Try that statement at latitude 65.4N Roger, I can tell you that 
sunspots have a HUGE affect on TB propagation. And not in a positive way.


This season is a total bust so far, no DX heard at all. And 80m is

Re: Topband: Horrendous Local Noise

2021-11-12 Thread Peter Voelpel
I had a similar problem some years ago with an origin I could not find
myself.
Big noise on 80m of 9+20dB, about 60kHz wide and moving up and down the
band. 
No chance to DF it with everything conductive reradiating the noise
frequency.
Took our authorities almost 3 hours to find the source, the power supply of
a sat receiver 3km away!
That was radiating into the phone line which is not underground here and
distributing it all over the village.

Subject: Topband: Horrendous Local Noise

Well I haven't been able to come on 160m for over a week, as I suddenly had
the most horrendous noise all over the band, S9 + 30 dB, all day and night,
every day !

I have tracked down rogue equipment in neighbours' houses over the years,
just by using a small AM radio and DF-ing, using the null on the end of the
internal ferrite rod antenna to show me the direction (you just need 2
bearings). But going out in the street this noise was coming from everywhere
. . . got loads of different nulls in different directions, depending on
where I stood.

I figured it must be a major fault with the underground mains cables, arcing
somewhere. (we have 415V 3-phase running underground over here, and just one
phase tapped off to each house, which gives 240V against Neutral.)

I called out the company responsible for maintaining the cables, and they
arrived within an hour. But they could find nothing wrong (they agreed there
could be arcing underground, but said they didn't have any equipment to
detect where the fault might be - they just rely on the power going off to a
particular house!)

So on Wednesday I called OFCOM to report the problem (like your FCC in the
USA). I figured it would be hard to get them to come and investigate, and
even then it would take weeks. But they were actually very interested on the
phone, and I emailed them a Log on the Thursday morning. On Thursday
afternoon the guy responsible for the NE of England rang me, and said he was
away on holiday for 2 weeks on Monday, so he would try and juggle
appointments so he could come up on Friday afternoon!

Well he drove the 100 miles up here and arrived with a colleague about 2pm,
spent a while in the shack listening to the noise, and monitoring it on
their equipment connected to my Top Band dipole. After about 45 minutes they
both went out in the street, and an hour later they came back to say they
think they had tracked it down. 

It actually turned out to be a faulty piece of equipment in a house up the
street . . . but not radiating directly - it was sending these huge spikes
back down the Mains . . . and then I guess the wiring in all the houses
along the street was then re-radiating the noise (which is why I couldn't DF
it properly).

I was absolutely delighted ! So a big thank you to Alan and Tony from OFCOM
for coming and sorting my problem so very quickly . . . I really never
expected such amazing service.

NO, I don´t need any country


2.  Have you determined the best time of year, time of day, and band to see
if a station from that country is on?

NO


3. Have you searched the decodes daily for a station from that country?

NO, I don´t decode anything


4. After spending days hunting that DX, have you FINALLY managed to be there
when the propagation was favorable?

NO, I don´t hunt DX, just talk to them if they call me


5.  Have you then, after all that, called that DX and made the contact?

NO


If that does not qualify as ham radio, I’m not sure what does.

Will a 2-wire section like this always behave as a wide/fat conductor

Regards , Kenny K2KW


Just a guess:  I would think with 2 wires, you would be fairly
successful with getting good current sharing, as long as there
wasn't some unbalancing effect, say due to having the vertical
running along side a tower.

With 3 wires, there is some reason to think that the middle
wire wouldn't carry much current if the three wires were
in a plane.  OTOH, if they formed a triangular cross section,
then it would seem likely that current sharing would be good.
In general, you want to emulate a round conductor, as opposed
to a strap.  When straps are used to make inductors, the
current crowds to the edges.  Round conductors don't have
such edges, hence they have good current sharing.

I don't believe NEC is good for modeling this.  You have
to use a tool called "HOBBIES" if you want to do this.
K6OIK has written some articles about this tool.

Re: Topband: Morning (W6 time) opening to European Russian today at ~1300Z during ARRL contest

2019-12-09 Thread Peter Sundberg
You were a very good signal here Rick all the time you were in 
darkness. Unfortunately you never heard me and I know there were 
other callers as well from northern Europe :-)


Super signals from all over NA this past weekend. The band never died 
as long as there was darkness over the entire, or some part of the, 
continent. Interesting to note, after sunrise here at 65.4N stations 
from the east coast, who still were in complete darkness, got 
noticeable weaker while the mid west and west coast stations got 
stronger. This follows the trend I've seen befor.


The band was packed with NA signals, all the way up and above 1850 kHz.

Two types of QSB were predominant. The usual very slow QSB with nulls 
and peaks that last for more than a minute, and the very rapid QSB 
which takes signals in and out of the noise in 10 seconds or so. This 
was especially noticeable on KH6/KU1CW - in the morning hours my time 
very short but strong peaks, come noon and afternoon more or less 
solid copy all the way until sunrise in KH6.


It is always interesting to hear west coast NA working Asia while I 
am hearing both sides equally strong. The problem for me is that you 
guys in NA are predominantly (of course) listening with antennas 
pointing to Asia, so it is not easy to get a QSO with you at that 
time of day. Despite very good signals at this end.. but a bunch of 
us up north were indeed trying hard to get your attention.. :-)


Too many calls to mention who stood outover time. But looking at the 
most difficult path straight over the pole K7CW, N7ZG, N7DD, N2IC, 
W6AYC, N6RK, KH6/KU1CW, KL7FB plus the amazing signals all day from 
the potent VE6 crowd - VE6WZ, VE6WQ, VE6BBP. And K0RF, like a beacon 
at all times.


As I've said these are just a few calls picked out from all the 
stations heard over the weekend. I worked 55 of you, so not bad 
considering I was only on from early morning and I did not burn the 
any end of the candle in the middle of the night.


