Re: Topband: The "new" Topband

[K9FD]

During my 22 years living on Molokai I was very active on 630,
first with experimental license, then with ham when it opened.

worked VK, ZL, JA, All of USA, South America, ZF, KL7, VE etc etc, 
received reports

from many others including Europe.  All with 1 watt into the antenna.
I moved back to K9 land Jan 2022,
I used my 160m Inv L with a large variometer at the base to tune it,
had 120 -  350 ft radials and 120 - 60 ft radials so no lack of ground,
about a mile or so from ocean on 3 sides.  Former 50kw KAIM BC station 
location

about a mile from the old Loran installation on Ilio point.
yes tried 630.
73Merv K9FD

Colleagues,

Have any of you attempted to get on the 630 meter band?

As a US Coast Guard radioman in the 1970s, 500 kHz was the worldwide
maritime CW calling frequency; almost all night-time traffic occurred
on 600 meters. While stationed at Coast Guard Radio Honolulu (NMO),
I'd copy stations Pacific-wide -- from Alaska to Australia, from the
US west coast to Asia. Just incredible coverage sunset to sunrise.

(Daytime traffic shifted to the 6, 8, 12, 16, 22 and 26 MHz maritime bands.)

Re: Topband: Suggested Frequency

[K9FD]

When I purchased this property in Hawaii,  there were two 830kc towers 
left from the
KAIM 50KW station.   I made a matching network and loaded up for the 
Stew perry,
only had my exciter so ran low power,  if I remember correct I was 
number 1 low

power world wide..  but my memory is corrupted so would have to look it up.
Tower radiated very well and I only had it to receive on as well.
Location Im sure is part of it,  but I remember at the time all advice 
was against even

trying.
Worked for me.
I gave the feed point info for 830KC to a top band guru and he gave me 
the L and C
needed for 160,  his figures were dead on the money.  Did not even need 
to tune it.

73 Merv K9FD
Our club is working on a project where we will be able to use a AM 
Broadcast antenna on 160 meters.


Don't get your hope up. Roughly 40 years ago, I did that, along with 
another ham, at a daytimer for which another ham friend was the chief 
engineer. As I recall, the station was around 830 kHz, and was in a 
northwestern Chicago suburb. We had no problem loading the tower, but 
couldn't hear a bloody thing, even after trying to rig a Beverage the 
second night. Zero QSOs.

Re: Topband: 80 and 160

[K9FD]

!60 has been open over the pole here for a few days,  today no 
exception,  usually can work
20 to 30 contacts,    mostly North EU,  Russians,  and of course Asia, 
VK, this morning A71EM
called me with a great signal 599.   I tuned up to 20 meter after 
sunrise and EU signals were

the loudest I have heard in some time,   interesting conditions.

Ron et all

Same here not the first DX station at our ( FL ) Sunrise. I called a 
couple of times and did not even show up in VK/ZL on PSK Reporter 
which I usually do at sunrise. I then slid up to 80 and there were 
JA's a VK's and then I got called by a YC8 for a new on one 80 . Guess 
the LUF was 3.5 MHz. About 3 hours later EU was booming in in 15M ..S9 
signals all over the place Loudest I have heard 15 in years...a sharp 
MUF cutoff not a peep on 12M ..Odd condx all around

Re: Topband: Good conditions, Little Activity

[K9FD]

I lived in BY back in 1999 and 2000 and put BY1QH on 160 even before 
that time,
Problem is not the stations or antennas,  its the noise,  hardly any BY 
live in the
country, they are mostly all stuck in town and the noise is something 
you have

never heard the likes of.
I operated weeks on end and the noise never got below S9.  most times 
was even

higher.
I cant imagine what it is now 20 years later with  all the new 
appliances.  Yea and these
are the appliances and junk that we complain about a neighbor using, 
made in China,
multiply that by thousands and you get the idea.  Plus a electric grid 
that has so much

coal soot on it that it arcs all the time.

