Topband: ARRL 160M being heard

Gentlemen,
If you are not very close to zero beat, I will not hear you. A bit of
offset may be okay and even helpful but a good few stations are only
recognized by their key clicks. I use a 300 Hz note so imagine that I
only need you to be 20 Hz off the zero beat. I find the CWT feature of the
K3 a considerable help in a contest for getting close to the zero beat
frequency. You go a few hundred HZ off and forget being copied. The band
is going to be very crowded come the CQ 160M CW test at the end of January.
I find the selectivity a big help. We are all different.
Another reason why we are not heard is that receive antennas if good
may be very directional. If I beam to Europe or Asia then NA is not heard.
If I beam to the USA then quite possibly an EU station will not be heard.
For contesting I find the directivity of the Hi-Z full size 160M 8 Circle a
God send but I need to be conscious of this at all times. It may be a
help come the Stew Perry when my main interest is working W land.
Some of the EU complaints about not being heard by Ws during the ARRL
160M contest may be due to NA QRM but also due to the W using a RX antenna
pointed away from the EU.

I respectfully disagree with Don Kirk. My experience has been different. I
don't how many pileups I've broken quickly - where the station I'm trying to
work is operating simplex - by going split and transmitting a few Hz above
or below "zero beat". The operator at the other end is trying to copy a
callsign, and if everybody is "zero beat" it makes it very difficult to copy
anybody. Anything you can do to make your signal "stand out" or
differentiate it from the crowd makes it easier for the station you're
trying to work. (Also speeding up or slowing down a few WPM sometimes
helps.)
Someone taught me this a long time ago, and it works. He's worked a lot of
good DX in the last sixty (60) years or so.

Hi Trevor,
Besides your TX antenna, another issue I have observed over the years is the
importance of being as close to zero beat as possible. The modern HF radios
offer very narrow RX filtering options, and during very crowded band
conditions most of the stations are running very tight filters and I find
that if I'm off zero beat by much more than 100 hertz I'm often not heard.
I use a very old HF rig and run a 500 hertz filter, and found myself having
to continuously adjust my TX frequency until I popped into the passband of
the station I was trying to work (very difficult to zero beat my radio in
any kind of timely fashion). I finally installed an audio filter (Hi-Per
Mite) with 200 Hz bandwidth and this has basically fixed my problem (99.9
percent improvement).
Previously it was very frustrating hearing a station 20 dB over S9 that
could not hear me. I originally thought they were using an RX antenna not
pointed my direction, but most often I was just not in their RX passband.
Just another possibility.
73,

That's not going to work often during a contest. It depends on how crowded
is the band you stretch or narrow your passband. When a narrow filter is
set if you call 100 Hz away we won't hear you.
During a dxp the scenario is quite different, you're the alone, I normally
set, whenever is possible, the widest passband so I can hear anyone on the
split within 2,5 KHz, the brain does the rest.
Thanks for the last weekend ARRL contest QSOs.

Jose,
First thank you for the QSO.? You are one of the few Europeans I have worked
on
160 with my very modest station in southern Arizona and are a new one for
me.
I think the that the key here is "a few Hz" offset.? Of course 100 Hz is
more
than a few and would be too much for a receiving station with a 50 Hz filter
in
use.? I will just turn on XIT and dial in +/- 20 - 30 Hz.
As a practical matter in my case, I will in all likelihood not be heard in
any
pileup of central or east coast USA stations anyway.

Hi Marsh
I agree. This is a basic technique and I?ve used it for decades. While
stations butt heads on the ?zero beat? frequency I transmit 100 to 200 Hz
above and usually make the contact. During the ARRL 160 Meter contest
there were times I was transmitting 300 to 400 Hz high to make the
contact. If your station can project power than you can butt heads;
those of us that have more modest stations need to do things differently.
This technique works well for contests and DXpeditions (although
thankfully most dxps run split).
Running stations and using a very narrow filter is asking for problems. I
typically use 250 Hz and make sure my RIT is well oiled. If a station
successfully encroaches on my run frequency such that I have to go to (say)
a 100 Hz filter, I find another frequency ? there?s plenty of real-estate
on 160M.

