Well Folks,
I see that WABC, WOR and WFAN 770, 710 and 660 are broadcasting IBOC at
7:30PM tonight. I like to BCB DX and I have found that nulling out the
IBOC sidebands is easy to do since they are weaker than the main signal.

Using my GE Superradio II I just turn the receiver to a null and perfect
copy +- 10khz. I am very close to New York City and the NJ Meadowlands
where the signals all originate and it is not too hard to get a null. As
signals pickup later into the evening from the skippers I have good copy.

Now for my formal DX setup using the Horizontal pennant antenna with the
DC null adjuster pointed towards New York I can very easily create deep
nulls on the IBOC sidebands both plus and minus. So for home listening and
DXing IBOC really does not seem to be a problem at night for me. For the
avid DX'er just build a pennant antenna or get a directional loop.

Driving cross country at night still has to be tried and I suspect that
may be a little trickier. I suggest giving it a try to see that the IBOC
signals do in fact null without to much difficulty.

RickaTTic,

OK - Please 'clarify' this for me
are you using this technique to :

DX the Analog AM/MW Radio Stations ?

-or- DX the "HD" AM/MW Radio Stations ?

And -if- the two Radio Satations are basically in the same
direction from your location - How does this help ?

Plus -if- you are within the Ground Wave of the Interfering
Radio Station - Again - How does this help ?


i want to know ~ RHF
