Possibly to limit interference. The proposed site is significantly inferior, being about 600m lower, with no change in power (although I understand 3NNN has been operating well under power anyway).
I have used the Nautel coverage tool to make the following predicted coverage maps, with a few assumptions. Don’t take them as gospel for actual coverage, but they do show the difference between the 2 sites (I used the exact same specs for both sites, which also match the existing and proposed specs where relevant).
3NNN Existing coverage from Mt Stanley:
3NE Proposed coverage from Taminick Gap
As you can see there’s a significant reduction in reception in Wodonga and out east around Bright.
It’s also possible that ACE have requested this site to manufacture a need for an infill in Wodonga.
With the reduced transmitter height that’s probably not going to be as significant as it would have been from Mt Stanley.
Definitely. ACMA seem to have an approach of not removing existing infills, and trying to get as close as possible to similar reception in the fringes of the licence area, even where the existing FM’s don’t have reception and those areas are served by an neighbouring licence area. It generally results in more infill’s being required, and therefore less efficient use of spectrum.
3NNN has great reception throughout the licence area and further with their main TX on Mt Stanley and a lower power repeater at Mt Beauty. It would be so much easier for 3NE to be given the same setup.
The Wangaratta licence area includes approximately the western half of Wodonga, so theoretically they have the right to be able to reach that audience. I agree it’s a bit of stretch though, especially given the current arrangement with 2AY.
I’ve also found 2AY so have some of the clearest AM reception I’ve heard.
ACE would want the Wodonga infill as a pseudo FM conversion for 2AY. It’s going to be hard from them to get an FM conversion for 2AY, but with 3NE having almost identical content, including the breakfast show, they could run the 3NE infill with a separate feed with Wodonga ads and they basically have the same thing with a lower power. Is it right? No. But it’s the same strategy they and other smaller networks have used previously.
Definitely. Much easier to plead the case of “poor us, you’re reducing our coverage” now when it can only be based on theoretical projections rather than real world experiences.
