3h 46min of nearly perfect reception after a 10 minutes weak start. I also noted a couple of dropouts due to electric drills and other tools outside here this morning. :rolleyes: Work outside stopped around 0945 UTC.
This morning's reception - 76.86% audio decoded, 19.33 dB max SNR.
"Only" 2h 30min of perfect reception (0916-1147) this morning. The max. SNR was at the very beginning of the last transmission. 81.5% CDA for the whole transmission.
This morning's reception - 85.70% audio decoded, 19.48 dB max SNR. With an unexplained signal outage at about 0950.
This morning's reception - 89.26% audio decoded, 20.73 dB max SNR.
No good at all today, a weak start and two weak endings. Only 61% CDA for the whole transmission.

2h 49min of fairly good reception:
3 h 35 min of perfect reception. Probably would have been a few more minutes, as I had forgotten to turn off a noisy LED lamp power supply made in you-know-where... :rolleyes:
By the way, the dip around 1011 UTC must have been TX related - I noticed it in FritzWue's log too.
This morning's reception - 64.38% audio decoded, 19.82 dB max SNR.

Strange, the clock is UTC but the date New Zealand.
More than 3 h 35 min with >99.2% CDA. SNR peaked at 22.53 dB around 10 UTC.
This morning's reception - 59.22% audio decoded, 19.17 dB max SNR.

3h 28min of good propagation today.
The problems at 09:20 UTC were caused by interference, see SNR Spectrum screenshot.
Additionally there is a communication system on air that is using second long data bursts which are hopping all over the band and sometimes also hit the RNZI signal. :mad:
(DX Tip: At 12:00 UTC Adventist Radio Guam starts at S9+ here in AM on 9880 kHz.)
I want to go back to Sweden! :rolleyes:

Worst reception result since weeks. :(
Low signal strength and high doppler values.
Probably the sun's activity is really too low today.
A happy new year and all the best for 2012 to everybody at RNZI! :)
The last log for 2011 in Switzerland isn't very pretty either. Doppler values above 1 Hz usually silences my audio output here. Broken audio from around 1100 but it did not last very long.
This morning's reception - pretty good apart from the periodic blips - 86.26% audio decoded, 19.92 dB max SNR.
Happy New Year!

The reception is definitely much better in Sweden than in Switzerland. In Switzerland I got a few syllables of audio just before the end of the transmission.
Unstable with quick wobbly fading at the beginning here and then >99 % CDA after 1035 UTC.
I still can't figure out why the csv log time stamps are dragging - for every hour I lose about one minute compared with the system clock. :confused: :confused:

Bad propagation conditions today:
Not good at all today. Doppler was all over the place. On top of that there was no audio for a longer period - according to Dream there would be, but the audio spectrum was nonexistent.
Best parts of log 34min. from RNZI today.
This morning's reception - 45.25% audio decoded, 20.10 dB max SNR.
This morning's reception - 74.23% audio decoded, 19.86 dB max SNR.
Better propagation today from RNZI. Log 1h.
I am not sure how to explain this first log from Japan in 2012. Seems to need some re-thinking about where to put the antenna in regard to plasma TV, chinese LED lamps etc. :confused: :confused: :confused:
This morning's reception - 66.61% audio decoded, 19.21 dB max SNR.
This morning's reception - 71.40% audio decoded, 19.07 dB max SNR.
Today I changed the location of the antenna, which seems to have improved the reception a bit. However, I am not around a lot, so the log for today was mostly unattended. The plasma TV was off. The chinese LED lamps were on. The reception looks very good despite the very high doppler values at the beginning of the log.
Better propagation today .log 1h 55min. MAX SNR 24dB.

Oops, I had my logger programmed to switch off at 1200, so I missed the extra hour. Good results despite the Plasma TV QRM: 99% CDA for 3 h 55 min.
No bonus today. Peculiar pattern in my log from 11 UTC.
This morning's reception - 64.45% audio decoded, 19.84 dB max SNR.
The transmission started late, and I kept the log for the extra hour as an SNR spike showed up at about 1257.
RNZI in AM still now at 0843 UTC. :confused:
FritzWue
03-02-2012, 10:07
They shifted the AM service from 9765 kHz to 9870 kHz, so no DRM today.:mad:
FritzWue

Again no DRM on 9870 kHz today and AM on 9765 kHz has terrible fading today. :(
I was out turning the city upside down, and my unattended log only confirms Fritz's post.
Just came in and had DRM on 9765 kHz, but only for a minute or so. :confused:

As I said, I caught a piece of DRM on 9765 kHz an here is my log... Just after I started the log they shifted to AM. :rolleyes:
FYI: The QRG in my log is NOT correct; I had prepared for the regular transmission, that's why.
No DRM reception from RNZI on any of their regular frequencies this morning.
All systems go at the beginning except for two audio outings but the transmission broke down within the first half hour. What is going on?
The log was on for another 4 hours with no signal to be seen. :confused:
This morning's reception - 7.79% audio decoded, 18.40 dB max SNR. As Terje noted, the transmission closed after the first half hour.
High doppler impaired the decoding after 1030 UTC.

Today there was strong interference from a non broadcast station,
at first a broadband signal, later fsk teletype.
At 10:41 UTC I put a widened notchfilter on that signal
which made RNZI decodable for 1h 18min. :cool:

Hi Terje,
congrats, very good reception at your location today.
I know the advantages of your DRM Plotter, but I am starting and stopping my logs manually.
So I often forget to stop it in time.
Nevertheless I want an exact log starting and ending with the transmission period
I want to report to get right results.
Editing DreamLog.txt for that is easy, but I fear editing DreamLogLong.csv is a nightmare. :D
Nevertheless I want an exact log starting and ending with the transmission period
You can use the zoom feature to achieve that...
This morning's reception - 82.02% audio decoded, 19.32 dB max SNR.
Exactly Zyg, I did that tonight as I forgot to switch off Dream (or, I stopped the Autoplot, so the Dream Auto Shut-Down became disabled). So I used the Zoom Stop feature for this log.
Tonight was even better, Fritz, 99.82% CDA for 237 minutes and the max. SNR was 23.26 dB at 10:45:24 UTC depite the fact that the 300 Watt Plasma TV monster was on. :)
99.75% CDA for the whole transmission and max. SNR was 24.10 dB which must be a record for this receiver. At least one of the better results ever. Very high doppler values in the beginning. :confused:
This morning's reception - 70.97% audio decoded, 20.14 dB max SNR.
This morning's reception - 62.05% audio decoded, 17.98 dB max SNR.
Roller-coaster Doppler here this evening and a weaker signal than usual during the last hour plus the horrible plasma TV QRM brought down the decoded audio to 99.32% :rolleyes:
This morning's reception - 84.99% audio decoded, 20.37 dB max SNR.
99.3% CDA and max. 23.13 dB SNR which is good. A lot of music that could have been left out for better music. Rap is not music. To me that is a load of rubbish.

Better today, 59 min of acceptable reception.
Early there was an AM station on 9895 kHz splattering all over the band with its modulation peaks.
Hi Fritz and all,
I have problems at the beginning with a Chinese splatterer that chews into RNZI's spectrum, but despite this I logged 99 % CDA for the entire transmission. :)
But soon I'll be back to 18E, so we'll see then...

Thank you Zyg, we arrived back in one piece. However, the reception of RNZI here up north is not the best. The last hour started out fine, but then the signal suddenly weakened and the last 20 minutes were a complete loss.
