Re: Topband: 9Y4/OK2ZI 60m? +1

[Petr Ourednik]

Hi Steve and Karel,

On the 9Y4 (ITU Reg.2) the band 5250 – 5450 kHz is allocated on a secondary 
basis to the Amateur service. Maximum output power is 1.5 kW... 

The best way for US is to use ch5 / 5405kHz.
In case of split operation it is commonly used ch4 / 5373 for TX and lsn up on 
ch5 / 5405kHz.
In case of QRM on these channels it can be used also ch1 / 5332kHz... any kind 
of split hopping
in between these channels.
All CW.

I can recommend to use also split arrangement for EU (many EUs wants to work 
their new one 9Y4):
Use 5352kHz for TX and lsn up1 or up2 for EU / WRC-15 allocation.
All CW.

Many thanks for activating 9Y4 on 60m band!

Re: Topband: Satisfactory fiberglass pole for K9AY loop

[Petr Ourednik]

Hi Pete,

i am using for years the Extra Heavy duty 10m fiberglass pole from DX-Wire (the 
only GRP Mast "EXTRA" 
heavy duty "strongest" mast with 18mm tip section!) and I can recommend it as 
the strongest pole
I ever used. It has nothing to do with tiny poles available on the market...

Re: Topband: Topband Phenomenon

[Petr Ourednik]

Hi all,

I have the same experiences from this weekend during the FOC Marathon on
Topband. I heard the same in case of G's and other coastal stations > it did
not happened with sigs from inland stations... the difference was few S units.

Even more I noticed another "SDE" phenomenon this weekend which sounds strange 
to me.
I made short vid here: https://youtu.be/cV3rzlsZbA4

QSK has been useless at that time, it appeared only on TB (nothing on 80m).
North signals came thru fluttered. US sigs raised up at that time for several S 
units.
All happened with 300m long Beverages to NA and SA ...no difference.

Anybody knows what happened to me that morning? It disappeared in 1.5hr...

Re: Topband: Rather use N-type (was Re: The answer to PL-259 soldering/reliability problems)

[Petr Ourednik]

Hi all,

I can confirm Martin's and Greg's experiences. It is strongly recommended to 
avoid 
using the PLs at all. I did the same changes and since that no problems at all.

Of course any adapters are avoided too. All cables must be properly assembled 
with proper
and high quality N-connectors. Never use/buy the connectors without assembly 
instructions 
including the cutting lengths layout.

The only issue to think about it carefully is the power rating of N-connectors 
(even PTFE).
These connectors are not designed and dedicated for high power and as the inner 
pin is 
a bit tiny I do not recommending to use them over "legal limit"...

I tested the PTFE version of N-connectors at 4kW in the lab and there was no 
problem but
it was in comfortable conditions... low humidity, well mounted, no soft iron 
soldering etc.
The conditions outside the shack can be a different situation...

In general - using the N-connectors with high quality cables properly mounted 
up to "KPA500" 
is highly recommended. The higher power level is deserving the 7/16 DIN usage 
or similar.

(all is talking about "professional" approach to our ham radio hobby)

Hope it helps,
73 - Petr, OK1RP

Re: Topband: VE1ZZ has passed on - Very Very Sad news! (Long)

[Petr Ourednik]

Very sad, 

Jack was my first VE on TB when I got my first novice lis with call
OL1BVR. I was totaly amazed that morning and I was not able to focuse
for anything in school all that day...
I runned 10W only into sloped 41m wire in the city and Jack was the only
guy who found me on the band.
We exchanged dozen of letters and Jack explained me several basic things
about Top band operation. Real gentleman.
I will miss him...

RIP Jack,

Re: Topband: No 160m Sunrise Peak

[Petr Ourednik]

Hi Roger,

as Nick, VE7DXR said already on this reflector I have to confirm that the 
expected "peak" should be more or less the significant decreasing of the noise 
in fact and due to that effect the rapid S/N improvement.

