I've just received the following email from Adrian at RNZI. Good luck!

Cheers, Chris

If you are fortunate enough to have a DRM capable receiver and
live in the Pacific Region here is an opportunity to check out your DRM
receiver as we will be testing on -

Date: Thursday 19 Jan
Time: from 1420 NZDT approx for 45 minutes.
Freq: 15720 kHz

That is Wednesday 18 Jan if you are on the other side of the dateline

Reports good or bad are welcome !

Which is when in UTC (date and time)?


16-01-2006, 19:03
NZDT - New Zealand Daylight Time, UTC+13, deduct 13 hrs... on 19th Jan. In which direction and how many kW?


17-01-2006, 05:52
50kW to "the Pacific". I think this means 35 deg azimuth.

Adrian doesn't expect anyone to hear it outside the Pacific region, so there is a challenge :-)

I wonder where you take the info from that the test is not still scheduled for today?

What Owdjim has published is just the new regular schedule, no word about any change concerning today's test in it.

I did get FAC and SDC lock so for the first time ever I saw a "Received Time and Date".

I goofed with antennas, filters and preamps, but just couldn't get any audio. Oh well!

19-01-2006, 21:31
Nothing heard here in Wellington. I could see traces of the DRM signal in the input spectrum display, but I'm in the wrong direction and wrong distance for this frequency.

Nice blank graph attached :-(

RNZI will test 25,26 jan.(next week)
please read RNZI's web for -
more informations.

I have started a thread in the "Reception Results" section for this test.

It is probably a more appropriate section now that you are receiving RNZI DRM :-)

hi chris
I did not find 17675KHZ for RNZI-
at HFCC.org.
Is that ture 17765KHZ for
testiing 25,26 jan testing?

22-01-2006, 02:10
17675 kHz is used for the AM-mode service to the Pacific:

2236-0359 17675 16 All Pacific 0 Daily

The email from Adrian does say 17675 kHz will be used for the next DRM test.

Cheers, Chris

Hi Chris
Thanks rpy.
So 17.765KHZ is too bad for me.
There are many noises in my location.
on 15Mhz to orver 19Mhz.
How about your lation?
But now RNZI(analog)is coming on 17765KHZ in Japan.
It is 20db to 30dB orver S-9.
If no signal noise is about S-9.
Maybe coming wensday noise will
be same level.
Tnaks chris

For those interested, some information about and pictures of the antennas used for these transmissions at Rangitaiki can be found here (http://www.rnzi.com/pages/technical.php). Click on the pictures to see them at larger resolution.
The text however does refer to the AM transmitter.
