Jim, I said the same thing in the ARRL 160 contest. I heard DPM loud
and clear and called my head off...to no avail. And he wasnt coming
back to anyone. Assumed his QRN/M problems must be monumental.
But this time he came back on the third call. Go figure.

Message-ID:
Content-Type: text/plain; charset=UTF-8
Fri night rates in Ohio were below average but open to EU. Sat night
was slow with few signals as the night progressed, and 51 dupes. :<
My 3830 summary:
W3HKK: 18:45 hrs OTA 694 Q's ( plus another 51 dupes (6.9%) that dont
count of course) =57 Sections + 36 DX entities - Score: 186,744 pts.
(
the 4th highest score out of my seven CQWW160CW log submissions.)
Struggled to achieve a contest rate of 35 Q's/hr, with a high rated
of
108/HR early on Friday night.
===================================================================
STATION: IC7610 - Acom 1000 amp - N1MM+ Logging software - cw buddy
memory keyer/memory/real time keyboard supplementing the 8 cw
memories
in the 7610.
TX ANTENNA: No radials! This year I failed to lay out my 26 x 100 ft
radial system before the wx turned too cold to do so. So I was
running
700w into a 1/4 wave 160m INV-L with a vertical leg of 52 ft, and the
78 ft of wire sloping down to the E, ending about 15 ft above ground.
The only RF ground for the INV-L was a single 8 ft copper clad steel
ground rod dating to 2009, plus of course the earth beneath it. A 50
ft black walnut tree was my antenna support. Ohio loam conductivity
must be pretty good!
That means the L puts out a slightly stronger signal to the W. And as
usual, I have very good results towards the US West Coast, working
many CA (19) & AZ(8) stations in particular. .
RX ANTENNA: SAL 30 ( four short delta loops 30 ft tall,
electronically rotatable in 8 directions.)
CONTEST CATEGORY: Single Op - High Power ( 700w) - Assisted
CONDITIONS: FRIDAY night was about average, with some decent openings
into EU. And many strong US sigs, but not as many of them. ie My best
actual hourly rate in 2022 was about 65% of my Personal Record Year
of
2020; and my score was also about 65% of my Personal Best Year of
2020
- which happened to be at the solar minimum. My 2022 average contest
rate ( total Q's divided by total hours OTA) was a humbling 35/hour
due eto the very slow 2nd night. It was hard work to say the least.
SATURDAY night had MUCH slower rates, and far fewer - and weaker -
sigs. Required a lot of searching and pouncing to separate fresh meat
from stations already in the log. But still, I was called 51 times by
stations who had already worked me. Since its always faster to just
work the dupes than try to explain that theyre a dupe, you just work
them and move on. At one stretch Sun morning, almost 50% of my CQ
replies were dupes. So I switched to S&P.
As sigs thinned out, many were just above the noise, requiring agile
fingers on the eight direction SAL30 RX antenna, switching from W to
E, N to S, and directions in between. The 20 db F/B often made all
the
difference.
SS CYCLE: : With the bottom of the SS cycle now history, Ole Sol was
again throwing out particles that tended to mask Top Band signals
passing through the ionosphere, by adding 20 dB or more attenuation.
DX: Hams in the northern latitudes complained about poor to
nonexistant conditions this year. I heard no Scandanavian stations,
and few German stations among the central, eastern and southern
European stations coming through.
I saw a few JA spots but heard nothing. And it took two days of
trying to work KL7SB, the Alaska contest station, and even then they
were barely above the noise floor when I worked them Sun morning
around 6 am. Only two KH6 stations got in the log, also with very
weak
signals. And the ZL and VK spots were few and far between - again
with
none heard in Ohio.
COVID 19: continued to quite adversely affect the number of
DXpeditions OTA from places like Africa, the Pacific, S.A., and C. A.
etc.
PS EARLY RETURNS: W3HKK LOG PLACEMENT IN 3830 - AS OF 9:30AM TODAY

After? putting down 3600 yard staples to install 55 radials 130 ft
for my 100 ft wire vertical with a 30 ft L I was ready for the 160
test.? For RX I used an SAL-30 which performed well at my old QTH in
KH6.
The only other V3 station was V31MA who has an excellent location
close to the water with a great take off to W/K and EU, but ran LP, so
it was hard to compare on the RBN.? I'm curious how the antenna
performed as i finished the radials right before the contest and
really didn't have a chance to check it out on the air.? I had quite a
few EU and many JAs that were there but I couldn't copy them as they
were in the mud.
Any comments on the signal/condx would be appreciated.

