VOA Radiogram weekend schedule

Hello friends,

The German communications regulator Bundesnetzagentur jhas changed its mind about allowing digital modes on shortwave broadcast transmitters in Germany. Apparently BNetzA thought that Channel 292 was transmitting the text and images in single sideband (SSB), which is how amateurs, military, etc, transmit the digital modes. Now that they know that the MFSK32 and other modes are sent as program audio on an analogue amplitude-modulation shortwave transmitter, their objections were withdrawn.  (It's similar to A2A modulated CW.)

BNetzA prefers that the term MFSK32 not be used to describe these broadcasts, but we have to specify the mode so that you can set Fldigi or other decoding software to the correct mode. In any case, the weekly MFSK32 transmission will resume on The Mighty KBC, and DigiDX will return to Channel 292.

Meanwhile, VOA Radiogram this weekend will be all MFSK32 except for the transmission schedule in Olivia 64-2000 under the closing music.

Here is the lineup for VOA Radiogram, program 158, 9-10 April 2016, all in MFSK32 except where noted:

  1:32  Program preview
  2:46  China domain name rules*
11:58  South Korea blocks North Korea Tech website*
18:09  Mars Opportunity rover photographs dust devil*
23:01  Photo of migrant from RFE/RL Top Shots*
26:24  Closing announcements*
28:01  Olivia 64-2000: Frequencies under music

Thank you for your reports to VOA Radiogram last weekend.  I am now compiling the MFSK image gallery from program 136 (November 2015) and hope to send that out this weekend.

Fldigi saves decoded MFSK images as png files in the folder \fldigi.files\images\.  When you send a reception report, please attach those png files.

I hope you can tune in and write in this weekend.
