Hi,

Very good reception. The two interruptions were A) my tuning the RX and B) a sudden TX break about 40 seconds or so.

Terje

PS: Carsten, the carrier disappeared for about 40 sec, - S0. That's why.

carknue

15-03-2006, 20:08

Perfect, but again one strange drop....:confused:

carknue

16-03-2006, 19:28

Wow, no drop today.

CT4RK

17-03-2006, 08:48

Hi Carsten
The dropouts was caused by the antenna change, due the works on 4MHz antenna that is near of the TCA3 (normaly runing the 13810).

simone

17-03-2006, 09:27

Hi all,
strong and stable signal, but a few dropouts at the beginning, using DWT/LA380 indoors

Hi Simone and all,

I think, that I had the same drops at the beginning.

Hi all,

super strong signal!!!! Receiver seems to be overloaded - low SNR, above 90 dbµV even audio decoding stoped! At 8:30 I switched on a 20 db attenuator.

Hi all,
also very strong signal here this morning.

df9rb

19-03-2006, 09:05

Hi all,

very strong again. With no attenuation (befor 8:15) low SNR and drop outs. During the last 30 minutes I played around with manual gain or different attenuations (20, 30 or 40 dB).

Bernd, DF9RB

Hi all,

My first report on this frequency. A bit late start of the log but a pretty good result.

John.

df9rb

24-03-2006, 09:04

Strong and stable, TS850 with 20 dB att., the DRT1 has no problems with signals above 90 dBµV.

Bernd, DF9RB

hi all,
13810 is too nosey my place.
noise level was S- 7.5 at my place.
I guess Only my place was bad SNR in Japan.

Hi All

Quite good reception for most of today's broadcast on 13810 kHz.

Cheers, Chris

Digger

05-04-2006, 15:01

Hi,

Quite good reception this morning, although the Antenna DX / LOC was in the LOC position, which attenuated the signal 27 dB... The first time ever I managed to get >34 dB SNR :)

Terje

Digger

06-04-2006, 12:04

Hi,

Tried some different settings, but overall there was more Fading today. Yesterday was almost a bit better.

Terje

Digger

08-04-2006, 12:58

Hi,

Perfect!
But at times >20 dB fading.
But perfect...

Terje

Digger

09-04-2006, 10:29

Hi,

Near perfect. A bit of Fading but not so deep as yesterday.

Yes, very good.

Terje

Digger

27-04-2006, 09:12

Hi,

DRM: Perfect. However, I thought I heard several dropouts in the audio, but there are no traces of this in the log :confused:

Terje

CT4RK

01-05-2006, 21:45

Hi Digger

These dropouts were caused by trouble in our MDI encoder.

Hi,

49 min report from Helsinki. stable and strong signal,

Hi all,

this frequency is strong and stable in Helsinki. 54 minutes 100%

...Seppo

Digger

05-05-2006, 09:14

Hi,

This frequency is very stable in Switzerland too.

Terje

Digger

06-05-2006, 09:10

Hi,

I was not in, so I started Dream with the Timer Function. I was not aware of the quick AGC setting at the time. When I came back in I switched to my special Slow AGC and the difference in SNR is striking. What was the break around 0855 UT?

Very stable reception on this frequency.

Terje

Mitsuru Ito

07-05-2006, 09:15

hi all,
21820KHZ was very noisy today.
So I received this frequency instead of 21820KHz.
But this frequency was better thank 21820KHZ.

Digger

09-05-2006, 11:16

Hi,

Good as usual. High SNR (as usual).

Terje

Mitsuru Ito

11-05-2006, 09:25

hi all,
It was not so good today
the signal came with QSB.

Hi,

54 minutes of DW. Time: 08:04 - 08:58 UTC.
Result: 90% CDA.

Digger

16-05-2006, 11:38

Hi all,

Short, but perfect. Rumours about Sporadic E made me stop logging and QSY.

Terje

Digger

17-05-2006, 09:13

Hi all,

Much better is almost not possible. The dip in the SNR was caused by increasing the input AF level to the sound card - :o

Terje

Mitsuru Ito

18-05-2006, 09:10

Hi all,
This frequency wasbetter than DW from tricomalee-
on 21820KHZ.
I gave up to reaice 21820KHZ at 08:35.

