XR0Y expedition

Tomorrow I will leave for Chili > Easter Island.
The expedition will be ‘holiday-style’ so there will be also time to visit the Island (do they rent bicycles there?).
Also I want to do some diving, water temp 22C is fresh but visibility seems to be very good (50m??!!!)

I will not blog here about the expedition. There is a perfect site maintained by Stan, with videoblogs, logs and so on.

XRoY website. And also on twitter.

Hope to meet you (I will be mainly on SSB)

I didn’t know this: 1st place in contest!

CQWW 2009 SSB

Just back from an assignment from India. When I came home I found out that the 160m inverted-L was destroyed by the cows from the neighbor.  Not sure how they did it. The top-line was across their land but to high for the ladies. Maybe the wind was so heavy (I was not at home, don’t know) that the flex-pole from 16 m was bended so much that the top-line fell to the ground.
Yesterday the farmer brought 40m alu wire back to me.
So no 160/80m for me so I decided to focus on 40m and have some fun on the other bands, mainly 15m&10m.

Saturday 15m&10m were open, but not to the North-West. Later Saturday there was aurora on 2m declared, which explains all.
Sunday only 15m was open, 10m only short skip time-to-time.

I made nearly 600 qso’s on 20 active hours (had to play volleyball on Saturday), quite nice with some nice Zones worked on 40m.
Missed Zones like 3/6/19 even on 15m!

Preparing for the trip now to Easter Island. You can follow all the details on the site. Already there are 4 videoblogs running!

New expeditions, new DXCC’s

Wintertime is coming and that’s the time that most expeditions take place.

PG5M Gerben started off in Western Kiribati and Tuvalu. I managed to work him on both Island, on 20m CW. Heard him on a few other bands (30m/15m) but the pile-up was like a wall…

Around the same time FT5GA started on Glorioso Island. I managed to work them on a few bands (12-12-17-20) but not on the lower frequencies. I must say that the jamming by lids is enormous, I never experienced that in my life yet.

After that I worked FO/SP9CYY (French Polynesia) on his way to Austral Island, where I worked him as TX5SPA on 30m.  2 new ones.
And today 3D20CR, Conway reef on 20m SSB.

Altogether not band for 3 weeks DX’ing. In the low bands (40m-160m) results are zero: the 40m beam is to low and my 80/160m vertical has failed up to now.

Experimenting with a 160/80 vertical

Last month I erected a combined vertical for 80/160. On a Spiderbeam-pole (18m) I had made a inv-L for 80m (1/4 lambda, 18m vertical, 22m horizontal slope for 160m), the wire is inside. For 80m the wire was taped on the outside, the last 2m sloping in 45 degrees. Feedpoint was the same (one coax from TX to pole.)

SWR was >>> on both 160 and 80m. So I asked Thomas PA2M to help me with his SWR-measuring tool and after a lot of testing it was clear: this will never work. The interaction between the 2 vertical wires is so big that 80m will never dip in the 3,5 MHz band(best dip was somewhere 5,5 MHz???).

160 m dipps inside the band, bit to high but that is easy to repair. SWR is about 1:3, theory points out that 1:1,5 is the best SWR you can get (with horizontal topline, which is not the case). Measured R is about 25 ohm, so maybe a 1:2 transformation is necessary.

So that made it clear that a brilliant idea failed on trying out. For 80m I have to invent something different.
