Topband: ZLs

2024-01-30 Thread Mark
Just a few observations from ZL...

Firstly there are very few ZLs on topband in any form.  In terms of CW ops
you could probably count them on one hand.  In 160m contests if there is
more than 1 or 2 on then that is a lot and you shouldn't be surprised if
there isn't any - which is normally the case in the big multi band
contests.

Also the timing of this "contest" (thanks to the scoring system it's really
more of an activity weekend in this neck of the woods) doesn't do us any
favours down here or in the southern hemisphere in general.

As Tree noted, it is the middle of summer here and the QRN can be
diabolical and of course we have a lot less hours of darkness.

With darkness such a big factor and the fact it is called a "world wide"
contest, I am surprised this contest isn't run around the equinoxes to
level the playing field, not to mention evening out the effect of QRN.

It is probably also worth noting that the second night is Sunday night here
so anyone working in the morning is not likely to be up late.

Topband: 160 meter report

2024-01-06 Thread Mark Lunday
Heard but could not get through to OK1CF @ 0010 UTC.  Long QSB from 559 down to 
the noise level.

Worked OH0Z at 0005 UTC.

Checked back in at 0430 UTC and signals were barely audible amid QSB.

Topband: Wednesday activity report

2023-11-01 Thread Mark Lunday
OK1CF/Karel heard about 0040 UTC calling CQ, very deep QSB going from Q5 copy 
down to nothing and back again.  K4TL worked him from Florida but I was not 
heard.

I called CQ numerous times but no replies.  Even with 500 watts I was not 
making it onto any of the RBN spotters from EU.

Went up to 80 with 500 watts and was spotted by G4IRN.

This is depressing.  I don't have high hopes for the 160 meter contest in 
December.  What a difference from 2009-2010 when 100 watts easily got me into 
EU and middle east.

Topband: Wednesday night activity report

2023-10-18 Thread Mark Lunday
I decided to start this season off early, with a promise to be more active on 
Wednesdays.  0100 UTC I flipped on the rig.

I was unable to get a spot in EU on reverse beacon network even with the amp 
on.  I listened for my signals on some of the KiwiSDR's and could only hear 
myself on one, just barely.  160 had this pulsing repeat like a CW note, every 
1 kHz on every EU KiwiSDR I listened to.

Went to 80 and tried again.  Still lots of noise.  Finally spotted by G4IRN 
with the amp on.

I know it's early in the season, but I have had many 80 meter transatlantic 
QSO's in past years as early as 1 October.  The CME isn't expected to arrive 
until 1800 UTC on the 19th.

I was disappointed.

Re: Topband: Topband - Stew Perry event just 48 hours away

2022-10-21 Thread Mark Connelly via Topband
There are many more SDRs online than are actually of much use for weak signal 
DXing.
The map at http://rx.linkfanel.net/shows many sites.
What don't usually show are special temporary DXpedition operations.
DXpedition set-ups are typically at low noise coastal or high-altitude sites 
not near urban RF congestion. "Real" antennas, i.e. with decent gain and 
directivity, are typically used. For these reasons the short duration 
DXpedition receivers usually blow the doors off what "permanent" sites offer.
Long-standing, if not permanent, sites along the North Atlantic that I have 
found somewhat useful, such as when I have to disconnect my own stuff during 
lightning storms, include the following:  
Stratford, PEI, Canadahttp://47.54.214.91:8073/
Rockport, ME, USAhttp://rx2.wa2zkd.net:8073/
E. Falmouth, MA, USAhttp://kb1vwc.ddns.net:8073/
Elizabeth City, NC, USAhttp://kiwisdr.ku4by.com:8073/

Bjargtangar, Icelandhttp://tangar.utvarp.com:8073/
Ireland (NW)http://irelandnorthwest.proxy.kiwisdr.com:8073/
=
Antenna on most/all of the above should be considered non-directional, at least 
by what I'm hearing.
There had been useful receivers at Key West, FL and in the Dominican Republic 
but those are no longer active. There was also something on the western shore 
of South Africa - that one also gone.
There's one in Trinidad which should be useful but is deaf / noisy.

have 5  wires whch are two full size 160m wires, two full size 80m wires 
and a 60m wire.   I don't need a tuner on any of these bands.  It needs 
slight tuning on 30m.  I worked Amsterdam Island  on cw with it.

This is what my 120Hz line noise sounded like.  Halfway through the

I don't think this is line noise though. It sounds quite different.

Topband: 160 report

2021-11-25 Thread Mark Lunday
Conditions were pretty good overnight…lot of activity with some QSB on EU 
signals.  I had a late Turkey feast and did not get on the air until 0300 UTC.

I heard G3ROO calling CQ, and then several EU stations calling HP3SS.

I worked G3YRO, but it required my amp and patience from Roger.  Some QSB, but 
we did exchange RST.  Thanks, Roger.  When do you sleep, OM?  

Then worked SM5EDX; John was true 579 but also with QSB.

I called OZ4MM/Stig, but he did not hear me.  Also heard HA8RM/Peter, 
F5IN/Mike, OK1CF/Karel, ON7PQ/Pat, all fairly strong but with significant QSB.

Then worked TF3SG/Gudmi for new one on TB.  QSB took him from 589 down to 339.

Nice to hear so many stations on the air.  I went offline at 0430 UTC.  Looking 
forward to the weekend contest!

Re: Topband: cheap radial wire?

2021-11-11 Thread Mark - N5OT
Something I have not seen mentioned in the large number of posts about 
cheap wire is:


My wife and I go to garage sales and estate sales almost as a hobby.  
Quality time and all that.


I have found that many of these kinds of sales have quantities of wire 
in the garage part of the sale.  "I'm going to check the kitchen, honey, 
you go see if there's anything interesting in the garage."


I have found that in maybe 2 out of 3 of these situations the person 
doing the selling realizes the value of wire these days.


But in the other 1 out of 3, I have found some total steals. Notably I 
picked up 2000 feet of insulated #18 on 4x 500' spools for $5 a spool 
once and 1000 feet of #10 house wire (THHN Stranded) for $15.


Most of the time they don't have thousands of feet of wire laying 
around, but ... sometimes they do.


People get it into their head that it's crap they need to see go away, 
and sometimes they are really happy to get a few bucks for what you 
would pay $50 or $100 for at the wire store.


I also have one of those permanent eBay searches going for spools of #18 
wire.  Most of those sellers know what it's worth, but occasionally they 
don't and for whatever reason it has stayed under the radar.


Truly, I have bought so much wire over the years that recently I 
realized I now had more than I would ever use for the rest of my life, 
so I should stop buying it.  My heirs will sell it off for pennies on 
the dollar I'm sure.  Meanwhile 160 meter verticals are a great antenna.


And so it goes.

The first one worked well until I had a bad wind.

The second one had some kind of corona arc off the top of the wire which 
popped the (relatively expensive) balloon after only a couple minutes of 
testing it out.  Or something.  It popped on a clear calm day but under 
Full Power.


Anyway, that wrecked my day.  I decided it wasn't fun any more and have

I think we wrote it up in the NCJ but don't remember and have slept

Oh sorry, you asked where to get the balloons.  I think I got mine from

Note - Googling reminds me of these facts:

Helium can lift 1 gram per litre.
A balloon 2 feet in diameter will contain 118 litres of helium.
That will lift 118 grams of antenna, = 4.1 ounces.
132 feet of bare #18 solid copper wire weighs 10.4 ounces.

A 2 foot balloon filled with helium will not lift a 160 vertical made of 
#18 wire, not to mention any extra line or insulators, etc.


But a 4 foot balloon will lift a little over 2 pounds.

Now I'm having nightmares again.

Re: Topband: Twin Sloper

2021-07-14 Thread Mark Robinson
I have a modified Alpha Delta sloper..well it started out as an Alpha 
Delta mounted at 70 feet on my 86 foot tower.  I jumpered the loading 
coil and lengthened the 40/160m wire to 130 feet or so.


 I now have 5 sloper wires. Two are for 160, two are for 80m and one is 
for 60m.  I run it without a tuner on 1.8 - 1.92 with an swr of 1:1.8 
over that range.  It covers 3.5 to 3.85 with under 1.8:1.  It will also 
load easily with a tuner on 30m.  No tuner is needed on 60m


It did work on 40m until I added the second 160m wire and then I just 
increased the 40m wire to cover 60m instead.  There is some interaction 
going on which I never really investigated


To get it to work on 160 without a tuner,  I had to add a 140 foot 
counterpoise  wire which is connected to the tower leg at 70 feet where 
the feed coax is attached. This wire then slopes out in the opposite 
direction of the two 160m wires.


This sloper has worked very well for me.  Give it a try.  It worked 
Amsterdam Island on 160

  Rather than to buy one, was thinking of having the same two lengths of wires, 
fed through a remote tuner at the same feed point (top of tower).

The tower is 55' above ground and is grounded via a downlead to a stake.

Will this perform roughly the same as the Alpha Delta?

Guy (K2AV) - I really liked your explanation about the function of a radial

But I've often thought about the other extreme . . . I have a homebrew 2m
Ground Plane on top of my mast . . . just a quarter wave vertical . . . and
3 quarter wave radials sloping down about 45 degrees.

Now if those radials were vertical, it would really be a vertical Dipole . .
. i.e. the radials would be radiating.  Whereas if they were horizontal, I
guess they wouldn't be.

You get my question . . . what really is the difference between the 3
different radial situations?