This weekend is pretty much on par with the way the band was in 2011. 
That's the year that I made it to 49 states worked, only missing MS. 
This Sunday morning I heard N4OGW in MS working mainly NA stations 
before he suddenly disappeared, ouch..! :-)


Let's hope these lovely band conditions continue well past The Stew 
and the CQ 160M CW !

I had the same problem with my K9AY loop. Despite being
in a wooded area that seemed to have very damp soil the
earth conductivity was poorer than I had expected.

I added eight short radials under the loops and that made a
huge improvement. I also added some cheap CATV ground
rods to tie the ends of the radials down.  Nulls are fairly
decent at present, but I may try adding some cheap chicken
wire under the loops for the heck of it, as an experiment.
My loops are near wire fencing for a field for a local horse
farm, and the tower and inverted L are about 40 and 60
feet, respectively, away.

I am not sure on the vintage of your loops, but the newer
versions have adjustable termination resistor choices...
I have read where others have found much better results
by changing the terminating resistor to match their own
soil conditions.  Unfortunately mine was a very early
product and only had a few fixed values that is not
remotely selectable.

I think I am blessed with a fairly quiet rural location,
since generally stations are equal on either
the K2AV system compared to the loops.

Re: Topband: Ground for K9AY Loop

2019-10-17 Thread Peter Bertini
I had a similar issue with my K9AY loop.  It was very non directive, even
with a short ground rod.  I added four ground
radials laid under the loops to the apex points where they met
the ground anchors.  That fixed the problem. I also added
four of those cheap TV ground rods at each corner and
tied the ends of the each radial to a rod.  Directivity is
superb now.

Re: Topband: Summer Update & a Surprise

2019-07-31 Thread Peter Sundberg
If we CW operators would all stay on a very tight frequency passband 
and call CQ every 15 seconds I bet there would be a lot of 
interesting things happening to us also. Especially if we do it 24/7 
or at least every hour that we are not asleep.


However, PC-automation has it's advantages, some are at work while 
working DX and others are gardening. Some even sit by the radio/PC 
and watch things happen :-)


Bottom line is, we need to activate our transmitters more and not 
just listen for others. A perfect example is Bill KH7XS who opens up 
almost any seemingly "dead" band to Europe, at any time, just by 
calling CQ for a while.

Subject: Topband: Summer Update & a Surprise

Hi Gang


It is mid summer here and E season on 6M has been fun to play with 
while 160m is pretty S L O W as it usually is.
On these pages there has been alot of chatter regarding FT8 - (which 
basically took over 6M DX'ing starting in July 2917 - all DX is now 
on 50.313 FT8 - which is why I had to adopt this mode in order to 
continue DX'ing on 6m).  It was either do that or give up operating 
on 6M during E season.
I do hope that CW continues to thrive on Topband - but this past 
season there was TONS of DX on FT8 and in my opinion LESS DX on CW 
than in prior years.   It is quite possible to work in JA on 160m 
from here on FT8 with 100w out - which would have been quite rare 
indeed on CW as I recall (I do not think I ever worked JA with 100w 
from here - but who knows?)
Today as I write this - I am listening to 28.074Mhz on a totally 
DEAD 10m band.  If I tune the entire CW portion and the whole SSB 
portion, there is NOTHING - repeat NOTHING there - no signals 
whatsoever to be found.
Yet on 28.074Mhz - I just worked a whole page of Europeans on FT8 - 
to my almost total INCREDULITY!!
I am not sure how I feel about all of this - but one thing is SURE - 
the DX world has changed - and there is no looking back.
I love CW on Topband and used to love CW on 6m - but that no longer 
xists  -so I do hope the 6m migration to FT8 does not repeat itself on Topband!

To all a good summer and CU on CW again starting in September.

Re: Topband: AM interference on 1840,

2019-05-20 Thread Peter Bertini
If the problem is related to receiver overload, than a trap at the BCB's
operating frequency will correct the problem.  Unless the problem is
related to a non-linear junction (rusty fence wire, etc.) generating local
IMD or harmonically related signals due to rectification.

If the problem is the actual presence of a harmonic radiating from the BCB
transmitter, than no amount of filtering at the ham's location will cure
the problem.  Using a receive filter on 1860 will attenuate both the
harmonic signal and desired amateur signals.

There can be advantages to having a high pass filter that limits BCB signal
levels, but it will not cure this problem.

The traps belong  at BCB transmitter site if it is a real harmonic..

If I had this problem I would explore using a noise cancelling system (MFJ
or one of the Russian eBay
kits) to try and null the direction the signal is coming
from.

Re: Topband: FCP versus loaded or "T" radialsradials,

2019-05-07 Thread Peter Bertini
I think Tom, W8JI's main concern with the K2AV was the unbalanced nature of
the feedpoint, due to the short
electrical length of the FCP counterpoise system.  His
observation was that lengthening the counterpoise to
make it resonant would reduce feedpoint voltages.
I think his points were that he felt the FCP was not
a magic bullet, but he never said the system did not
work.

All I know is that my soil is extremely poor. My K9AY
loop array would NOT show any directivity until I added
four ground radials with additional ground rods at the
ends!  Thus, I would wonder how many on ground
radials would be needed to equal the performance of
my FCP?  Second point, any radials would require
placing the vertical radiator in the middle of an area
with large oak and hickory trees, increasing losses.

Everyone's ground conductivity is different.  I would
think it would be difficult to equate the performance
of a minimal radial field based on individual observations.

K2AV's consistent contest scores certainly offer some
validity to the effectiveness of his system.

