Hi,
my name is Steffen and i´m from Germany, near Wilhelmshaven...
i´ve build the hammerhead option2 and now i think i have got a problem
i measured my flyback voltage at Q3 and only got about 70V?
its the maximum i can get, if i adjust width and frequency.
my coil is that of the hammerhead manual. 25cm diameter and 26 turns.
also my pulse seems a little bit disturbed right???
what could be the error? i also recognized, that when i touch parts like C11 R37, the flyback voltage increases.
All other things seem to work, but detector deep is bad, so it must be something to do with the low flyback voltage?!
Regards,
Steffen