And here's another question . . . rather than all the issues of radials and
matching, has anyone ever used a Vertical Dipole on 160m ?

Sure, you're not going to have a 260 ft vertical . . . but suppose you had a
100ft support, so that you could have 50 ft vertical legs either side of the
coax feeder, and then just bend the legs at right angles at the top and
bottom to make up the length (linear loading) - maybe running in opposite
directions.

I would have though that would be quite an efficient antenna?  And
presumably (just like any dipole) it would work even better if the ground
underneath it was very poor (in my opinion)

Thanks for the update, Roger. Unfortunately, work is kicking my butt with 12 
hour days and weekends because of Covid. I will be 57 this year, getting too 
old for this stuff.  Not sure how much longer I can work in customer-facing 
roles in Info Technology. Maybe I need to take up a job that doesn’t follow me 
home...union plumbers make great pay and nobody wants to be a plumber or work

Re: Topband: Wednesday CW DX Activity Night

2021-02-17 Thread Mark Connelly via Topband
British medium wave stations may be usable to indicate viable propagation.

Here in Massachusetts, I frequently hear 693, 882, 909, 1053, 1089, and 1215 
kHz.

Absolute Radio on 1215 is probably the most consistent. Rock music format 
stands out. Its position halfway between two US channels (1210, 1220) helps.

Depending on what your local interference is, one of the other channels may be 
better.

Sometimes the aurora impedes northern European reception but the path to Spain 
and North Africa is still good. There are a number of stations from that area 
that can be checked.

This might be useful:
https://www.qsl.net/wa1ion/doc1/audio_2020.htm

Local sunset here and just before dawn on the eastern end of the route tend to 
be slightly better than the middle of the night.

Going the other way, Europeans may want to check for North American MW signals. 
590 and 930 from Newfoundland are best. ME on 1390, MA on 850, and NYC on 1010 
and 1130 are common.

Propagation on those lower frequencies may or may not indicate 160m viability, 
but it can be a useful tool besides more customary things that depend on hams 
being on the air.
Mark Connelly, WA1ION | South Yarmouth, MA, USA | FN41vq

<<
Well activity is when there is Propagation, ie during the darkness hours,
from your Sunset to Sunrise where you want to work.

I personally come on from around midnight our time ( Z), and try and pop
back on a couple of times during the night.  Sunrise here in Britain is
currently around 0700 Z.

Re: Topband: K9AY Loop Question

2021-01-17 Thread Mark - N5OT
Hi Pete, I have a PILE of experience with K9AY loops, but I don't use 
them in the usual "one-support-two-loops-four-directions" 
configuration.  Mine are all individual loops on individual supports 
dedicated into arrays in various directions.


The first thing I would check is to make sure you have continuity 
through the torroid inductors/transformers.  I have had loops work only 
sort-of when it turns out one of the teeny wires opened up. So it ... 
"kind-of" worked.  Like I could hear some signals, but the loop just 
wasn't behaving like it was really supposed to.


Another thing you might check is to see that the termination resistor in 
the box is not somehow broken / open / shorted / something.  The other 
things you describe, shape of the loop, sloping ground, etc, seem to not 
matter in my experience.

How important is the geometry of the loops?  Illustrations I've seen 
seem to imply that the lower legs should slope upward somewhat to the 
corners, but without dimensions other than the total length of the loops.


The ground around the antenna slopes slightly toward one side - should 
I attempt to get the corners in the same plane, or the same distance 
above ground?


The relay box is mounted on the central fiberglass pole is 
approximately 2 feet above ground.  Is this dimension important? The 
relay box is grounded to a ground rod very close by.  Last year I 
experimented with also laying a couple of radials on the ground under 
the loops.  I read that suggested somewhere, but don't know if it's a 
good or bad idea.

Strange as it sounds, (living where I live and all that), sometimes

Re: Topband: I need help proofing an Inverted L model I made please. 40’ x 143’, four 100’ radials, #14 wire.

2020-12-10 Thread Mark - N5OT
Yeah.  I don't claim to be a radial expert but I do claim to have a lot 
of experience working other stations on 160 meters.


My buddy W9RE told me on a DXpedition once that he built a dipole laying 
on the ground and it resonated on 160 when the wires were about 80 feet 
long.


Ray, with respect (N6VR and I go back a LNG way), I think 80 feet is 
the "new quarter wave radial" on 160, and frankly the only thing I 
really think I understand about verticals is, the more wire on the 
ground, the better, but you can get to a point where adding more is not 
worth the effort, YMMV etc.


My story for the week is:  I put up yet another temporary 160 vertical 
for the ARRL 160 last weekend, and only managed 14 radials before it got 
so dark I thought I better be getting on the air.


I worked 970 QSOs that night, including 5 Europeans, and while I was out 
there on Saturday adding more radials, I got a text from K5ZD saying I 
was an alligator, that I was very loud the night before, but couldn't 
hear him calling me for 10 minutes as he needed Oklahoma.


So I stopped adding radials, I was up to 22 radials at 80' long, and 
moved on to listening antennas.


Worked maybe 10 Europeans and counted 10 JAs, so I know my signal was 
getting to those places.


That's really all I know about that.

The vertical is 50 feet tall and has two symmetrical top-load wires that 
bring the resonant frequency to 1.8 MHz.


73 - Mark N5OT

P.S. Got an email from a guy in South Dakota who worked 376 QSOs 
(including 4 other countries) using an inverted L that was 20 feet up 
and the rest horizontal, fed against 20 radials 25' long in his yard.  I 
love stories like that.



On 12/10/2020 9:52 AM, Wes wrote:
IMHO, for that number, on-the-ground radials do not need to be 
anywhere near that long.  Personally, I subscribe to the 
same-length-as-the-vertical guideline.


My inverted-L is 55 feet of vertical tubing plus the horizontal wire.  
My insulated, on the ground radials are 55.5 feet (9 radials out of a 
500 ft roll of wire). By serendipity, measuring one radial against all 
of the rest with a VNWA it is resonant at 1.84 MHz.  To be fair, I 
still have fewer radials than planned (18 vs. 36) in which case, 
shorter is actually better according to Belrose and Severns 
(https://www.antennasbyn6lf.com/files/antenna_ground_system_experiment_4.pdf).

>his well-equipped station in New Hampshire.  It's fascinating!  Rick was 80M 
>DXCC #114; he has been on 80 meters for a long time.

So today I decided to listen in on 3793 kHz about 2310 UTC onwards, which is 
the time of the daily schedule.  I was using a HiZ 4 square receive array and 
an inverted L with 500 watts for transmit.  The rig was an unmodified Icom 
IC-7300.  Soil conditions here aren't that great, and I am 200 miles from the 
coast so I don't get the benefit of saltwater enhancement.  Still, VK6APZ went 
from ESP level at 2310 to 4x4 on peaks (with QSB) by 2330.  Although we did not 
complete the QSO, we came close.  Meanwhile, Rick reported 5x9 copy on Peter, 
strongest signals in months.  

This is quite remarkable, because my path to the Northeast was strongest (just 
like K2RR observed) but I was 600 miles SOUTH from K2RR.  If this was spotlight 
prop, the spotlight was in motion and came down the coast!

While VA2GU and K2RR have proven that QSO's on low bands in daylight are 
possible with EU if the equipment and antennas are of the highest order and 
conditions are just right, this is an entirely different and incredible 
situation.  Long path is unique.  Long path on the low bands is quite 
exceptional (I keep reading your 5th edition book on the subject).  Long path 
with daylight in part of the path on 80 seems almost too good to be true, but I 
heard it myself.

Thanks to Rich/K2RR who let me participate today in the fun, and to 
Peter/VK6APZ for his patience and persistence.

Re: Topband: Some experiments with a short beverage, not succeeding very well

2020-07-04 Thread Mark Lunday
Update - with the issue resolved, the beverage does hear DX on 40 meters, and 
is quieter than the inverted L as expected.  It is able to hear signals to NW 
and SW, which is also expected due to the shorter length.  This is just two 
nights of observations, bu tI will continue to perform additional experiments 
over the summer with lots of static and see how much quieter it can hear 
compared to the inverted L.

250 feet of beverage is certainly usable as a receive antenna.

Thanks again everyone for the help!

Topband: Some experiments with a short beverage, not succeeding very well

2020-06-30 Thread Mark Lunday
"Beverages just want to work" is what I have heard.

Not having much luck with that here.  I suspect operator/installation error.

I did a lot of reading and I must be doing something wrong.



  *   250 feet of insulated wire strung out in 030 degrees direction toward EU, 
pretty straight, varying in height from 4 to 6 feet, running through thick 
brush with no metal objects or artificial elements along the run.
  *   9:1 transformer at feed point with ground rod
  *   300 feet of coax, mix of RG-8, MMR-400 to get to the edge of the woods 
from the house
  *   No terminating resistor

On bands 160-40, the signals are very weak. I am monitoring WSPR, FT8.   I can 
hear signals on 160-40 but they are way down compared to dipoles and inverted L 
on the same bands. Like 20-30 db down. From what I read, I should NOT need an 
HF pre-amplifier, right?

Signals on 30 and 20 seem to be better and I can copy some DX from EU on FT8.

I will try installing a new ground rod, the old one is 10 years old and perhaps 
not making a good ground connection at the feedpoint.   The transformer is 
brand new, so that's not an issue.  The coax has tested out fine.  Soil is 
central North Carolina clay, a bit dry at this time.