Re: Topband: Lack of NA Activity on CW

2019-04-23 Thread Peter Sundberg

Let's ponder:

FT8 - everyone is on ONE center frequency 
(passband) and their computer is transmitting 
every 15 seconds for hours on end, regardless if 
they are in contact with another computer or not
FT8 - all the computers that are "hearing" other 
computers are making use of the built in 50 Hz filter in FT8

FT8 - computers "heard" are lined up and presented nicely sorted on the screeen
FT8 - some computers that are not fully copied 
are still presented as "heard" by use of the "a priori" functionality

FT8 - listening in by ear on 1840 it sure sounds like high activity

CW - people call CQ on an unspecified frequency, sometimes with long interrupts
CW - listeners can't easily surf the band and dig 
in the noise in 50 Hz bandwidth
CW - without knowledge of who is where we need 
good signals to attract our attention and so we can start focusing
CW - summer conditions vary, but one thing is for 
sure, the noise is certainly higher and many have 
taken their microscopes (receiving antennas) down for the season
CW - many of us also have to live with a less 
effective TX antenna during the summer as we have 
to roll in our extensive radial field
CW - the KST chat list a lot of interesting and 
capable stations but most of them don't transmit every 15 seconds

CW - not all who are active announce themselves on KST


Bottom line:

CW - it sure would be easier for us to only 
monitor a specific world wide calling frequency, but this is not realistic
CW - we have to accept that it is more difficult 
to do manual CW than single channel FT8 for reasons described above

CW - if we transmit more we will be heard :-)
CW - we are not lazy operators, we still love CW 
and continue to make noise whenever we can, despite the problems listed above

CW - we take on a challenge, we don't give up
CW- we look at the surrounding actors in a 
realistic way and realize what they are doing, 
duly noting that our table has better food
CW - we fully admire our colleagues in the 
southern hemisphere for being there all the time 
during our prime season up north!


CW is King!

I get that many stations only use FT8 these days (out of laziness?) . . .

But there are plenty of Top Band DXers (like me) who would never ever use
FT8 . . . but many of these people hardly ever come on the band !

It takes a pretty big setup to have a decent 160m DX station . . . what's
the point in having invested all that time and money if the only time you
ever come on the band is to work some DX-pedition?!

Personally, what gives me a buzz is working ANY station on 160m more than a
couple of thousand miles away. (it's the only band where that's actually an
achievement).

I don't care how many times I've worked that station before . . . and I also
don't waste hours trying to get through a pile-up to work a DX-pedition
station, as I'm really not bothered (I've usually already worked the island
they're on anyway)

It's becoming a self-fulfilling prophesy . . . If nobody makes the effort to
come on the band on CW, there will be nobody on the band !!

My K2AV counterpoise is 12 feet off ground, which leaves me with a vertical
run of about 45 feet for the vertical portion of the inverted L.  I've
noticed that the walnut tree I am using for a support has branches that go
up another 25 feet or so... albeit there is a bit more sway in strong winds
the sway is mostly side to side, and pulling on the horizontal run.  I also
have a spring tensioning system in place.  I am considering shooting a
second support line to a higher branch in the tree in an attempt to reach
65 of vertical run for the inverted L.  My question is how much would this
gain for DX contacts?

improvement. The loops really started to work when I added a cheap CATV
ground rod at the end of each radial where the loop outer tie down pegs are

I would think adding radials would lower the Radiation resistance.  Also,
the SWR curve should narrow as ground losses are reduced;  since the effect
of ground loss resistance swamping the results lessens.

At some point I suggest, as others, that you get on for the contest and see
what you can do.  If you can run a bit of power, it will help.  Receiving
is indeed the tough nut to crack on 160 Meters.

Elevated radials may be worth a shot. I think Mike uses two with good

Re: Topband: elevated radial

2019-01-16 Thread Peter Bertini
Hello

You want the elevated radials as high as possible.  3 meters is probably as
low as you would want.  5 meters would probably be optimum.

To be effective, the radials would need to be resonant, and you would need
at least two, preferably four.  The current on each radial should be equal.

Any vegetation under the radials may have some effect. Hopefully the corn
is down and harvested before the 160 meter DX season starts.

As was suggested, the K2AV folded counterpoise, when installed as Guy
suggests, is a good compromise that has enabled many hams to get on 160
Meters when they are in locations that are not radial friendly

If you are interested in experimenting, you could try a K2AV folded
counterpoise under that inverted L.  If installed as recommended, it will
provide a decent counterpoise system.  One advantage to the FCP is that it
is possible to also end fed the system, should that be a requirement.

I was using an inverted L against a tower with random grounding--antenna R
was up in the 80 ohm range.   Over the K2AV, and away from the tower the
antenna R dropped to 26 ohms.  It works good enough for now. I have very
poor ground conductivity, and running a large radial field would be hard
over rocky sandy soil.  I also fed the L over the FCP for  80 meters, an L
Network is switched in to match the antenna, and the FCP counterpoise  is
changed over to 80 meters using surplus Russian vacuum relays.

Those SWR readings seem to indicate a very large bandwidth, to the extent
it might suggest that your ground resistance losses are swamping the

These are spec'ed from 2 GHz down to 2 MHz and if you shop around you can
find them for a lot less than a new CATV splitter.  The satellite stuff has
to work since it costs them bucks for service calls.

One other advantage is that one port has DC pass through, if you need it.

A drain resistor would be advisable if there is no DC return path to

earth it can develop wind or snow induced static voltage buildup, which can
lead to discharges that will cause noise in the receiver. Static voltages

Re: Topband: K9AY loop -- adding additional radials?

2018-11-15 Thread Peter Bertini
Gary. if you are still reading this thread. I have a very early K9AY loop
and mast kit.  I believe my relay box was the second version where you went
from DC/AC control to a three wire DC relay voltage system. The antenna
mast kit used galvanized timber spikes, if that helps date the system.

Was there a modification that showed how to separate the antenna ground
return from the coax feedline? I could never find an exact schematic for
the boxes.

 I did use a FT-240-43 toroid at the FP, but I think I need another core
since it filled up fast when winding the control and coax cable. It seems
to be working well, but if there is a way to make it work better I will do
so next summer when I make the installation more permanent.

Re: Topband: K9AY loop -- adding additional radials?