I understand that I have to improve my RX antennas as currently I find the
TX antenna is better on RX that both of my current RX antennas, While I get
a good reduction in noise floor on the RX antenna's the DX just isn't
workable on them
The TX antenna is 55ft of Aluminum Tube It tapers from 2.25" to 1" at the
top, I have 2 top loading wires each 50ft long tied off to Tall trees in the
distance,
The ends of the top loading wires are approximately 45ft high, I'm using a
4" diameter coil double tapped to get Resonance and to match the feedline to
50ohms,
I have currently 48 radials mostly between 15-25m long, I hope to improve
this greatly in the spring before the grass starts to grow again,
RX antennas are a Wellbrook loop and a 450ft Beverage pointing NE for JA/OC
I need to put something up for NA and hope to do this over the holiday
period ready for CQ160 in the new year,
Thanks

This is the first major contest that I
have taken part in a while, at least to
the extent I actually put a real effort
into it. Its taken a bit to get back in
the game after my friend Pat became a SK
this year. That said, I almost matched my
score from two years ago when the band
conditions were for me, far better for DX
than this weekend.
I was running QRP with a less than ideal
antenna yet still managed 535 QSOs. It was
frustrating to hear so much DX and not be
able to have them hear me. I'm guessing I
must've heard at least 15 countries that I
didn't work. When running QRP on 160, you
have to go for low hanging fruit. I'm sure
it's the same for everyone.
I was grateful that there weren't any
storms happening locally this time and for
the most part bands were pretty quiet.
AMTRAK had its way with me at the Gray
lines what with commuter trains running at
that time but being a weekend made their
schedule a little easier.
One of the surprises was when K7RAT called
me Sunday Morning so at least my QRP
signals were getting up to Boring, Oregon.
The band must've been good because his
signals were truly marvelous here as well,
one of the loudest & cleanest signals on
the band and he heard me with no trouble.
If that was you at the helm, thank you
Tree for the multiplier!
Sunday morning at Gray line was really
something beautiful to see on the P3. 1/2
hour before there may have been 50-70
people CQing and then the waterfall became
a Kaleidoscope with the band packed with
people as tight as sardines up to 1875 or
so. It's obvious when the band changes and
the atmospheric noise is visualized as
color in motion, in two dimensions. If you
haven't seen the morning Gray line on a
waterfall during a 160 contest, you're
missing something interesting.
Hope all had fun.

Hi Trevor,
I looked at your QRZ.COM page and I'm concerned that your tower
and Yagis may be degrading the performance of your nearby 160
meter vertical. It can contribute unwanted nulls and unwanted
ground loss. What is the height of your tower to the top of your mast?
Small loop antennas ("magnetic loops") such as the Wellbrook are
great for nulling local RFI, but they're low performance receiving
antennas for DXers as you've discovered. Beverages are very
effective receiving antennas but their directivity will be degraded
by a nearby 160 meter vertical and perhaps your tower too.
Its will take a great deal of wire to improve your existing radial
system even marginally, perhaps four times more wire than in your
current radial system.

to the northern auroral zone.
I've made some extraordinary contacts in my 35years on topband during these

signals.? BD4WN was the loudest I'd ever heard him and JA3YBK was 10
over 9 at sunrise until 15 minutes past sunrise.? He was still solid 45
minutes after sunrise.? Sunday night, I heard the first EU Russian since
getting on TB almost three years ago.? I was looking forward to a great
post-contest Monday night and bang - the K index jumped up to 4 - just
like a few weeks before.? I heard no Asian signals this morning and so
far no EU on 160 tonight (Monday night).

I have also observed enhanced, and sometimes extraordinary, propagation at
the onset of disturbed conditions. A recent notable example was the LP QSO
with VK6VZ that I reported last month:
http://lists.contesting.com/pipermail/topband/2017-November/052869.html. At
the time of the QSO, the K index was 6.
However, disturbed conditions do not always bring enhanced propagation.
There is not a 1:1 correlation in my experience but it's worth checking the
band when severe geomagnetic conditions are imminent

Hi Bob
Do agree with your observations relative to prop enhancement on the upside
(beginning) of solar disturbances. Especially for we northern types close
to the northern auroral zone.
I've made some extraordinary contacts in my 35years on topband during these
situations.
Now if we could just have one fall on the days that stns like XW4ZW and the
BD/BG stns are active, hi/

It seems that several times, we have had big openings into Europe and Asia
from out here in Arizona and my hopes of having a great opening the next
night was ruined by a big geomagnetic storm. Last Saturday morning, the JAs
were quite weak here. Sunday morning, several Asians had good signals.
BD4WN was the loudest I'd ever heard him and JA3YBK was 10 over 9 at sunrise
until 15 minutes past sunrise. He was still solid 45 minutes after sunrise.
Sunday night, I heard the first EU Russian since getting on TB almost three
years ago. I was looking forward to a great post-contest Monday night and
bang - the K index jumped up to 4 - just like a few weeks before. I heard
no Asian signals this morning and so far no EU on 160 tonight (Monday
night).

I don't think it's just topband. I've observed exceptionally good
conditions right before a solar disturbance hits earth, on any and all
bands.
