 This shows the level of the signal entering the FT8 demodulator and decoder and peaks (shown by the tiny red vertical bar) should never exceed 100%. In fact there is a 10% guard so 100% is actually 90% of the signal volume. Note that the decoder will work well even with a few % volume however you should try to set the volume (A.10) so that big signals reach at least ~20% to have the best dynamic range.

   - ShNI: this is the same as above but with non interleaved frames.
   - HSkip: this is the horizontal sync skip technique for vertical synchronization. This has been in use in the first TV experiments with a small number of lines. This method just skips one horizontal synchronization pulse to mark the last or the first line (here it is the last). This method does not use any full line for vertical sync and all lines can be used for the image thus it suits the modes with a small number of lines. With more lines however the risk of missing pulses gets higher in adverse conditions because the pulses get shorter and may get swallowed by a stray pulse or a stray pulse can be taken for a valid one. In this case two images might get out of sync instead of just two lines. In practice this is suitable up to 90~120 lines.

 The refresh period is limited anyway by the FFT period which is the FFT size divided by the baseband sampling rate and multiplied by the fixed average or max size (3A.5) in case these features are engaged (3A.4). Setting a resulting FFT refresh time above the refresh rate will make sure that a short burst is not missed particularly when using the max mode.