2018-11-14 Thread Peter Bertini
Adding  four  cheap 3/8" 4-ft  TV ground rods--one  at each of  the ends of
each of the 21 foot radials-- did the trick.  The lone ground rod at the
hub was not enough.  Now have good deep nulls in all 4 quadrants.. Adding
four more radials didn't seem to improve things as much as the first set of
radials and the additional ground rods.  Now a happy camper!!

Topband: K9AY loop -- adding additional radials?

2018-11-13 Thread Peter Bertini
Hello to the group.  I installed a K9AY system last week and added four 21
foot radials on ground radials with a ground rod at the center.  The
antenna didn't seem to have much directivity, so today I added another four
4-ft inexpensive TV type ground rods at the ends of each of the radials.
We've had some heavy rain, but tonight I am noticing excellent nulls on
European stations when changing directions.  The antenna is located in a
wooded area, and I had assumed the ground was fairly conductive, but
apparently not... would adding another set of four radials in between the
existing four improve the system?  I am not sure how much the change
relates to the heavy rains or adding the grounds.

Re: Topband: Which compromise receiving antenna

2018-11-07 Thread Peter

Hi

Here at PI4CC we are busy with building a 9 circle array.
And our motto is DIY so we have create a PCB for the RX preamp around 
the AD8055 ala the YCCC


Some details are at https://www.pi4cc.nl/tech-info/rx-array/
The page will be update later since it is an on-going project

Op 7-11-2018 om 2:40 schreef John Kaufmann:

I designed the YCCC preamp so I can answer the question about the AD8055 op
amp.

As used in the YCCC preamp, the linearity is actually very good.  We use a
YCCC receiving array at KC1XX in a multi-operator, multi-transmitter
environment with 20 foot receive verticals.  That's a pretty severe RFI
environment.  When listening on the array on either 160m or 80m, there is
absolutely zero interference or other noticeable degradations from
out-of-band transmitters.  When listening with an in-band transmitter, there
is a lot of noise near the transmitter frequency, but most of it is phase
noise from the transmitter itself.

If you want more technical detail, here are some of the considerations
behind the choice of the AD8055.  First of all, the YCCC preamp is a kit.
Based on that consideration, I ruled out surface mount op amps that
inexperienced kit builders might not be comfortable with.  In truth there
are some truly outstanding surface mount parts with much better performance.
The AD8055 comes in a standard 8-pin DIP package that's easier to work with
and it was the best 8-pin DIP part I could find.  It is intended
specifically for use in RF systems.

Second, the preamps must exhibit very accurate gain and phase matching to be
used in a multi-element active array.  The YCCC preamp meets this
requirement because it operates with unity voltage gain in a negative
feedback configuration that virtually guarantees extremely accurate gain
setting.   There is no trim adjustment needed at all for gain.  I have done
VNA measurements on many of these preamps built by different people and
every single one of them, when assembled correctly, exhibits a gain accuracy
of +/-0.1 dB gain and better than one degree of phase matching accuracy
across 160 and 80.  The large amount of negative feedback used at unity gain
also contributes directly to low distortion.

I don't have test equipment to perform accurate distortion measurements.
However, the AD8055 datasheet does have data on second and third order
harmonic distortion figures that look very good at 1.8 through 4 MHz.  In
fact these distortion levels are similar to what you might see in a high
quality stereo audio amplifier.

Having said all that, prospective system builders should be aware that DX
Engineering has just discontinued sales of the YCCC preamps as the entire
inventory of these kits has been sold out.  Once their inventory of phase
combiner and direction switch kits is sold out, those will also be
discontinued.  YCCC, as a club, has no intention of selling kits.

I am puzzled by the choice of the AD8055 for the amplifier.
It seems to be unprepared for strong BCB signals.  Has
anyone successfully used this near a BCB station?  I am
6 miles from a 50 kW station.  It seems to me there are
much better amplifiers available.  Or why not a FET follower?

Hello Gang


I am truly saddened to have to pass along the contents of an email I just 
received from Carl Leahy who was one of Jack Leahy,  VE1ZZ's sons.


It is short and sweet - but I will add some personal comments after sharing his 
note to me.

Jeff, our family wanted you to know that dad passed away last evening. If you 
could let the people in the ham world know we would really appreciate it. It 
was a very big part of his life . He had just been talking about you and the 
book you gave him a few years ago..


Carl Leahy
Signing off for VE1ZZ 




++


A few comments from my memory now follow - as best I recall them:


VE1ZZ was not only a personal friend to many of us - he was probably one of the 
finest Topband Dx'ers ever to have lived.  He goes back to not long after W1BB 
came back on the band at the end of WW!! - and was one of the strongest signals 
I have ever witnessed on Topband.  His signal was almost LEGENDARY all over the 
world.  EU stations used to say  - "He is almost as loud when he calls in Asian 
pileups as the EU callers are over here"...and that says it all!


Jack Leahy was personally responsible for my migrating to VY2ZM and was here at 
my home twice - once is 2002 and once in 2012.  I last visited him and Opal 
(his XYL) in August of 2014 with Mike OE6MBG who wanted to meet Jack and see 
his QTH .


When I finally had the time after building my house here on PEI  to visit Jack 
which was probably in July of 2003 or 2004, at first blush his place did not 
make a huge impression on me because it had only a short triangular portion of 
land at the road in the Head of Jeddore NE of Halifax - and the land rose 
rapidly behind his home.  One initially wondered "How does he get out so well 
from here down at the road?"


The answer came shortly thereafter - Jack took me out behind the house - and we 
climbed that hill - up and up and up for something like a MILE - it was a pizza 
slice in shape and very wide at the top of the hill in the woods - with only 
about 100 feet (if that) at the road front side of the parcel.


Some distance up the hill was Jack's 160m 4sq array - which was made of ROHN 6 
tower - that was sitting on 18 wheeler truck tires as base insulators.  The 
towers were not tall - perhaps 55 feet or so and the rest of each radiator was 
wire - so it was really a WIRE inverted L 4sq.  Jack was the "ultimate 
scavenger" and his radials were all 1-2" diameter pieces of HARDLINE!!!  
Hundreds of them all over the hillside  I think he had a friend in CATV or at 
his local dump - but he got most of it for next to nothing he said.


