Last weekend’s experiment with center audio frequencies was very useful. We learned that most of you were able to decode MFSK32 using a fixed audio frequency of 1500 Hz, even if the the actual received audio frequency was anywhere from about 10 Hz above or below 1500 Hz. This means that a simple MFSK32 decoding app would not require an RxID.

VOA Radiogram 50, during the weekend of 15-16 March 2014, will be an all-MFSK32 “set it and forget it” show. All of the text and images will be in MFSK32, centered on 1500 Hz. No need to change modes during the show. Here is the lineup:

  1:38  Program preview (now)
  2:33  Internet future
  9:36  Beet juice against ice on highways, with image
17:24  American art at the Phillips Collection, with image
27:42  Closing announcements

This weekend, use your RxID. The RSID for MFSK32 at 1500 Hz will be transmitted at the beginning and about half way through the program. Let me know what your actual received center audio frequency is.

The Mighty KBC

The Mighty KBC, via Germany, will again transmit a minute of MFSK64 Saturday, 15 March, at about 1230 UTC, on 6095 kHz, and Sunday, 16 March, at about 0130 UTC (Saturday 9:30 pm EDT) on 7375 kHz. This will include The Mighty KBC weekend schedule as an Flmsg table. To make Flmsg work with Fldigi, in Fldigi: Configure > Misc > NBEMS – Under Reception of flmsg files, check both boxes, and under that indicate where your Flmsg.exe file is located. At the end of the digital text transmission, you will see the small Flmsg box pop up, followed by the schedule as a new window in your default web browser. Please send reception reports to Eric at themightykbc (at) gmail.com .

Winter SWL Fest

I will be at the Winter SWL Fest, March 14-15, in Plymouth Meeting, Pennsylvania (Philadelphia suburb) to demonstrate the decoding of VOA Radiogram. Information at swlfest.com. Registrations at the door are welcome.
