All posts for the month Febbraio, 2017

Hello friends,

Happy World Radio Day!  World Radio Day will be Monday, 13 February, and it will be mentioned this weekend on VOA Radiogram.

Also this weekend, we will transmit samples of text in Chinese, Russian, and Persian. For these alphabets to display correctly, Fldigi should be configured to the UTF-8 character set (Configure > Colors & Fonts > adjust Rx/Tx Character set to UTF-8, if it is not there already). Your operating system might also need font support for non-Western languages. If the Chinese, Russian, or Persian text is seen as a series of boxes in the Fldigi receive pane, copy and past those boxes to a word processor, and the text might display correctly. At the bottom of this email is a picture off what the received text in the three languages should look like.

There will be four MFSK32 images this weekend, but they will not be transmitted until the second half of the show.

Here is the lineup for VOA Radiogram, program 202, 11-15 February 2017, all in MFSK32 except where noted:

 1:45  Program preview
3:05  China to vet online content and services

10:17  Olivia 64-2000: ESA to help NASA

Winter SWL Fest.  I am planning to attend the Winter SWL Fest, March 2-4, 2017, at Plymouth Meeting, Pennsylvania, near Philadelphia. Hope to see you there. Information at  http://www.swlfest.com .

 

Thanks for your reports from last weekend. (Or, if you are in Europe and tuned in Sunday at 1930 UTC on 15670 kHz,  reports of attempted reception.) Now that I’ve finally responded to the reports from program 198, I’ll start with the program 201 reports and work backwards.

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.
