Monumental science

It’s not commonly known that the Monument in London was constructed not only to commemorate the great fire, but also as a scientific laboratory. Two of the great scientists of the day, Hooke and Newton performed experiments in basic physics and materials science.
Yesterday evening, some physicists, myself included from Queen Mary University visited with the intention of performing the first experiment at the monument in several hundred years.

We were successful!
The real science will start once we’ve made the equipment modifications needed for easier operation in the basement lab of the monument.
More to follow as it happens.

VHF Radio Coverage

I’ve just discovered a nice tool for plotting radio transmission coverage. Here’s where I can expect to get a signal too from my home location.

Where 100 watts of 145 MHz RF will get, from my home QTH
Where 100 watts of 145 MHz RF will get from my home QTH

Yellow shows 0.50 μV signal level, Green is the 1.58 μV signal level

This seems to match up quite well with contacts I’ve had on the two-meter band, but with less power actually used. I’ll have to play a bit more and see how it says my station will perform on other bands.
