Even with SF=73 and minimal band conditions compared to previous years where all of  USA was workable
it was again an interesting event  including nightly antenna work.
And still interesting DX  like 3B9HA and others

 4ele 10 and15m put up for this occasion.  Sunday morning i could see the result in daylight.

Started with low power and dipole S&P  Saturday
Decided to change from dipole to 4 el  that kept me busy Saturday afternoon till after dark
No good timing since Saturday afternoon  and evening held the better part of propagation.
But it was still dry no wind and I thought  the cold i had was cured...

New is a solar panel PV-C  20dB noise   in North direction from west to east.
The last year new PV converter of my  neighbor does generate noise from 1 to at least 70MHz
broad  noise  and  digi spurious each 200kHz  to  9+20 at 14MHz
I have done some noise tracing and found the noise source is concentrated near the display/CPU
of this PV-converter even when there is no solar energy produced,
Just as long as the CPU is active before it goes to idle there is noise coming from the CPU part.
I will not mention the brand since they want to find a solution too and are cooperative.

My house SolarFrontier (other brand)  is clean.
This low QRM environment changed last year
With the 4el it is about 20dB noise at front  still about 6dB at the back
If the solar PV/converter   +  optimizer finally shuts down after sunset
the noise almost zero in the free directions just increasing if antenna is connected
In urban direction south is some 6db increase  distance 5-10km
That can be heard clearly when the PV-converter finally shuts down

    Band     QSOs     Pts    S-P  Cty  Pt/Q
    28           73         292    5     34   4.0
 Total          73         292    5     34   4.0
Score: 11,388
1 Mult = 1.9 Q's

 SF 73  

no Asia very few  Rusia  east was almost closed
3 Africa  ( of 6 possible)
just before band closing nowadays  very rare  USA workable

Goed gedaan Jaap. Kan je zien dat CW het echt veel beter doet. En een goede antenne die hoog staat natuurlijk. 73, Bas
