Hi all,

the signal was always at its limit with the HAM-yagi, 2 db lower with my omni directional antennas and no decoding at all then.
I think the signal comes over long path. The 2nd attachment attachment shows the SNR when I turned the antenna to short path (dip at -4 minutes). But I have to say "think" because I don t know the directivity of my HAM-yagi on this frequency.

I logged RNZI with the Perseus and the DRT1. Both receivers shared the same antenna. I used the notchfilter of the Perseus to suppress the AM-carrier in the center. 1st graph is Perseus, 2nd DRT1

A liitle better here, 97.6% CDA for 1h 35min, but the season is over.
The signal was there from the beginning, but it took 8 minutes until the sdc was decoded.
The old text messages from months ago are still running, and there is more or less onchannel am interference all the time.

Slightly worse here in Switzerland than in Germany. When Doppler is higher than 1 Hz there is no chance of any decoding.

Hi Everyone,

Here is last night's log from my experimental wideband loop combined with a zero IF I/Q detector. The loop amplifier and detector are mounted on the same board with the 14" loop directly wired to the amplifier. The unit is powered with 4 AA batteries. The IF out cable runs to the computer (located about six feet away).

For RNZI, the circuit uses a 39.46 MHz CMOS oscillator driving a 74HC4017 which controls a 74HC4066 switch to provide the I/Q signals. The HC4017 requires a voltage higher than 5.0 V in order to divide at these frequencies - and is not recommended for designs much above this frequency. I think I'll be looking at the LVC series for the next design iteration. (As an alternative, for higher frequencies, we could simply use the third harmonic of the fundamental to lower the local oscillator frequency; however, that would require more narrow filtering and would deliver lower signal levels).

Still, pretty encouraging results from such a simple circuit.

Mark

Digger
05-03-2009, 09:04
The signal is just a bit too weak here. The Doppler hovers above 1 Hz and the CIR is not more like a wide heap instead of a pulse. :(

Digger
18-11-2009, 11:03
The signal improved during the first 20-25 minutes or so, then a period of perfect decoding followed until the co-channel QRM started. By the way, the reception of RNZI on 9.765 MHz in AM is still perfect now on a clear channel at 1055 UTC. Good, reliable old AM !

21-12-2009, 12:15
Maybe but your post made up my mind, I am going to stick to my original plan and mod my R-75 if the Elektor is really not that good over that long a distance. The DRM hiss of the transmission normally hits levels as high as S-9 but the best I can do with my unmodded receiver is some metadata decoding and that is basically it.

Digger
22-12-2009, 08:49
Now I use the SoDiRa software with the Elektor and that works a lot better than with the G8JCF software. Plus that I noticed that there is a splattery Chinese (?) TX 10 kHz up starting at 08 UTC, which completely ruins the reception. :mad:

FritzWue

Here is the whole lot from this afternoon. The periods with no decoding is entirely to blame on a splattery Chinese TX 10 kHz up.

This chinese TX 10 kc up os a real pain in the neck. Either it is just a carrier or it is a chinese chatterbox or it is a chinese firedragon which kills RNZI completely. Or sometimes it is off the air. Grrrr.

Digger
26-12-2009, 11:50
A somewhat mixed result. Thanks to RNZI for the nice Christmas songs that we definitely don't hear here in Japan. :)

I was not at home today, but those old outdated text messages (Per) are getting on my nerves.

Hi all.


Good signal to AM start on 9870. Log 30min.

Digger
04-01-2010, 10:07
This will be the last log from Japan this time. I was not happy with my Elektor and the antenna I put together hastily before I left Switzerland. Next year I'll bring my National RF-B60 or buy a FRG-7700 on E-Bay here !!!

See you again back in HED land...

FritzWue
04-01-2010, 12:40
Terje, I wish you a good flight back.
Unsteady conditions here today, varying SNR, but over three hours of good reception:

FritzWue
06-01-2010, 12:19
Low SNR with an early CDA decline today:

Digger
07-01-2010, 13:08
Thanks for the good wishes Fritz, I used all of them!

Btw, at 0858 here in Switzerland I heard nothing but AIR, which was 35 dB stronger than RNZI. :mad:

Unfortunately it did not became any better after 10 UTC either here.

FritzWue
09-01-2010, 12:06
Very good propagation conditions today, SNR Maximum [dB]: 35.0 :)

Hi all.

After short QSO on 10Mhz with ZL2AGY Tony in Hawera South Taranaki , so tune I down to RNZI .
Good signal 10:00UTC but go down after 30min and AM take over freq.

FritzWue
10-01-2010, 12:09
Quite good for 150 minutes here today:

190 acceptable minutes:

Digger
13-01-2010, 14:19
Fritz, interesting that you don't seem to experience any co-channel QRM from AIR. AIR ruins my attempts to listen to RNZI completely. :mad:

FritzWue
13-01-2010, 15:03
Terje, here the radiation pattern of the receiving antenna is nulling out the interference. I am lucky that one of my wires is running in the right direction. Reception is worse when I use both wires as a dipole or the other wire alone. :)

I checked here this morning and could not get the SNR above 8 dB. The channel was clear. :rolleyes:

This is what it looked like here this morning. :(

FritzWue
24-01-2010, 12:06
Terje, that's too early. Signal is strong then here also, but no decoding yet.
Most time that starts after 09:00 UTC.
Good again today, I like the programs about the musical aeras and careers.

FritzWue
25-01-2010, 12:23
Good again:

Digger
25-01-2010, 13:53
Fritz, I wish that would have been the case, but there is too much co-channel QRM at my location.

The Doppler was lowest and the SNR was best around 1140 UTC. 0.5% CDA is a little bit on the low side. :rolleyes:

12-02-2010, 14:19
Steady signal here this morning, but too weak and the Doppler stayed above 1 Hz which guarantees NO decoding.

FritzWue
13-02-2010, 12:17
Almost two hours here today:

Very good (85.47% audio) except for the last half hour when an adjacent analog signal at 9865 kHz seemed to cause problems. Although the propagation may have changed at that time with the result that the adjacent station then started to appear.

FritzWue
31-10-2010, 12:28
RNZI also welcome back in europe! 99.6% CDA during the last hour. :D
When switching antenna at 10:58 UTC All India Radio is readable here in AM on frequency,
so my log is split into two parts for checking that.
The transmission to the northwest pacific after 11:00 UTC was better decodeable here. :)

Digger
31-10-2010, 13:28
Here in Switzerland the (most certainly) AIR was much stronger than the RNZI signal. AIR signed off seconds after 12 UTC. According to the list, there is only RNZI listed, but there you are. :rolleyes:

FritzWue
31-10-2010, 15:40
AIR signed off seconds after 12 UTC.
@Terje: confirm, heard that too. My L-antenna obviously has a minimum to India.
Last winter the problem was the same. :rolleyes:

FritzWue
01-11-2010, 12:16
Better than yesterday.
I did not notice any difference at 11:00 UTC, 111 minutes with over 99% CDA.

Hello All,

A report from France.

The result was better and better up to 11h30TU when Radio Vatican started their transmissions on 9865 kHz. Even with 14 to 15 dB of SNR, the receiver was not able to decode RNZI.

Best regards

The first half of the transmission was excellent, the rest was not - 52.79% audio.

@ Fritz: I meant, they are not listed in the OFFICIAL list. And it is good to know that they also transmit in "DMR" on 6 MHz. :rolleyes:
I wonder what they mean with "AIR, its audio site that redefines internet broadcasting"? Do they plug the AC mains socket into the mike input there as well? :D

Brendan1
04-11-2010, 12:37
Here's my log for the first time in several days. Pretty good until the band closes, or AIR comes in strong here (I'm asleep normally when this is on, so I don't really know :rolleyes: ).

Here's last nights log. I found that Vatican Radio is booming in here on analog for the last hour with a broadcast in Italian for Latin America on 9865, and that would appear to be what's killing my reception here.

FritzWue
06-11-2010, 12:13
Good reception for 3.5 hours today. :D
The clock shows the right date now. :)
The second screenshot shows the switching from 11675 kHz to 9870 kHz.

Wav... fantastic signal today.
Log start 0850 from 44dbuV , 0919 up to 64dbuV=S9+30db ......:) :) :) :)
1039UTC peak AIR on S9 on aktive antenna so I switch over to INV.V Nr1. and AIR restrain -10db and DRM go on to 1129UTC , but now is AIR also up to S9+20db and DRM give very dropout. So I stop log her.

AF4MP
06-11-2010, 23:46
Software problems caused a decrease in time logged. Not bad reception 86.05% audio in nearly 3 hours

Here pretty much the same as yesterday but also interference during the last 30 minutes:

AF4MP
07-11-2010, 13:00
Very good until propagation closed the signal down half way through.

Brendan1
07-11-2010, 15:34
Some fading last night, some periods of it greater than others. It was still my best RNZI log last night.

Brendan1
08-11-2010, 12:31
Quite good, although it looks like some analog broadcasts may have been interfering badly.

As to who they are, I really don't feel like getting up at 0200 local time to find out. :rolleyes:

AF4MP
08-11-2010, 15:03
Propagation was up and down this morning, as a result only 37.89% audio.

Brendan1
09-11-2010, 12:25
Fairly mixed reception, definitely suffering from QRM I'd say.

AF4MP
09-11-2010, 15:16
Better this morning - 79.37% audio.

The strong adjacent analog signal at 9865 kHz, coming on at 11:30, certainly did not help!

This morning's reception report - 84.10% audio. The last half hour is down because of adjacent channel interference at 9865 kHz.

11-11-2010, 16:00
The best log for RNZI for me right now. This was really good! :)

Brendan1
12-11-2010, 14:06
Not quite as good as last night, overall it looks like the signal level was changed allowing the interference to do it's 'thing' better. :(

AF4MP
12-11-2010, 14:38
If it wasn't for the last half hour this report would have been nearly perfect!

AF4MP
13-11-2010, 12:14
