Summer at last?

Here in eastern England we have had a bad summer so far: it has been very wet and temperatures have been lower than normal. Oddly, my brother in Devon has had a good summer. Next week they are forecasting warmer weather here with sun. Temperatures of 25-22 deg C are possible here. The jet stream has been right overhead and we have seen low after low roll in with very few long sunny spells. Maybe things are changing?

10m Antenna Effectiveness

One of my hobbies is amateur radio.

Comparing my 10m (28MHz) signals with those of others, I suspect my antenna may be down in effectiveness compared with better optimised systems. My 2W is equivalent to 200mW from the better equipped stations. When fitter (my darn stroke) I may try changing the 10m antenna for something better. A vertical 1/2 wave would be less directional on transmit but might be noisier on receive.

At the present time, my poor state of health is preventing me doing too much outdoors. For example, climbing a ladder  is quite out of the question, so I have to live with the antennas I have.