I reviewed my very old logs from 80's (when I was active on TB as OL1BVR almost 
daily) and I found several notices in my log around the SR about dramatic 
decreasing the noise during the grey line phenomenon on TB which is raised up 
back with the coming full daylight.  

On the other hand Dave, W0FLS and others referring to an increase in actual 
signal levels (with corresponding increase in S/N).

So it looks like both of these effects are playing the role in the game...
Is there anybody who made an observation using some SDR + PC s/w spectrum 
measurement during the SR/SS please?   

Best regards,
73 - Petr, OK1RP

Re: Topband: Band Open - But No Sunrise Peak

[Petr Ourednik]

Hi Tom and Roger,

I decided to add my 2c as I noticed the same behavior with no GL peak for last 
weeks
over here...
I remember the great peaks during the Grey line phenomenon condx window 
years ago but not now. I tried to observing the condx during the GL window for 
last 
few weeks on TB (thanks to Xmas time and my illness on ATB) with the similar 
results
as Roger reported. 
Also I tried to switch in between several RX antennas like W2PM MiniDiamond 
loop, 
K9FD loop, low dipole as same as my TX antenna (loaded half sloper) and there 
was no 
difference regarding the peak at the GL time...

Re: Topband: 160m beacons list update

[Petr Ourednik]

Hi JC,

thanks. The YR2TOP beacon responsible is YO2LC se we should talk about
it to him.
If I understood well what he is doing to preserve the band a bit is that
his 100W
beacon is turned off during the big contests.

Yes, the frequency of the beacon as same as 100W out is an unhappy
choice I guess...

Re: Topband: New Noise - 160 Meters

[Petr Ourednik]

Hello,

not only the "defective" LED lamps makes the noise.

I found several LED strips (used commonly in kitchen)
and LED bulbs coming from China generates strange noise 
on HF bands. I noticed it when the noise raised up from S3 to S7
on 160m while I was on key. So I immediately went to investigate
what was changed at our home and I discovered that XYL switched
ON the LED strip installed in kitchen cabinets.

The same noise source was the LED bulb in the small bed lamp in the
bedroom. After I replaced all of these Chinese crappies with standard
lamps
the noise gone. (LED strip in kitchen cabinets must be OFF when I am on
key, hi)

Hope it helps,

Re: Topband: 470 non carbon resistor

[Petr Ourednik]

Hi Rag,

the important is to look for carbon composition / ceramic composition
resistors
at 2W power rating at least. The Ohmite has their OY series / 2W for
example.

Mouser:
588-OY-470-E 
http://eu.mouser.com/Search/ProductDetail.aspx?qs=K%2fk%252b2unYRtW4en7Bt3IFdQ%3d%3d

Farnell / Newark:
64K5431 
http://www.newark.com/ohmite/oy471ke/resistor-ceramic-470-ohm-2w-10/dp/64K5431

The resistors datasheet:

Re: Topband: CQ WW 160 from VK Land.

[Petr Ourednik]

Hello Ron,

many thanks for informations. It is explaining a lot... :)
We tried to catch VKs but no way this weekend.

Short report from our OK5T event this week is here:
http://160mband.blogspot.ch/2016/02/cq-160m-dx-cw-contest-2016-at-ok5t.html

I am sending my big apologize if we accidentally QRMed someone during
the contest.
I really adhere to good manners and gentleman's operation. We always
tried to stay at least 
300Hz far from another station when looked for QRG for RUN but sometime
it was hard job 
on so crowded band.

I hope to hear and work you again in the contests as OK5T or as my own
call OK1RP.

Re: Topband: safely sharing an RX antenna

Hi

it sounds like SO2R on the same band... Its interresting for me too. I
am using one solution in CQ160m in order to use 2nd radio for S but
its disconnected from antenna and grounded as same as 1st radio in RUN

Hi,

there is an improved list of the TOP band beacons on new 160m band blog
(bothering advertisement free)

http://160mband.blogspot.com/2015/07/160m-band-beacons-list.html

As You can see it is still trial and it's not final version and many
of the beacons listed over here was reported 
years ago... maybe an operation has been cancelled or so. I will be
appreciated to get any report or info about 
beacons from 160m band in Your location to put it into the list.