20-05-2006, 13:08

A bit weak this morning, but perfect.

Digger

20-05-2006, 16:46

Hi,

Yes, the signal was a bit on the weak side here too... But good anyway.

Terje

21-05-2006, 14:24

Hi all.

32min. of solid reception from DW to close down.

Hi all

The azimut from Sines are....( see map attachment )

Digger

02-06-2006, 10:29

Hi,

The antenna switch at 0830 is seen in the log. The signal strength in Switzerland is not much affected. High SNR as usual from Sines. Compliments to the equipment ant the people behind the knobs and switches!

Terje

PS: Instead of the VFO, I used an external crystal oscillator.

mitajohn

03-06-2006, 14:12

Hi all,

Here is a very good result on this TX. At 13H57 an English spoken "super" carrier appeared on channel killing DRM and I stopped the log. See the files.

John.

Digger

05-06-2006, 14:46

Hi,

Today the reception was much more "bumpy" with the SNR History looking like the edge of a hack-saw blade. No records today :(

Terje

Digger

06-06-2006, 15:20

Hi,

The conditions were not the best, but the reception was very good.

Terje

mitajohn

07-06-2006, 14:00

Hi all,

Here is a good result on this TX but not the best.

John.

Digger

07-06-2006, 14:14

Hi,

The first 30 minutes were best.

08-06-2006, 14:00

Hi all,

A nearly excellent result today.

Hi,

Quite good, but I've seen even better.

Terje

11-06-2006, 14:26

Hi all,

There are even better results than this one.

John.

13-06-2006, 13:07

Hi,

Just 30 minutes, but almost perfect.

Terje

Digger

14-06-2006, 09:26

Hi,

A bit longer log this morning. Some TX-related problems around 0620 UTC with loss of audio and sync. I thought the signal faded out for a while before 09 UT, but it recovered later.

Terje

mitajohn

17-06-2006, 12:07

Hi all,

Too much signal level fluctuations today, over 35dB on the meter's scale, though a very good result.

John.

Digger

19-06-2006, 12:49

Hi,

A three hour log from this morning. Very good as usual.

Terje

mitajohn

19-06-2006, 14:07

Hi all,

A very unstable signal led to a bumpy reception and result. I can't tell anything for the big dropouts, are they TX switchings or break downs, since the log was unattended.

John.

Digger

20-06-2006, 11:49

Hi,

A two hour log from this morning. About 0915 UT the SNR decreased suddenly. I had no 2nd receiver to check what was going on. After 15 minutes the SNR recovered.

Terje

mitajohn

24-06-2006, 09:31

Hi all,

Almost one hour of excellent results. The dropout was at the br switching.

John.

Hi all,

It would be better.

John.

mitajohn

02-07-2006, 14:01

Hi all,

Problematic transmission today, all dropouts are rather TX related.

John.

Digger

02-07-2006, 16:01

Hi,

And here is the part from the start up till the start of Mitajohn's log. The two breaks are TX-related. Perfect reception.

Terje

04-07-2006, 15:55

Hi,

Except for "something" that I missed when it happened around 09 UTC, the rest is almost perfect.

Terje

Hi all,

A weak signal but a very good result.

John.

mitajohn

06-07-2006, 13:59

Hi all,

An average signal but a nearly excellent result.

John.

Digger

06-07-2006, 15:02

Hi,

An M2.5 flare made the DW to fade out completely around 0830 UTC. Unaware of this at the time, I decided to stop logging.

Terje

Digger

07-07-2006, 10:04

Not as good as usual. Maybe it is the aftermath from yesterday?

Terje

mitajohn

07-07-2006, 14:00

Hi all,

A mostly weak signal. A good result from 12H00 - 13H45.

