Just something I've always wanted to know,

I'm listening to ZM at the moment and they have a black thunder in Tauranga at present driving around which they are broadcasting in at the same time. I know someone is at HQ in Auckland pushing all the buttons but what do they use to get the remote signal back to Auckland? I remember some years back the same thing being done in Taranaki where the guy was in South Taranaki and getting a signal back to new plymouth somehow

cheers

Are they simply using cellphones? Or is the audio better than this?

In Wgtn most the stations still use WFM links at around 160Mhz back to the station for live or prerecorded links.

Nah def way better than cellphone, I'd say the sound qual is like a very compressed audio stream (like listening to a radio stream on itunes at 32k)
Would they be relaying via their Tauranga office back to auckland or can they get the signal all the way back there?

The radio won't work that far away. My guess would be a radio link to the studio and then back to Auckland.

Most live Black Thunder crosses to the Auckland network head are done via cellphone.

Local Black Thunder crosses are usually pre recorded in advance into the local presentation system and play back as part of a network advertising breakout - often first or last in break.

More advanced outside brodcasts where a network event is originating outside the network head are often fed via dialup units that run over POTS but have pretty good audio codecs in them to deal with the limited bandwith vs desired quality for FM broadcast.

A Comrex Vector is a good example of the kind of kit a number of broadcasters may use in this regard.

Hope this helps Wink