I have it easier here in KH6 being closer,  I hear many BY on the band, 
both CW and FT8
and even with 1500 watts and being closer its difficult to work some of 
them,  if your

signal is not over S9 your out of luck.
Most Asian stations are in the same noise boat,  I have operated from a 
number of places

in Asia and its mostly the same,  S9 noise.
US is not far behind on becoming noise limited,  there are charts that 
show noise increase

over the years,  not a good outlook.

73 Merv K9FD  Molokai Island Hawaii



 If we could just teach the BY stations CW and station construction 
practices for 160m we would be in good shape!


The good news is the end of cycle 25 is sounding a lot like it's 
predecessor. I'm definitely looking forward  to the winter months. 
Anything is better than nothing.

Re: Topband: Beverages and VK

[K9FD]

Did you try all the other direction beverages you have?
In the past 20 years of operating here in KH6 I find many times
EU comes through over central america, not over USA, and its
hard as heck to tell EU to listen that direction.  Same with signals
from the northwest,   I hear  lot of stations coming from the west instead
of northwest etc.   very skew path.
so switching to a dipole helps,  not with angle but with direction,
if one had a beverage on that skew path one would find the beverage
works quite well.
Lot of variables and as they say you never have enough antennas for
receive.

73 Merv K9FD  Molokai Island Hawaii.


Interesting observations with dipoles and high angle of arrival at
sunrise/sunset. But from graphs, the beverage also has a fairly high
radiation angle.

I am wondering whether anybody has compared beverages on 80m with RX
vertical arrays or transmit 4 sq. On 80m, my Beverages are a bit
better than 4 sq for DX.

Re: Topband: RG-6 Delay cables

[K9FD]

Ever see RG6 with a solid aluminum shield?


One thing that hasn't been mentioned here is how the aluminum shield,
jacket, and dielectric behaves.  I'm pretty sure that the CoE/°F of
aluminum is *more than twice* that of copper and steel.

I am speaking specifically about a solid aluminum shield bonded to the
dielectric.

Braided shields would of course expand and contract with the rest of the
coax.

Also, many cables also have the center conductor bonded to the dielectric.

I am not disagreeing with anyone; I just thought that I ought to throw that
into this discussion in case it matters.

Re: Topband: 9 circle RX array combiner board

Many of those Chinese ones are plain junk,   if you measure them they re 
no where close to a
good 5109.    They just silk screen the number on the top of "generic" 
parts.
If you use them test them before putting them in use,  will save a lot 
of trouble shooting time.


I bought a supply from Mouser a month or two ago,  they had some on 
order,  probably all gone

by now as the word gets around.

Hi Rick,

Yes, the 2N5109s are almost un-obtainium now, but a few months ago Mouser 
stocked them and maybe DigiKey, but now they are out-of-stock. Even the 2N3866 
substitute is hard to find.
Over the years (2 decades) I have built at least 10 of these amps, and still 
have a supply of a dozen or so 2N5109 devices, and since these devices are 
almost indestructible, I’ll likely never run out! You are correct that this is 
a problem with this design.

Thanks for the E-field amp link….nice…perhaps another project to build!

I like KiCad a lot. super easy to learn. I had never use a PC board program, 
but I was able to learn KiCad from scratch in one evening!

de steve ve6wz




Now I know why you work stuff I can't even hear :-)

The 2N5109 is just about extinct. Did you secure a
source for it before you laid out your PC board? If
you did, please share it with the rest of us. Most
people are now using substitutes for the 2N5109 with
varying degrees of success. Are you possibly doing
that? Of course those substitutes are not in a
hermetic metal can, so the PC board has to be laid
out for differently for them.

You might want to look at these references for
so-called "E-field" arrays of whip antennas:

You also find a lot of other good stuff on Chris's site.

They go beyond the DXE design.

Good luck with your project.

BTW, how do you like KICAD? I'm currently using a grandfathered
EAGLE 7.7 perpetual license, but "some day" I might switch to KICAD.

Re: Topband: New Modes, Systems, etc

[K9FD]

Was there not another list started for FT8 on topband??

Why the heck is this stuff still here then??




Roger,

If you are so confident that digital is going to fail, why not sit 
back and let it happen?  I have never figured out why people in the 
hobby would actively seek to push people out of the hobby. What I find 
most interesting is that those trying new things and experimenting 
never seem to "attack" those that don't.  Why is that?