From that point of his land, he could reach around the HILLTOP on 160m to 
acquire  a clear shot to EU and the South was wide open and to the SW was also 
clear looking over the water.  Looking straight up the hill was probably 
blocked to some degree - but often this does not matter all that much on 
Topband.


The day I was there was shortly after Jack had managed to communicate across 
the pond on what I think was 600m - I may be wrong about the frequency - but 
the antenna he used to make the SLOW SLOW SPEED CW contact was something out of 
this world!


It started about 1/3 of the way up the hill - and ran all the way to the rear 
of the property to near the furthest reaches of his land - and this was a LONG 
LONG LONG walk to get there - through some land that I recall was swampy.  It 
had to have been at least 3000 feet long.


Part way up the hill, Jack had built a small shelter in which he placed the 
BIGGEST homebrew loading coil I have ever seen. It was about 4 feet tall and 
about 8 feet in diameter and wrapped around some kind of coil form he had 
created.


Jack explained that it took him awhile to resonate the system to his desired 
operating QRG - and this was done by taking a pair of alligator clips and 
through trial and error he tapped the coil he made - trying to use a DC ammeter 
to find the point of peak current into the system - which he explained seemed 
to indicate the system was reasonably matched.


His was among the first to work across the pond with that antenna - just one of 
his many achievements.

Re: Topband: Use shunt fed tower

2018-09-16 Thread Peter Voelpel
It can work and it does.

I used a shunt fed tower without radials for a couple of years on the former
qth just with the tower grounding.
Now I feed the tower directly and against a single sloping radial, it works
great and is also a better receiving antenna then my relatively short
beverages.

Topband: RX cirrcle array

2018-07-12 Thread Peter

Hi

I like to build a 9 RX-circle for 160M @PI4CC.
We don't have the space for Berverages so this maybe a good way to get 
better RX on 160M


My question is, how do does pre-amps used in the YCCC kit sold by 
DX-engineering hold up, if you use it in a M/M setup where the antennas 
are close spaced?
Close space means all TX antennes are in a 40 by 60 meter lot and the 
RX-circle will by say 50 meter away from  the nearest TX antenna (the 
center vertical RX arry)
Is there any intemodulation of unwanted mixing in the pre-amp if the 5 
othe rbands are trasmitting?


A picture from above and all those antennes in this lot at 
https://www.pi4cc.nl/tour/outdoor/


The pre-amp in the YCCC uses a AD8055

SWR is irrelevant with a beverage, everything below 3 will be OK and it does

Topband: Question for the K2AV FCP users...

2018-05-15 Thread Peter Bertini
Has anyone with poor soil considered or tried adding a few
hundred square feet of  cheap galvanized wire mesh on  the ground beneath
the FCP to reduce ground losses?  I suspect
improving the near field ground losses would help slightly,
but was curious if anyone actually tried it?

Re: Topband: Straws in the Wind ....A 160m Dx'ing Sea Change is Upon us!

2018-04-01 Thread Peter Sundberg
For those who have not yet seen how the future of 160m band 
harvesting - not DX'ing -  will be done, check this video out


<http://ae5x.blogspot.se/2018/01/video-fully-automated-ft8-qsos.html>http://ae5x.blogspot.se/2018/01/video-fully-automated-ft8-qsos.html 



Apparently SV5DKL made 13.000 QSO's on the bands in a few months, 
totally without operator intervention. I bet many hams were happy to 
put SV5 as a new DXCC in their log, Isn't it wonderful that his 
computer was so helpful with that while the operator was busy with 
other things.


As for the legal aspects of unattended operation of a ham radio 
station - who will be able to tell if the operator is there or not as 
it is fully automatic anyway..


In the near future - if we embrace this way of operating -   for 
Wednesday activity nights on 160m we just let our computer do the 
work and check in the morning how many contacts that were made and 
how many that are already credited via LotW. Simple as that.


In contrast to this digital automation it was very interesting to 
read Jeff K1ZM's report from the Spratly expedition on how the 
experienced and highly skilled crew put in a BIG effort to make real 
radio contacts. Way to go!  And I am glad that they did not leave an 
FT8 robot station behind, neatly tucked away in a corner of the 
conference room.. :-)


I do not want to take part in this modern Internet driven computer 
game. If people would disconnect their FT8 computers from the report 
services on the net there would be a lot less amazing contacts in the 
noise as the "a priori" advantage is lost. Then it would be more 
apparent what the radio channel is actually providing for them.


I think that the statement from Ken K4ZW in his recent posting is 
very appropriate:


"For those who think guys like me are dinosaurs, I would kindly 
suggest you don't understand what motives us. 73 Ken K4ZW"


We can't change/stop this new lazy way of automatic band harvesting. 
Many will even make huge amounts of money on the new way of operating.


But we can still do it the old fashion way, as it pleases us to make 
radio contacts. Therefore I will continue to populate the 160m band 
with my CW signal until there are no more stations to work.

Re: Topband: 160M Balun

2018-03-30 Thread Peter Voelpel
Hi Frank,

I just don´t see a reason to make chokes self resonant.
If one really needs that a parallel resonant LC circuit can be formed with a
normal choke and a capacitor.
On my 160m dipole the choke at the feed point is wound with RG 141 on a
stack of two large ferrite toroids which gives me a Z of about 10k.
In addition the outer conductor is connected to the tower after a quarter
wave length and the coax run inside the tower and grounded to one leg.
The same tower is direct fed as an elevated GP at the 25m level against two
sloping radials with the outer connector bonded to the tower.
I never saw any common mode current when the common mode chokes XL was at
least 100 times the coax Z.

