From Kim Andrew Elliott:
Hello friends,
I forgot to mention last week that for listeners in most of North America, VOA Radiogram is now on one hour earlier
by local time, now that Daylight time has reverted to Standard time. The UTC times are the same.
Last week’s
broadcast Sunday at 1930-2000 UTC on 15670 kHz was again inaudible in
Europe. But, again, it provided good text and images to the western USA.
Possible solutions to the poor 15670 kHz would be a change to a 13 or maybe 11 MHz frequency at the same 1930 UTC time.
Or a change of broadcast time to dawn in Europe, around 0500 or 0600 UTC, probably on a frequency near 6 MHz.
I am also
considering a change the Sunday 0230-0300 UTC frequency to dusk in North
Carolina, around 2300 UTC, for maximum night-time propagation to the
east.
Please let me know if you have any thoughts about changing VOA Radiogram times and frequencies.
This weekend, we will try an experiment suggested by Roger in Germany.
As you know, the
transmitter hum, most pronounced at 360 Hz, has mixed with the RSID,
resulting in the Fldigi RxID flipping the audio frequency to ~1140 Hz
rather than the correct ~1500 Hz.
Roger suggested
transmitting “nonsense data” at 360 Hz, in addition to the primary data
at 1500 Hz, to see if it prevents the intermodulation that causes the
incorrect audio frequency. Or maybe it will make
it worse. In any case, this should be fun.
Please follow this procedure for this weekend’s VOA Radiogram:
1.
Configure > IDs > ID > RsID >
select Searches passband
2.
At 1:45 into the
show, observe if RxID changes center frequency to 1140 Hz rather than
the correct 1500 Hz. Change it back to 1500 Hz if necessary
3.
At 2:30, during the
program preview, BPSK63F (PSK63F) at 360 Hz, reduced by 15 dB, no RSID,
with the VOA Radiogram transmission schedule, will begin.
4.
At 2:56, the mode
changes to Olivia 64-2000, with RSID. Observe if the audio frequency
stays at the correct 1500 Hz or changes to 1140 Hz. Change the
frequency back to 1500 Hz if necessary.
5.
At 10:03, the mode
changes back to MFSK32, with RSID. Observe if the audio frequency stays
at the correct 1500 Hz or changes to 1140 Hz. Change the frequency back
to 1500 Hz if necessary.
6.
At 13:02, the BPSK63F at 360 Hz will end.
Here is the lineup for VOA Radiogram, program 190, 19-20 November 2016, all in MFSK32 except where noted:
1:45 Program preview
2:56 Olivia 64-2000: FUNcube enters amateur service
10:03 MFSK32: China increases Internet control*
17:29 Freedom House global Internet freedom report*
26:34 Closing announcements*
