Propagation, activity and antenna
When I started as a HAM in 1990 I used a homebrew QRPp transceiver for 7 MHz, which I call the HM7 and an inverted Vee antenna.
In the 10 years that I used this CW transceiver extensively, I worked many European countries with a power of only 500 milliwatts in many normal QSO's and many contest QSO's. The excellent design comes from the book solid state design for the radio amateur.
During the years that I used this TRX, I had great fun and I noticed that the activity on the band is more important than the antenna. With 500 mW the signals of the other stations must be S9 or more. Especially contest stations are eager to work everyone, so many QSO's can be made in a contest.
Further I discovered that propagation is more much important than the antenna. The Inverted Vee is not the best antenna, but the daily changes in the propagation can not be beaten by any antenna.
So to me, the order of importance is: Propagation - Activity - Antenna
