[sdiy] VCO Sync

[Carsten Toensmann]

Hm, a schematic would really help...

The sync circuits I know 'overdrive' the normal cyclic reset of the VCO 
output voltage. So you have to find this reset point in your VCO first, see 
how it works and then think about a little circuit to add a parallel reset 
(from another waveform, pulse or whatever), I would say. Not really easy 
without schematic.
