And 'what' do you attribute this too . . . ~ RHF

- IBOC. Try to pay attention Tilda Boy.

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

"KNX 1070 exhibits severemotorboatingat 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

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.

david- now go enjoy your radios ~ RHF

David,

I apologize - I am now Hearing what you described
as "Motorboating" on many of the "HD" Stations in
the Early Morning at about 7 AM.

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.- Hide quoted text -

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.