Like all hobbies people come and go for their own reasons.  There is a 
hell of a lot more to the hobby than working people on AM, CW or SSB 
on HF, chasing DX, contesting etc.


As for your 2nd to last paragraph, those are your opinions.  Those are 
not facts.  There is skill involved.  There is a bunch of excitement 
and achievement.  You just keep repeating the same old things to make 
yourself feel better.   Congratulations to your old guard in England 
for being able to run people off your repeaters. That is something to 
be proud about?  Wow!    The ARRL RTTY roundup ran recently and FT/X 
and other modes were allowed but those modes or types were never 
really pushed. 
https://3830scores.com/currecscores.php?arg=01cgsXz7mgcyx  Why don't 
you click the link and see how many people used digital? This list 
only those that know about 3830.  Yes RTTY is the champion by far but 
it would seem to me that a lot of people sure had fun digital.


I understand you don't like.  FT8 users got that long ago.  I know 
plenty of hams who will never get on CW but I never hear them 
criticizing it or even thinking about jamming things they don't like.


In the USA this is what Ham Radio is according to the FCC.

§97.1 Basis and purpose. The rules and regulations in this part are 
designed to provide an amateur radio service having a fundamental 
purpose as expressed in the following principles:
(a) Recognition and enhancement of the value of the amateur service to 
the public as a voluntary noncommercial communication service, 
particularly withrespect to providing emergency communications.
(b) Continuation and extension of the amateur's proven ability to 
contribute to the advancement of the radio art.
(c) Encouragement and improvementof the amateur service through rules 
which provide for advancing skills in both the communication and 
technical phases of the art.
(d) Expansion of the existing reservoir within the amateur radio 
service of trained operators, technicians, and electronics experts.
(e) Continuation and extension of the amateur's unique ability to 
enhance international goodwill.


I think many have lost sight of this.  Encouragement is not telling 
people that FT8 sucks, that you have no skill, it is not ham radio, 
nobody will stay with it etc.  It is certainly not about jamming 
people out off a repeater.


Where is your goodwill?  Instead of constant criticism of the modes, 
where is the reaching out to others to try CW or SSB or some other 
parts of the hobby?    All I see is oh you run X  Get out of here.  I 
find it extraordinary that somehow you can tell someone what will be 
exciting to them or what is an achievement to themor what takes skills 
and you don't even know them.  What is wrong with Ham Radio today?  This!


Anyway we have our own group of nearly 100 people in less than a day.  
We will continue on in a friendly fashion and will have fun and if 
FT/X dies so be it.  I bet something else might come along to replace it.



I get a big thrill out of working any DX on 160.  CW or FT8 or SSB.  
It is hard from Colorado even with fairly decent setup.  I can work DX 
on FT8 on days I never hear a thing on CW.  You have lived your life 
next to a nice salt ocean very close the population center of the USA, 
not to mention how close you are to so many other countries.  Topband 
for you is very different than the Topband I have.  Working states is 
similar to your working DX in Germany or Sweden and even Africa and 
parts of the middle East.


It saddens me that owner of this list has similar views to yours 
Roger.  Tree was one of the guys I looked up to as a young contester.  
He was one of the first to push the envelope with a Sweepstakes Robot 
and really helped with log checking and so many other advancement in 
Contesting and the hobby.  It is sad that some can't be accepting of 
what others do.  It is sad that we had to create another list because 
people could not be civil.

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.

Re: Topband: Possible 160m propagation indicator: lightningmaps.org?

[K9FD]

Conditions on LF and MF last nite were nothing special,  the nite before 
either,
but two nites ago 630M was as good as its ever been since I have been 
using it,  I

have been on since about 2013,  starting with an experimental call WH2XCR.
I use WSPR overnite to record conditions and activity,  for the first 
time I copied

G0MRF and LA8AV on 630M,   and was reported by LA2XPA and a Norway SWL
KQ40LS,   received reports from JA. VK, ZL, LA, US mainland, VE etc 
running 1 watt erp.
So far I saw no coorelation between lightning propagation and conditions 
on 630M.


