Hi Simone (and Jacques),

I'll certainly be trying here! I think it should be quite good, as I am more or less in line with the beam.

This transmission is a little late for europe! :rolleyes: :D
P.S.: I detected 17545.25 kHz as center frequency. :confused:

Hi All

TDF 17545 kHz received here in New Zealand today. Signal gradually improving until
logging ended by my laptop battery going flat :mad:

My log looks quite good until the last hour when the band quickly fell apart. A nice flat line to the SNR. :D

Good to hear Montsinery on the air in DRM once again. They always do a fine job of covering the continent here. Thanks to all!

Well, I had the band fade out on me briefly, but the day ended very well all told.

The statistics for today still beat out yesterday's numbers.

Only managed to catch the last 20 minutes of today's broadcast, so I don't know what the signal was like earlier. Some decoding was possible.

Yesterday was terrible reception here - no audio at all.

Cheers, Chris

Well, something happened today - I don't know what, but my log isn't very good. It looks like the transmitter may have had problems, but only TDF knows for sure. It would also appear that the band faded out again.

Very good for five minutes, then the signal quality got worse although the strength was still the same:

Well, reception was excellent until around 2300 when the band obviously began to fall apart.

For the last day of the Las Vegas (Lost Wages) special broadcast, everything went very well up until 2257 when it looks like the transmitter went off the air.

I have one graph that shows only the time I had a DRM signal to log. While I was in the far-off rural areas of my county working, my faithful PC took copious notes in my absence. :)