Re: Topband: ARRL 160m contest and DX Window?

[Petr Ourednik]

Hi Peter

I don ´t think so.  :)
I have just 2x BOGs, 1x Hi-Z vertical and MiniDiamond W2PM loop all
connected to
wireless antenna switch. If You will add the 
time for tunning around frequency using RIT + playing with four rx
antennas and tx antenna 
then You have about 5sec...
Well of course sometime its all much shorter but 
I wanted to note that listenning just 2-3sec only 
is really short and it´s possible to missing weak sigs very easily...

Thank You Peter,

Re: Topband: ARRL 160m contest and DX Window?

[Petr Ourednik]

Hi all,

the split JA operation schema for decades ago was:
JA TX  1907.5 - 1912.5kHz and listen for rest or worls in between 1820
- 1825kHz.
This JA window 1907.5 - 1912.5kHz has been not used in contests from
1999 by JARL 
because the band was too narrow. The SSB was not permitted. 
I worked several JA topbanders over there split down to 1820 - 1825kHz.

According to the Ministry's announcement, effective April 1st 2000,
additional 15kHz, i.e. from 1810 kHz to 1825 kHz, has been allocated for
amateur radio use. The announcement was available in the
Japanese language at
http://www.mpt.go.jp/top/public-comment/public-comment000207.html
but it does not work I guess.

You might be interested in JA band plans which is available here.
http://www.jarl.or.jp/English/6_Band_Plan/JapaneseAmateurBandplans20090330.pdf
Some additional notes to the figure:
NB Phone = SSB, AM
NB Image = SSTV
NB Data = RTTY, PSK31, JT modes etc
(but no RTTY on 2200 and 160m)
WB Phone = FM
WB Data = Packet
(tnx to Rin, JG1VGX)

Regarding the DX window down on TB I am trying simply not calling CQ in
between 1825 - 1835kHz
from EU. In fact my CQ is even not so effective from my fixed QTH as my
receiving performance is not 
the best so I would not like to bother on the band when I am not able to
hear weak sigs coming back.
In general calling CQ with just few sec of hearing to repeat CQ again is
terrible technique which is not
applicable on TB I guess. When I am calling CQ I am trying to listenning
with switching between all of
my RX antennas combination to ensure that nobody is calling me... so in
my case I need to listenning
between each CQ at least 30-45sec I guess.

Also there are bad spots (forbidden QRG) on TB which should be avoided
for CQ.
1820 is often jammed by radar from China in JA
1818 strong QRM from local GPS correction on 1818 in ZL

To keep the Gentlemen band (better to say  give it back to the old ages
Gentlemen shape) we should
strictly observing basic gentlemen agreement...

My 2c...

 Subject: Topband: ARRL 160m contest and DX Window?
 
 The ARRL 160 meter contest is this weekend. I know there has been a lot
 of
 controversy in the past about the 1830 to 1835 segment (the so-called DX
 Window).
 
 I understand that if I am in the USA, the right thing to do is to NOT
 park
 in that window and call CQ (but I can answer a CQ from a DX station on
 another continent or island). The rule at http://www.arrl.org/160-meter
 simply states *6.1. *The segment 1.830 to 1.835 should be used for
 intercontinental QSOs only.
 
 Maybe some of the more experienced Topbands could clarify this.

Re: Topband: FW: Front End Saver for Top Band

[Petr Ourednik]

Rodger,

I built several of them for my station as same as for our local contest
club station and all works like champ. (Martin's version)

State nr. 1
QSK T/R is floating
Re1 - closed
Re2 - open
Re3 - open
In this case ANT port is connected to RX input port and AMP port is
floating. 

State T/R is grounded
Re1 - open
Re2 - closed
Re3 - closed
In this case ANT port is floating, RX input port is grounded and AMP
port is grounded too. 

Hope it helps.

 Has anyone built the front end saver by KD9SV or the OK1RR version which
 uses 12 volt reed relays.
  
