Re: [IRCA] TPs for 24Aug09: DU all the way (but late)
Allow a guy from America's heartland to chime in about how beneficial
outside antennas are for DX like this. These outside flag type antennas are
more directive than loops. While they don't have big side nulls like a loop,
they have a large wide back null. Very importantly, IMHO, they have a
vertical pattern that favors lower angle DX. As a result, many DXers get
distant DX better on outside flag type antennas rather than inside loops.
Of note is that with the Monday mowing done here I put down a Phased BOG
System aimed WSW for DU's ..355 ft // 208 ft. The longer one gets close to
the edge of my house, but isn't all that noisy. I think I could add about 30
to 35 feet more until I run outta room.
Of note during tonite SSS DX and into the early eve are 3 new ones, all from
that direction.
I have enough directivity to pull KBOA 1540 MO (what are they doing on at
night?) thru 50 KW super pest KXEL.
Phasing is a huge help as I basically don't have to worry about back end qrm
from anything except super locals, although on strong pests a little
retweaking can be needed from time to time.
As an example, Arizona's La Raza is in there on 1210 with WPHT phased down.
It seems KGYN has actually switched to night rig tonite as there's barely a
trace of them however, SD came out of no where just after 10 CDT with some
Twins show (they run day rig for sports sometimes)
Anyhow..it seems this antenna setup should be ideal for DU's ..I hope some
come in.
re 612...they've put some strong carriers in here before, but WMT IBOC can
be enough to ruin them.

Missed the boat today, getting up not until 13:24. The DUs must have

so far I've heard them this year! Weak audio still on 639 (but still as
strong a carrier as Brisbane). Audio on 531, 576, (both weak), 585
(music at 13:27 at 7), 594, 702 (both weak), 738 (very good RFO at
13:29), 747 (DU), 756, 774 (also DU...all 3 weak at 13:31), 801 (pretty
strong audio with music at 13:32 on S wire), 846, 963 (both weak). Now
up to the top of the X-band:
Weak audio on 1701 with at least 3 almost equal carriers noted and weak
audio), 1656 with a decent carrier and almost audio (at 13:37),
Hi Walt.
I just don't get this. You get audio booming in but, listening at the
same time, I only get carriers. We're not that far apart and my loop was
oriented for Australia.
Is this typical for MW or am I in some RF dead zone? That comparison of
simultaneous Perseus LW recordings that we did gave almost identical
results.

Brian, I'm very glad that you're on board with the Victoria DX team.
Several factors to consider:
1/ Location is everything. I'm only a couple blocks from the ocean.
This makes a huge difference. You can test this yourself. I've done it
on a number of occasions. I chose Cook Street driving down towards the
waterfront. Tune into 1610....there's a very weak TIS from Port Angeles
(it's harder to hear now with the Hindi 1600 station, though). As you
drive down Cook St, one will see a big rise in signal strength from the
flea powered station across the Strait. This is the ocean enhancement
that is very well known. There's a huge difference even a few miles
inland. That's why so many (most) DX sites around the world are on the
ocean!
2/ Antenna: I have some pretty big large diameter corner fed (see Bruce
Conti's website for more details) loops. My best DU one is a good 50 to
60' high and some 75' or so horizontal...lots of gain from that puppy.
The W array is only a little smaller. In most circumstances, it far
surpasses the ALA 100, and even that one, as good as it is, still has a
diameter around 40 or more feet.
3/ Just keep on trying. For several years now, I've started in mid to
late August and listened almost every morning from about 30 minutes before
sunrise to a few minutes past. It pays off as you get to know the
frequencies. Keep the PAL list handy as it's invaluable to look up who
the stations may be.
....Walt.
