Bill, thanks for the QSO and the mult! But its hard to say re: your
new antenna. It should be a whopper for you, with 100 vertical ft, but
overall signals wee down, and I didnt hear a lot from CA SA or the
Carib. Probably partly due to COVID and part due to the increased
solar activity/D layer losses. (FYI My 1/4th wave INV-L is just 52 ft
vertical, but this year I failed to get my 26x100' radials rolled out
before the snow hit. So I was working against a single 8 ft ground
rod!! BUT it still brought me 700 Q's and 36 DX entities in below
average to poor conditions. DX sigs were all "down" this year. Even
the XE's lacked their usual booming sig strength here in OH. )

I did work both V31's, but on different nights which were like night
and day ( pun intended). I will say I heard you consistantly through
the contest, which is in itself impressive, but never especially
strong. Tho I suspect if cndx were truly good, youd have been much
louder.

All I can say is I wish I had 100 ft vertical leg on my INV-L!

 Message-ID:

 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

 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

 doing something right.? TS-890, KPA500 and an inverted-L, 55 ft

 six JA, one UA0, one BY, two XE, two HI, one ZF and you

 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 .)

 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.

 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.
