[IRCA] ALA vs EWE patterns
It would be interesting to compare the pattern of a EWE and ALA. Since I
have installed the NE EWE, the dominant stations on so many frequencies
are different. During most of the day the weaker Portland stations are
non existant or if there very weak and buried. Here are a few examples:
FREQ SW EWE NE EWE
550 KOAC KARI/KOAC
610 KRTA KONA/CKYL
660 KXOR KAPS/CFFR
700 KGRV KXLX
740 KCBS CBX
760 ..... CFLD
770 KTTH KTTH/CHQR
790 KWIL/KWSW KGMI/CFCW
*800 KPDQ CKOR
920 KSHO KGTK/KXLY
930 KAGI KYAK/CJCA
960 KLAD KALE/CFAC
*970 KCMD KTTO/KCMD
*1010 KOOR CBR
1030 KDUN KMAS
*1040 KXPD CKST
1050 KORE KEYF/KBLE
*1080 KFXX KVNI/KFXX
*1150 KXMG KKNW/CKFR
and so on. The lobe of this new NE EWE is excellent. I am amazed how
well it works being so small (15X40X15). I know it is still Winter and
some of these stations will not be dominant come Summer, but the pattern
is pretty tight to wipe out stronger stations to the South. In reverse,
the SW EWE, when peaked correctly has also works as well.
One downside to this EWE is the lobe, which is a double edged sword,
as well as I get the weaker stations to the NE, I also get
Seattle/Vancouver/Calgary/Edmonton on about every channel at night and
some signals are like S9+20-40 DB!!! Also my weak locals are not as weak
now, with the NE lobe, it is aimed at KAST/KKEE-Astoria. KAST at 5.6
miles away is S9+50 DB now! KKEE 1230 is S9+45 DB. Fortunately both are
talk and splatter very little. But of course I can switch to the SW or
NW EWEs, or phase the stations. But along with a new lobe I get pretty
of pests too. Oh yes, Seatle & the Puget Sound to the NE.....KIRO 710
has an ERP at me of 86 KW already, so with the NE EWE, they are S9+25
days ans S9+40 at night. KJR-950 is another. At over 100+ miles, there
is still enough distance between me and the Puget Sound that is it not
too overwhelming though.
Since there is very little IBOC to the NE of here, the NE EWE does a
pretty good job on nulling stations to the S/SE that have IBOC like
Portland and that helps. KEX 1190 has IBOC, but with the NE EWE,
KLAY/KOFI 1180 come in fair during the day now. 1170 KPUG Bellingham
comes in like gangbusters.
Often when there is a weak opening for TAs, I can denote carriers or
weak audio on only the NE EWE. I wish I would have installed it earlier.
I had to go out and repeak the SW EWE yesterday as I could tell the
antenna did not have the good peaks/nulls. As I thought, the cows had
knocked the control off somehow. Even with the screening they seem to
get all it. So I put an old log in front of it now. I can still get at
it, but hopefully the cows wont. At least they are now chewing on the
control any longer. hi.
