DRM tests from FEBC Saipan
Starting on 4/15/09 FEBC, Saipan hopes to be testing DRM on 11650 KHz at 0900 to 1000 UT. Beaming 341 degrees, (Japan, Korea, Russia, and Northern Europe) Daylight absorption will limit signals west of middle Russia, but any reports from anywhere are welcome. This is early evening Japan time. Thanks for any and all reports, via this forum and to kfbseng@febc.org. We have permission to test for three weeks. Signals may not be on every night, but we hope to be on at least 10 or more nights. Later tests to be announced towards China.

All the equipment seems to be working well. We should be on as scheduled. Various modes will be tried. Thanks to all who listen and pass on the word.

Signal is coming through!
 But there is AM on 11645 kHz, so too much interference for decoding audio at my location in northwestern Germany.

FEBC Saipan on 11650
Thanks for encouraging first reports. Based on request from Japan we will run Parametric Stereo tomorrow night. For FritzWue, we could try a brief test using 4.5 KHz mode on USB, if we know you are there. LSB is interfered with as your plots clearly show. Many thanks to all.

In the middle of Russia in Irkutsk I receive the signal by telescopic whip by
Hyundai 1613+ heterodine 465KHz with not bad sound quality. Tomorrow I'll try to do the DRMcalc Last edited by Siber : 15-04-2009 at 11:22. |

Parabéns pelos testes da rádio FEBC Saipan.
Gostaria de sugerir que façam testes em Parametric Stereo, modo A, 18 kbps. Estas configurações são utilizadas pela rádio CVC 17.640 Khz e resultaram em excelentes qualidade de áudio estéreo e de decodificação de sinal. Eu acredito que poderão obter maiores informações diretamente com o engenheiro Mathias Svensson <mathias@cvclavoz.cl> Translation portuguese > english: "google" Congratulations for testing of radio FEBC Saipan.
