issue though. What this all means for HF radios is that you cannot communicate whiole mobile. If it was not for this design cock-up, I could reliably converse over 3000k anytime and make radphone calls too.Get me outa these suburbs !

I had exactly the same problem.

Pathetic AM reception on the Jack, and it got even WORSE when I fitted a radio/CD/MP3 player.

Still, the brilliant features of cramming seemingly endless MP3 tracks onto a disc sort of got over the problem a bit.

I don't have the Jack any more and my new vehicle has a radio that works PROPERLY
