This is a very different location to the copper mines I visited near Porthtowan on the first trip as it was a tin mine. It's actually one of the mines that apparently wasn't completely exhausted and was shut due to financial mismanagement. Now it is well overgrown but still with quite of a lot of visible infrastructure. This was trip was initiated by a discovery..."

In the first two the modulation is controlled by a normal transistor, the last one is modulated by a crystal. It requires two cat's whiskers and the way it is set up with the crystal connected to the input of the inverter and to ground via th..."
