NETHERLANDS ANTILLES 15745 at 1300- UT, The Disco Palace, on Mar 8.
Test transmission scheduled 1300-1825 UT. Carrier on at 1259:50 UT. cut
straight into already started Leo Sayer song then cut off before finish to
ID 'Feel the music - the Disco Palace'. Other IDs given say station name
first. DRM ID The Disco Palace'. DRM Mode B. SNR 19.5dB 20.96kbps stereo.
Drop outs as SNR drops more frequent than from Issoudun. After 1400 UT
// 6015 kHz.
(Sean Gilbert-UK, International Editor-WRTH, Web:
Disco Palace currently on 15760 kHz in AM (not DRM). Thanks to Steve
Calver on BDXC-UK yg for tip. SIO 252 at 1631 UT tune-in. Break in music
but carrier still on with buzz 1637-1654 UT. Disco music back 1654 and
jingle and ID at 1701 UT then more cont. music.
(Alan Pennington-UK, BrDXC-UK ng / dxld March 8)
There were a couple of reasons for this DRM test.
1. For the first time we tested the complete audio transmission chain
developed for DRM. Which means a DRM content server in the studio and a
MDI stream via IP into the DRM modulator of the Thomson transmitters in
Bonaire. In the case of Bonaire this has not been tested before and TDP
was able to set up this MDI stream for RNW.
2. RNW choose to transmit to Europe during office hours between 1300-1830
UTC. This way we could analyse the MDI stream and overall performance of
the DRM signal during a long period.
3. In principle the analogue transmission next to the DRM signal had
nothing to do with the DRM transmission. However, this was necessary to
test the power generators on full load after maintenance. The 3rd TX was
"on air" on the dummy load.
(Rocus de Joode-HOL, RNW, via Andy Sennitt, March 10/11, dxld)
As I said before, I can't imagine the big signal on 17840 being only
to a dummy load, unless that ordinarily allows plenty of kW to leak
into the real antenna, anyway. Maybe it really was from some other
site? (Glenn Hauser, OK, DX LISTENING DIGEST)
Das war eine Eintagsfliege. Aauch // auf 6015 Issoudun in DRM, welches
Steckenpferd Ludo Maes schon einige Jahre reitet - und in Darwin ritt.
Vom Jean Gilbert dem WRTH Redakteur:
6015 1400-, The Disco Palace, Mar 8. Carrier on at 1400:41 secs, straight
into already playing pop song - // 15745 kHz. DRM mode B, SNR 22.1dB. DRM
ID: 'The Disco Palace'.
und auch einige Minuten in AM auf dem dritten Sender in Bonaire auf 17840
kHz.
Laut dem Techniker Jan Peter Werkman:
" Than a few minutes later we also tried 17840 kHz on 50 degrees in AM on
the 3rd transmitter to compare propagation between 15760 and 17840 kHz.
But this test only lasted a few minutes as the SWR was not good so we
decided to shut down that transmission. This all at about 1300 UT."
