-====== JS8Call Now Faster (or Slower) ====== 
  
-At the beginning of December, [[http://js8call.com/ |JS8Call]] released their version 2.0, adding two faster transmission speeds (//Fast// and //Turbo//).  This week, 2.1 was released, adding a //Slow// speed that can work in even weaker SNR conditions.  
- 
-^Mode   ^Bandwidth ^Speed  ^Frame Length  ^Mininum SNR ^ 
-|Slow | ?          |8 WPM | 30 seconds |-28 dB | 
-|Normal |50 Hz     |16 WPM |15 seconds    |-24 dB | 
-|Fast   |80 Hz     |24 WPM |10 seconds    |-20 dB | 
-|Turbo  |160 Hz    |40 WPM |6 seconds     |-18 dB | 
- 
-The new MULTI decoder can decode all four speeds at once. 
- 
-A few weeks ago, I gave it a quick spin and got copied on "Turbo" by a station near Boston at -13 dB on 80 m (at 22:30).
