Can you say HD Radio? C'mon it's not too many syllables so give it a
try.

David - Please Re-Read Your Original Post
-and- Don't Read Anything In To It :

"KNX 1070 exhibits severe motorboating at night"

"Apparently the selective fading bug manifests during
very mild fades, unnoticeable before 9-14, but very
prominent and distracting since."

"I'm about 40 or so miles from the transmitter and the
night signal is definitely compromised."

Point of Fact - The Word "IBOC" does not appear in it at all.

* The Words 'motorboating' , 'selective fading' and 'mild fades'
are genearlly considered Analog Radio Terms.

* Digital "Drop-Out" would be an IBOC {Digital} Radio Term.

David - I never knew that your had an IBOC AM/MW Radio
to clearly make a judgement as to where it was the IBOC
Digital Signal that was the Problem with your AM/MW
'Analog' Radio reception.

David - I will give you the Point that you can hear Digital Hash
on your Analog AM/MW Radios that is Attributed to IBOC.
-but- To Attribute : 'motorboating' , 'selective fading' and
'mild fades' to IBOC is a stretch - imho.

David -Question- Do You Own an IBOC AM/MW Radio ?

FWIW - This "Tilda Boy" is Paying Attention.

I suppose I can try KNX this morning, but I don't see any reason for
IBOC to cause motorboating. Granted IBOC sucks in many other ways, but
it should not have such an effect on the analog signal.

M...Sushi,

1 - It may be that there is a 'Predictable Point' {Distance from
the Transmitter} and specific Time-of-Day when the Radio
Stations Analog Signal and it's Digital Signal cause a phase
mixing product that 'appears to be' {sounds like} what is
classically called 'motorboating'.

-Or- it may be the Radio Stations own Analog Signal with the
Digital Signal of one or more of the Adjacent Channels Radio
Station; that is 'causing' this audio effect.

The 'Cause' May Be Unknown - But What You "Hear" Is Real.

2 - Also I am hearing more and more of what we use to call
Automotive Engine {Ingition} Noise {at very High RPM} with
the Radi-Osophy HD-100 Radio.

When I first got this "HD" Radio this Noise was not as
noticeable -but- now it is the 'preponderant' sound across
the AM/MW Band except when there is a Clean and Clear
Analog AM/MW Radio Station to listen to on any given
Frequency.

-NOTE- This HD Radio "Noise" Background is so strong
that IMHO most 2nd and 3rd Generation "HD" Radios
should have a Squelch Knob to quiet-out this Noise so
that a Radio Listener only has to hear those 'local'
AM/MW Radio Stations with a Clean and Clear Signal :
Be it Analog or Digital.

It's part of the IBOC signal. If you have selectable single sideband
listen to any HD AM station, one sideband only; you'll hear it quite
clearly. It's a warbling signal at approx. 400 Hz.

Yes, I didn't understand you were using an IBOC radio. I have no
experience with one, other than trying to play with one at Fry's and
not getting it to work.


I notice that some of the IBOC hash does reach the analog channel,
even using a very selective filter. That is, the noise floor of the
analog signal is raised a bit. This is noticeable on very clean AM

M...Sushi,

The Radi-Osophy HD-100 Radio was functioning in the
Analogy Mode. Had a GE Superadio III sitting next to
it and basically heard the same thing on it.

It just may be that I am at the 'right distance' from the
Radio Station's Transmitter where It's Analog and Digital
Signals 'Interact' and cause the sound effect heard.

-Or- More likely it is the Analog Signal of One Radio
Station being Trashed by the Digital Side Band of an
Adjacent Channel's Radio Station. Again being at the
'right-distance' to where the two Signals 'Interact' and
cause the sound effect heard.

M... Sushi,

I can understand that yours was a valid listening
experience; and please accept that mine too was
a valid listening experience : After all that is part
the varied nature of radio wave propagation; and
the fact that while we were both about 400 Miles
from the Transmitter; we were also 120 Miles
apart. {Two Different RF Environments}

the AM/MW Band except when there is a Clean and Clear
Analog AM/MW Radio Station to listen to on any given
Frequency.


-NOTE- This HD Radio "Noise" Background is so strong
that IMHO most 2nd and 3rd Generation "HD" Radios
should have a Squelch Knob to quiet-out this Noise so
that a Radio Listener only has to hear those 'local'
AM/MW Radio Stations with a Clean and Clear Signal :
Be it Analog or Digital.

Yes, I didn't understand you were using an IBOC radio. I have no
experience with one, other than trying to play with one at Fry's and
not getting it to work.


I notice that some of the IBOC hash does reach the analog channel,
even using a very selective filter. That is, the noise floor of the
analog signal is raised a bit. This is noticeable on very clean AM
signals.


I don't know if anyone has tried but is it possible to remove some of
the IBOC hash on analogue signals by using DSP audio processing?