I am guessing performance is poor on 160-40 because of the short length and 
that it's bi-directional (no terminating resistor), which I am seeing on 30 
meters. But I did not think it would be THIS bad on 160-40

Re: Topband: Inverted V vs inverted L

2020-04-19 Thread Mark Lunday
>>> The inverted L will out perform and inverted vee, hands down, 90% of the

times) when horizontal polarization can work better   Dave, W0FLS<<<

This conclusion regarding probability is supported through numerous 
observations over the years in various texts and documented in John Delvodere's 
"Low Band DXing" 5th Edition Chapter 14 Section 7.

But each installation is unique.  These are probabilistic forecasts (like the 
weather).

The important thing is to go into the experiment with realistic expectations 
and a priori knowledge of most-likely outcomes.  But by all means, experiment!  
Share your results!  We are all learning new things every day, especially about 
Top Band.

I will share my experience when I phased two dipoles on 80 meters, 20 feet high 
above average soil, as an experiment:  I presumed, based upon standard 
literature I had reviewed up until that point and 45 years of personal 
experience, that the installation would be a "ground warmer."  

Imagine my surprise when I was able to easily hear and work into EU running 
QRP!  I learned a lot from that experiment and VA2GU's assistance (although 
John Delvodere does discuss this type of antenna at the beginning of Chapter 12 
in the 5th Edition).  VA2GU has evaluated phased wires extensively and has 
collected data to confirm his conclusions (you can see his analysis on his 
QRZ.com web page.)  Alas, a storm brought the dipoles down and the tree 
supports with them.

Re: Topband: ARRL CW Contest

2020-02-16 Thread Mark Lunday
Due to other commitments, I only had an hour on Saturday evening to do S on 
Top Band for the contest.  

Signals from EU were not that strong, but the band was quiet.  

With just 100 watts and a less-than-ideal inverted L installation for xmit (HiZ 
array for receive), I was able to work 24 stations in an hour.  That's credit 
to the band and the very good CW ops in EU who were able to copy my weak 
signalseveral ops were very patient and did not give up in spite of some 
deep QSB on my signal.

I also witnessed some superb CW operators...a lot of respecting the DX calling 
a specific station in response to his CQ; this patience by US/VE hams is a 
tradition with top-band and it's nice to see it in action still in 2020.  

Although it was only an hour, I very much enjoyed my contest time and am 
re-energized on top-band.

Topband: New Modes, Systems, etc

2020-01-11 Thread Mark
Wow Roger, people jammed repeaters for the autruistic reason of saving
amateurs from themselves? Let me give you two other more likely reasons for
this and why people belittle FT8 (the first of which you allude to in your
email):

1. "I had to do it the hard way, so should you" ; and
2.  They were/are concerned their achievements would be somehow be diluted.

These arguments were no doubt also used when the CW requirement on HF was
dropped and SSB took over from AM.

I find it incredibly sad the tolerance on this list is such, people felt
they had to set up a new reflector to discuss a 160m topic. Whatever
happened to the delete key?

I am also reminded of a quote from the late physicist Stephen Hawking:

"Intelligence is the ability to adapt to change."

73
Mark ZL3AB


It's easy to appreciate why many people - who are passionate about the hobby
- get upset about some of the things they see as being very negative to the
hobby.

Here in Britain there were LOTS of well-respected Amateurs who were actively
involved in Jamming the VHF Repeaters when they first came on the air in the
1970s. I would never have done such a thing, but I appreciated why those
people were concerned about it having a negative effect on the hobby.
People could now not bother to put up a decent antenna for 2m, yet work
stations 50 miles away.

However, most new amateurs that did that very quickly got bored with the
hobby, as there was no sense of achievement, no reason to self-improve . . .
and disappeared off the air.  Those that got the satisfaction of working
stations further away through their own efforts were usually the ones that
sustained interest in the hobby.

(It's interesting that there is almost NO activity on the various Repeaters
here in Britain these days . . . which kind of confirms my point!)

I think it's the same logic that many of us apply to the computer-based
modes/protocols . . . that there is no skill involved, and so no real sense
of achievement, like there is when puling a really weak DX station out of
the noise . . . with the result that those people will very soon lose
interest in the hobby.

So those of you who are so keen on them, please at least understand our
motives . . . it's because of our passion for the hobby that we are against
these computer-based modes . . . in the same way as I personally am against
VHF Repeaters or accessing remote Transmitting or even Receiving sites.

Topband: Propagation observations

2019-12-18 Thread Mark Lunday
Not trying to agitate, just making an observation about 160 meters.

If I can easily copy FT8 signals  coming from EU on my simple inverted L at my 
North Carolina QTH a full 80 minutes before sunset on 160, is there any reason 
why I should not be able to make a CW QSO?