 I am attempting to build the 12v version on veroboard and have the
 following query, when the unit is supplied with 12v relays 1  2 are
 energised, when the PTT is operated relays 2  3 are energised basically
 relay 2 remains energised at all times, is this the correct sequence of
 operation?
  
 thanks Rodger/GM3JOB

 A friend of mine is building me a switching arrangement with a reed relay

 As an added measure of protection for the KD9SV low noise pre-amp I use
 with my 160/80 delta loop antenna, he believes clamping the RX antenna
 port or shunting to ground during TX sounds like a nice thing.  But, he's
 seen arguments that clamping receiver input with diodes degrades the
 receiver performance. He find this believable, but I don't know how true
 it is, e.g., he knows KD1JV claims his RX performance is achieved by
 using 2N7000 FETs to do T/X switching.
 He has a bunch of 2N7000 and will probably use one to turn on the relay. 
 He can turn on another one along with the relay driver that will shunt
 the RX antenna port to ground but he wonders if that would degrade
 receiver performance.
 Thoughts?  72/72, Jim Rodenkirch K9JWV

Re: Topband: K3 some interesting noise lessons in the ARRL 160.

Hello Guy,

Thank You for an interesting analyse. 
Which s/w and f/w do You have on K3 loaded please?

 This may be specific to a K3 and no joy for other rigs. But there might
 be
 parallels elsewhere.  Definitely YMMV.
 
 Usually in a 160 contest I try and get a run frequency down around
 1815-20.
 For some reason in my locality that range is, and for a long time has
 been,
 a general garbage minimum in the noise floor around here, sometimes 2-3
 dB
 better, so there is no incentive to CQ elsewhere. I have not had a
 problem
 establishing down around 1815-20, even when running 100 watts.
 
 But this year, off and on since late summer, and of course without any
 rhyme or reason or published schedule, I have had a really bad
 intermittent
 power line style buzz that was S7 to ten over S9, depending on only
 heaven
 knows what. I have not had any luck localizing it, largely because of
 it's
 variable and erratic nature. A lot of the time it has irregularly
 separated
 fast bursts, almost like it's trying to send Morse with its buzz.
 
 On the first night of the ARRL 160 contest, buzz was entirely absent. And
 I
 actually had the ARRL 160 weekend clear of family conflict for the first
 time in recent memory. Oh Joy! By the end of the first night I already
 had
 a personal best for the contest. The second night the noise struck half
 way
 through with a solid buzz. Ten over S9 in my usual hangout 1815-20-ish. A
 little less noise up higher but still covering all but the louder
 signals.
 No real help using my newly repaired and pattern-verified NE RX antenna.
 Loud there, too. Earlier work had ruled out a source in my or neighbor's
 houses. No quickie fixies.
 
 I was unable to hear anything except the louder signals, which I had
 pretty
 well worked out the previous day.  Forget operating. So I decided to
 experiment with the noise mitigation methods/settings on the K3.
 
 Usually in these buzz circumstances, you can't find a persistent weak
 signal on 160 far enough into the noise to let you experiment with noise
 mitigation settings based on signal to noise. You wind up using the
 reduced
 noise level as the only clue for settings.
 
 Reduced noise level method is fine if you are working strong signals and
 you just don't want to hear the noise. But to pull out weak signals what
 you really need is to restore signal to noise separation all the way down
 to the weak signals. It turns out best signal-to-noise and best
 level-of-noise do not always generate the same weak signal readability.
 Some methods/settings reduce noise well but also trash the weak signals
 in
 the process.
 
 But being the contest, 160 was *loaded* with weak signals to test with.
 So
 I spent a few hours experimenting with K3 settings on weak signals,
 optimizing for S/N. Came up with NB only (no NR) DSP T1-7 + IF NAR4 using
 250 8 pole filter, which clearly gave the best separation between weak
 signal and noise, without the usual weak signal obliteration from
 traditional noise blanking in a contest.
 