I did notice on 160 meters yesterday that Vk and ZL were stronger here 
than any locals,
a couple UA9-UA0 also super strong, at my sunrise that is, but the EU 
conditons were poor compared to

previous days.    Today was generally fair but signals all back to normal.

This winter season on 630 meters I usually will copy 20 to 30 different 
stations and will be reported

heard by 60 or 70 unique stations.

73 Merv K9FD  Molokai Island Hawaii


Mike,

Thank you for the post, very timely for me.

I have been exploring the VLF and LF spectrum (RX only) for a few 
weeks now, after spending some time and money acquiring the capability.


As far as hamradio goes, there is life in the 2200 and 600M bands.

Regarding lightning strikes and their effects, yesterday was an 
interesting day. Keeping in mind this is all news to me, I was 
surprised to see the number of 'hits' on my SDR waterfall. It was like 
every 10-15 seconds or so. The SDR would go into clipping for the 
duration.


This went on for a few hours, nothing was being decoded, and then 
quiet. G0MRF in the UK, and other NA stations, showed up again on the 
monitor a few minutes later on 600M. I did not check 160M, will do 
next time.


I did not see any mention of yesterday's condition on the VLF list 
though. There are ongoing attempts on 8.270 kHz and less frequently on 
1.65 kHz. Fascinating stuff.


Thank you for the links.

Re: Topband: Activity

A5 guys were on both CW and FT-8 this morning,  signals that direction 
not too good it seemed.
There was decent activity on CW and FT-8 was unreal,  today the band was 
open over the pole,
not skew path,  right over the pole,  and say what you want,  it was 
shades of 2008-2009 era.
Tons of Eu and Russian Eu/Asia,   QSB was fast and deep,  one second 
would be +0 and next
transmission it would be -20.   Worked a number of stations, but had a 
blast listening to KL7SB
he came on and there were 10 to 15 callers at a time, he was giving good 
reports and this
continued for some time,  he was still going at it 30 mins after sunrise 
here,
Myself I could still work EU on QSB peaks 30 to 45 mins after sunrise.  
One of the memorable

160 openings.
I am hopeful next season will be even better,  I think the lowest is yet 
to come,  and even perhaps

2021 before the upturn starts.

Conditions were moderately good last evening (NA time) to Europe.  I got on at 
my SS and then again later in the evening and put 32 EUs (CW) in the log 
including some call signs I’ve not heard from in several years.  The A50BOC 
crew have been active and are trying hard on the low bands.  This morning they 
were QRV on 1826.5 (QSX up 1) and 1836 on FT-8 somewhat taking turns with 
modes.  About four NA stations that I’m aware of had success on CW.  They were 
also on 7002 and 60m (FT-8 I believe). . .so they’ve been busy and are clearly 
making a serious effort.  They have been working on improving their Beverages.  
Good luck to all who need them.   73. . .Merry Christmas/Happy

This morning conditions were close to, not quite as good as 2008 era.
A5 was a good signal drawing a big crowd,  4S7 good signal even after

lot of Asian Russians,  EU Russians,  EU from north to G, F, SV, etc 
copyable,

EA8ZT called me with 599 plus signals just after my sunrise,  lot of good

Flash Gordon must have had his ray shield in place and deflecting them into

From my morning 160 monitoring for the past month or so,  it has been 
pretty

decent conditions on and off.
The death of the band is greatly exaggerated,  you just have to check 
both ends

of the band to find the activity so to speak.
If this continues,  would hope next season to be close to 2008 era.

should get your hearing checked.  I have crappy hearing and it was no 
problem.

Let me take a guess. It had to be one of those 'make believe' inaudible

Re: Topband: BOG Beverage on Ground Help

[K9FD]

WOG  wire on the ground


I agree with Bob. I think the name BOG is firmly entrenched, whatever the
electrical differences. Oh, I could propose a new name, but I doubt it
would ever stick.

I'll go back to my Otter/Platypus to propose a parable:

Suppose that the Platypus had instead gotten the name of Duckfaced Otter,
and that was firmly entrenched in the language regardless of the science
placing the Duckfaced in a different Latin-worded species.

