VOA Radiogram for 7-8 September 2013
On last weekend’s VOA Radiogram, the experiments with improvements in the RSID generally went well for those of you who had Fldigi 3.21.74AB or newer installed.
This weekend (program 25), we will test the RSIDs again. I have produced the program using Fldigi 3.21.75, so please use that version (or 3.21.74AE, which is the same) for best results. Download from w1hkj.com.
When you have 3.21.75 installed, go to Configure > ID > RsID, and adjust Errors to 0 (zero). This will prevent Fldigi from flipping to another mode when it thinks it hears the RSID for that mode amid the MFSK tones. For more information about this, see http://www.w1hkj.com/FldigiHelp-3.21/ConfigID.html
[This works here. In fact the help at the link recommends a value of 0 on HF. -Hugh]
Please also download the latest versions of Flmsg [1.1.32] and Flamp (2.1.00) from w1hkj.com.
This weekend's VOA Radiogram will include another transmission in MFSK128. This will be done mainly to see if the RSID works. However, to improve the chances for a successful decode of the MFSK128, it will be in Flamp format. A paragraph will be divided into seven blocks of 64 characters each. And it will be transmitted three times, with the second and third passes filling in any blocks with incorrect checksums. Make sure Flamp is running before the MFSK128 transmission begins; it does not turn on automatically like Flmsg.
The foreign language for the weekend will be Spanish, with brief VOA news items in both plain text and Flmsg formatted. Please turn off and restart Fldigi before each of this weekend's VOA Radiogram broadcasts so that the accented Spanish letters display correctly. For the accented Spanish characters to display correctly, use the UTF-8 character set. The adjustment can be found via Configure > Colors & Fonts.
In the Flmsg-formatted Spanish news story, you will see several html codes such as í for the accented characters. They might look like decoding errors, but the story should look OK when the web page renders.
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.
