Topband: condx 160m last days

[Andree DL8LAS via Topband]

 Hey from DL,


i tested the last weeks my new beverages,
and I can say now, band is mostly open USA to EU
the last weeks  at 4.00 UTC and 22.30 UTC.

I heard many US stations and worked 

KC1XX, NP4Z, 8P9AE, K0ZK,W1UE, NY2PO...
So hope to work you the next weeks on topband

Hi Dave

We just can wait for it. Patience., good conditions is coming to stay for 
several years.

Topbanders. . .

Although my geographic perspective is much different than Steve's, I concur 
that conditions so far this season have been very poor with the exception of an 
occasional bright spot. . . many nights/mornings being remarkably poor. 
Far inland here in the Midwest (Iowa) I go night after night listening to 
European stations (and mornings looking toward VK, JA, etc.) that have 
typically in years past been Q5 with S5/S6 signals. . . but the signals are now 
weak, just above the noise floor, and often uncopyable.  Probably the bright 
spot this season has been with VK.  While I have only been QRV on TB since 1987 
(many of you have me beat by two decades or more), I have gone through several 
sunspot cycles.  The old adage that low sunspot numbers bring good conditions 
to 160m does not necessarily seem to hold true. 
Obviously, there are other significant factors at work (or combination of 
factors).  I was holding my breath, hoping that the bottom of the current cycle 
would bring great conditions but it simply has not happened. . .at least here.  
A classic example is a stalwart topbander in Germany.  In years past (several 
years ago actually) he would have S5-S8 signals, night after night, week after 
week, season after season.  Many nights this season he is barely copyable and 
often not even copyable.  Upon inquiring he informed me earlier in the fall he 
had not made any changes in his nice station.  My last good skewed path opening 
(w/9M2 my morning hours) was September, 2010. 
I have seen virtually no signs of skewed path since.  While all this is a bit 
discouraging we, of course, plod on in anticipation of better conditions 
to come. . .which will happen. 73. . .Dave, W0FLS

Subject: Topband: Poor conditions in 2018 so far for working VK6 to NA long path

G'day

With the exception of last Sunday I've been on 160m for east coast NA sunset 
from 7/11/18 until 12/11/18 to try to give out some ‘long path’ contacts with 
USA/VE.

Although there has been some spotlight propagation into Europe (today was 
Southern Europe/North Africa and S01WS for a new country) the LP into North 
America has seemed to be non-existent so far.

2017 and 2016 were definitely better, with my recollection of LP openings 
present on several mornings during this period.

My reference point is if I can hear or work Jeff VY2ZM, then I know there is a 
chance of working into NA further south.  Every morning I regularly check 
Jeff's transmitting frequency - and during the aforementioned period I haven't 
heard Jeff once!

Since Jeff started his station on PEI, we have worked on 160m many times - and 
on SSB at least once - and usually I can hear him virtually daily at this time 
of the year.  This year is definitely the worse I can recall since I first came 
on 160m from VK6 back in 1995.

I guess the take-away message is 2018 is a very bad year but east coastal NA 
stations don't give up hope that a LP QSO is possible (but perhaps not this 
season).

Re: Topband: 160m Condx

[Lee STRAHAN]

Just as a reminder to all that these BCI problems can also occur at 2nd and 3rd 
order IMD mixing.
Example 3rd order,  one station on 1220 where 2X equals 2440 and a second 
station at 620 subtracted puts a 3rd order product right on 1820 .
Another example 3rd order, is 2 stations at 600 where 2X equals 1200 added to a 
second station at 610 for a 3rd order product at 1810.
Second order is 1190 +620 is  1810 KHz   or 860 + 970 KHz is 1830 KHz
 These type of IMD products can be as a result from any amplifiers inline with 
the antenna and radio or even the radio itself mixing in nonlinear devices like 
BJT or FET transistors, even passive devices like transformers and crystal 
filters.
   This is directly related to the 3rd and 2nd order IMD specs on any 
particular piece of equipment.
  Sometimes these spurs are not just BC station harmonics.

Concur . if a frequency either ends with a zero, or if you add the digits 
up and get a number divisible by 9, it will likely have a greater change for BC 
interference. 

