Any owners of this new radio here?
I am wondering if you are hearing any (audible) difference when you
switch between the wide and narrow bandwidth settings in AM mode.

Thanks for your answers.

Hello Ramon,

I have one at hand (about 8 years old I believe) and changing the
narrow/wide switch changes the RF bandwidth on LW, AM and SW. Changing
to narrow, reduces the "HF" part of the audio spectrum (so the tone
changes).

You may check the operation when listening to a relative weak station
adjacent to a stronger one. When changing to wide, you may experience
more interference from the stronger station.

With kind regards,

Thanks Wim. Are you talking about the 909? I am referring to the
909x, which was released within the last six months or so.

Whoops, I was talking about the 909, I missed the "x".

Hello Ramon,

Are you sure you have the channel spacing (9/10 kHz) set correctly for
AM broadcast band. If you are living in Europe, it should be 9 kHz
mostly. When a station isn't tuned correctly, changing the narrow/
wide switch has little to no effect.

With kind regards,

Hello Ramon,

This will definitely improve reception quality. Does this solve the
narrow/wide problem also?

No. The problem I am experiencing is that the narrow/wide bandwidth
switch does not cause any difference in audio quality and I want to
know if other users are experiencing the same. Thanks Wim.

Hello Ramon,

I hope some other people will add their experience. In my opinion, the
audio quality should change, so there may be something wrong with the
unit. If it is on wide, you will definitely experience adjacent
channel/frequency interference problems, especially when listening to
crowded parts of the SW spectrum.

With kind regards,

Here's a short review of the 909X although no mention of the bandwidth
switch:
