Following on from the post about the curious case of the jamming of Uncle Scrim, here is a story that appeared in the October 1990 DX Times penned by Barry Williams.
THE JAMMING OF 1ZB
When we talk of jamming we tend to think of the Cold war during the 50s and 6os on shortwave when there was a real battle of the airwaves between the East and the West. However New Zealand had a case of jamming much earlier than than that.
There have been a number of significant dates affecting MW stations and therefore DXers, in New Zealand.
1919: the first experimental radio station started broadcasting in Dunedin, New Zealand when founder “Toots” Mitchell was presented with a triode amplifying tube by his engineer friend Edward Meining. The opening song was “Robin Adair,” sung by Mitchell’s girlfriend at the microphone while Meining pedalled his bike the three kilometres from the sending station to his house where he had built a receiver. The station later became 4XD. They broadcast intermittently until 1921, then started regular scheduled programming two days a week. Those broadcasts led to the start of the Otago Radio Association. 4XD is still broadcasting, now on 1305 kHz and 99.2MHz often using the slogan “We were here first.”
