NETHERLANDS ANTILLES 15745 at 1300- UT, The Disco Palace, on Mar 8.<br />

Test transmission scheduled 1300-1825 UT. Carrier on at 1259:50 UT. cut<br />

straight into already started Leo Sayer song then cut off before finish to<br />

ID 'Feel the music - the Disco Palace'. Other IDs given say station name<br />

first. DRM ID The Disco Palace'. DRM Mo<strong>de</strong> B. SNR 19.5dB 20.96kbps stereo.<br />

Drop outs as SNR drops more frequent than from Issoudun. After 1400 UT<br />

// 6015 kHz.<br />

Disco Palace currently on 15760 kHz in AM (not DRM). Thanks to Steve<br />

Calver on BDXC-UK yg for tip. SIO 252 at 1631 UT tune-in. Break in music<br />

but carrier still on with buzz 1637-1654 UT. Disco music back 1654 and<br />

jingle and ID at 1701 UT then more cont. music.<br />

(Alan Pennington-UK, BrDXC-UK ng / dxld March 8)<br />

There were a couple of reasons for this DRM test.<br />

1. For the first t<strong>im</strong>e we tested the complete audio transmission chain<br />

<strong>de</strong>veloped for DRM. Which means a DRM content server in the studio and a<br />

MDI stream via IP into the DRM modulator of the Thomson transmitters in<br />

Bonaire. In the case of Bonaire this has not been tested before and TDP<br />

was able to set up this MDI stream for RNW.<br />

2. RNW choose to transmit to Europe during office hours between 1300-1830<br />

UTC. This way we could analyse the MDI stream and overall performance of<br />

the DRM signal during a long period.<br />

3. In principle the analogue transmission next to the DRM signal had<br />

nothing to do with the DRM transmission. However, this was necessary to<br />

test the power generators on full load after maintenance. The 3rd TX was<br />

"on air" on the dummy load.<br />

(Rocus <strong>de</strong> Joo<strong>de</strong>-HOL, RNW, via Andy Sennitt, March 10/11, dxld)<br />

As I said before, I can't <strong>im</strong>agine the big signal on 17840 being only<br />

to a dummy load, unless that ordinarily allows plenty of kW to leak<br />

into the real antenna, anyway. Maybe it really was from some other<br />

site? (Glenn Hauser, OK, DX LISTENING DIGEST)<br />

Das war eine Eintagsfliege. Aauch // auf 6015 Issoudun in DRM, welches<br />

Steckenpferd Ludo Maes schon einige Jahre reitet - und in Darwin ritt.<br />

Vom Jean Gilbert <strong>de</strong>m WRTH Redakteur:<br />

6015 1400-, The Disco Palace, Mar 8. Carrier on at 1400:41 secs, straight<br />

into already playing pop song - // 15745 kHz. DRM mo<strong>de</strong> B, SNR 22.1dB. DRM<br />

ID: 'The Disco Palace'.<br />

und auch einige Minuten in AM auf <strong>de</strong>m dritten Sen<strong>de</strong>r in Bonaire auf 17840<br />

kHz.<br />

Laut <strong>de</strong>m Techniker Jan Peter Werkman:<br />

" Than a few minutes later we also tried 17840 kHz on 50 <strong>de</strong>grees in AM on<br />

the 3rd transmitter to compare propagation between 15760 and 17840 kHz.<br />

But this test only lasted a few minutes as the SWR was not good so we<br />

<strong>de</strong>ci<strong>de</strong>d to shut down that transmission. This all at about 1300 UT."<br />

...danke in die gesamte Run<strong>de</strong> fuer diesen Tip! Hier 24 dB, 18,44 kbps,<br />