Then on a reflector, an argument crops up, someone says that the Duckfaced
Otter lays eggs. Others deride that statement, saying everyone knows that
an Otter is a mammal, that mammals give live birth and Otters do not lay
eggs. Some, quite irritated, ask wouldn't the Duckfaced Otter have been
named differently if it was really that different? Probably because it was
named centuries before people knew it laid eggs.

In the science, the egg-laying, out of many differences, all by
itself would put the Duckfaced Otter into a different species, because such
differences are what define different species. Overall, most already know
that the Duckfaced Otter only *looks* like an otter, really isn't. But they
still call it the Duckfaced Otter because that's what the language calls
it. Who among us ever gets to successfully take on the language?

---End of Parable---

Beverage   Otter

On-ground Beverage Duckfaced Otter

Both are a longish  Both have brown
wire parallel to earth,  water repellent fur coat.
only used for RX.and love the water.

Isn't it really about time that the masses on the reflectors know that a
BOG has irritating issues that no up-in-the-air beverage has to design
around, but must be taken into account designing a BOG? That any Beverage
strategy has to be analyzed laying on the ground to see if it really
applies to a BOG?

The antenna category is Ground Low Velocity Factor. The short for that
could be GLVF, except we already call those -on-ground or OG. Dipole on
Ground is a DOG, Loop on Ground is a LOG, Beverage on ground is a BOG. In
this system "Beverage" is only one possible shape of the wire laying on the
ground. How a BOG behaves and how to engineer/model one is really only one
application of how OG behaves and how to engineer OG.

I think OG is just fine. I don't think OG needs a new name. Just remember
that BOG is only one shape instance of OG, and OG controls the engineering.

Re: Topband: Odd (?) Propagation this Wednesday AM

[K9FD]

Yesterday ayem  5H3 was on for over an hour,  he was -10 here yet an 
hour and half after sunrise,

he had peaked several times around sunrise at +0
This morning was 3B8M on for a couple hours,  same thing, copy great 
after sunrise,  as was VU2

and a number of others.
JA of course very strong as well as UA9 etc.   heard a few EU stations 
before sunrise.

So far so good on the low cycle.
73 Merv K9FD,   Molokai Island Hawaii



I went to bed the 2nd time last night around 0900Z (not much to show 
for my 0700-0900 2 glass of water alarm. I decided to leave the 
computer and rig on 1840 listening to dreaded drone of the FT8 bees. I 
slept in and didn't get up till 1300Z an hour after my sunrise, 
Scanning the JTDX record to see what I had missed I was surprised to 
see decodes of a JA and 3D2AG almost an HOUR AFTER my sunrise !. There 
was indeed the sunrise bump  where I also copied those two stations 
which lasted about 10minutes , Then about every 15 minutes the decode 
log showed the JA and 3D2 they would pop in for single decode and 
sometimes 3 or4 before dropping out again

Topband: VU2 on top band

[K9FD]

I have worked VU on top band just before their rules changed and they were
not allowed to use freq around 1840,   today I worked VU2 on top band again
and he was on 1840.   I wonder if any one knows if the rules have changed
again and they are allowed to use those freqs.

One thing I notice "that" mode is good for is watching for peaks and 
nulls in
received signals,   I hear a lot of folks saying they are not seeing 
sunrise and
sunset peaks,   I see them as I have for the past 50 plus years of 
operating top band.

I watched today as the VU2 went from -20 at 1634Z to -13 at 1650Z, my
sunrise is 1646Z,  so there was a definite peak at my sunrise as there
normally is.   I also have a peak about an hour before sunrise normally,
Sunset is the same,  signals peak at sunset and again an hour after.

I was hoping to catch 5H3 on top band for one of the two last zones for
WAZ from this QTH.   But heard or saw nothing of him.   I think I have a
shot if he would hang around until my sunrise.   But not to be.

Re: Topband: 160 status this am

[K9FD]

I work 630M also, last nite at 0830 I checked my WSPR log and was copying
JA1PKG,  so I had a good idea that 160 at sunrise would be a good bet.
When I fired up before sunrise I worked H40TT barefoot while the amp was
warming up,  did not hear much on CW and I noticed some big signals up
the band on FT-8,   sure enough the band was wide open and full of signals,
from 4s7AB to VR2, all over Asia,  tons of Russian UA9, UN7 etc etc and good
signals from SM, LA, DL, LX, S58 etc.   Worked over 20 stations in short 
order.

sounded like the 2008 era when I could work 40 or 50 EU easy on the sunrise
path.  Its looking good,  I saw spotted 5H but was late arriving and 
heard nothing,

that would be one of my last two zones from this QTH.
Sounding great so far, should improve as the season progresses,
73 Merv K9FD   Molokai Island Hawaii

Having hooked my inverted L yesterday I woke early (not on purpose) so grabbed 
some coffee and turned on the radio. I could hear JA from Ohio on the Hi-Z an 
hour before my sunrise. Called a few times to no avail. 15 minutes later put 
two JAs in the log. Heard peeps of some other Asian stuff but no real copy.

Topband could be good this season!

Re: Topband: Impressive demonstration of one dB of signal strength improvement

An excellent article is in an old QST called "station design for DX"
It mentions that 1 DB improvement in the station will provide a whole
new layer of DX signals.   Very true.

In the average station you can easily find several DB that can be 
gained.

If your into DX think of all your missing.

audio files by recording typical band noise and then overlaying them
with recorded CW messages at various strengths. The difference between
1 dB above the noise level and 2 dB above the noise level can make the

Re: Topband: AM interference on 1840

[K9FD]

Boy that is pretty extreme,

When i bought this QTH I had a 50KW AM station on 830khz blasting away in
the other room from my shack.  Near impossible to operate,  most any band,
later the 50kw was moved and power dropped to 1 KW,  that was not much
of a problem.   Then the 1KW was moved also, all is fine now except for 
mixing

products from junk mixers on a set up in Oahu that runs 4 transmitters on
one tower,  3rd world stations that do zero maintenance and the whole set
up is rust and paper clips.   they put a signal every 10 khz from 
Broadcast band
to 80 meters,  and raises the noise floor on 160-80 at least 10db 
besides as it

"splatters".
Numerous complaints filed to FCC is like peeing in the wind. There is no FCC
locally here in Hawaii any longer, due to reductions in staff and 
engineers,  so anything

goes.

Merv K9FD  Molokai Island Hawaii

Yeah sorry got frequencies flipped. Notch on 1860. See what happens. I 
live a mile away from 760KHz running 50KW 24/7. I use a W6LVP RX loop 
with one of his BCB filters in it plus another BCB filter right at the 
rig input. This reduces the signal from 60+ over to about S9.

Re: Topband: AM interference on 1840

[K9FD]

Explain how a notch filter on 930 can help a second harmonic on 1860?

You can filter the broadcast band to zero and the second harmonic is 
still there.



Mark, I use a receiving array and have put a high pass filter on the 
receiving array to cut the broadcast band down. I have an AM station 
near here that was doing the same thing.  If you can run a separate RX 
only antenna it helps.  If not then a notch filter for 930 may work 
that you can transmit through.

I have a local AM station here (about 3 km away) that operates on 930 
kHz. Their second harmonic is 1860.  Seems they are operating within 
specification and abide by FCC regulations. But still the second 
harmonic wipes out any DX on or near that frequency. Signal strength 
is around S7.

Topband: 3B8XF

[K9FD]

After a few days of almost no signals heard on top band at sunrise,
I was going to sleep in this morning,  but knew better and forced
my self out of the sack at 5Am local.
Band was noisy but soon I heard CW and there was 3B8XF, slow deep
fades but peaking 579.   Thanks to his hanging in there he pulled me
out and we completed a QSO,  a new one for me on top band.
In a few minutes I tuned to FT-8 to check and there was Nigel again,
peaking -2 at my sunrise,  worked him for the digital contact also.
Thanks to Nigel for being on top band and having good ears.

Re: Topband: Topband V84SAA and ARRL Contest

[K9FD]

V84SAA was loud here again this morning,  saw them go to FT-8 and needed
V8 on digi,  they replied after a couple calls,  they peaked at -5 for 
an hour and a half

from around 1600Z to 1730Z.
They have been loud here of course on 160/80/40 etc.   great operators 
to hear

me during the EU pile ups and listening on the EU antenna.  On CW the op
replied to RK9FD at first and was surprised when I corrected to just K9FD.

Thanks guys for the effort,  good job,  of course from KH6 much easier 
than from

K1.

Tough tamales with the last shot at their
SS this morning on 160. Just as their
brief signal began to appear in CT, a WH6
contest station started calling CQ test
200 Hz above and though several sent QSY
to him, he insisted on staying put &
finally it became a debacle and I turned
off the radio.

I love contests but I always QSY when I
forget to QRL and start transmitting &
someone sends QSY. It's beyond me why
others don't do the same.

Good year for 160,  hoping they will return in the next couple years.

Hi Dave and all.
Cleaning my radio room but will keep a dear QSL card from year 2009 stating
two different QSOs on SSB, reports 59, 58 and one on CW stating 569 CW.
Oh, the card is from KH7C ex K9FD for a two way QSO on 160 between Sweden

This thread has been addressed on various reflectors.
I've tried it, made around 400 contacts or so, and found the mode pretty
boring.  Even with my pileups on FT-8 the mode left me cold.  I felt the
same way with RTTY...tried it and found it boring.  Why?  With CW SSB/AM I
felt a connection with the other person, someone sending with a key or a
person speaking to me.  With RTTY and especially FT-8 my machine is decoding
your machine.  Oh yeah, I know my XCVR is a machine and so is yours, but for
me it's not the same.
I understand why guys get all hot and bothered about the new mode, it gives
the guys who don't know CW a chance to work DX on a mode other than SSB and
gives the weaker signal guys a chance to work DX.  For the guys with bigger
stations it gives them a chance to work the rarer ones on tough bands like,
160 or 6.  Maybe that's why I'm not into FT-8, I've got a big station, and
can work CW.  Also, I've never been really into putting the new one in the
log as much as many guys are...I'm more of a contester.
If you want to work your pileups and/or work 300 countries on FT-8, that's
fine with me.  I'm not going to look down my nose at you but please don't
condescendingly  tell me I'm a dinosaur or refuse to accept new technology.
I'm accepting it, I just don't want to be part of it.  No hard feelings.

I worked a VU2 on 1840  on DEC 23 2018  so I assume that was just before
the new rulings.
Thanks for the new info.
73 Merv  K9FD/KH6


Merv and all,

We had 1820-1860 kHz in VU but a newly released National Frequency Allocation 
Plan has changed it to 1800-1825 kHz.

Talks are under way to try and get back the old frequency allocation but until 
then we will have to go low and work split on FT8 or other digital modes. 
Couple of folks are still using the old allocation based on their 
interpretation  :)

Putting up my 160 vertical back up today after my lightning hit in May, hope to 
work a few in CQ160.

Re: Topband: Inverted L improvements - Part 3 (now with data)

[K9FD]

Dont get discouraged by all this for sure

What I see as fly in the ointment is another 160 antenna close by with 
another

radial system,
Anyone of you gurus ever figure what putting power into a 160 antenna does
with another one within feet of it?   Imagine power going out, and right 
back

into the other one,  being burned up in loss..
Its like having a parasitic element sitting there and screwing up your 
entire

attempts.
Wonder why the SWR is broad,  your tuning two antennas,  any one who has
ever tried to tune a 4 square with all elements up knows it cannot be done
actually.

Take down the short 160 antenna or find a way to detune it far far from 
160,

and then take some measurements.

Come on expurts look at the whole picture not be tunnel visioned,

73 Merv K9FD

Both Merv and Guy are correct here. Perhaps this antenna doesn't ever
have a chance at being any good due to the suburban area and lot size
that I'm constrained by.

Within a 250ft radius (huge!) there is as follows: 80m dipole, 40m
dipole, 30m dipole, 20m dipole, 15m dipole, 20m yagi, and the original
43' tall T antenna for 160m and its radial system. Also, the house is
easily within 250ft.  Most certainly the radial systems, although not
physically connected to each other, are let's say "mingling".

