[IRCA] Alberta TPs for 6 November 2018

[Nigel Pimblett]

No sign of any Asians returning here yet after the solar hiccup.   Quite 
a number of weakish DU signals did make it today though.  Australians 
heard on 549, 612, 774, 792, 828, 891, 1548 and good reception of KUAU 
from Hawaii on 1570, which had been missing during the good Asian 
conditions.



73,

[IRCA] November 5th & 6th DX at Cape Lookout State Park

[Guy Atkins]

My initial impression of the band on Monday morning held up through closer
inspection of my FDM-S2 recordings: it was dismal indeed. Although I'll
take coastal DXing any day over inland, the "sea gain" effect still bows
down to the propagation gods.

Tuesday morning showed promise from around 1400 onward, but it was mostly
just whispers of NHK audio from the strongest tier 1 stations. I did notice
a very weak CRI trumpet fanfare on 1017 kHz at 1500 beneath a presumed.
slightly stronger JOLB Fukuoka, but that was the only non-Japanese TP I
heard.

The star of the morning--to save it from the trash heap--was JOAK Tokyo on
594. It persisted at a strong level, with J-pop such as this crooner from
Yukari Onishi (thanks for the artist ID, Shazam app!):
https://app.box.com/s/krho5he9jq3l9oyelhz2vsw1xvx5zwj5

 It's tough to fault the lackluster DX when you can take a few steps
outside and enjoy the sights and sounds of another kind of wave:
https://www.youtube.com/watch?v=cWxkNnoFo9I

During the day I experimented with a new prototype Wellbrook module that
works with a connection to the core of a Ferrite Sleeve Loop antenna. It
performed better than previous broadband FSL efforts, but still fell short
of an inductively coupled, "one frequency at a time" FSL. The champion of
broadband compact antennas remains the ALA1530LNP Imperium, in my opinion.
It packs a lot of performance in a 1-meter diameter package. Like the FSL,
the loop fits into locations where other antennas simply cannot (such as my
cabin at Cape Lookout that's surrounded by dense brush and foliage).

Re: [IRCA] BOG question

I find it interesting that a very similar BOG / receiving antenna discussion is 
also going on with the Topband reflector.

There's a fair amount of belief that terminated loops in a phased array or just 
a single double loop style (DHDL, DKAZ, Bowtie, Waller Flag) can deliver as 
good or better RDF (directivity figure of merit) as a single BOG / Beverage on 
an equivalent size piece of land.  Staggered phased Beverages are likely 
another matter.

Neil Kazaross in IL makes use of both terminated loops and BOG's and I believe 
Tim Tromp in MI does too.  Perhaps Mark Durenberger and Walter Salmaniw as well.

Comments from those guys and others could be valuable.

I believe both types of antennas are presently in use by the PEI DXpedition..

[IRCA] 6 Nov Victoria version.

[Nick Hall-Patch]

Mostly quiet on the western front this morning, with a brief tick upwards just 
before 1450UT.   Although signal levels were still suppressed, a couple of 
Chinese found their way through, but DUs hardly made an appearance at all.



pretty darn good audio (all of it understandable by a native speaker, at least 
briefly):


594 came close




Reasonable audio at  times during the period (much of it understandable by a 
native speaker, though often battling w/splash or noise):

567 JOIK  man in Japanese //594 1427UT

594 JOAK two men in Japanese 1434UT



not so reasonable audio, occasional words or phrases in splash or noise could 
be understood by a native speaker: 


747 JOIB man in Japanese 1426UT

774 JOUB English lessons 1434UT

828 JOBB woman in Japanese 1448UT

945 CNR1 likely man in Chinese 1449UT; two sets of Chinese pips at 1500UT, one 
7 seconds delayed from the other

1566 HLAZ likely, man in Chinese 1449UT


Burbles in the splatter and noise (if lucky, language might be guessed at by 
cadence of talk, or parallel established by changes in talk or music) 

612 man talking 1440UT, DU English intonation

621 woman talking, Chinese intonation 1449UT

972 man and woman in Korean? 1450UT


Strongish het, no or "near imaginary" audio (either undermodulated or ravaged 
by splatter)

603 711 837 873 918 1188 1323 1377  1503 1575 1593  seemed to be Asian; 
756 seemed  to be DU

Re: [IRCA] BOG question

[Russ Edmunds]

IN its basic sense, the name "BOG" came from "Beveridge -on-Ground", and indeed 
one of adequate length should behave similarly.


I don't know either of the two people you mentioned, but any of my interactions 
with 160 meter guys  have resulted in some very strange ideas

Thanks Chuck; I knew I could bring you out of the woodwork.

