Hello friends, Last weekend, Radio Habana Cuba had a special transmission on 17580 kHz,creating an interesting co-channel situation with VOA Radiogram Saturday at 1600-1630. RHC caused only minor interference in Europe, but in parts of the Americas, decoding VOA Radiogram was difficult. In this video by Tim in Colorado, VOA Radiogram and RHC are fairly evenly matched
http://voaradiogram.net/post/142916923957/voa-radiogram-prevails-with-radio-habana-cuba Last weekends Olivia 64-2000 provided some good decodes despite poor reception conditions. Here is an example from a receiver in Sydney, NSW, Australia http://voaradiogram.net/post/142890107842/voa-radiogram-16-april-2016-0930-1000-utc-5745 On the other hand, some listeners were not as successful with Olivia 64-2000, and found that this mode did not perform as well as MFSK32 which is much faster. I wonder if the problem is related to the receivers bandwidth. Olivia 64-2000 extends to 2500 Hz above and below the carrier. If any of that data is clipped, the decode might be less than 100%. We could try some experiments with this in future programs. This weekend, all the content will be in MFSK32, except for the transmission schedule in Olivia 64-2000 mixed with the closing music. Here is the lineup for VOA Radiogram, program 160, 23-24 April 2016, all in MFSK32 except where noted: 1:34 Program preview 2:44 Can AC and DC power integrate?* 12:13 Radio Farda TV signal jammed in Iran* 16:38 New report finds media freedom declined globally* 26:53 Closing announcements* 28:17 Olivia 64-2000: Frequency schedule under music * with image Please send reception reports to radiog...@voanews.com.