I always followed common wisdom from others on top band (and mostly for 80 
meters)...if the sun is up, DX is nil due to ionospheric absorption (VA2GU 
exceptions notwithstanding).

But I was copying EA8DO at 2020 UTC today, and not ESP...I could occasionally 
hear the audio tones.  So why can't I do a CW QSO?

And then there's the skewed long-path from US NE and Canada to VK6 that has 
been workable daily on 80 meter SSB.  Since JULY!  Thanks to K2RR and VA2GU who 
clued me in, and I was heard on that path in VK6in July.

So I am starting to listen BEFORE sunset on 80 and 160.  The mystery continues, 
especially with a spotless sun.

2019-12-15 Thread Mark Lunday
I agree with you, Mike.   It would be interesting to survey the average age of 
our top-band subscribers (Tree, was this done already and I missed it?)

I started on top band in 2007, and really started chasing DX in 2009-2010 
season (it was a good one!)

But that was 10 years ago.  Between increasing demands at work, I hit the 
double-nickel this year, some health issues, problems with sleeping, and now we 
have acquired several four-legged children that we did not have before (rescued 
golden retrievers, rescued cats, rescued horse).  

Add in my time on the bicycle (not as much as I would like), and that doesn't 
leave a lot of time for ham radio.

One good thing about this is that my TV time has gone to almost zero...and my 
winter SAD issues have decreased because I am always getting outside; the horse 
gets daily visits and the golden retrievers will NOT take "NO" for an 
answerthey DEMAND a walk, sometimes two!  

I can remember in 2009, going on 3 hours of sleep many times during the 
week...and somehow being productive at work.  But that was a lifetime ago, work 
is a lot more demanding these days.

Reminds me of a quote from a friend of mine:

Topband: ARRL 160 is upon us

2019-12-06 Thread Mark - N5OT

Greetings topband contesters,

If you like 160 then you already know this weekend is ARRL's annual 160 
meter bedlam.


I had the pleasure of writing about it last year in QST:

https://contests.arrl.org/ContestResults/2018/160M-2018-FinalFullResults.pdf

And I guess they liked it enough to ask me to do it again.  This year, I 
hope for even more great photos and great anecdotes that get the 
attention of entrants from all walks of contesting and HF and CW and 
DXing, and make them feel like the ARRL 160 contest is one that is 
never-to-be-missed.  Maybe they ought to get on and give it a go for real!


So there are your marching orders.  Get on, have a great time, make a 
lot of contacts, but also:


Take some great pictures and make a few notes about highlights and other 
things that tickle your fancy.  I will be looking for the kinds of 
things that make for entertaining reading, and things that inspire 
others, like K9PG's great story about how he kicked butt last year

Topband: Hardening the 8 Circle Receiving Array

2019-10-17 Thread Mark Robinson
I  have the DX Engineering 8 circle receiving array sized for 80/160m . 
It has been a fantastic performer but I have suffered damage to the 
active antenna amplifiers on two separate occasions due to nearby 
lightning strikes.


I am looking at a way to protect these amplifiers.  I was wondering if I 
can add a pair or  dual series pair (4 diodes in total) of back to back 
diodes - say 1N3600,  across the input to ground terminals on each 
amplifier.  Will this affect the performance of the array in any way ?

2. adjust horizontal wire length back to desired freq.

Re: Topband: BOG questions

2019-08-25 Thread Mark Lunday
OK, my wife now is convinced that I have a screw loose in the brain somewhere 
(she had plenty of evidence before but decided to give me the benefit of the 
doubt until today)I just spent an hour in the hot North Carolina sun, 
wearing jeans and a heavy winter jacket so that I could wade through 300 feet 
of neck-high thorns and nettles and tamp those down so I could re-lay the 
insulated BOG wire.

I do this for three reasons:

1. I want to confirm the theory that growing grass/weeds around the original 
installation 11 moths ago have compromised performance

2. A nearby lightning strike Friday night wiped out something in my HiZ 
4-square receiving array, and I refuse to use the 160 meter inverted L for 
receive, even though this is a quiet QTH.

3. Even at my age of 55, I find sudden surges of energy when involved with such 
projects.

I shall share my observations as the nights progress, while I 
investigate/diagnose/repair/replace the damaged parts on the HiZ array.

Re: Topband: BOG questions

2019-08-24 Thread Mark Lunday
This is interesting.  Thanks for sharing, Mikek.

I put down 200 feet of insulated wire BOG pointed at EU, just set it down on 
the ground...sometimes over a fallen small tree but almost always within 12 
inches of ground.

I fed it with 75 ohm TV cable.  I did not terminate it, and I used a KD9SV 
transformer and added a pre-amp right next to it.

It picked up EU signals sooner than my HiZ or dipole at 60 feet that was 
broadside to EU.