Hi Peter,

What you need in a common mode choke is adequate resistive
component to absorb common mode signals as heat.  The choke
doesn't need to be at resonance to achieve adequate choking
resistance, but it doesn't hurt either.   It takes some thought
and technical understanding to determine how much common
suppression is enough.   And common mode chokes aren't the
only way to adequately suppress common mode signals.  


A low impedance radial system provides good common mode
suppression.  Grounding the coax feed line to a center-fed dipole
1/4 wavelength or 3/4 wavelengths from the dipole feed point also
provides good common mode suppression, certainly more than
you ever need for a dipole. This assumes that the feed line runs
at approximately 90 degrees from the dipole.   Pulling the feed line
significantly away from 90 degrees significantly increases common
mode.  An  off-center-fed dipole is much worse because its very
difficult to build a choke with adequate power handling capability
and good choking performance.

You can't understand your needed common mode signal suppression
without understanding your signal environment and the directive
performance you want to achieve from your antenna.  


For example:


A multi-transmitter or SO2R station needs much more attention to
common mode suppression than a single operator low power station


A highly directive multi-element Yagi needs much more common
mode suppression than a dipole or a vertical.


Coax feed lines properly installed and bonded to a tower has less
common mode signals than a coax feed line suspended well above
the ground. 


Perhaps the worst case need for common mode suppression is
directive receiving antennas with very low signal levels such a small
terminated loop (K9AY, Flag, etc) or a small "magnetic" loop. Both
require extreme attention to common mode signal suppression,
including a strong preference for buried feed lines, control lines
and power cables.

Re: Topband: low inv-vee

2018-03-29 Thread Peter Voelpel
I never heard a dx station stronger or better on my 30m high dipole then on
the vertical, even not broadside to the dipole.
For that reason I don´t believe that dx signals on 160m are coming in at
high angles in opposite to all other bands, except perhaps sometimes during
grey line, then both antennas are equally good at medium distances.
And an inverted vee has no advantage against a dipole, just less gain.

I seem to recall reading that the "ideal" angle between the legs was 110 
degrees. How that was derived or even if it is true I do not know.

I had a half sloper and converted to an inverted vee. I had done fairly 
well with the half sloper and not too bad with the inverted vee but with 
the inverted vee I would occasionally see cluster comments that I was 
deaf from EU. Nothing scientific here. Plotting QSOs between the two 
showed that the more distant QSOs were on the half sloper but that could 
be propagation or other factors not specifically because of the antenna. 
The half sloper was attached to a 100 foot  45G at about 66 feet and the 
inverted vee apex was at 95 feet suspended out from the 45G. At the top 
of the 45G was a KT36XA, 80M rotatable dipole, and a 2 el 40M yagi. The 
two were not up at the same time so there is no true A/B comparison and 
RBN wasn't around yet.

Station B in Europe via a webSDR located 50 km away from Station A in 
North America.


- Station B in Europe is calling Station A - who is listening via a

- Both stations exchange 599+ reports and greetings for a fine QSO.

Wow, their signal made it 50 km via the airwaves at both ends and was

Re: Topband: FT8 qrm

2017-11-29 Thread Peter Sundberg
This is Joe Taylor K1JTs description of how WSJT-X default 
frequencies (windows) are established:


"The authors of WSJT, MAP65, WSPR, and WSJT-X have never attempted to 
impose standards for operating frequencies of our various modes. 
Sometimes we have made initial suggestions, usually with IARU Region 
2 in mind.  But the frequencies in use today are effectively 
established by users, not by us.  When conventional usage seems well 
enough established by the community, we have added mode-specific 
default frequencies to a list in WSJT-X "


To me it seems pretty clear that if the software is pre-programmed 
with a set of default frequencies for different bands, the users are 
NOT spinning the VFO to find a clear space. Last summer this concept 
created quite a bit of commotion in Region 1 among users of a higher 
band as the WSJT-X default frequency was not in correspondence with 
the R1 bandplan.


So, to answer your question Mark - Mr Taylor and his colleague 
authors of a software bundle.

A few friends have asked about VE1ZZ since he has not been on Topband much
lately.


I gave him a call yesterday on the phone and he said he is nearing his 82nd
birthday but has been slowed down by age and other things.


He said he has COPD and cannot get around very well these days - antenna
work in his woods is no longer possible.


His main AMP is down as is a backup amp and he hopes to get on a little now
and then if he can fix one or both.


Hi great wife - OPAL - fell down the cellar stairs not long ago and is
slowly recovering at home after a long hospital stay.


I was saddened to hear these things but expected something was amiss over
there.






Jack has long been the BEACON here in Canada on the lowbands and his absence
has been missed.  He lives about 120 miles to the SE of me here in CANADA.


He was largely responsible for my emigrating to Canada in 2000 and creating
VY2ZM here on Prince Edward Island.  Jack once told me "Jeff, Cape Cod is a
pretty good location. but IT IS NOT AS GOOD AS HERE!!  You should come
up here and see for yourself." ..And boy was he ever right!


BTW - I noted Opal his wife.

We ALL might wish for a wife like Opal.


When I first met her in 2002, we talked about HAM RADIO and Dx'ing and about
how much Jack has been a fixture on the lowbands since the mid 1950's.

What she said I will never forget - as it was memorable:


She said:


"JEFF - WHEN I MARRIED JACK, I KNEW HOW MUCH HE LOVED DX'ING AND HAM RADIO
AND I REALIZED THAT THE ***BIGGEST*** MISTAKE I COULD EVER MAKE WOULD BE TO
HAVE TRIED TO GET BETWEEN HIM AND HIS LOVE FOR RADIO!!
  IT IS A BIG PART OF OUR LIVES!!!"



Anyway, I thought I might pass on what I knew - sure hope to hear Jack on
now and then again soon.

With some of the new popular digi protocols most

As a well known 6m op said after summing up his

2017-09-12 Thread Peter Sundberg

Congrats Gary for scoring by using FT8.