 Usually the buzz gating the NB will add a 180 Hz raspy modulation (center
 carrier and +180, -180), an irritating buzzy noise, and can mush the
 wanted
 signal.  Narrowing the CW width to 250 or 200 Hz (+/- 100 Hz) cleans off
 both the modulation (3 x 60 Hz), and signal-covering hashy fuzz caused
 by
 the irregular shape of the buzz waveform.
 
 After the determination of those settings, I scanned the band with those
 settings in NB. I discovered a narrow null in the noise or sweet spot
 between 1831 and 1833, sounding almost normal, with clear rendition of
 weak
 signals, which was up to 2 s-units better than the NB improvement in the
 least effective spots, which included my normal hangout of 1815-20. 
 Don't
 ask me how that works, because I haven't a clue.
 
 1831.5 was unoccupied, as was 1832.5 in a later stretch, where operating
 with the blanking on, it was as if the noise was not there at all. (See
 an
 earlier post about my unfortunate adventure with the DX window rule.)
 
 That narrow sweet spot in the blanked noise was still there Tuesday, at
 1830-1832. With the noise back solid, and using the NB settings above,
 Tuesday night I was hearing LZ2DF on 1832 clearly, at what I would call
 559
 or 549. He was not hearing me running 1.5 kW, so this was clearly a
 normal
 state of affairs, controlling noise was on his end, not mine, even though
 the buzz was full on.
 
 Wednesday the buzz was there with separated bursts, but not quite so
 loud,
 and the aforementioned NB settings killed it at least semi-decently
 across
 the band. Go figure. I was able to clearly pull out way-down birdies and
 such, simply not there without the NB.
 
 Thursday the noise-blanking sweet spot was at 1.838, and a little broader
 than during the contest. The RX antenna clearly hears a weak birdie at
 1.838 much stronger than on the TX. Yes, Virginia, the RX antenna has

Re: Topband: RIG PROTECTION FROM BEVERAGES

[Petr Ourednik]

Wayne,

I am using the home made KD9SV front-end saver for long time on receiver
input and
I have never any troubles with blowing the receiver input port. Fast
high quality relays 
is th key, just to think about the protecting diodes of the relays which
are commonly 
used in these kind of circuits. I am not using them in order to avoid
IMD issues.

Regarding the lightning / storm protection I am always disconnecting
coax feedlines from
radios and grounding them OUTSIDE the house. It is uncomfortable a bit
but the most secure
for equipment I think.

Hope it helps,

 Thanks to several of you who responded, I now know the larger concern
 should be the Beverage feeding my transmitted signal back into the
 receiver. This is probably of particular concern since I always use my
 linear at about 1500W when transmitting.
 
 
 However, no one proposed a solution.
 
 
 I have been looking on the Internet, and one possible solution is Array
 Solutions Model AS-RXFEP, RF Front End Protector.  The advertising claims
 to protect in the feedback situation as well as in a lightning situation.
 The insertion loss is claimed to be only 0.3dB.  For only $55 this seems
 like a good investment.  Does anyone have experience with this unit or
 would you please suggest an alternative?
 
 
 Thanks again for your help.

 Ive said several times that my 500' BOG's dont need a preamp. The signal
 level may be 5-6dB lower than the elevated ones in the same direction but
 thats more likely due to signal angle.
 
 One or two on here keep claiming 500' wont work and I say it all depends

 For best performance you need to know your RF ground resistance and wind

  How does the signal level from a BOG compare to the signal level from an
  elevated Beverage? I'm sure the output from a BOG is less. But how much
  less? Enough to require a remote preamp? I've always wondered.
 
  I --and many others-- have found a remote preamp on an *elevated* Beverage
  to be totally unnecessary, even with the lossy matching transformers that
  I

Hi,

I do not know what our antenna's gurus will say about that but I can 
recommend DO NOT spend so much money for that magic receiving antenna.
Try all the other free first  like BOG, loops etc. You will spend 
just few USD and You will get more experiences what works for You and
what
does not work in Your place. Finally if You are looking for some
commercial
then have a look for 3el. Hi-Z array. Even You can do it home made and
works
well  just put it as far as possible each of the verticals apart from
TX ant.
