After the noise begins, a VOA News story in MFSK16 will first be transmitted at full level, then reduced to -6 dB, then reduced to -12 dB. I will probably lose many of you when the level is reduced to -12 dB, but please stay tuned: the audio level will soon be restored.<\/p>\n<p>Here is the lineup for VOA Radiogram, 15 and 16 June 2013:<\/p>\n<ul>\n<li>2:10 MFSK16: Program preview<\/li>\n<li>1:58 MFSK16: Introduction to noise experiment<\/li>\n<li>10:09 MFSK16: At -0 -6 -12 dB versus noise<\/li>\n<li>:59 MFSK16: Image of VOA logo<\/li>\n<li>:47 MFSK16: Introduction to MFSK32<\/li>\n<li>:51 MFSK32: Image of VOA logo<\/li>\n<li>3:19 MFSK32: VOA News re Curiosity Rover on Mars\u00a0MFSK32: VOA Radiogram logo<\/li>\n<li>2:40 EasyPal Image of the week<\/li>\n<li>1:10 MFSK16: Closing announcements<\/li>\n<li>:20 Surprise mode of the week<\/li>\n<\/ul>\n<p>VOA Radiogram transmission schedule<\/p>\n<p>(all days and times UTC)<br \/>\nSat 1600-1630 17860 kHz<br \/>\nSun 0230-0300 5745 kHz<br \/>\nSun 1300-1330 6095 kHz<br \/>\nSun 1930-2000 15670 kHz<\/p>\n<p>All via the Edward R.