This new protocol will be a blessing to all who want to make DXCC 
without effort - you just put it into "Gardening mode".


This is what a G-station told us on another reflector recently about FT8:

"But it is possible to create your own "QSO machine" which doesn't 
need any human intervention. See my email of 26th August at 2047 GMT 
("Fully Automated QSOs").
My version works with WSJT-X RC2 and either Windows 7 or XP (but 
unfortunately not Windows 10). I just put it together as an 
experiment, so I don't want it to be widely distributed, and I can't 
spend time supporting or developing it. But it works, and it's 
fascinating to watch it making QSOs on its own."


So, the fascination of working new countries by taking part yourself 
is soon to be replaced by the fascination of your computer making 
these QSOs on its own, adding them to your DXCC total. While you are 
off doing other important things.


As for me - on any band - CW is King.

Please check the pattern on 60 and 40m where the 37m high vertical is going

You certainly will see the high angle lobes.

The free-space pattern of current in a vertical (and also  horizontal)
antenna is crescent shaped with its maximum at the midpoint, and a minimum
at each end.  It shows nothing that could be termed an extraneous lobe.  Any
such lobes would seem to be the result of improper matching, or more likely,
the fact that in the real world such an antenna is in an environment that is
certainly not free space.

Re: Topband: Top Band and JT65

2017-05-22 Thread Peter Sundberg

Mark,

What you are saying is, that by using the K1JT shorthand messages, i 
e single carriers representing a report, confirmation "RRR" and "73" 
we are seeing a wonderful advancement in communication technology. JT 
shorthand messages are nothing but a carrier at a certain frequency 
offset. They are used all the time to make these wonderful QSO's, 
taking people up the DXCC ladder at higher speed than ever before.


If only detecting a carrier would have provided me with confirmation 
of a QSO on Top Band I would certainly have more countries in my log 
than I do now..


There is nothing wonderful about lowering the amount of data 
transferred via the airwaves to virtually nothing to complete a QSO, 
it is going backwards rather than forward in advancement in my view.

Hi Bob, 

 

Welcome to 160m !

 

Milt Jensen N5IA (sk) used his huge array in the 160m contests to work
thousands of miles east and west while he was in full sunlight. (In fact I
believe he was the one who sponsored a plaque for daylight operation only in
the Stew Perry Contests)

For some of these exciting reports (too lengthy to reproduce here) go to
3830scores.com and type in N5IA.

Look for the Stew Perry Contests (SPTDC) and his call N5IA(N7GP) then read
his DAYLIGHT reports.

 

Incidentally the first real exposure to daylight DX I personally experienced
was from CY9AA in 1997 when myself, Doug, VE1PZ and Dennis, K7BV setup on
that tiny rock in the Gulf of St. Lawrence (N. Atlantic area).  We had a
wonderful balloon supported 1/4wl wire vertical tied into a massive copper
groundscreen (leftover from a VLF beacon) and a salt water Fresnel zone.
With that setup and legal limit we were able to work EU a cpl hours before
sunset on that desolate rock.  An unforgettable experience.

 

Big stations like VY2ZM, VE1ZZ, etc. do the same all the time.

 

It still is exciting !

 

>From my home with a small-moderate sized 'array' of 2-inverted L's phased I
can SOMETIMES work EU just a little before sunset (pre-grayline) here and
have worked out as far as KH6/VK/ZL to a little after sunset here(post
grayline).  Hardly full sun, but it does show what can be done when you
think it not possible.

 

Have fun !

My elevated radials are now 24m up but sloping.
Big difference to before where I tried 4m high radials.
I went from a T-vertical to a driven tower with top load as an elevated
groundplane some years ago and that is the best transmit antenna I ever
used.
It is also outstanding on receive. I can hear weak stations with it which
are inaudible on my relatively short 160m long beverage.

Hopefully this will increase some of the efficiency lost from the low

Re: Topband: Battle Creek Special - 160 Resonance

2016-10-29 Thread Peter

Hi

I have note from George and its on our webpage
https://www.pi4cc.nl/link/extra.php

Peter
PC2A

Dear OM Peter:

Something you need to know about your website:

The Battle Creek Special is designed for use from 7.0 to 7.3 MHz and the
trap should be resonated close to 7.0, not 7.1 MHz.

On 80 meters the design frequency is 3525 KHz, and the bandwidth is 3500
to 3570 KHz. The trap needs to resonate at or below 3525. The trap
data you give will resonate at 3750 KHZ which will reduce the
performance on 80 CW and may give other problems. The capacitance to
resonante 9 uHy at 3.5 MHz is about 225 pfd.
The Battle Creek Special uses two pieces of RG-213 about 4 feet long, in
parallel, to get this capacity and they hang below the trap inside the
top section.
Please correct your diagrams to reflect this.

Also do not forget the 2:1 UnUn (9:4 UnUn also works) to bring the
impedance on 160 up to about 50 ohms.

With L=9 uHy, C is best at 229 or 230 pfd for resonance nearest 3500 KHz

With C = 200 pfd, L is best at 10.33 uHy for resonance at 3500 KHz

I built this antenna several years ago. I never really had a good resonance
on 160 though. Best I could do was 3.5:1 or so. I used the xcvr ant tuner to
match it without issue.
  
Since it had been up for many years I brought it down a couple weeks back

for maintenance. I reworked the traps and adjusted the length of the first
section to give me a better match in the CW portion of 40m.
  
The reworked traps dip at approx 7.12mhz for the 40m trap and 3.5mhz for the

80m trap.
  
Put the antenna back up today and have a nice match in the CW portion of 40,

but the 80m resonance has shifted down to around 3.3mhz and I see no
resonance on 160m.
  
Some numbers from the MFJ analyzer:
  
40m 7.05mhz 44, 10 and 1.2 VSWR
  
80m 3.51mhz 91, 136 and 5.8 VSWR
  
160m 1.81mhz 18, 37 and 4.1 VSWR
  
I have about 40 radials varying in length from 50 to 60 feet depending on

the yard.
  
