NAD 7130 FM stereo signal (on off again and again)

Due to the age of the North America/Canada model, I would check the power supply for stability.

Did you try new/different RCA cables?

FM radio settings
Note: You can only see the FM radio settings when you have selected ‘FM’ as the radio source.
FM stereo option
You can choose between stereo or mono reception when listening to FM radio. Mono may improve
clarity where stereo signals are weak.
To change between Stereo or Mono reception:
1. Press the Menu button.
2. Turn and press the Select dial to choose ‘Audio Setting’.
3. Select between ‘Stereo Allowed’ or ‘Forced Mono’.
FM scan
You can choose whether your Elan E3 automatically stops at the next available FM station or the next
available FM station with a strong signal when scanning for an FM station. To change the FM scan
setting:
1. Press the Menu button.
2. Turn and press the Select dial to choose ‘Scan Setting’.
3. Select between ‘Strong Stations Only’ or ‘All Stations’.

DAB settings
Note: You can only see the DAB settings when you have selected ‘DAB’ as the radio source.
Full scan
You can use the ‘Full Scan’ (autotune) function to automatically scan for new digital radio stations and
remove inactive ones.
To carry out an autotune:
1. Press the Menu button.
2. Turn and press the Select dial to choose ‘Full Scan’.The number of stations found will be
displayed during the autotune.
When the autotune has finished, your Elan E3 will tune to the last station that you were listening to. If the
last station you were listening to is no longer available, your Elan E3 will tune into the first station in the
alphabetical list.
Manual tuning
To manually check the signal strength of a known channel:
1. Press the Menu button.
2. Turn and press the Select dial to choose ‘Manual tune’.
3. Turn and press the Select dial to choose the channels.

if you are reffering to a radio fm receiver, the issue is the signal strength is too low.so the multiplex transmission cannot be correctly unscrambled.mono reduces the cross channel interference.
use a high gain 12 db or above external vhf antenna to solve this problem

Hello,

my first question is does the light come on when you turn to Tape, Phono, Aux selection? If no lamp is blown, if it does come on then your tuner need to be serviced. FM tuner work is NOT for a novice. I would be glad to take a look at the unit.

Thanks

Hello
If the set receives FM signals without any problem, and only fails to receive AM signals, the IC [integrated circuit] used in it is faulty. The number of the IC used with your radio is CXA 1376AS. It is a replacable type IC, and can be bought from most of the electronic spare part shops at your town. If you want further details about its service manual, get me by Fixya. OK.

Maybe an FM amplified indoor antenna could help you to get a stable FM signal.

Not very specific. Do you have the manual?

The following is from a VSX-03TXH manual. It ain't pretty but it may help.

I'm posting it in multiple parts due to space contraints.

Chapter 6:

Using the tuner

Listening to the radio

The following steps show you how to tune in to FM and

AM radio broadcasts using the automatic (search) and

manual (step) tuning functions. If you already know the

frequency of the station you want, see Tuning directly to a

station below. Once you are tuned to a station you can

memorize the frequency for recall later-see Saving

station presets below for more on how to do this.

1 Press the FM/AM button to select the tuner.

2 Use the FM/AM button to change the band (FM or

AM), if necessary.

Each press switches the band between FM and AM.

3 Tune to a station.

There are three ways to do this:

Automatic tuning

To search for stations in the currently selected band,

press and hold TUNE ?©/?? for about a second. The

receiver will start searching for the next station,

stopping when it has found one. Repeat to search for

other stations.

Manual tuning

To change the frequency one step at a time, press

TUNE ?©/??.

High speed tuning

Press and hold TUNE ?©/?? for high speed tuning.

Release the button at the frequency you want.

Improving FM stereo sound

If the TUNED or STEREO indicators don't light when

tuning to an FM station because the signal is weak, press

the MPX button to switch the receiver into mono

reception mode. This should improve the sound quality

and allow you to enjoy the broadcast.

Using Neural THX

This feature uses Neural Surround™, THX® technology to

achieve optimal surround sound from FM radio.

• While listening to FM radio, press AUTO/DIRECT for
Neural THX listening.

am is a signal sometimes you can and sometimes you can't, all you can do is select the am station you want, move the radio around till you get the station and don't move anymore

A 712 is not set up to use an Ipod USB dock.  You can buy a dock that will use RCA jacks into an old stereo - Apple sells them, others too.  Then the Ipod sits up and you can look at it.  Or you can buy the 1/8" stereo plug to two RCA plugs that Radio Shack has been selling for 30-40 years, plug one end into your Ipod headphone jack, and run the two RCA plugs into your Aux input.  That costs about $5, and is easy as pie.  An Ipod will play through any old receiver, but the USB docks will not plug into them.
