Re: [LPFM] MED Discussion Paper on VHF-FM Broadcasting: FrequencyAvailability an

Thats a good point.

I believe this is the very thing thats going on with 'rejigging' of
medium powered frequencies up north by Canwest. Co-channel freqs
broadcasting the same programme, to achieve bigger coverage at the
expense of middle zone interference.

This could have been done by government when allocating the Niu FM
frequencies in the upper band. These frequencies were not in use
anywhere in the country, so theory suggests this could have been
implemented from the get go, but decided against for some reason.

Instead the new licenses were positioned mostly around the 103fm mark
where possible. Same thing with National Radio (101fm).

They would have to re engineer the frequencies ie if Concert was on 89.0Mhz then unless the 400Khz spacing was removed Mai and 1ZB 89.4 would move accordingly...
