DUCT 6.02.05

Well, we finally got one down in the south east of the country, been well over a month.

This mornings duct was quite a good one and was workable from parts of VK2, VK3, VK5 and
VK7.

The weather was very nice 100% clear sky and virtually no wind. The temp was around 17
degC for starters I think. The dew point reading at Wagga was still +10 degC. I have
checked duct readings and it shows the duct being very high, 1700m at Wagga for instance,
similar at other areas but less than 1500 in most cases. Most unusual.

Again, I was late in finding that this duct was workable! My antennas were beaming SW
towards Mt Gambier all night. The weather map certainly wasn't looking good for anything
to happen. It wasn't until about 7.30am that I thought I could hear the VK5 Naracoorte
repeater that I thought I better turn the antennas west and have a listen.

While turning the vertical yagis and looking for Renmark TV (143.760), it only came up to
S9 which is not all that good. I switched to the repeater frequencies and straight away,
there was Barossa Valley 2 & 70 repeaters (741 Km) about S7. Startled by this, I quickly
turned the 2m horizontals and switched to 144.450 Adelaide beacon, and there it was about
S9!! Couldn't believe it!

I jumped up and sent an SMS message to VK5UBC and VK5ZLX about the duct, but it was too
late, they already knew about it anyway! Again, very poor on my behalf, though I did get
more sleep than I otherwise would have.

Typically, I pulled my new 70cm horizontal yagi back of the tower yesterday for some
tuning. Would have been interesting to try 70cm horizontal on SSB for the first time out
west, but it will have to wait for another day. I also have a 1296 MHz system getting
close.

I went through a few of the repeaters in the west and quite a few were present. My first
contact on 144 MHz was with Peter VK5ZLX in the Barossa Valley area (735 Km). Peter peaked
at 5/9+30 on 144 SSB during the course of the morning, apparently with his antenna still
beaming Melbourne.

Next up was Brian who was 5/6 on 144.100 from Gawler (764 Km). Peter, Brian and myself
tried 70cm FM vertical but had no luck what so ever. I was kicking myself for removing the
horizontal 70cm. Brian peaked up to 5/9 during the morning.

I had Brian call me on Port Lincoln 146.750 repeater (1019 Km), while I could hear it here
at S4 I could not get into it.

I then checked a few repeaters and worked Dean VK5LB on Crafers (764 Km).

Then John VK5PO at Eden Valley broke in on Crafers, reporting that he could hear me
direct, we QSYd to146.500 and made a good FM simplex contact at 731 Km, 5/5 signal, but
John peaked up 5/9 later in the morning.

Back onto 144.100 and John VK5BJE was being heard from Scott Creek (761 Km) at 5/9.

I then found on 144.100 Les VK5JL at Grange (782 Km), Les peaked at a 5/6 signal and is
locaated on the western side of the Adelaide Hills near the ocean, so was doing well
getting over the top. I remember that Les worked VK6WG during the opening last March.

Found Barry VK5KBJ on Willunga Hill repeater 146.675 which was S9 here (771 Km).

Next up Richard VK5USB Adelaide area appeared on 144.100 only around 4/3 signal. Done well
from his QTH, apparantly I think in the city.

Interestingly, at 11.30am my time, I was talking again to John VK5PO on the Barossa Valley
146.825 repeater, we had just finished QSO and all of a sudden Chris VK3VSW calls in from
Geelong and then straight after this call, Dion VK7YBI called in (949 Km) also from near
Burnie Tasmania! Only got about one over from Chris before he dropped out as Chris has a
big hill in that direction. Dion was OK coming in over 949 Km to the repeater! VK5PO could
hear Dion direct so they went to 146.550 to try the contact, which I believe they made it
through, this is 938 Km.

On 144.100 worked VK5ZK Garry in Goolwa up to 5/7 (754 Km).

A lot of the VK5 stations were able to work many in the Melbourne and VK3 area. Including
VK3KEG, VK3AXH, VK3HZ, VK3II, VK3FMD, VK3AUU.

At probably 12 midday Dion VK7YBI was then getting into the Crafers Adelaide repeater (930
Km) full quieting, very nice signal and he was speaking with VK5KJJ and myself.

Well done to Dion for these spectacular contacts. Also speaking to Dion about his QTH and
I think that he is bound to get into VK6 on ducting at some stage.

Thats about it. Things began to fade out and were mostly gone at 12.30pm, but the Adelaide
beacon was still present about 1pm but weak.

Also during the morning, just about all of the Adelaide area 70cm repeaters were worked
here at some stage, but were mostly not real good signals with QSB. Was also able to pick
up the Adelaide 432.450 beacon on my vertical antennas 5/1. Would have been interesting to
have had the horizontal yagi up. Maybe next time.