Hallo,
I use an ELAD FDM77DRM Receiver with the same software. With my variante of doubble zeppelin (2x18,50m with 25m symetric line 250 ohm) I have SNR Rapport 26 to 31 db and over an 11 m long-wire 22 to 25dB. I receive daily the transmission DW from Portugal and the values are everytime excellent over all frequencies. With my receiver I have the possibility to use also ELAD SOFTWARE FDM77 STANDARD (45 euro), a light version from official DRM software without location and other features. The greatest errors making by listeners is a bad location to install the antenna. Last june I have speak with an ingenior from BCE, fialiale from RTL Group and we have the same results.

mitajohn

07-07-2006, 19:18

Hi François and all,

The best results I have gotten here are when transmissions are beamed to SE Europe as seen in my posts, on other frequencies. This frequency does not received enough well but sometimes it does.

John.

Digger

10-07-2006, 11:29

Very good reception here 0800-0930 UTC.

Terje

Digger

11-07-2006, 10:07

Despite the bad reception on 6 - 7 MHz earlier this morning, here are two perfect hours from DW.

Terje

Digger

13-07-2006, 12:19

Perfect - as usual.

Terje

CT4RK

16-07-2006, 09:00

Hi all
Yesturday, we have update some software in the SRATUS and the TX seem to be more "overcharged" with this software due the lot of trips that ocurre during the transmission. I have tryed retune all tuning elements, but without any results. Also with this software, under trip conditions, the encoder, lost synchronism and need about 1 mn to restart the normal conditions. So, all dropouts that you can see when the reception conditions are good, probably are from trips of the TX.

Today's result of the first hour of the transmission.

Terje

FritzWue

01-09-2006, 14:36

SNR Maximum [dB]: 40.8 :D
The impulse response looks like a needle! :)
When I checked the frequency after sign off the reason for the unsteady SNR plot were splatter from China Radio on 13790 kHz. :mad:
Their AM modulation is at least 15kHz wide and overmodulated. :mad:

Digger

01-09-2006, 16:23

Hi,

13.81 MHz is my favourite as well. Here are the two first hours. Very good overall.

Terje

Digger

02-09-2006, 15:50

Hi,

Just look at this. Like a dream (hi). But the first 30 minutes were not so fantastic in respect to signal strength. However, today I broke my personal SNR record with 0.1 dB to 38.6 dB. :) but the Impulse Response was not like a spike but more like the tip of a snake's tounge.

Terje

FritzWue

02-09-2006, 16:14

SNR Maximum [dB] 40.8 :D
I wonder if that is the TX limit. :rolleyes:

mitajohn

03-09-2006, 08:59

Hi all,

This TX has no good footage here. Today the signal was up to 45dBuV for about half an hour. Then a TX break down occoured and when TX came back the signal was hardly 30dBuV and decoding problems started.

John.

Digger

03-09-2006, 15:58

Hi,

A bit messier conditions today I thought, but that did not prevent a new personal SNR record: 38.8 dB. The entire log is enclosed.

Terje

Digger

04-09-2006, 14:23

Hi,

A slightly shorter log today due to an other application running on my computer. The interruption happened during my lunch break - no idea what it was. Otherwise stable reception as usual.

Terje

Digger

05-09-2006, 15:13

Hi,

Today's log. Very good and stable.

Digger

06-09-2006, 14:08

Hi,

I used the Ferrite Antenna for 17 MHz for the first 45 minutes, but the signal was not so strong, so I changed to the Long Wire. Therefore, there are two logs. I wonder if the American Preacher Man on 13.810 MHz starts *at* or *before* 1400 UTC ??? :confused:

Terje

Hi,
strong also in Helsinki, max SNR 37.6 dB.
Seppo

Digger

07-09-2006, 14:23

Hi,

Was it solar activity that caused a shaky start? Something triggered something at or about 0830 UTC (see the JPG file shot at the beginning of the transmission). Or does Iran continue to transmit in AM in Arabic (?) on 13810 even after 08 UTC? Later it improved and the SNR ratio got better and better.

Terje

Sixten

07-09-2006, 18:47

Hi all.

Very strong signal today .Only slow QSB S9+20db to S9+40db.

Digger

08-09-2006, 14:05

Hi,

A shorter log today, but close to perfect. Much closer would be difficult. :)

Terje

FritzWue

08-09-2006, 18:35

..not too difficult! :)
SNR Maximum [dB]: 40.5
CDA [%]: 100.00 :cool:

Digger

08-09-2006, 19:26

2 dB loss across the Schengen border......:D

hsseppo

09-09-2006, 14:10

Hi,
5 dB less in Helsinki...
Seppo

Andreas

09-09-2006, 15:05

..and 5 dB less in Hamburg either.

