I recently purchased and built a low cost Soft66Lite kit which is a Direct Conversion (DC) Software Defined Receiver (SDR) the simple cousin of the well known Software Defined Receivers and unlike the early Direct Conversion Receivers of the past, as the mixer stages are based on a Quadrature Sampling Detector (QSD).

A few years back I bought some large VHF Broadside Antennas at a stock-take sale. So during one weekend, I thought I'd just weld up a stand and see if I could use them as a simple radio telescope.
Recently I obtained some blocks of Plastic Scintillator BC412 which measure 89mm x 89mm x 38mm and is ideally suited for detecting muons.
I loaned my 3 Tube Muon Detector to Sebastian Tomczak who has rigged it up for some experimental sonification.
