Just back from a trip to Napier/Hastings.  Heard your transmission Graham for the 2 minutes I had free.

The usable frequencies are definitely 88.1,88.2,88.3 & 88.4.  The guardband is officially 88.0 to 88.5 but there is a limit on the field strength allowed outside the band.  I've only got the old RFS29 spec here but I doubt it has changed.

<quote>
Spurious emissions on any frequency not within the ranges of frequencies specified in
section (1) shall not exceed 60 dBmV/m at 10 metres (-55 dBW e.i.r.p.). The emissions shall be
measured with a spectrum analyser or test receiver, with a bandwidth conforming to the
following table:
Frequency Band Analyser/Receiver
Bandwidth
< 150 kHz           200 Hz
150 kHz to 30 MHz     9 kHz
30 MHz to 1 GHz     120 kHz (this is the one concerning us)
> 1 GHz               1 MHz
</quote>

Centering a carrier wave on 88.0, for example, would put way more than -55dBW at 87.880.

Yes interesting situation.

 

I thought that the tawa station Generator was 88.50 as reported to me by one of my

presenters just before Christmas...although I stand to be corrected.

 

As I see it, you can read section 4: of the Notice 2003 two (2) ways, depending on

how you look at it:

1):    "Transmissions Must be contained within the following range of frequencies"

88.00 - 88.50 inclusive.

or

2):    "Transmissions Must be contained within the following range of frequencies"

at frequencies above 88.00 and below 88.50, based on the 0.1 seperation.

 

Urgent clarification is required on this point, as there is NO indication within the framework

of the Radiocommunications Act of 1989, and subsequent documents, that indicate that

you can, or can't use what is defined as a "Greyline" frequency ie) a frequency that is

used as a boundry indicator ie) 88.00.It is noted that Full and clear clarification was

issued in the document by Katherine Moody in May 2002, as regards to the actual frequencies

that can be used at the time June - Dec 2002.

This however has not been as clearcut in the "New" document released by Adam Freely on

the 4th Dec 2002, for the period Jan 1, 2003 - June 30th 2003.

 

Comments are most welcome

 

regards

 

Graham

I think you'll find the tawa station is on 88.4 now. sorry, I can't confirm that though.

 

Like I said before though, to remain consistent, if they say we can use between (but not including) 88.0 88.5, then surely the same will apply at the upper end, too? IE: use of only 106.8, 106.9, 107.0, 107.1, 107.2, 107.3. Will we now loose 106.7 too?

 

Cheers,

Bryan.

Yes I agree

 

Don't The Generator operate on 88.50 from the Radio Training School, as well as Radio Lakeland

in Tokaroa, also why are there still a lot of Tourist Info stations still on the 100 - 101 Mhz Band ?

 

Carefull answers would be appreciatted.

This is really quite interesting...

 

So, it could either mean the 88.0 + 88.5FM frequencies are now included, or (if I'm reading it right) that if the 88.0 + 88.5FM frequencies are excluded (as is currently the case, and was apparently always the case here in Wellington), to remain consistent that 106.7 is no longer available, but 107.4 is?

 

It seems as if 107.4 could either be used by a 300mW (LPFM), or 25mW(Real estate) device just by looking at the regs below... None of this seems to clear. It seems to be channel specific with 106.63, but all the other frequencies are rounded. So, maybe 106.7 isn't acceptable, but 106.75 might be (given the bandwidth, and channel spacings)? It's all a bit odd, really....

 

Maybe Andrew, our friend at RSM can help cast some light on this, if he's available to?

 

Cheers,

Bryan.

Try again..

 

Hi to you All

 

I noticed in the New Regs current till June 30th, 2003

 

that:

 

I note a couple of differences in the old freq Range for the Document issued May 2002

which says that the freq range shall be: 88.10 - 88.40

yet the new Doc issued Dec 2002 indicates 88.00 - 88.50

 

Is this correct ?
