Re: [IRCA] Michigan DU's, Sept.20th

[Neil Kazaross <neilkaz58@xxxxxxxxx>]

T storm QRN  have been a bother here in IL with the now near record warmth.
Re: 882 I get the same two carriers, but never audio past KHAC USB slop and
WLS slop. Likely AUS/NZ mix. Perhaps you can do better, being further from
both KHAC and WLS.

Re: 1098 hopefully you can get it better soon, and tell that the man is
speaking an island-type lang. I think this usually their s/off.

Re: 828  3GI gets out for 10 kW. I've had carriers for years. Sometimes
WCCO has faded down by then. Last season I managed some audio, same as
podcast. Another possibility for me is at month's end or into early Oct
where in good cx ABC stns. hang around 'til 1200 UTC and you can make out
their trumpet fanfare into ABC nx.

I wonder what 693 is? So far no audio and here it is bothered by the
tragedy of WSCR IBOC.

Re: antenna experiments. The Double Flag is a good antenna for sunrise
DXing for DU's with good low angle pickup and 7 dB more signal (given the
same footprint) than the Double KAZ. However, the DFlag seems to have in
general 5 to 10 dB worse back null and while that doesn't harm me much at
sunrise, it is quite harmful to my DX any other time. So it is back to a
DKAZ for my west antenna and once I have it working like before, I will add
a second one staggered by about 30 feet south and 80 feet east and array
them. Modelling shows this is promising. I haven't any more room to array
them directly inline.