Example in Tampa (Florida, US) is 1860, which is the 3rd harmonic for WDAE 620, 
which is a 50kW stn.  An example for our UK friends is 1818, which is the 2nd 
harmonic for 909khz (BBC Radio 5)

Know bad frequencies- great resource here: 
http://www.k8nd.com/TopbandBadFreqs.pdf

However…a “best practice” on 160m is NEVER call CQ on an exact frequency.
Why is it ever necessary to call on 1830, 1820, 1822 etc. exactly? Call CQ on 
1820.3, or 1820.4 or 1822.6 or 1827.8.
Perhaps its human nature to want to use a nice “round” number, but this 
accomplishs nothing except increase the chances of being on a harmonic QRG.
Its surprising how many DX-peds will do this too. We don't need a nice 
frequency with no decimal points! You will be found just fine with all the 
skimmers and spotters out there.

Know bad frequencies- great resource here: 
http://www.k8nd.com/TopbandBadFreqs.pdf 


However…a “best practice” on 160m is NEVER call CQ on an exact frequency.
Why is it ever necessary to call on 1830, 1820, 1822 etc. exactly? Call CQ on 
1820.3, or 1820.4 or 1822.6 or 1827.8.
Perhaps its human nature to want to use a nice “round” number, but this 
accomplishs nothing except increase the chances of being on a harmonic QRG.
Its surprising how many DX-peds will do this too.  We don't need a nice 
frequency with no decimal points! You will be found just fine with all the 
skimmers and spotters out there.

Re: Topband: 160m Condx

[Richard (Rick) Karlquist]

A related issue is that frequencies ending in 0 and 5 tend
to attract casual operators who can't hear DX.  Many times
I have heard them start up and call CQ on top of DX.  I
like to choose a frequency ending in 2.5 to avoid the
casual ops.  On the high end of 40, this neatly avoids
BCB stations, and any decent rig can notch out the 2.5
kHz heterodyne.

Re: Topband: 160m Condx

[Paul Kiesel via Topband]

Aren't US and Canadian broadcast stations on frequencies
that are divisible by 10, like 900, 910, 920 kHz? That would
place harmonics on 1800, 1820, 1840, etc. I think I read
somewhere before that European broadcast stations are
separated by 9 kHz. Could be remembering wrong about
that, though.

Topband: roasting earthworms

[N7DF via Topband]

the morning after a wind and lightning storm i found that i had a 20 over nine 
power-line noise problem on 160 meters  on my triband beam it peaked north east 
on 20 meters     i waited a couple of days to do anything about it because i 
knew that our small electric cooperative was overwhelmed with repairs but when 
there was no improvement i took it on myself to try to locate the problem  
tuning my car radio to a blank space between two stations on am i drove north 
on the main road up our canyon   about a mile north the noise became very loud 
on the car radio and as i approached a side road it became overwhelming  as 
soon as i turned on the side road i saw the problem  the lower neutral wire was 
down and lying on the ground between the first two light poles on the spur line 
going down the road   i checked the first pole beyond the break and found that 
i could get a spark off the ground wire on the side of the pole   i called the 
electric cooperative and they sent out a crew and strung a new line between the 
poles   surprisingly none of the four residences on the quarter mile long line 
past the break had reported the downed line and had not experienced an outage 
of electric service  the 7200 volt transformers at each residence had been 
connected to the neutral side of the transmission line through the ground wires 
on the individual poles even though the ground conductivity here in the desert 
is extremely poor  after the new wires were installed the noise from that 
source was significantly reduced

Topband: Low bands DXing group on Telegram

[Ashraf Chaabane]

Hi all,

I’m not sure if there is a low bands chat group on any of the chat apps
(please advise). I herein suggest to have a chat group on Telegram
application.
Anyone with an Android or iOS mobile would have access to the that chat
group.

I know most of the lowbanders want to be old fashioned guys, no doubt
ON4KST is great, but it’s useful to always be able to check conditions
easily from any place you are in using the mobile.

I opened a new channel named: @LowBandsDXing

I will see how many people are interested to join. If you couldn’t find the
group, please email me in private.
