In the end of January I participated in the REF CW contest.In recent years I made many QSO's in this contest with 50 mW.
The top of my inverted vee was broken last year in a storm and I made a temporaly repair. One of the wire lays on the roof.
So I had to experience how the antenna would work.
On Saturday I made 2 QSO's on 20 m with 50 mW and 100 mW.
On Sunday I made 14 QSO's on 40 m.
In these QSO's I had to use the full 5 watts of the FT-817 due to the antenna.
Further I made a number of QSO's on 20 m with a power of 50 mW to 500 mW.
The inverted vee with one wire on the roof works for 20 m.
But on 40 m it takes more power to make QSO's.
When the propagation is good, it's not that difficult the make QSO's with very low power.
On Sunday the signal of F6KNB was S9 + 10 dB. So I decided to try a power of 50 mW.
I gave my call just once and got an immediate respons. FB.