There's been a fair bit of hand-waving on the topband list about the
BOG over the years, partly because anecdotally, either they "don't
work", or that they have very good F/B.  K2AV has done a lot of
measurements, and seems to conclude that a proper BOG (not a wire
near dry ground) is actually a resonant
antenna,   http://www.iv3prk.it/bog-modeling.htm puts forth the same
idea.  This is for the limited frequency range of 160m; the entire MW
band might prove interesting depending on length, ground conductivity etc.

I'd assume that a BOG at Grayland especially in the summer would act
more like a Beverage.   Did you ever compare a "BOG" with a raised wire there?

Re: [IRCA] BOG question

[Russ Edmunds]

My experience is exclusively on a sand beach. We found early on that a normal 
ground wouldn't work. We ultimately ended up with a fan of 4 radials through, 
IIRC about 220 ohms.  We haven't been able to use BOG's since Hurricane Sandy 
several years back. We had one running up the coast ( 37 degrees) and the other 
down coast ( 217 ) and they were indeed directional at 800-1000 feet.

We even had success at 500' but the pattern was broader.

Re: [IRCA] BOG question

[Chuck Hutton]

I don't see the self-terminating thing.


It seems to me (unscientifically) that the losses are maybe 5 to 7 dB. That's a 
far cry from the 30 or more dB loss in a properly terminated system.

Have you had success terminating a BOG Russ?   (supposedly it is ~200
ohms, rather than the raised Beverage's ~450 ohms).

I think some have found that it is self terminating, to a degree, as
there is quite a bit of loss on reflected signals.

[IRCA] Hawaii DXpedition 702 kHz Mystery Solved

[Gary DeBock]

Thanks to two awesome Finnish DXers (Mika and Mauno) for taking the time to 
assess my 702 kHz UnID language recording from 1604 UTC this morning, and give 
their expert opinions that this is Arabic from the BBC transmitter in Oman 
(8,615 miles/ 13,849 km). This is far and away the best DX catch ever made with 
the hand-size 5 inch "Frequent Flyer" FSL antenna, which has already greatly 
exceeded expectations here in Poipu, Hawaii. BBC's Arabic signal was actually 
pretty strong this morning, unlike the threshold level of the past few days

Re: [IRCA] 621-Pyongyang BS/ VoK-- Audio Situation Becoming Critical

[Nick Hall-Patch]

Didn't the discussion also cover whether the hum increases in 
intensity as  Chongjin fades down, and decreases as it dominates the 
frequency?   I believe that increasing hum with increasing Chongjin 
signal strength would indicate that the hum is part of Chongjin's 
signal, rather than due to the heterodyne with other signal(s).

A few months back there was a discussion on the list about the 
transmitted audio from the 621-Pyongyang BS/ Voice of Korea station 
in Chongjin, N. Korea-- specifically, whether there was audio hum 
on the frequency from a bad transmitter, or whether the bad audio 
was caused by a drifting frequency.


  Yesterday morning a recording was made of 621-Pyongyang BS 
mixing with 621-China (Heilongjiang) at the 1500 TOH, with the two 
sets of pips loudly overlapping at the 39 second 
point  https://dreamcrafts.box.com/s/612kbk25hqqlxh1r4qfzaxzeuuwktbeo


The throbbing hum from Chongjin's transmitter is pretty obvious, 
distorting not only the Pyongyang BS audio but also covering 
Heilongjiang's clean signal. The overlapping time pips from the two 
are in the same bizarre league as the "Cuckoo Clock" overlapping 
pips from 918-Shandong and RNZ at 1700 UTC in the Cook Islands.

Re: [IRCA] BOG question

[Russ Edmunds]

It isn't a dumb question because the answer is yes and no. If you terminate a 
BOG at one end, that should more focus the reception pattern in favor of the 
terminated end. If you're looking for stations from the N, then terminate at 
the N end. In the event that the desired result is an antenna which receives 
both N and S but nulls E and W, then you lay it out N-S and do not terminate it.

Thanks Colin,

This morning's session was an absolute blast here-- both 675 and 711-VOV with 
S9 peaks, 918-RNK putting on a concert of Cambodian music at a strong level, my 
702 unknown language UnID suddenly pounding in at S9, etc. And as a bonus, we 
get to miss the political nastiness in the mainland! :-)
Ruth and I had a nice phone conversation with Toni last night-- Ruth and Toni

Re: [IRCA] BOG question

[Russ Edmunds]

160 meters, being above the AM/MW band could be effective at somewhat
shorter distances than for AM/MW, but 150-200' isn't really a BOG (
Beveridge on Ground ) it's a longwire. A BOG needs to be upwards of 500' I
would think. I've used BOG's on MW/AM ranging anywhere from 500' to 1200'.
The main difference as the length goes up is that the antenna's pattern
becomes tighter.
