I've just finished reading Bob Brown's (bobnm7m@cnw.com) new 'Long-
Path Propagation Revisited' book. This is a great resource for anyone who
would like to understand more about propagation phenomena, especially
on the low bands. Bob has done a great job of explaining many of the
physical processes that influence ionospheric propagation and showing
how these processes can make longpath propagation possible, or
impossible, on different frequencies. The book focusses on 160 and
shows how propagation on this band differs from that on higher
frequencies. His analyses of the VK0IR and ZL7DK logs show the limits of
distance achieved on 160 by these expeditions and demonstrate how the
theoretical principles apply to actual situations. Thanks Bob!
