This edition of the programme discusses how the US Emergency Broadcast System works. This was a predecessor to what is now called the Emergency Alert System. Benn Kobb elaborates and Frank Lucia explains how President Truman gave the go-ahead for the development of the CONELRAD system. Gary Burgeois also explains what could go wrong at 9.33 every Saturday morning. It sounds like stations then were better prepared than today.
The programme also discusses changes to the domestic shortwave service in Australia. Andy Sennitt explains that Nigeria has discontinued some of its shortwave services and the location of Radio Sovereign. Bob Tomalski (known as Roger Tate in those days) reports on DAT digital recorders.
The tape of this programme didn't survive as well as others, which explains the slightly higher level of hiss than other editions at the start of the programme. But it quickly gets better.
