AM Radio Reception in S60R

Good luck we're working on the same problem with many cars.

In the past there was antenna tuning adjustment at the rear of the radio near where the coaxial antenna cable enters the radio. The procedure is to tune the radio to a weak station at the bottom end of the band (550KHz) and adjust it for maximum signal. I do not know if newer radios come with this necessity.

SUBJECT: Poor AM Reception

CHASSIS:

REFERENCE: Service Bulletin 39-0018 and 39-0025

DESCRIPTION:

Cases have been reported in which AM static will increase and maintain a higher level, resulting in

complaints of poor AM reception. The increase in AM static may be triggered by several reasons,

including: bumps in the road, closing the doors. The AM static will stop by several reasons, including:

Central Door Lock activation, rear defrost activation, touching the trim covering the antenna amplifier.

SERVICE:

It has been determine the increase in AM static is due to a loose connection between the antenna

amplifier and antenna cable. To improve the connection (and AM reception), this Tech Net Note

provides instructions to install a brass strip, Part Number 30657370.

The brass strip must be bent as illustrated:

NOTE: It is critical not to exceed the 8 mm (5/16") length. If this length is exceeded, it will result is

worse reception.

Install the brass strip into the antenna amplifier as illustrated:

Install antenna cable so that the locking clips are not on top of the brass strip. It may help to push the

locking clips to help seat properly.

NOTE: After the antenna cable has been installed, pull the antenna cable to verify the locking clips are

holding the antenna cable in the proper position. If the antenna cable releases easily, the locking clips

were not seated.

I would like to have a copy, too. What type of file is it that is not allowed (or is it too big)? If it is just the file type you can change the type (such as 39-35.pdf to 39-35.pd_ and then you can send it.

Thanks Glenn,

Allen

this helps all Glenn

Glenn

That is brilliant help, thank you. My car runs out of warranty early next year, so I will now have the ammunition I need in case they don't want to do anything about it!

Thanks again Glenn very much appreciated.

Mark

Thank you Glenn, perfect!

Allen
