SSSD 5.25 with 18 sectors pulses Index too slow

[MECCABINGO]

USB Rev D Cased

A 5.25" floppy at 300rpm should generate an index pulse every 200mS
If I create a SSSD Blank floppy with 18 secotors per track, which I think is fine,



I get an index pulse every 400mS.



If I reduce the sectors to 9, it behaves and gives 200mS.

Have I done something wrong, or is the emulator misbehaving?

You need to set the bitrate at 250000 kbits/s. (In FM you need a data bit + a clock bit. So to have a 125000 kbits/s data rate you need to double the bitrate (data + clock))

Many thanks! Good things are happening at 250,000.