Also less stable reception at me. While SNR of 35.6 dB is a new personal all-time high for me :cool: there were some bad phases.
When watching these I could see signal becoming quite weak and IR changing from one (strong) pulse to two (much weaker) pulses. So I guess I encountered once more a pothole in the ionosphere rather than local disturbance being the reason.

FritzWue

09-09-2006, 15:24

SNR Maximum [dB]: 42.0 (EU bonus) :D
For me also a new all time high. :cool:
Conditions were indeed very unstable, my SNR graph is between 29 and 42 dB.

Digger

09-09-2006, 16:08

Hi,

The SNR varied between 21.3 and 38.1 here today. 100% CDA. Very good.

Terje

Andreas

09-09-2006, 17:21

Risking to become OT now - Maybe this explains the 5-7 dB less:

Digger

10-09-2006, 12:57

Hi,

If you would cut out the break for the antenna switching at 0829 UTC, then the CDA would become 100%. A new personal SNR record today : 39.0 dB :)

Terje

FritzWue

10-09-2006, 14:32

I also did some antenna tests at the beginning and found that the signal is more constant if I only use the northern leg of my dipole antenna in L-configuration.
Two logs today with a formula 1 race in between. ;)
After the antenna tests both logs show the same max. 41.6 dB SNR and 100% CDA. :)

FritzWue

11-09-2006, 15:26

SNR Maximum [dN]: 41.2
CDA [%]: 100.00

Digger

11-09-2006, 15:57

Hi,

A rather shaky start this morning before the break at 0828 UTC. The rest was very good.

Terje

FritzWue

12-09-2006, 14:10

SNR Maximum [dB]: 41.5 :)
with a break at 10:00 UTC:

Digger

12-09-2006, 14:25

Hi,

Not so good today. Three extra breaks unaccounted for - two might have been lightning from a thunderstorm in the vicinity. :confused: The 4th one at 0959 UT was a longer one and definitely TX-related.

Terje

FritzWue

13-09-2006, 15:39

First log: From A30 near Herford to Minden
Second log: From Minden to A30 near Osnabrueck
Big dropouts in the Weserauentunnel between Minden and Bad Oeynhausen.

First half of first log and second half of second log were at high autobahn speed. SNR drops about 4dB then.
I think this is not only caused by higher noise from the car but also because the top end of the antenna bends down with the wind so that it points horizontally.

Digger

13-09-2006, 18:59

Hi,

Today's log looks normal to me. Looks very good too. The break at 10 UT came today too.

Terje

mitajohn

14-09-2006, 13:04

Hi all,

A weak signal [below 30dBuV] gave the attached result for about 30 mins then gone away...

John.

Digger

14-09-2006, 14:00

Hi,

Absolutely no problems in Switzerland. There was a bit of splatter from 13.800 MHz just at the end of DW's transmission, otherwise the channel was clear until 1356 UT when the next user powered up.

A weak signal mostly below 32dBuV (~S8), very close to the decoding threshold, gave the attached (not good) result until it disappeared.

Hi all and Terje,

Do not touch Dream while logging. You get these high values when you move or resize a Dream Window. I believe it's a problem of the Qt GUI.

Hi,

Just before 8 UTC there was an AM carrier on the channel. Sounded the same as the station 10 kHz down, something in Arabic (?) but more distorted. There were a couple of TX breaks and it was possible to hear the AM station then.

The reception was even better in the afternoon.

At the start there was not much signal at all. There were intermittent "showers" of RF signal, but after a while the S-meter rose from a shaky S2-S3 to S9 +20 dB, which is more like normal.

I think there were several problems this morning. First DW had problems starting up the transmitter and then the peculiar ionospheric conditions, which still prevail now at 1150 UTC. I left 13.810 after a short while.

Usually very good, but today DW suffered from splatter from 10 kHz down - badly or overmodulated AM. This caused the SNR to vary from 38 dB at its best down to 20 dB.
