A little about me and my station's working conditions

My name is Haris and I live in the north of Athens, the capital city of Greece (Locator: KM18VA). I licensed as SV1GRB in September of 2001.
I am using about 30w for digital modes and about 100w or less for SSB and CW.
My antennas for HF bands are a 2x12,7m Doublet and a 28m Long Wire, both of them are positioned as inverted V in different directions.
For 6m band I am using a Half Wave vertical antenna.
My antennas setup is not always the same because I am experimenting very often.