It worked on 80, though not as well.  On 160 it was highly susceptible to AM 
BCB.

I started listening in October.  Something changed in March.  Suddenly it went 
deaf.  Not sure if it was because of all the rain in the winter, or the 
sprouting of the grasses.

I have not been out into the field, because it is covered with thorny bushes.  
I already ripped up and scarred my shin badly when I moved 2 of the HiZ 
vertical elements in April.   It was not painful, but it looked like my shin 
was in a knife fight or that I was attached by a big dog.

Anyway, I am wondering why the bog went so deaf suddenly.  I will try it again 
when we get into November.

Semi-Interesting post,  but not really applicable to the issue at hand.

>> To me, the guys who really have a beef are the guys from after WW2 until
the computer era

I have 4 patents in software engineering.I've been doing software since
about 1978 when I worked as a research assistant in my undergrad years.
I'd be delighted to put my experience in software engineering and computers
next to yours or anyone else's on this list,  but I'm pretty sure it's
quite beyond the button-monkey level of knowledge required to use FT-8.

>> Hank Aaron didn't devalue Babe Ruth.

No he didn't, but I suspect he tried VERY hard to beat his record.   Both
Babe Ruth and Hank Aaron used a bat, ball, and gloves.That was a pretty
level playing field. Perhaps one day we'll have robot ball players
mixed in with humans.Do yo think that will fly?Of course, closer to
home,  we're now seeing where transgender issues are effecting competitive
sports. Competition needs to be equal,  and there's nothing to prevent
different levels of competition,  but equality and fairness must exist
within the same level.

As I mentioned in a related post while I was /HH6 in May,  my FT-8 oriented
friend initiated an FT-8 sequence,  went to the bathroom,  and after coming
out pointed out he made a QSO while in the bathroom.  He specifically did
that to show me it could be done. And FT-8 people want respect for
that?Sorry Charlie,  not from me.

You said " Yes DX last year on 160 CW was pretty scarce" and other have
made a similar comment.

Are you referring to new ones, or just DX in general?I worked 16 new
ones on CW last season and understand that "scarce" can be different
depending upon how many DXCC one already has worked.

Dave, that's interesting.

If I remember correctly, there was a data buoy floating in the Pacific with an 
HF rig on it.  Hams could call the buoy and work it on FT8.  Because it 
reported grid location, callers could work different grids as the thing floated 
with the currents.

>>Can't we get along?

I doubt I'd like to get along the way you want us to get along,  by
suppressing discussion because you don't like it.   You want tolerance
based upon indifference, and that's wrong.

I would posit that most people on this reflector have a passion for 160M or
else they wouldn't be here.   Just because you don't like someone elses
opinion of a topic does not mean it should not be discussed.By virtue
of the fact that this topic comes up periodically points to the fact that
there is deep concern and non-aligned opinions on it and it's smoldering
under the surface..As long as it's discussed in a civil manner,  it's
fair game.

Why don't the people that don't want healthy discourse just delete the
respective emails, or unsubscribe from the group?It's just that easy.

If my opinion offends anyone,  that's too bad.   Nobody has the right not
to be offended.

“Cheating” is a strong word.But to address it, just because someone
cheats on mode A does not mean we ignore cheating on mode B;  it should be
addressed on both.

FT-8 is another disruptive technology that is here to stay,  and one where
our alleged “national organization” has failed to provide guidance on it's
impact on the competitive aspects of Amateur Radio.Like someone else so
aptly put,  you don't have a race between a person on foot and a race car.
That summed up this entire issue eloquently and sufficiently.

Re: Topband: RX antennas comparison chart

2019-07-31 Thread Mark Lunday
One more vote for the HiZ.  

I have the four element since 2012.  It's NOT a perfect installation at my 
QTH...trees all around, not that far from the fence.  I'm in central NC, clay 
soil, with 50 kV power lines about 1/8 mile away to north.  But it works, and 
works well even with my compromised setup.  

I have recordings to support my conclusions about its performance, DX that I 
have heard and worked.  

The complete package cost me about $1300.  That's turnkey, everything included. 
 Easy setup (if I can do it, anyone can).  

It was not cheap.  But I did not have the room for the long beverages and I 
really wanted to work some serious DX on 80 and 160.  And I have.  Worth every 
penny.  Excellent quality.  Technical support was (and is) fabulous.  No 
regrets.  


How good is the system?  Two weeks after installation, 14 December 2012, I 
worked XU1A on 80 meter SSB long path.  No-one else could hear him well enough 
for a QSO.  Transmit antenna was an inverted L with 300 watts.  That's a real 
golden nugget in my logbook from the past 42 years of hamming.

Hi Jeff

Your concerns are shared by a lot of us.  I made the same observations
about 10M several times this summer.   As you said, it the way things are.

