Hello friends,
Propagation during last weekend's broadcast Saturday at 1600-1630 UTC on 17860 kHz was probably the worst in the history of VOA Radiogram. The signal was generally unusable in Europe, and poor in most of North America. However, Loet in Curaçao had very good reception on 17860.
also had excellent reception using a receiver in Nova Scotia.
Let's hope for better conditions this weekend. The program will include an experiment with Russian text. The Cyrillic characters transmit at much slower speed than Latin characters: about 33 words per minute in MFSK32, and 70 wpm in MFSK64. We will try MFSK64 for the additional speed, but will this faster mode survive trans-Atlantic propagation?
For the correct display of the Russian characters, be sure to select the UTF-8 character set via Fldigi's Configure > Colors & Fonts
Here is the lineup for VOA Radiogram, program 107, 18-19 April 2015, all in MFSK32 except where noted:
1:23 Program preview
2:29 India's net neutrality debate*
7:76 US Congressional hearing on Russian international media
22:46 MFSK64: VOA Russian story about Yuri Gagarin*
26:53 MFSK32: Closing announcements*

AndFlmsg. If you have an Android phone or tablet, please try to decode VOA Radiogram using the beta AndFlmsg app, B0.5.0, which can be downloaded from http://www.w1hkj.com/vk2eta/ . This new version can decode MFSK images as well as text. AndFlmsg does not yet have the UTF-8 character set, so the Russian will not display.
Thank you for your reports on reception, or attempts of reception, from last weekend's program. The gallery of MFSK images will be interesting. I'll respond to your emails over the weekend.
