Topband: The Stew Perry Low Band Jack/solar conditions on 160m

2022-10-25 Thread Steve Ireland
G’day

It was great fun to do the Low Band Jack over the weekend.  Conditions were 
very spotty/spotlighty, typical from here at this point in the solar cycle.

Only 15 QSOs in the log, with two Aussies (VK6GX and VK3IO, the latter of who 
would have been more active but for high QRN), eight Europeans and five USA. 

Several W5 stations were heard at S5/6 but neither Phil or I could raise them, 
suggesting either one-way prop or receive antennas pointing away from us. 

As Phil VK6GX warned me before the LBJ, there was nothing heard west of the 
Rockies, with the skip going out as far as K1LT in eastern OH and K0DI in FL. 
This type of prop has been present recently, during Phil’s regular visits to 
160m.

My 160m signal/reception isn’t as good as it used to be, owing to swapping the 
single-band inverted vee dipole at 90 feet into a inverted-U doublet at 50 
feet, which also functions as a Half Square on 80m and is a super DX antenna 
for contesting. 

I was very interested to read Steve VE6WZ’s reports on how DX contacts over the 
North Pole have diminished for him, as solar activity has increased.

In VK6, most of our DX comes in from either the east/north east (USA/Caribbean) 
and west/north west (Europe/Africa).  Polar propagation (N/S) is there for us 
at sunspot minimums but doesn’t result in much DX.

Ironically for us here, often the rarest DX is worked relatively close to 
sunspot maximums, owing to being east-west in direction, where prop is 
generally encouraged by solar activity. Over the last 30 years, this has for 
me, for example, included 6Y5, ZF2, VP5, V3, CN, 3V8, 5A and SU. 

I was taught about this propagation ‘anomaly’ many years ago by Mike VK6HD (SK) 
and it seemed weird, until I looked at an azimuthal map of where the true 
directions of the various population centres were located from my relatively 
remote location.  It is all about geography and geometry.  

Topband: Stew/Low Band Jack observations from down under

2022-10-25 Thread Phil Hartwell via Topband
Hi Topbanders, I hope you enjoyed the Stew/LBJ contest as much as I did, 
despite less than stellar conditions and thanks to Tree and the Boring 
guys for organising the splendid event.


Some observations on propagation during the Stew/LBJ from down under

At the start of the contest I worked LY7M and LY2XW, both very weak with 
bad auroral flutter and QRN, making copy very difficult, nothing else 
doing, so a bit discouraged I took a 2 hours sleep break. On resumption 
at 0300 local, the auroral effects had dissipated and signals had 
improved, so I managed to log a few EU's, which were limited to eastern 
and northern countries, none further west or south than DL, except for 
MM0ZBH, 10 minutes after my SR, which was at 2127z.
During the afternoon thunderstorms developed southeast of Perth, the 
first for several months, which didn't bode well for the evening 
session. After SS the local QRN combined with the continuing storms that 
continue to flood eastern VK, to make copy difficult, but I managed to 
work 8 east coast W's from MA down to FL plus MI, all were around S3/4. 
As the SR progressed across the states I heard almost nothing until W5 
appeared around their SR, with half a dozen good signals around S5/6, 
but try as I may, none answered my calls. Then nothing until I heard 
AA6AA, who was peaking S7 at his SR and made it into my log. The only 
other west coast station I heard was a very steady S6, but could not 
hear my dozens of calls.
I heard no VE's, only 2 JA's and worked one. There seemed to be very 
little activity from eastern VK, probably due to the severe QRN or being 
submerged in flood water. The only other VK's I know were active were 
Ron, VK3IO and Steve, VK6VZ. No ZL's heard either.
Now can anyone answer me this? Why was it possible for me to work east 
coast W's who were all weaker than the W5's who couldn't hear me? Was it 
due to local QRN/QRM? Stronger stateside callers drowning me out? Or 
could it be that the east coast stations I worked may have had 
directional RX antennas looking west as their SR approached, looking to 
maximise their stateside contacts, but also favouring my general 
direction and were the W5's looking to the north and east for the same 
purpose, but in the process looking away from me? Was the strong west 
coast station, who did not hear my many calls, looking east? I'm not 
complaining, there would be little profit in listening for VK/ZL given 
the very few stations on air, despite the opportunity to gain many 
points per QSO. I'm just trying to understand why I had almost no luck 
trying to work the stronger stations west of the Mississippi. Any 
explanations welcome.


Anyway, I hope to participate in the Big Stew, southern summertime QRN 
and propagation permitting!


73, Phil VK6GX.

Topband: Stew Perry Contest on East Coast of VK

2022-10-25 Thread vk3io

Hello Top Band Contesters.

Conditions here on East Coast of VK were terrible.

Mega lightning throughout the east coast. Very unseasonable weather for 
this time of year.


Many of the possible Topband contesters (of which there are not many in 
VK) were probably recovering from storm damage and or flooding and were 
either unavailable or had everything disconnected.


For me, it was not so bad at or before my sunrise.

I got on at 1715utc and head nothing, except R3OM, who did not hear me.

I went back to sleep.

Woke up a bit late, just before my sun rise at 1915utc, but only heard 
DR5X, who had a reasonable signal, but who did not hear me, probably 
because he was using a beverage rx antenna not in my direction. DU7ET 
was calling CQ DX almost on the same frequency, so that made it 
difficult. I don't think Bob was in the contest, but we exchanged 
reports and I logged him anyway.


I called LY7M, who had a good signal at 1920utc and we had an easy 
contest exchange.


So I then called CQ Contest on 1824.5 and got a reply from DR5X at 
1930utc who at this time was a stronger signal and then G3OQT, who was 
not so strong but we made a qso at 1933utc.


I think the path to Europe was only open for a short time, as after 
1940utc I did not hear anyone. Typical for this time of October.


During our sunrise time I did not hear any other VK on cw on the band.

During our evening, the QRN on the east coast was terrible and I had 
only one contest exchange with vk6vz.


The VK6's were managing some qso's with USA, but for me it was impossible.

So only 5 qso's for me in total, so I disconnected everything and that 
was it for me, until next time.


Cheers, from Ron. vk3io.
