Best settings for HH

[Pilot68]

Hi,


i'm new here, my name is Jörg but George is also ok ;-)

I like this tech forum very much and at the moment im building up three Hammerheads for me and some friends with a self-routed PCB.

Has anybody tested out the best setting for frequency, delay times and pulse times? I think it should depend on some factors (coil etc.). But many other designs seems to use fixed parameters, only threshold, gain and volume are controlled by user.

I ask this for a future project, in wich i want to let a µProcessor set the times. non-VCO and VCO-mode as like as single- and difference-mode will also be switchable in this project.

And a question to Carl:
(first let me say: great work !)
Is there any significant difference between the Rev1.4 and Rev1.5 documentation, because i startet with Rev1.4?

Thank you all, and sorry for my bad english, i'm a german...

There were only some minor error fixes in 1.5, I think.
