[DX] VOA Radiogram this very last weekend of August

[Kari Kallio <kari.kallio@xxxxxxxx>]

Hello friends,

This weekendâs VOA Radiogram will include an experiment suggested by Mark
Hirst in the UK. Mark notices that interference to MFSK images comes from RF
noise that is concentrated in the lower audio frequencies. He wants to know if
images might be clearer if they are transmitted at a higher audio frequency.

Because of a few extra minutes in this weekendâs program, the third image will
be transmitted a second time, at a center frequency of 2000 Hz.

Here is the lineup for VOA Radiogram, program 126, 29-30 August 2015, all in
MFSK32 except where noted:

1:30 Program preview
2:45 Strife reduces pollution in parts of Middle East*
9:03 Diminished marine biodiversity*
16:10 Plastic debris in the Pacific Ocean*
24:18 MFSK32 at 2000 Hz: Same image*
26:37 MFSK32 at 1500 Hz: Closing announcements*
