Hi Graham, Spiros,
I don't think Spiros' electrical antenna would have significant
directivity. The reason for the missing reports from east Europe is
most likely Loran interference on his TX frequency 137550 Hz (as
mentioned as "dial" in his earlier email).
All stations of the Russian Loran chain (GRI 8000) emit discrete
spectral lines on multiples of 6.25 Hz. These are already significant
here in Germany, and would be much stronger further east. In Western
Europe, the relevant chains are Lessay (GRI 6731) and Sylt (GRI 7499).
Line frequencies which should be avoided appear on exact integer
multiples of 50000/GRI.
If you used Opera's automatic TX frequency selection it would
probably evade those lines which are visible at the TX location, but
it knows nothing of those in distant potential target areas.
BTW it would be helpful if the Op system reported actual receive
frequencies and not only "meters band" along with time and SNR.
Best 73,
Markus (DF6NM)

Ok Spiros
I was 'ok' till I got to 40 mtr vertical ! , 120 feet !
that would explain why !
Glad , the Op system is working for you

Hi Graham.
My output PWR on YUMA is 50W RF.
The antenna is a 3 parallel wires 28.00 m long (50cm distance between
wires) and aprox 40m Vertical.
Marconi “T” type antenna.
Tnx

Good results Spiros !
What is the RF Power ? , do you think you have a directional
Ae ?

Earlier I had also capture by Mauro *IK1WVQ.*
Also first time my signal heard outside of my QTH into SV land by
Leo,SV2DCD .
