First, the massive receiver would have been too insensitive to detect solar radio emissions
; second, kilometric radiation is blocked by the Earth's ionosphere, a fact unknown at the time.
Following an introduction to the meeting from Paul Hyde (RAG Coordinator), Tony Abbey described how a cheap commercial satellite finder can be used as a radiometer to observe solar radio emissions
. Jeff Lashley then gave the first of his excellent presentations entitled 'An Introduction to Radio Astronomy', identifying the different physical processes which give rise to emission in the radio spectrum.
In the summer of 1951, John Bolton and Bruce Slee were working at australia's Dover heights radio-physics field station, near Sydney, monitoring solar radio emissions

. Bored, they secretly began hunting for other celestial objects producing radio waves.
Hey had serendipitously discovered solar radio emissions
while investigating the source of radar static, much as Karl Jansky a decade earlier discovered radio emissions from our galaxy while studying the source of atmospheric static in ship-to-shore and transatlantic communications.
