I had great fun in the Ukrainian DX contest with low power. The 20 m, 15 m and 10 m bands were doing very well. I used a power of 2.7 W down to 36 mW and an Inverted Vee. I used the lowest possible power in each QSO.
I love these DX contests, in which I can work any station that I want.
I found out that 20 meters is still the best band for milliwatting.
