Thanks RHF. I am looking for other users' experience. My unit comes
from Radio Labs, with the filter upgrade (their so-called, "Clearmod"
modification).
The difference when I switch from AM wide to narrow is almost always
inaudible and, for all practical purposes, does not make any
difference without detuning the radio
in slow mode. I wonder if owners of the stock radio experience the
same.
(The Radio Labs people think this is the way the radio is supposed to
work, which I found puzzling and surprising)

I have owned two Sangeans before.An ATS 909 and another Sangean that was
AM/FM/TV and Weather.I sent them back to C Crane because they were Crap!

This may be more of a function of the AM station's transmitter. Try
tuning off by 1 KHz so you get some sideband splatter. Can you hear
cymbals and sibilance, or do you hear crackling and popping? If it's the
latter, the station isn't transmitting any highs. See if the bandwidth
selector makes a difference while off tuned a little.

Is there any reason they did not furnish any actual numbers/
specifications ? Their website mentions something like a 'processor
filter'(?) . This sounds sort of evasive as far as I'm concerned . And
even Sangean doesn't have much information about the static or dynamic
bandwih measurements . They must be hiding something .

RK,

If you have a Very W-I-D-E 'Wide' IF Filter +8 kHz
and a not-so-wide 'Wide' IF Filter ~4 kHz you may
NOT hear or detect too much difference between the
two when it comes to AM-Mode Radio Reception.

However, If you have a Standard 'Wide' IF Filter
~5 kHz and a Narrow IF Filter -3 kHz you may well
Hear a/r Detect some real difference between the
two when it comes to AM-Mode Radio Reception.

What "kHz" and "Shape Factor" Rad-Labs 'claim'
for their Wide and Narrow IF Filter in the
Mod'ed Sangean ATS-909X Radio ?

Hi Dave,

I have tried that and, as I said above, without detuning you would
never know there is a different filter in there, but one should hear a
difference when you switch
from wide to narrow, without detuning. According to Radio Labs, they
have used filter bandwidths of 4.5 KHz and 2 KHz for wide and narrow.
A 2 KHz filter should cripple audio fidelity noticeably (and reduce
interference), but I am hearing no difference. I have had two other
people listen independently and they say the same, so it is not just
my ears. I have now read a couple of reviews elsewhere that indicate
the bandwidth switch does very little (including the guys at Universal
Radio, whom I telephoned), so it looks like a flaw this radio has,
including the modified version.

Hi RHF,

Radio Labs claims they have used 4.5 KHz for wide and 2 KHz for
narrow. As I said in my response to Dave, one should be able to hear
the difference between these pretty easily (for reference, my Drake
SW8 has 6, 4 and 2.4 KHz bandwidths, and one can hear the difference
between all three pretty well, especially in going from the middle to
the lowest bandwidth because the narrowest filter muffles the audio
distinctly). I just wanted to hear about other users' experience,
wether they have the stock or modified radio.
Thanks for your reply.

I think that you need to get your money returned.
