Hi All !
It was my fault, there was one bad connection.
I did new tests to day, here are the results:
1842 kHz OK
1873 kHZ OK
3520 kHZ +++++
3785 kHz +++++
7003 kHz OK
7098 kHz ++
10116 kHz ++
14030 kHz ++
14330 kHz ++
18079 kHZ NOT
18100 kHz NOT
21030 kHz OK
21370 kHZ OK
24945 kHz ++
28510 kHz ++
50000 kHz OK
OK means some SWR but very low
+++++ means perfectly matching
++ means good matching
Only 18 MHz was not working.
Wire is abt 23 m long and from the FC40 wire is goeing first 4 meters
straight up and rest of it horisontally up to 10 meters at the end.
I will take it down next weekend and measure it carefully..
Grounding as I told earlier is not very good:
there is 20 meter loop 35 sqmm copper abt 10 to 30 cm deep in the
ground and in this summer I added 3 m long groundig rod abt 45
degrees angle and some other copper wires.
Not yet counterpoises , that will come later.
I have never used that 18 MHz band, but because it is not working
I have to try something for it ...
