Sure is satisfying when training and traning pays off.
JK2015 fully erected up 23 meters or so….
More antennas up including Create 80 m dipole
To have something on 80 m for Europe is highly desirable. In additon to the 27 m free standing vertical.
Here is the Create 17 m long shortned dipole with about 0.5 dBi of gain compared to a full size dipole.
Here the JK2015 with the 3 element 40 m yagi.
And the antenna JK2015 is up – now we are ready for competition!!!
After some hours and planning finally the first step is accomplished.
The JK2015 on top of the 24 m HD ALU tower.
Final assembly of the new JK2015 stack
With help of my son Oliver SA5ODJ we finally could assembly the first of the JK2015 antennas.
Here just on ground at 2 meters height. Below the nice flat elements showing good element design with no sag.
The complete antenna on ground. We did this to find the optimum balance point for the boom to mast plate.
Then time to assemble onto the tower mast.
It takes 10 000 hours to be best they say….
It is common knowledge among trainers and researchers that it seems to take 10 000 hours to be best in many areas like music, sports etc and I guess CW is closely related to this empiric fact.
So we need to practice. There are many methods on CW – here is a new one I discovered made by NO5W – “the Pileupnetplayer”. I just started a session on Dayton 2017 and here are the results compared to the best in class (at least those who there ).
At top you see the best player at Dayton an bottom my scores.
Measurement of JK2015
Here are the results at 2 meters height:
Almost flat SWR!
Almost flat SWR!
When raising the antenna the resonance will move up some 100 kHz.
Building a new “killer antenna” JK2015
To be able compete you need good antennas. With a low sunspot 160-20 m and sometimes 15 m is the bands to go with. We have good antennas on 160-40 m but here is latest addition for 20 m and 15 m. A stack of 4 on 20 m and 5 on 15 m.
Here is the process of assembly and test:
2BSIQ SO2R with Flexradio-6700 and N1MM+
To be able to work high rates on contests there are several techniques. Popular is of course SO2R but there several methods to accomplish this. Jose CT1BOH suggested the 2BSIQ technique which is quite attractive.
The fundamentals are:
1. Send TX on radio A and listen with both ears on radio B.
2. When you end TX on radio A you get stereo mode and hear both radios in the ears.
3. When you start TX on radio B back to both ears to radio A.
All this done automatically w/o tilde button.
Here is a video demonstrating it. There is no CW side tone sound as you always listen to other radio for callers while sending CW on the other radio.

Finally we got the results even though as raw results:
