Rai / Radio Vatican on 26060 kHz

[maxpower]

Hi all!

Here's the first impression of Radio Vatican and Rai on 26060 kHz with the "HCJB-Pappradio".

Not much so see now, but I got up to the label. So reception is possible at Sporadic E conditions here in the north of germany. I'll try on. :)

Here is an image of my reception of 26060 khz, i live 500 meter from Vatican State..so it's no really a dx :-)

Took a chance and switched on the log in Dream this morning. Upon arrival back home my FRG-7700 hissed and showed signs of Es activity. The 20 kHz bandwidth is too much for my receiver, but I got about 20% CDA over 45 minutes. Nice to see and hear something new and different at last!

[iw0hk]

Hello,
i have recorded a 3 minutes 12 khz IF signal of the RadioVatican 26 mhz DRM emission in Rome here:

Some Es activity this afternoon towards the South of Europe. There was too heavy Fading to get any audio, just a few syllables around 1445 UTC. 0.22% CDA (!) and a maximum of 15.96 dB SNR at 1449 UTC. The log is 81 minutes long.

[petecchiaro]

Here is my reception.
I live in Rome about 8Km far from Vatican.
I receive the program using a SONY 7600GR modified for DRM and the original SONY wire antenna. Tuning is quite difficult due the 20kHz DRM bandwidth but once tuned the reception is quite good also inside the house.

The text message give information about the location of the trasmitter inside the Vatican

[PP5AZF-Ataliba]

Eu acho que a OFDM IF de transmissão DRM deveria ser utilizado 6000 Hz ao contrário de 5.000 Hz.
Em alguns testes que fiz micro-micro com SPARK IF 5.000 Hz foi mais fácil de decodificar o áudio. No DREAM, o DRM de 20 Khz será sintonizado entre 1 e 21 Khz ao contrário de 0 a 20 Khz.

Translation portuguese - english "Google"

I think IF OFDM transmission of DRM should be used 6000 Hz as opposed to 5,000 Hz.
In some tests I made with micro-micro SPARK IF 5,000 Hz was easier to decode the audio. In DREAM, the DRM of 20 kHz will be tuned between 1 and 21 kHz as opposed to 0 to 20 kHz.

[petecchiaro]

here is about one hour log in the evening captured in my house about 8km far form the trasmitter.
I use a SONY 7600GR modified for DRM and the original receiver's wire antenna.

[petecchiaro]

sorry error message

[petecchiaro]

today about 96% audio decoded in one hour indoor reception.

SONY 7600GR modified for DRM 8km from the Vatican

[petecchiaro]

this morning 99% audio decoded in one hour log.

Sony 7600GR modified for DRM, indoor wire antenna; urban area 8km from the Vatican

[petecchiaro]

Same good and stable reception as days before.
Same DRM receiver with indoor wire antenna.
Nice program from Vatican Radio

[petecchiaro]

today some changes in multiplex configuration: short interleaving.

99% audio decoded but probably the long interleaving is better for reception.

[petecchiaro]

this evening the field strength seems to be a little bit less and the audio decoded is only 95 %

[Digger]

Some traces of 26 MHz here this afternoon. Very little sound because of very deep Fading. SNR peaked at 19.4 dB at 1153 UTC.

[drmdab]

Wow, some DRM now on this frequency :) Please find a short log attached.

[FritzWue]

Unfortunately my SDR cannot set the filter wide enough, so no SDC data and no audio. :(

[Digger]

Same problem here.. No label despite sometimes a good SNR. Heavy Fading and lack of decoded audio made me cut the log short.

There is quite strong Es activity over Europe today.

[Digger]

Again 26060 with RAI Radiodue as the first label, Vatican as second, then celp and the fourth service was Journaline. Too much Fading to catch anything but the labels.

[mitajohn]

Hi all,

E-sporadic, a couple of minutes ago I received this...

[mitajohn]

Hi all,

The signal is still here (14:58) but my RX cannot cope with it.

[Digger]

Nice Sporadic E today, anyway it was possible to "see" 26060 for over an hour. The audio won't work, it comes through rather chopped. The audio pattern looks like mitajohn's here too.

[Digger]

Some sporadic E this morning towards the South.

[Digger]

And again this morning. The fade-outs were were rather log.

PS: Wrong antenna info in the plot; I used the gamma-match 25 MHz Dipole here.

[mitajohn]

Hi all,

I got again only the label of this TX.

[FritzWue]

I was lurking for Sao Paulo on 26040 kHz when I saw a panadapter signal on 26060 kHz.
It was in mode A/ 18 kHz.
The Power SDR software only allows max. 10 kHz bandwidth.
Maybe that was the reason why I could not decode the station's name.
The strange thing is that the station ID E24104 is different from E05202 reported before.
Later I tried the software in spectroscope mode and 48 kHz sampling rate, but then the signal was too weak for decoding.

[petecchiaro]

dear FrizWue yesterday at 15:24:20UTC at Vatican Radio I changed the transmission mode from A/10kHz to A/18kHz for test pourpose. However I can not explain the difference in the programme ID.

thank you!

[Digger]

I also saw the station ID E24104 today. There was no label (at least I did not get it) and the Mode A / 18 kHz did not produce any audio with Dream. The signal disappeared soon after I started the log.

... but came back after a while...

[simone]

Hi petecchiaro,
the service ID is correct for Vatican Radio, the other ID that Fritz was refering to was used for one of the other services some time ago (Radiodue).
Simone

[petecchiaro]

you are right Simone but I believed that the service ID was received these days (it is more than 1 year that Radiodue is out)

[drmdab]

Some signs from Vatican visible here, too, today. Nearly one year after I logged them first. :)
But no audio / label decode today.

[Digger]

A 34 minutes log with hick-hack sound because of the 18 kHz bandwidth. A text message:

"Questa trasmissione viene irradiata dalla trasmittente "Marconi" all'interno dei giardini vaticani sulla frequenza di 26060 kHz".

[FritzWue]

Some short skip propagation this morning.
I wonder which receiver has such a wide filter.

[simone]

I wonder which receiver has such a wide filter.

Hi Fritz,
I have not tried on this 18 kHz wide signal yet, but I never had problems to receive VTC´s 20 kHz wide signal from Crystal Palace with the winradio G313, see attachment.
I also modified my FRG-100 to work with 20 kHz bandwidth no problem.

Simone

Hi Simone,

oh yes, you are right!
I completely forgot that I still have my old G303i in some old P4 pc deep down in the cellar.
I really should reinstall it! :D

Thank you for that hint! :)

[simone]

I tuned in today, got some audio and also could decode journaline (seems to be from Easter).
Simone

[FritzWue]

Another opening this morning, I left early for 25740 kHz:

[MARCEL]

I receive at 10H05 to 12H50 UTC Vatican Radio of 26060 Khz many cut and later good audio, journaline, SNR / 5 to 13 db.
Curiouse is I receive only to DREAM no signal of DRM receiver Di-Wave 100.

I have problem for audio save with Dream, is possible or not possible !!!

A quick look at the Ionogramme from Rome showed strong Es activity, which resulted in quite a lot of audio from the Vatican for several hours. The first log was taken with the 455 IF filter installed and the second log with 100 pF instead of the filter. Still, what a weird configuration with 18 kHz BW and 23.44 kbps. :rolleyes:

Text message: "Questa trasmissione viene irradiata dalla trasmittente "Marconi" all'interno dei giardini vaticani sulla frequenza di 26060 kHz".

[Digger]

A 166 minutes log from this evening with 68 % CDA. The signal was strong enough to make my Morphy Richards utter a few words in the living room with the internal telescopic antenna.

Even the Journaline came up, but id did not last long enough to read the entries.

[simone]

I have problem for audio save with Dream, is possible or not possible !!!
...

Hi Marcel,
with Dream you can save the audio as a wav file, what´s the problem?
Simone

[MARCEL]

Hallo Simone,

Ist gut jetzt ich habe gefunden mein fehler, muss " .wav " nach dem Name machen Ok ist prima dass lauft.

[MARCEL]

Then 23.5.10 I receive many time to afternoon Vatican R. auf 26060 Khz many cut of audio no more signal at 18H25 :
13H35 UTC:
http://www.pictonale.net/2010/05/25/o51w74o/
17H04 UTC:

18H16 UTC:
http://www.pictonale.net/2010/05/25/5fr7x6k/

Yesterday 24.5.2010 I receive many time Vatican R. :
16H06 in French:

16H31:

18H41 UTC:
http://www.pictonale.net/2010/05/25/dvjwwws/

[Digger]

Around 1330 UTC the signal started getting stronger, but it suffered a lot from blackfoot CB "communication" in the beginning. The signal peaked around +30 dB uV at times.

[stef]

reception this evening first time for me,1155km distance with i think 200watt of power and some audio glitches.
When the sun goes to its maximum sunspot there will be big problems on the 26 mhz band.

[Digger]

I looked at the Rome Ionogram and saw strong sporadic E there so I switched to 26060. The result is a 76 minutes long log, but oh my **d, what horrible sound !!! The audio was unrecognizable under a horrific 100 Hz hum. Just for fun I took the Morphy outside on the table and suffered the same horrible hum there too. Something wrong there, somewhere. I took some pictures and a video if someone is interested.

[Digger]

There was strong sporadic E on the Rome ionogram this morning. The horrible audio (mostly 100 Hz hum) is still on. Nobody cares at all? :confused:


I added the RealAudio File as .txt, rename it and enjoy.

[stef]

it is the same with air,it seems that nobody listens.

[Digger]

Just now at 0915 UTC I "hear" (?) 26060 with 99.8 % horrible hum and 0.2% audio, roughly to that ratio. Don't they ever monitor what they put into the air?

A short log - it is not worth listening to... :eek:

[FritzWue]

I did not yet install the radio with wider filter:

[Digger]

71 minutes of the interval signal "Christus Vincit", somewhat boring after a while, but no irritating hum this afternoon. :rolleyes:

[Digger]

Double that from my last log, 141 minutes log without much sporadic E judging from the ionogrammes from Rome, Juliusruh and Praha. About 65 % decoded audio for the whole log, 97% CDA for 41 minutes between 1525 and 1605 UTC. Surprisingly good reception for a swl. Perhaps I should have set the AGC to "fast" from the very beginning.

PS: The hum is gone.

[Digger]

Strong Sporadic E was present in the ionogramme in Rome this morning. Rather "solid E" instead of "Sporadic" :)

26060 was already playing when I started the log. The conditions lasted for 4 hours and 53 minutes, and the decoded audio was >90%. :cool:

[FritzWue]

Acc. to the ID it was Radio Vatican.
Now a russian FM relay on 26054.5 kHz is coming through. :mad:
