What I have learned • Sans Souci may well be a ‘better’ location for hearing Australia than Grayland in the summer • Domestic station interference is a larger factor in determining what you’ll hear than wanted signal strength at these similar coastal locations • Short-term fade patterns and daily variation between the two sites hides long-term trends • Murphy is EVERYwhere! – The unattended listening location – Grayland - was subject to – over-twisted wire nuts (2013) & a power outage (2014) – ‘back home’ was subjected to Mac/PC – USB/Thunderbolt incompatibilities resulting in lost files
