VOA Radiogram this weekend

 VOA Radiogram is a Voice of America program experimenting with
digital text and images via shortwave broadcasting.

 VOA Radiogram will 'soft launch' this weekend, March 16/17. Here is
the transmission schedule (all days and times are UTC):

     Saturday 1600-1630 17860 kHz
     Sunday 0230-0300 5745 kHz (Saturday evening in North America)
     Sunday 1300-1330 6095 kHz
     Sunday 1930-2000 15670 kHz

 All via the IBB Edward R Murrow Transmitting Station in North Carolina.

 The digital text modes to be transmitted this weekend on VOA
Radiogram are as follows. Each text transmission will be one minute,
unless otherwise specified. Asterisk * denotes RSID: if your RxID is
on, Fldigi will automatically switch to this mode and audio frequency.
The other modes you can decode from your recording.
     BPSK31 on 2000 Hz*
     QPSK31 on 1000Hz, BPSK31* on 2000 Hz
     QPSK31 on 1000Hz*, PSK63F on 1500Hz, BPSK31 on 2000 Hz
     QPSK63 on 1000 Hz, PSKR125 on 1500 Hz*, BPSK63 on 2000 Hz
     QPSK125 on 1000Hz, PSKR250 on 1500 Hz*, BPSK63 on 2000 Hz
     QPSK250 on 800 Hz, PSKR500 on 1500Hz*, BPSK250 on 2200Hz
     QPSK500 on 800 Hz, PSKR1000 on 1500 Hz*, BPSK500 on 2200 Hz
     PSKR500 on 1000 Hz, PSK63F on 1500 Hz, PSKR125 on 2000 Hz, and
PSKR250 on 2500 Hz* (5 min 40 secs).
     MFSK32 image on 1500 Hz (54 seconds)

 The latter portions of the PSKR250 and 500 transmissions are
formatted for Flmsg. (In Fldigi, Configure > Misc > NBEMS > under
Reception of flmsg files, click Open with flmsg and Open in browser,
and below that state the location of the flmsg.exe file.)

 In future weeks, after the “hard launch” of VOA Radiogram, only one
mode will be transmitted at one time. This will ensure the highest
possible signal-to-noise ratio and the best possible chances for a
successful decode.
