Re: Calibrating oscillators question

2011-02-22 by sigma.draconis

Today finished the calibrating procedure, and everything was clear.
The only little confusing part was that there was a reference to the VR1 on the KLM-396, because I had the new production board, I couldn't find it offcourse :-)
Guessed it must be VR15 then.

But afterall I got all oscillators in 0,2 cent.
Even the oscillator wich couldn't tune enough before , because I now raised the whole deviation with VR3.

The synth sounds like a charm again, thanks for info and helping :-)
