Doom painting - NOT amateur radio

This painting is in a local church in Salisbury. It was painted when most people could not read or write. It was white washed over in the Reformation (vandalism in my view) and rediscovered in the 1800s. Why do people believe they always know best? It is part of history.

Oscar 100

Loop antennas

Loops work remarkably well. They can be quite small. Their main drawback is they are narrowband so have to be retuned if moving too far in frequency. If using WSPR or FT8 this does not matter. For good efficiency, the inductor is usually made from copper pipe or coax cable.
