Antenne work

Since April 2017 i started some major antenna work.

Took all my antennas down, did replace the electric whinch, replaced the cables, new coax and so on. 

Started modeling a new antenna (2 el for 80 m and 3 element for 40 m) and did order 2 OP-DES 14 mhz 5 element yagis.

Since 15 of july some of the new antennas are installed.

The 3 element for 40 m will be added soon.

First test with the 80 m beam really looks promising,worked already VK,ZL,JA,VE,ZS ....

160 m 8 januari 2017

First snow here in ON. 

Came this morning in the shack around seven local time,and i asked myself will 160 m be as good as yesterday.

Well , not that great opening or activity but managed again about 25 NA qso's including several westcoast and midwest,

So great to start the last day of my Holliday break.Tomorrow back to the salt mines !

Hope 160 m stays like it is now....

 

Its just fun to work you guys.....

160 m HOT!

This morning worked about 40 stations in North America and Canada in about 45 min when i started at 7.00 am.

West Coast and mid west were really fine sigs.What a nice surprise to find the band in this shape.

Thanks all for the qso', see below my log from this morning !

160 m nice opening!

Yesterday evening we had once again a very good opening into the Far East ! TOP BAND WAS HOT!

Stations worked : VK3IO,VK6VZ,HS0ZIA,5B4AMM and lots of JA, 9M2AX (but he had no rx)

Hope cdx will even improve on topband.

 

Cuagn sn in CW.

Evaluation 4SQ 3.5 Mhz

After working this morning ZL7G long path in cw 3.5 Mhz i believe this array is really working well.

Over the last months i worked quite a lot of dx with this array Ja,Du,Vk,Zl,Vp2,K.

Cdx has been very poor last months , so i think its a winner.

Update new 4 square 3,5 Mhz

 

Yesterday i found some time to try to improve the new 4 square for 3,5 Mhz.

Like i wrote ealier, the feedpoints are 2 m from ground, and today i brought the radials higher up in the air 

( 4 m high now, gull wing system).

The impedance at each element dropped from circa 46-  48 Ohm too circa 38 - 39  ohm, so less losses to ground, 

( a vertical should have 36 Ohm in theory) so the efficiency of the array is improved.

I noticed a bigger front to back now , specialy to close by signals ( 0 - 400 km),this is what to expect with just one radial for each radiator.

 

Keep you posted.

New 4 square 3.5 Mhz finished today !

After using two delta loops for a season, i decided to install the 4 square for 80 m again,but in a different approach as in the past.

So i did go for Top Loaded wire verticals and make them resonant in cw ( favorite mode).

( 12 m vertical, 2 times 8,5 m toploading wires,sloping towards ground, angle is 45 degrees).

The feedpoint are 2 meters from ground and at the moment just one elevated radial at each vertical facing outside the square.

The advantage of one radial is the easy way to tune for same impedances at the feedpoints.

Along with the comtek coupler is seems to work, see great front to back.

Of course in middle of summer not much dx on the band and also poor cdx the last days, so i have to evaluate the new 4 sq later in the season.

I keep  you posted.

Great Ja opening on 18 Mhz

This sunny sunday morning i had a great pile into Ja in cw on 18 Mhz.

Worked just over 63 ja stations in 23 minutes of operation. Like contest style !!!

Great fun ,certainly when i first tuned around an almost dead sounding band.

Cuagn soon in cw.

No dx since begin April !

I am back active a bit,be off the air for more than a month.

After 6 month of fighting cancer my father is a silent key since 22 April at the age of 84.

Thanks for all Dad.