I have 147 countries confirmed on 160M (all CW).I’d really like to get
to 160 confirmed (CW) on 160M before the proverbial well starts to run
dry…..

Re: Topband: Transmit High Pass Filters for BCB Interference

2019-07-30 Thread Mark K3MSB
Thanks for all the replies.   My friend is probably going to go with a DLW
custom filter.   I'm embarrassed that I forget about the common mode choke
as I use them here on all bands especially 160M.   I told him I'd help him
build one.

Re: Topband: Transmit High Pass Filters for BCB Interference

2019-07-29 Thread Mark Schoonover
Mark,

I had the same problem - I live a mile from 760 AM at 50KW 24/7. I used a
homebrew highpass filter and that helped but didn't quite reduce it enough.
What I figured out was the signal was also on the coax braid! I put two mix
71 toroids, wound 6 turns of coax through them as close to the rig as
possible. Made a huge difference in interference. The signal went from 60
over 9 down to a manageable S8 on the fundamental. Harmonics don't fall
into ham bands so not worried about them. Mostly I suffered from severe
overload and distortion across the low bands.

HTH

Topband: Transmit High Pass Filters for BCB Interference

2019-07-29 Thread Mark K3MSB
A friend of mine in our local radio club sent me the following email

"I'm 6/10's of a mile from an AM 910 KHz. transmitter. They operate with 5k
daytime and 2k at night.

They're S9+45db on 160 meters with clear audio and S9+35db on 80 meters.
have an inverted "V" resonant at 3.715 MHz. orientated east-west, towards
their reflector tower."

The station is willing to pay for a filter for my friends station,  and he
has looked at notch and band pass filters but has concerns.

I recommended he look at transmit high pass filters to knock out signals
below 1.8 Mhz and provided him with various links:

https://www.dunestar.com/store/160-Meter-Highpass-Filter-pid-8.html

http://www.kf7p.com/KF7P/Morgan_Filters.html

https://www.dxengineering.com/search/part-type/transmit-high-pass-filters/product-line/dlw-associates-am-broadcast-band-brick-wall-high-pass-filters?autoview=SKU=Default=Default

I have no practical experience with any of these filters and was wondering
what the TB Gang thought.

He would prefer one that handled 1.5 KW but I told him he may have to
settle for 200W.

He prefers an "out of the box" solution.

Terry, I strongly encourage you to put up the K9AY. By no numerical measure is 
it the best. But it’s easy to put up and Compared to all the others, it is 
relatively insensitive to other objects around it. And for a first RC antenna, 
it is super satisfying to click between directions and hear stations in the 
null disappear as proof of directivity.

Interactions with other antennas is a “big station problem” and you or I won’t 
notice what bothers the big stations.

Hi folks,

I have four kits purchased on ebay for receive antennas as well as a bi-directional 
beverage from KD9SV. Looking on my county plot map it looks like I can run about a 412' 
beverage using my neighbors ground and mine. Got a good neighbor you could say who just 
doesn't want a BOG to trip on but a beverage not too low to walk into is Ok. My ebay 
provided kits are DHDL, EWE and Penant/flag/diamond from a low cost Canada source. But 
I'm faced with the problem of fences, power lines, roads and my TX antennas on my 1 1/2 
acre plot. If one of those antennas could handle being near the fences,etc or TX antennas 
I'd like to hear about it. I've already got a K9AY in the works and that one is near my 
40 meter 4-square. Running the beverage is going to be near or even under my K8UR style 
80 meter 4-square made with 1/2 WL slopers. I've thought some about converting the 80 
meter 4-square to using 3":irrigation tubing extended with some 3" irrigation 
tubing and a coil at the elevated base but I'm j
ust not sure if it would be an improvement. It would be near 50' verticals if I 
could do it. Not sure if I would lose too much gain.


Any suggestions other  than 'give up'? I've always had a time hearing the DX 
especially on 160 meters.

the relay boxes for multiple Beverages, and the broadside phasing boxes are

Topband: FCP vs Gull Wing Elevated Radials

2019-07-25 Thread Mark K3MSB
This kind of goes with the other thread that has morphed into the FCP
topic, but is a bit different.

With an FCP feeding the INV-L,  the bottom of the INV-L will be at least 10
feet off the ground.With my existing trees I can barely get up 50 feet
from the ground.   So, the INV-L will have 40 feet of vertical radiator.

Using a pair of resonant gull winged radials feeding the INV-L at the
base,  the vertical part will be 50 feet.

From what I’ve read,  the FCP is a better solution over a pair of resonant
gull wing radials,   but I’ve also read that vertical length of an INV-L is
important.   So there’s a tradeoff to be considered.

Comments?

Due to real estate considerations,  I can put up only 2 one-half wavelength
resonant radials
