VOA Radiogram is a Voice of America program experimenting with digital text and images via shortwave broadcasting. It is produced and presented by Dr. Kim Andrew Elliott.
During the weekend of 23-24 November 2013, VOA Radiogram listeners have been receiving badly slanted MFSK images. The problem is somewhere at the transmission end.
This weekend, to receive unslanted images, use this Fldigi setting:
Configure > Sound Card > Settings > Corrections > RX ppm set to -2250
You might have to adjust that RX ppm a bit for your PC and sound card.
If you want to decode from the “studio” recording of this weekend’s broadcast:
soundcloud.com/voaradiogram/voar34
But set the RX ppm back to 0 (zero), because the recording seems to be OK.
Remaining broadcasts today, Sunday, 24 November:
1300-1330 UTC on 6095 kHz
1930-2000 UTC on 15670 kHz