So perhaps this tall wire was doomed from the outset? I was so
encouraged that the 43' T worked so well for what it was and the small
amount of effort it took to get converted to 160m that maybe a taller
version would be substantially better. That's how this saga started.
Maybe the real answer after time/effort/money expended and all of your
advise is that it isn't going to get any better in my environment?

At this point the best path forward may be to just remove the tall
wire and reroute all of the new radials (over 2000ft) to the original
43' T's radial plate and with any luck make it play better as a
result?

worked a number of stations, all the way down to EA6,  and
even DL an hour after sunrise,  several were still calling as
the band finally faded out,
This morning was a "typical" 160 opening of old,  there were good signals
an hour before sunrise,  faded out and then peaked much stronger
at sunrise and just after.
Was close to 2008 era conditions.
Antenna I was using was the transmit INV L as the RX antennas are down

A41ZZ and Vu2CPL have been on almost daily with very good signals.

Re: Topband: Accuracy of modeling of 160m verticals

[K9FD]

So true,  my AM broadcast station location with 120 330ft radials does 
not hold a

candle to the same InvL antenna at the beach with two radials.
I am about a mile inland from the beach.  Too far for any help.

73 Merv  K9FD  Molokai Island Hawaii

Hi Ignacy,


Salt water is very special! In a salt water environment potentially
the entire Fresnel zone -- where as much a 6 dB of gain is obtained
from ground reflection -- is in a highly conductive environment.

Low angle radiation from a vertical with a salt water Fresnel Zone
is much better than from an inland vertical.


In a inland location only a very small fraction of the Fresnel Zone is
covered by conductive radials.

A number of articles analyzed 160m verticals by simulation. Once the height
was lambda/8 and the number of radials >= 16 (buried) or >=4 (elevated),
the difference in gain was at most a few db.

I operated the 2017 Stew contest from a northern beach of St George Island,
FL. The antenna was inv L about 55 ft vertical and 90 ft horizontal,. with
one 70ft radial elevated 5 ft.

The performance was astounding. EU was heard one hr before the sunset, in
bright sun..During the contest, EU were only slightly weaker than the US. A
special point was easily working a DL with 100W while a well known
contester using high power 100 miles inland could not work it.

So it seemed that the salt-water enhancement was like 15 db, not a few. I
wonder whether simulations are inaccurate with respect to radials/soil
type or is salt water special?

Re: Topband: OT - US Hams, WWV closure

[K9FD]

NIST budget is 750 million,   the budget committee is increasing the 
years budget to

them by 125 million,    100 anniversary celebration coming,
I dont think there is any danger of them going off the air for some time.


Some folks have commented on WWV's
minuscule operating expense when compared to the total federal budget, but
the problem with that thinking is we have thousands of federal programs and
departmental budgets that also contribute just a tiny fraction to federal
expense.  Collectively, it adds up to a much larger figure.  No matter what
goes away, the impact is felt by someone.

I've heard Fed. Gov't burns through $6 Mil. every minute (maybe it's
every second).  In the time it took to read this far, Bam another $6
million.  Sure there are lots of dinky things the U.S. blows money on
and if no one defends them then they go away if they're up for a
defund.  NIST is sending up a trial balloon maybe?   Well, if there
are enough tech. trogs using WWV and we make enough noise, maybe this
dinky little program will get saved.  Let them cut funding for some
stupid study on why moss only grows in shade.   Bam, there went
another $6 million.  Don't know about all of you but I have a hell of
a lot of things to do besides mess around trying to set up my own
rubidium  doohicky because WWV went away.  Bam there went another $6
million.

Re: Topband: 3B7A

[K9FD]

He was good copy out here in KH6 land, happened to tune the band at 1600Z
and he was 559,  later he came up to 579,   heard him an hour past 
sunrise and

still going.
JT1CS was also on the band about 1600Z.   too late of course for most 
USA but

they may be on earlier than that,

Good hunting,
73 Merv K9FD/KH6

Elusive again tonight but a better signal
than yesterday. Only heard him well at the
beginning of GL and he dropped off 30 min
later. Could hear EU calling him clearly
before GL so the band was in decent shape
still. Going to be tough for me to hear
him at this QTH but that's the game.

GL to all,

73,
