Re: Topband: Beverages and VK
Merv, I couldn’t agree more. As Merv says“It’s hard as heck to get EU to listen on the skew path”. Last year when the AU was fairly quiet, the direct EU polar path prevailed, but in years past, the skew path was very common. This is also very true for the deep Asia path (HS, 9M2 etc) from VE6 because they are also on a very northerly path. The JAs are not often skewed, usually direct path. All this is also very common on 80m. It is quite normal for the EU signals to be skewed to the south, as Merv says, sometimes with the Yagi pointed to SA. That’s almost a 90 deg path skew! This is NOT subtle, there are time when I have zero copy direct path, but Q5 with the Yagi pointed 90 deg skew. The problem is that many EU ops find that “most of NA” is direct path, but often the west coast and KH6 is coming in over SA, but they don’t move their RX! Wherever you live in the world, when working the lowbands always check for a skewed southerly path when the direct path is close to the pole. Having said that, the arrival angle change near sunrise or sunset is also very common, and can be quite dramatic. 73, de Steve Ve6wz From Babcocks iPhone > On Sep 16, 2020, at 2:19 PM, K9FD wrote: > > 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.

On 80m, my Beverages are a bit better than 4 sq for DX. It depends on the situation. The 4SQ has a wider radiation lobe than the Beverage, and for stations that are not in the precise direction of the Beverage (say a difference of 30 degrees or so) the 4SQ obviously works better. Of course the Beverage has a big advantage in terms of noise. This is what I heard, with a pair of bi-directional Bevs 230 meters long on a very flat, clayey and humid soil, which favors the 4SQ. It would certainly change everything on sand or rock. Paolo I4EWH _ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
Re: Topband: Beverages and VK
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.

Re: Topband: Beverages and VK
At my place the two beverages I am using, 160m to NW, 120m to NE are only good for decent signals. The real weak ones I can only copy with my vertical which is an elevated GP (top loaded tower) fed against a single radial at the 21m level. 73 Peter -Original Message- From: Topband [mailto:topband-bounces+dj7ww=t-online...@contesting.com] On Behalf Of Ignacy Misztal Sent: Mittwoch, 16.

Topband: VK Activity
Greetings, I worked VK3HJ, VK3IO and VK2WF this AM with the first Q 1 minute past SR and the last Q 35 minutes past SR. All three stations were at least S5 and had very readable signals. Contrary with past SR experience, my 400 foot beverage worked the best for RX. It is very exciting to work DX after SR on 160 meters. My final observation was that the band was as quiet as we hear it in January. A fun morning for sure. 73, Bob K3UL _ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector

Re: Topband: Beverages and VK
I am sure you will get lots of input on this - but my experience makes me think that this is due to the angle the signals are coming in from. I often think openings near my sunrise have a higher angle than normal and have found my beverages lose directivity and don't compete well with the TX antenna.

Re: Topband: VK Report
VK2WF was 559 in between QSB into North Carolina this morning. I was unable to hear any JA today, but I will try again later this week. An interesting result, I worked VK6LW/Kevin 1 hour before my sunset on 12 September, via LP, on 80 CW (an hour after his sunrise).N4NX also worked him (about 40 km from my QTH), but no one else called him even though he called CQ until he left his shack for coffee about 20 minutes later. This is an interesting, repeatable occurrence that I shared with ON4UN last year: >>>BEGIN EMAIL TO ON4UN, SENT 09 JULY<<< Hi John I was alerted to an interesting occurrence regarding 80 meter LP prop from US/Canada to VK6. For many years I have observed and read about VA2GU/Roy and his antenna exploits on the low bands - very impressive, as you know. In the winter he easily works VK6 via LP daily. Then I learned that K2RR/Rick, has been working VK6APZ/Peter along with VA2GU and several other Canadian stations, daily via long path IN JULY of this year! >From Rick's QRZ page, he describes his observations of this phenomenon from >his well-equipped station in New Hampshire. It's fascinating! Rick was 80M >DXCC #114; he has been on 80 meters for a long time. So today I decided to listen in on 3793 kHz about 2310 UTC onwards, which is the time of the daily schedule. I was using a HiZ 4 square receive array and an inverted L with 500 watts for transmit. The rig was an unmodified Icom IC-7300. Soil conditions here aren't that great, and I am 200 miles from the coast so I don't get the benefit of saltwater enhancement. Still, VK6APZ went from ESP level at 2310 to 4x4 on peaks (with QSB) by 2330. Although we did not complete the QSO, we came close. Meanwhile, Rick reported 5x9 copy on Peter, strongest signals in months. This is quite remarkable, because my path to the Northeast was strongest (just like K2RR observed) but I was 600 miles SOUTH from K2RR. If this was spotlight prop, the spotlight was in motion and came down the coast! While VA2GU and K2RR have proven that QSO's on low bands in daylight are possible with EU if the equipment and antennas are of the highest order and conditions are just right, this is an entirely different and incredible situation. Long path is unique. Long path on the low bands is quite exceptional (I keep reading your 5th edition book on the subject). Long path with daylight in part of the path on 80 seems almost too good to be true, but I heard it myself. Thanks to Rich/K2RR who let me participate today in the fun, and to Peter/VK6APZ for his patience and persistence. >>>END EMAIL TO ON4UN<<< Mark Lunday, WD4ELG Greensboro, NC FM06be wd4...@arrl.net http://wd4elg.blogspot.com SKCC #16439 FISTS #17972 QRP ARCI #16497 tMke%2F8NSXFYI%3D&reserved=0 - Topband Reflector _ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
