New this weekend is the elimination of the digital text modes from shortwave transmitters in Germany.

The German regulator Bundesnetzagentur has ruled that the digital modes are not allowed in the broadcast bands. Because of this, there will be no MFSK32 on The Mighty KBC this weekend, because it uses a transmitter in Nauen, Germany.  And, for the time being, there will be no DigiDX MFSK broadcasts on Channel 292, 6070 kHz, and Radio 700, 3985 kHz.

Listeners in Germany might want to note these arguments for the digital modes on the shortwave broadcast bands: 1) It is broadcasting, not point-to-point communication. 2) It can be received on any shortwave radio, even inexpensive portables with no SSB capability. (Software is required to decode the text and images, but this can be included in future shortwave radios.) 3) DRM is legal on the shortwave broadcast bands, and DRM can transmit text and images.  4) Text and images via analog radio requires less spectrum (bandwidth) than DRM. 5) Text and images via analog radio are a useful new application for underutilized shortwave transmitters and frequencies. 6) Text and images via analog radio extend the range of a shortwave transmitter, resulting in accurate content in conditions where voice transmissions may be unintelligible. 7) Digital modes via shortwave can be a useful alternative when the Internet is not available due to disasters or to net censorship by dictators.

VOA Radiogram, program 157, 2-3 April 2016 is all MFSK32 except for the transmission schedule in Olivia 64-2000 under the closing music:

Digital modes on The Mighty KBC (via Germany) and DigiDX (via Channel 292, 6070 kHz, and Radio 700, 3985 kHz, both via Germany) will not be available this weekend for reasons stated above. DigiDX will be available via WRMI, Florida, Sunday at 2130-2200 UTC on 15770 kHz and 2330-2400 UTC on 11580 kHz.

Propagation last weekend was difficult on Saturday, especially within North America. Fortunately, it improved by Sunday.

If you are new to the program, note that Fldigi automatically saves decoded images as png files in the folder \fldigi.files\images\ probably within your C:\Users hierarchy. Operating systems other than Windows may have different folder names. When sending reception reports, please attach those png files.

In most of the United States and Canada, VOA Radiogram is now one hour later by local time because of the change to daylight time. The UTC times remain the same (see schedule below). Effective 2 April, the Saturday 0930 UTC broadcast changes to 5745 kHz.

VOA Radiogram this weekend will include an 8-minute stretch of Olivia 64-2000. Let’s hope for poor reception – or create poor reception conditions – to give the Olivia 64-2000 a workout.

VOA Radiogram reception and decodes were very good last weekend. Here’s an example by Alessandro in Italy, 13 March 2016, 1930-2000 UTC, 15670 kHz:

VOA Radiogram this weekend will be all MFSK32 except for a brief transmission of Olivia 64-2000 at the end of the show.

Another “twist” will be some Chinese text. For the Chinese text to display correctly, in Fldigi: Configure > Colors & Fonts >   Rx/Tx Character set. (I believe that UTF-8 is the default on TIVAR and AndFlmsg.)

The future of this KBC broadcast to North America is uncertain. KBC will end its broadcast Sundays to Europe on 6095 kHz on 27 March due to a lack of sponsors.

DigiDX MFSK32 (and possibly also MFSK128L) transmissions will be active this weekend, as follows:

VOA Radiogram this weekend is all in MFSK32. There is no time for a slow mode such as Olivia 64-3000, because the MFSK32 stories are too interesting to cut.  

Here is the lineup for VOA Radiogram, program 153, 5-6 March 2016, all in MFSK32:

The Mighty KBC will transmit a minute of MFSK32 Sunday at about 0220 UTC (Saturday 9:20 pm EST) on 6040 kHz, via Germany. Yes, I know this conflicts with the DigiDX transmission this weekend. We will try to harmonize the digital mode schedules in future weeks. Reports for KBC reception and decode to Eric: themightykbc (at) gmail.com .

DigiDX is a new service providing DX news in MFSK32 via Channel 292 in Germany, 6070 kHz, 10 kW.  The DigiDX test transmissions last weekend were mostly successful despite China Radio International and other stations on the same frequency at various times.  

DigiDX MFSK32 transmissions will resume this weekend via Channel 292, 6070 kHz. One will be Sunday at 0200 UTC (Saturday 9 pm EST), with possible reception in the Americas. The other will be Sunday at 1100 UTC. You might hear DigiDX MFSK32 transmissions at other times during the weekend on 6070 kHz, and possibly via Radio 700 on 3985 kHz. Consult the DigiDX Facebook page, https://www.facebook.com/digidx , and its Twitter account, https://twitter.com/Digi_DX .    

Jari in Finland had a good decode of DigiDX despite a SINPO 55555 signal from China Radio International on the same 6070 kHz frequency …
