Last week's VOA Radiogram was interesting. On the higher frequencies, copy of the long-interleave MFSK and the Thor100 was good. On the lower ones, which had better signal strength but also more noise, they produced gibberish, and 8-bit UTF-8 gibberish at that. Same location, receiver, software, and antenna for both, of course.
This week looks interesting again.
From Kim Elliott:
Hello friends,When we last transmitted Chinese characters on VOA Radiogram, we noted that they printed out more slowly than English letters. This is no doubt due to the greater complexity of the code involved with non-Latin alphabets. This weekend we will transmit Chinese characters in MFSK32, then try to speed it up with MFSk64. Make sure you have Fldigi set to the UTF-8 character set.We will also continue our experiments with the new long-interleave modes MFSK64L and MFSK128L.Here is the lineup for VOA Radiogram, 16-17 November 2013 (produced using Fldigi 3.21.77 and Flmsg 1.1.33, both available from w1hkj.com):NEW: Left column shows time into the program.
