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
1 Mult = 1.9 Q's
3 Africa ( of 6 possible)
just before band closing nowadays very rare USA workable