JB


The IBOC hash shows up in two manners. One is due to the finite slope
of the analog IF. Essentially, IBOC sits in the guard band. [Of
course, the guardband is now "quaint", dating back to the days when
the FCC cared about protecting signals. ] Given how AM demod works,
this shows up as high frequency hiss. Some of the digital hash falls
into the analog channel. It sounds like noise right in the voice band,
degrading the analog signal. There is no linear solution to get rid of
this noise.

Most stations are processing even the analog signal digitally, anyway. But
HD processing is generally done separately, to preserve more dynamic range
among other things.

Audio processing not the issue. The issue is the HD side bands screwing
up the analog reception. The noise for analog reception varies depending
on what radio you use to receive the signal.

For example I can't use the sync function on my Sony 7600G for KKGO and
KNX unless I want to hear a a low frequency buzzing in the background.
This was not an issue until they started the night time HD broadcasting
where I would want to use sync.

On the R8B and RX340 I can use sync but not side band selectable sync
unless I want to hear hiss in the background. Things will continue to
get worse the more digital mode is allowed to be used.

Most consumer radios have no issue; when you use an RX340 for a purpose for
which it was not designed, of course it sounds bad. Most listeners do not

The FCC did not take your reception of either station into consideration,
as, unless you live right on the ocean, you are outside the contours that

How much more can digital (HD) be allowed to use? It is authorized 24/7 for
AM and FM in the US, and I do not believe that there were more than 24 hours
in the day.

The IBOC sidebands would be completely audible on any receiver except
for the fact that the upper sideband and the lower sideband are 180
degrees out of phase with each other. Any asymmetry in the i.f.
passband (like selectable sideband reception) or in the propagated
signal (e.g selective fading) will upset the cancellation and the hash
and the warble will be heard.

Since I live close to the beach I get the best reception but inland

There are perhaps 250 stations in the top 100 markets that warrant use of
HD; the rest are not viable full market signals. And, in that fact, is the
problem with AM today... The better signals were licensed back from the 20's
into the 30's, moved a bit in '28 and after NARBA, but designed to cover
existing 70 to 80 year back population areas. Many growth areas have no good
AMs, many AMs have been outgrown by urban and suburban sprawl, and today's
noise levels all contribute to make most AMs poor HD candidates. The longer
term survival of AM is certainly in doubt when many major markets have less
than 10% of all listening to that band, and most of that in definitely
"senior" demographics.


The digital side bands could be

We can hope the power is eventually raised; on FM there have been studies of
raising the digital signal by as much as 10 db.

Same here. We have one AM station that sucks, and 1 FM station (a

No, it is actually not. You are perhaps missing the point that radio markets
are not single cities or even counties. Chicago is an 11 county metro, for
example. Very few signals cover it all. Only a couple get any significant
listening outside the metro, either... despite pretty good coductivity
there.

So there are really only a handful of staitons by day, on AM, that cover
adequately outside their radio market. And at night, there are even fewer
due to interference, directionality, and the fact that AM is only listened
to lightly at night demonstrates this.

The number is basically the 25 former 1-As, plus a handful of the old 1-Bs.
No former regionals get any really useful skywave, as the channels are too
crowded. And some of the 1-As are chewed up at night by other stations, like
KFI and KNX do to the East of the LA market.

AM listenership in the US and its age level. Within th enext decade, it

The decline of AM listening is mostly a function of age. The band "average
age" increases by 1 year every 18 months, nationally, and there are two
whole rated generations that for all practical purposes don't use AM at all
or only for some special occurrence. I steadfastly predict that Americans
will continue to age one year each 12 months, so there will be ongoing
ageing of AM listeners until the band is totally unprofitable. This will be
hastened by the current "we already read the tea leaves" move of many AM
news talk operators to transfer the format to FM and put the AM to some
other niche use until it no longer produces anything.

care about anything except the strongest groundwave coverage areas.



It will expand to the remaining good signals and to smaller markets... if
AM
is even around that long.


That is your flawed theory and you don't care do you.


Do a nice little straight line history and project into the future the total
AM listenership in the US and its age level. Within th enext decade, it will
be almost entirely over 55, and down to about 6% to 7% of all radio
listening.


Don't look now, but Tardo's website resume is changing again....it's
like a damned chameleon.

One would be enough but the number is a lot more than 25 to 30.


No, it is actually not. You are perhaps missing the point that radio markets
are not single cities or even counties. Chicago is an 11 county metro, for
example. Very few signals cover it all. Only a couple get any significant
listening outside the metro, either... despite pretty good coductivity
there.

So there are really only a handful of staitons by day, on AM, that cover
adequately outside their radio market. And at night, there are even fewer
due to interference, directionality, and the fact that AM is only listened
to lightly at night demonstrates this.