I worked you before and during the contest.? You were 5NN :-)
Don't ask what you really were, but I have a really modest station,
so you were
doing something right.? TS-890, KPA500 and an inverted-L, 55 ft
vertical, the
rest horizontal (only 18 on ground radials).? I receive on the TX
antenna and
still hear better than I get out.? I just did a low-key S&P
operation.? 107 Qs,
six JA, one UA0, one BY, two XE, two HI, one ZF and you.
I spent most of my time playing Band/Slot Bingo with TO6S.? If the

Bill,
I was not QRV this w/e.dealing with high winds, snow, and life.
Any reports you get will be anecdotal, but...if you go to this link:
http://beta.reversebeacon.net/analysis/
/>
punch in the date you are interested in (I used Jan 31rst) and then
punch in
V31XX, then add V31MA
you can see in graphical gory detail how they did at individual
skimmers all
around the world, spot by spot.
I'd cut and paste some graphs here, but the reflector won't allow
graphics
or attachments.
I selected 4 or 5 different skimmers (one at a time..and only one
date at a
time)
Seems they very much held their own with operating at a 12dB or
whatever
deficit against you.
Let us know what you think is going on.

Hi Bill,
You should still be able to compare yourself to V31MA using the RBN
data.
Just find out how much power V31MA was running and compare it with
your
power level in units of dB. Then you can use the RBN data to compare
your
signal to V31MA as long as you subtract the dB difference in power
from the
V31MA data.
Hope that makes sense.

Hi Bill,
I misunderstood, it looks like V31MA was running low power, so you
would
have to subtract off the difference in dB from your RBN data to see
how it
compares with V31MA.

While listening on your RX ant try opening and shorting the feedline
to your TX antenna -I bet there is a big change in RX signal and F/B
on a given station will change .
My model of a 2 el active rx array pattern when I change the
impedance presented to the center of my inv vee shows that if that
impedance at center of the inv vee is not above 500 ohms -it will
seriously destroy the two el pattern. ( For quick look I did it for
real part -have not looked at pattern degradation vs reactive loads
since my feedline to the inv vee happens to be a half wave long .)

I've laid down a radial under each side of the loops, but while it

some directivity on high-end broadcast stations, 160M directivity is
limited to nil, signal strengths are rarely better than my
inverted-L,
and the adjusting the termination seems to make very little
difference.
Any hints?

Colleagues,
I have to live with CC&R homeowner restrictions. I plan to erect a
disguise
wire antenna around the perimeter of my roof; total length will be
about
190 feet. Elevation will be about 20 feet above ground and will be
fed with
150 ohm twin lead.*
My question is: Should this be a continuous loop or should the point
opposed the feedline be terminated with an insulator, thus giving two
95-foot legs?

* 150 ohm twin lead: It consists of two parallel lengths of 75 ohm TV
coax
with the copper braids soldered together at each end; the inner
conductors
act as a parallel feedline. See the ARRL Antenna Book, August 2000
edition,
for details.

like he is unable to do something about it so the rest

Subject: Topband: New 9 circle PCB with CMCs
Message-ID:
Content-Type: text/plain; charset=utf-8
Hello fellow DXers,
Today I uploaded a YouTube video describing my new 9 circle combiner
board PCB design that has small Murata SMD CMCs on each RG-6 feedline.
I include PCB file links to download in both KiCad format or a zipped
Gerber folder if you want to build your own. A BOM and an image of the
schematic is included as well.
This is the 9-circle array that was designed by John W1FV.
I review why we need these CMCs, I talk about these small Murata
chokes and some VNA tests I did and how these same units can be used
as Magic-T?s.
The new design also has a pin-out for the vcc and relay control
lines, has the option for gas discharge tubes on the vcc and control
lines, and the board has a slightly larger footprint than my previous
designs so its its easier to access the F-connecters for field
installation.
The evaluation is still on-going at VE6WZ, but the board tested very
well in the shop with the VNA, and I used it this weekend for the CQWW
160m test and it performed well.
I know there are many that ?don?t like? to watch a video, and I may
build a PDF document, but in my ?prior life?, all I did was make
technical/ scientific documents and I?d rather not do that anymore.
It?s much easier to say things quickly in a video. If a picture is
worth a 1,000 words, then a video is worth a million.
