The sound on AM channel is very poor while that on FM is excellent.What is the cause of this problem ?

I enjoy listening to SW station but the problem with the Radio is that you must use either ear phone or put the radio close to you ear to listen to stations on AM/SW channels.

Usual problem can be traced back to faulty electrolytic capacitors, solution is to replace all capacitors and make sure any leakage is cleaned up with needed repairs. Contact me if you need help.... poikaa(at)yahoo(dot)com

On AM radio, there is often a sound, like a hammer hitting a 55 gal. drum interrupting the program. Does not do it on portable radio carried in the car.

all stations AM?

is the engine running?

for get the portable, some have vastly better a/m radios than any car has. in fact many cars radios a/m OR of horrid quality.

i can tell you why but its boring. (AGC, read up on that)

did you try the radio in car, parked say across town.?

did you try all stations

are you like 1 block away from an AM radio station, overloading yours.

AM radios are basically noise making radios., that is why FM was invented to stop that noise, (i cant hear it so.........?????)

are you listening to far away stations, this is normal

in fact you might hear 2 stations on same channel (freq)

and they will beat against each other.

on case of is in S.Calif where your station is clobbered by high power mexican stations 50,000 watts. strong.

and worse a night, does it get better in the day?



here is my advice, many AM stations have a rebroadcast on FM.

go there and listen. (use SAT radio?)

AM radio is subject to vast sources of noise.

ignition noise., high voltage power transmission line noise.

machinery noises, (electric)

or even illegal transmitters in your hood.



many new cars the AM radio is junk, they use this very cheap

chip inside that does this very poorly, but allows them to say

it has AM. ( for $1 cost)

the FM side is 10x better, or more. move up to FM like we all did back in 1967. (i used to build and sell converters back then)





answering for , all other modes work perfect, but AM radio..

I have an older onkyo integra (TX-870) which pop when I change stations, then no sound. Need to turn off and begin again. Can this be fixed or should I purchase a new 2 channel sys?

Hi, It sounds like you are listening F.M. radio and the F.M. muting button is engaged ( as well it should be-otherwise you will have static between the stations ) sometimes there is almost a "THUMP" sound when you switch stations-this is caused by the receivers P.L.L. circuitry losing then locking in on stations, if you do not lower the system volume you will amost assuredly cause an overload of your final drivers, that's why it will come back on when turned off-it has reset. Turning off fm muting will get rid of the "POPPING" noise-it will however leave you with unbearable static which in turn should cause you to lower volume momentarily eliminating the need to constantly turn off the receiver. Thank for asking FixYa, I hope this helps, let me know how I did or if I can be of more assistance, good luck Prodzilla

How do I preset the tuner for radio stations. I've never had a problem doing this with any other stereo. But what I think should work isn't!

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.

Poor cound quality

does the XM use a radio station for recieving the sound or is it wired in to the vehicle. if you have to set a radio station so you can use the XM then what you can do it set the station to some other channel. it maybe to close to a real radio station or the frequency it to weak and you'll need a stronger signal

Poor FM reception

The Phone must be on.
The SIM card must be a valid one.
The station you listen to and the network operator you use, must support the service.
The headset or enhancement needs to be attached to your phone. for the FM radio to function properly, it's an aerial as well as a headset.
Therefor if you are in a poor reception area for making/receiving calls it will also affect the radio signal.