The 80m loading wire is approx 15' long
  
The 160m "L" is approx 72 feet long
  
The overall height of the antenna is 50ft.
  
Any suggestions for how to obtain a better resonance on 160?

Any suggestions as to who is active from MS on 160m with a good

Topband: Tee Antenna dimensioning

2015-10-18 Thread Peter Bacon
Advise please on the formula to calculate the lengths of the horizontal
elements for a 160m Tee antenna.  Currently I have a 60 foot vertical wire
suspended between the trees, with a long horizontal section making an
inverted L, but want to change it to a Tee.  I am looking to resonate the
antenna around 1.9 MHz and then bring it down with a hairpin match.
Thanks Peter G3ZSS

Re: Topband: Which is best for copying the weakest DX - DSP or theear-brain combo?

2015-08-07 Thread Peter Sundberg
It is interesting to note that Tom and others share exactly the same
experience as I have. There is a certain 'flavour' to DSP audio that is not
making it easier to copy weak signals in the noise. I find that using an
(old) analog system actually makes it much easier to copy signals hidden
deep down in the noise.  

I have long experience from listening to extremely weak signals in the
noise (CW EME on VHF/UHF and some while Topband DX'ing) and I am still
waiting for a DSP radio that outperforms my old analog radios and my
homebrew LM13600 audiofilter. The filter was published in QST in October
1983.  

For EME, my TS2000X with it's filter combinations is just not as
comfortable to listen to as the old FT736R and my vintage LM13600
audiofilter. I plain words, I copy much better on the old system. And DSP
in the low end Yaesu radios (FT817/897) is not performing anywhere near the
old analog systems. The same goes for the SDR's that I use. 

Granted, tuning in a very weak steady carrier in a narrow DSP filter (a few
tenths of Hz wide) can give you the impression that DSP is magic stuff. But
as soon as the carrier is chopped up into CW there is a 'mushiness to the
DSP processed white noise that affects copyability. For me, this can often
be verified when doing an A/B check on a very weak beacon that sends a long
carrier between it's CW ID's.

In my view, even static crashes when listening to weak signals on Topband
are easier to deal with when using analog filters.

But the whole audio chain is important. The choice of headphones is
certainly a key to success when it comes to copying weak CW in the noise.
Each one of course has his/her own preference when choosing headphones. My
best ever are a pair of very old Radio Shack Nova 10. They are badly
beaten and patched up with tape and glue, but I still use them every day
and they are the best headphones for copying weak CW that I've ever tried.
And beleive me, I have tried many headphones.

Some good tests for copying weak signals in the noise can be found at
http://sm2cew.com/wavefiles.html 

There might be one or two broken links on that page after a transfer to a
new server but try the plaintext59_17.wav it is a real challenge. There is
a genuine 59 character CW message in the noise and it is possible to copy
and decode it 100% by ear when using a good filter. Good luck!

 contesters) beat state-of-the art digital signal processing when it comes
 to copying the very weakest of signals buried in the noise?

Excluding time-synchronized signal processing methods, I've never found any 
DSP system do better or do more than an analog system in signal 
readabilitly.

They are really just different methods of doing the same thing analog 
systems can do.

I actually find DSP detector systems inhibit my ability to hear or copy 
noise floor signals in rough noise. I'm not sure why that is, but it is more 
difficult for me to piece together a signal that is in the noise when it has 
been detected in a DSP system.

I normally set my K3's so DSP filtering is wider than the analog filter at 
filter switch in, so I can change the DSP bandwidth from wider than any 
analog filter down to the DSP being narrower, but I still think analog 
detection is much better for signals below the level of rough noise.

radialfield is out of 100+radials between 5 and 20m long..
think about 3 options

1 ?? keep it as it is

2 ?? make it shorter arround 22m and set 2 10m long wires ore??? ? ? ?? ???
??? ? maybe? 15 m? 45 degrees down as top load

3?? take? the 2 upper sections of the titanex away and fix a 8m? 
? ?? spiderbeam pole inside? so i will get a total high of 32m

ore maybe a shorted delta loop matched with a coil in resonance?

Re: Topband: Use of Remote Receivers During 160 Meter Contests

2015-03-15 Thread Peter Voelpel
CQ is quit clear in the description of a contest location:

The area in which all the transmitters, receivers and antennas are located.
All transmitters and receivers must be within a single 500-meter diameter
circle. Antennas must be physically connected by RF transmission lines to
the transmitters and receivers.

Anyway, I hear EA3JE almost daily on 80m receiving US stations via websdr in
the states and using big power to get over the pond. He doesn´t even bother
that his vox is acting on the audio from the remote receiver, so doing it
quasi full duplex.

Is that to become the future of low band contesting?

on 160. (And who knows how many of them are in quiet locations?)

When I say terrible, I mean small magnetic loops, very short whips, low

Re: Topband: Modeling the proverbial vertical on a beach

For Skimmer comparisons signals have to be on the air at the same time and
the transmitting stations not to far apart from each other.
In that case there is no statistical noise.
But I would not expect the here claimed 20db difference.

 Skimmer shows about the same peak levels, but the stations closer or

 K3LR is about as strong into Europe, when I look at skimmer levels, as 
 someone on the coast.

 The exceptions are people right next door to Europe (like VY1).

Tom,

How much skimmer data did you mine before establishing a firm conclusion 
that the advantages of saltwater proximity are exaggerated?

Myself, I think of how well AA7JV and HA7RY have done at various 
locations using antennas that were very close to or in some cases 
literally in the saltwater. The consistency of their topband signals 
compared to Dxpeditions who were confined to inland locations seems to 
point to a big advantage. I'll admit, however, that this hypotheses 
comes about from anecdotal observations filtered through a mental lens 
that is biased towards believing saltwater is a huge advantage.

I think using skimmer is an excellent approach to this question provided 
of course that you have mined enough data to filter out the statistical 
noise.