The number is basically the 25 former 1-As, plus a handful of the old 1-Bs.
No former regionals get any really useful skywave, as the channels are too
crowded. And some of the 1-As are chewed up at night by other stations, like
KFI and KNX do to the East of the LA market.

The only straight line I see is the HD driving listeners away evenings.
Using statistics to predict the future is foolhardy at best. You don't
know the future.


The decline of AM listening is mostly a function of age. The band "average
age" increases by 1 year every 18 months, nationally, and there are two
whole rated generations that for all practical purposes don't use AM at all
or only for some special occurrence. I steadfastly predict that Americans
will continue to age one year each 12 months, so there will be ongoing
ageing of AM listeners until the band is totally unprofitable. This will be
hastened by the current "we already read the tea leaves" move of many AM
news talk operators to transfer the format to FM and put the AM to some
other niche use until it no longer produces anything.


Instead of posting this crap, you'd better start altering your web
resume some more. Quick!

Snip

You are full of crap. KFI and KNX come in just fine here at night. I
also regularly listen to KKOH out of Nevada, KOGO San Diego, KGO in San
Francisco to name a few. I'm beginning to think you don't live in LA
when you post this crap. They all come in well on a portable radio I
hold in my hand so drop the jealousy act over my table top radios.

You do not seem to know what can be picked up on the West coast at all.
You seem to get your information from the Internet instead of actually
listening to a radio. You are a real nut job pretender. How can you not
know about the reception I get if you live in LA? I can only conclude
you are full of crap and that you don't live in LA or anywhere on the
West coast.

Audio processing not the issue. The issue is the HD side bands screwing
up the analog reception. The noise for analog reception varies depending
on what radio you use to receive the signal.


Most consumer radios have no issue; when you use an RX340 for a purpose for
which it was not designed, of course it sounds bad. Most listeners do not
have $5000 radios... most DXers don't either.



For example I can't use the sync function on my Sony 7600G for KKGO and
KNX unless I want to hear a a low frequency buzzing in the background.
This was not an issue until they started the night time HD broadcasting
where I would want to use sync.


The FCC did not take your reception of either station into consideration,
as, unless you live right on the ocean, you are outside the contours that
are going to get any protection these days.

On the R8B and RX340 I can use sync but not side band selectable sync
unless I want to hear hiss in the background. Things will continue to
get worse the more digital mode is allowed to be used.



- How much more can digital (HD) be allowed to use?
- It is authorized 24/7 for AM and FM in the US, and
- I do not believe that there were more than 24 hours
- in the day.

d'Eduardo another evasive answer :

More AM/MW Radio changing over to IBOC.

Higher Digital Signal Outpust from 1% to 2% to 4% to to to

Yeah, that more than 24 hours in one day thing is something you've not tried to

Right. I said there were a handful of stations that get any kind of regional
coverarage. KFI and KNX are licensed within the market you live in, although
you are in an area outside the radio metro, but inside the TV metro
(marketing terms like MSA and DMA were set up precisely so advertisers would
know where the influence of a market's stations extends to... it's not
arbitrary.... it is based on listening) where the signals may be receivable,
but few people listen.

KOGO is probably receivable as you are near the coast. I have no usable
night signal in Glendale, as 600 is very congested inland. 780 and 810 are
former 1 B clears.

You have proven my case. Many 1 Bs shoot out over the water, but the As and
usable B's combined are not even 1% of all the radio stations in the US, and
none of them has registered skywave based listening in ratings for many,
mnay years... decades perhaps.

All we are looking at here is whether the FCC and the broadcast industry did
the right thing. A sacrifice of a quantity of listening so small it is
statistically not quantifiable looks to many to be a fair price to try to
move AM to digital and to try to "reinvent" it. I happen to think AM is too
dead to save in the long run, but standing in the way of perhaps its only
chance to survive is also not appropriate.

You do not seem to know what can be picked up on the West coast at all.
You seem to get your information from the Internet instead of actually
listening to a radio.


I can get Kota Kinabalu many mornings, but that is no indication that anyone
else in the US is listening to it. My point... what I have apparently failed
to convey to you, is that reception of night skywave signals is not how
99.999% of people want to hear radio. The levels of such reception are so
low that they do not register in radio ratings, where every listening
incident is captured, including distant stations, in the current system.

You are a real nut job pretender. How can you not
know about the reception I get if you live in LA? I can only conclude
you are full of crap and that you don't live in LA or anywhere on the
West coast.


The fact is that many LA stations are unusable to me, let alone distant
ones. The noise level is so extreme that anything but a huge signal is not
worth listening to. You are talking about a theoretical ability to pick up a
station and I am talking about what people actually do when they listen to
the radio.

Our KTNQ, a 50 kw AM, of which a decade ago I was program director, did not
have a usable night signal much of the time where I lived in Toluca Lake; it
has no consistently usable signal in Orange County, either. And guess what:
we got no diary mentions in those areas, either. Listeners don't seek out
signals that sound bad.
