CQ WW WPX CW 2015 result.
Here is my result for the 2015 CQ WPX Contest.
80 meters QRP is really hard to do with minimalist vertical antenna.
I achieved something beyond my expectations.
See you in the CQ WW CW at the end of November.
Going MID: experiences after about a year of MF condo station. The TX antenna.
I've decided to write some notes about my (little) condo experience in the MF world because many people think that We need a lot of space to work these frequencies.
Today I'll write about my TX antenna. It's a classic inverted L, it's only 9 meters high and it has an 11 meter long single wire hat.
The position is really not elevated, the base is about only 2 meters from my terrace.
To get better performances I've put the loads the higher that was possible.
Starting from the base, where there is the variometer, the wire of antenna goes up for about 5 meters, then came back down for other 2,5 meters, then goes up again rolling up around the main fishing pole. At this point there is a 15 cm 3 layers coil, not so good for getting best performance, but...
The wire continues toward the tip of the rod where it'll become the horizontal hat for other 11 meters about.
I've only one random radial, 15 meter long about, and a connection to the ground.
This ground connection gives me a lot of noise making reception almost impossible. Without this ground connection the antenna is a very quiet antenna for receiving, too.
Transmission power without grounding worsens drastically.
The variometer is remote controlled by a stepper, but about this I'll speak later.
P.S.: sorry for my english... HI
