Note new NA local times for VOA Radiogram March 18-19

From Kim Andrew Elliott:

Hello friends,

Now that most of North America has changed to Daylight Savings Time, most Americans and Canadians will hear VOA Radiogram one hour later by local time. This is because VOA Radiogram stays at the same UTC time year round. The same will happen for European listeners beginning 26 March. 

Also that last weekend of March, many shortwave broadcast stations will change some of their frequencies to correspond with seasonal shifts in propagation. The only change for VOA Radiogram from North Carolina is that the Saturday 0930-1000 UTC broadcast will move from 5865 to 5745 kHz, effective 1 April.

Effective 26 March, IBC (Italian Broadcasting Corporation) will drop its 3975 kHz frequency for the summer. IBC will no longer broadcast VOA Radiogram. There might be one more VOA Radiogram via IBC, Wednesday, 22 March, at 2100-2130 UTC, on 3975 kHz.       

This weekend’s VOA Radiogram will be all MFSK32, except for one item in MFSK16, in case reception is difficult.

Here is the lineup for VOA Radiogram, program 207, 18-19 March 2017, all in MFSK32 except where noted:

  1:46  Program preview  
  2:56  Fog-clearing apparatus used at Oregon airport*
  9:52  'Boaty McBoatface' submarine to embark on first mission*
 16:44  MFSK16: RFE/RL photo archive from 1950s USSR
 21:50  MFSK32: Images* and closing announcements

Italian Broadcasting Corporation (IBC)  For the complete IBC transmission schedule, including changes after 27 March, visit  http://ibcradio.webs.com/  The new English version of IBC’s “Shortwave Panorama” begins  31 March, via WRMI Florida, Friday 01.00-01.30 UTC on 9955 kHz, Saturday 01.30-02.00 UTC 11580 kHz, and
Sunday 00.30-01.00 UTC on 7730 kHz. The last five minutes of these shows will be in MFSK32.


Thanks for your reception reports from last weekend. In comparison of the two 58-wpm modes, MFSK16 and Olivia 8-1000, it appears that MFSK16 performed better, based on most reports.

Due to commitments related to my audience research work at VOA, I am vastly behind in answering your reports, but I hope to get back on track this weekend.

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

PS: A few operating notes:
  • For best Olivia 64-2000 performance, turn Fldigi's squelch (SQL) off.
  • The RSID at 1500 Hz sometimes mixes with the transmitter hum, most noticeable at 360 Hz, to move your receive audio frequency down to 1140 Hz, resulting in no decode. To prevent this, in Fldigi: Configure > IDs  > RsID > unselect Searches passband.  Your center audio frequency will wander no more than +/- 200 Hz.
  • Fldigi automatically saves your decoded MFSK images as png files in the folder \fldigi.files\images\ (in Windows; folder names might be different with other operating systems). You can attach those png files with your reception report.
  • The VOA Radiogram Twitter account @VOARadiogram is especially active before, during, and after the broadcasts. You don't need a Twitter account: just go to https://twitter.com/voaradiogram and refresh it occasionally.

New pchfdl.dat File Uploaded to Web Site

Since the HFDL ground stations were sending out the new HFDL System Table quite frequently to airplanes needing it, my PC-HFDL was able to update itself and generate the new pchfdl.dat file.  Those who miss getting a live uplink from a ground station can grab it on this column's web site, as always.

NOTE: I generated it here, and it works just fine on my computer.  I can't guarantee anything for anyone else. This is why it's necessary to rename the old pchfdl.dat, not delete it.

You may not need it yet!  I've noticed that several ground stations are still using table #49 as of mid afternoon on Pi Day.  If pchfdl.dat is replaced, these stations will show the numbers instead of frequencies.  The new file is for System Table #50.


HFDL System Table 50 in effect

San Francisco and some other HFDL ground stations have been using System Table 50 as of this morning (local time). This replaces Table 49, which had been used for quite a long time.

No PC-HFDL update file yet, but here it is in squitterese:

VOA Radiogram for 11-12 March

From Kim Andrew Elliott:











Hello friends,

Apologies for the mix-up in the images transmitted last weekend. I was in too much of a hurry while preparing the VOA Radiogram demonstration at the Winter SWL Fest. It was good to meet some of you there!

Two weeks ago, we were impressed with the performance of the MFSK16 mode in difficult reception conditions.  We will include MFSK16 again this weekend, but we will compare it to another 58-wpm mode, Olivia 8-1000. The same AP news story will be sent in each mode. Note that MFSK16 is 316 Hz wide, while Olivia 8-1000 is 1000 Hz wide. After the RSID for each mode will be a 15-second tuning signal, in case you need to manually set the mode and/or center audio frequency.

Here is the lineup for VOA Radiogram, program 206, 11-12 March 2017, all in MFSK32 except where noted:


 1:51  Program preview (now)
 3:09  China seeks international law for Internet control*
10:07  North Korea bans overseas citizens from mobile Internet*
18:18  MFSK16: Satellite maps lightning flashes
21:55  Olivia 8-1000: Satellite maps lightning flashes
25:18  MFSK32: VOA tweet on International Women's Day*
27:15  Closing announcements

Thanks for your reception reports from last weekend, especially because I was not able tune in to most of the broadcasts while attending  the Winter SWL Fest (and because of terrible shortwave reception in my hotel room).

I'll try to get back on track this weekend responding to your reports.


I hope you can tune in (especially because I may not be able to) and write in this weekend.

VOA Radiogram for 4-5 March

From Kim Andrew Elliott:

Hello friends,

I'm sending this note early this week, as I prepare for the Winter SWL Fest Thursday through Saturday at Plymouth Meeting, Pennsylvania, near Philadelphia.  For the  same reason, we'll keep this weekend's program simple, with MFSK32 as the only mode.

Speaking of the Winter SWL Fest, on its agenda is the Shortwave Shindig, which will be broadcast live on WRMI, 6855 kHz, Saturday 0300-0600 UTC (Friday evening in North America). Host David Goren, of Shortwaveology, plans to include one or two MFSK32 images during the show.

Please also note that The Mighty KBC will transmit on 6040 kHz, in addition to its usual 6145 kHz, Sunday 0000-0200 UTC (Saturday 7-9 pm EST). This is because of an interfering signal just above 6145 kHz. A minute of MFSK32 will be at about 0130 UTC.

Here is the lineup for VOA Radiogram, program 205, 4-5 March 2017, all in MFSK32:

 1:49  Program preview
 2:54  Cambodia threatens media outlets*
12:31  Foreign TV blocked for North Koreans in China*
19:28  Few complain after ABC drops shortwave
23:26  Dubai amateur radio satellite*

Thanks for your reports from last weekend. Our experiment with MFSK64, 32, and 16 was very interesting, with MFSK16 performing very well in poor reception conditions.

Because of preparations for the Winter SWL Fest, and attending it, there will be some delay in answering your reports. Apologies for that and thanks for your patience.

I hope you can tune in (especially because I may not be able to) and write in this weekend.
