JS8Call Now Faster (or Slower)
At the beginning of December, 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||25 Hz||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).
