[sdiy] Attn: CRYSTAL - EFM VCF1e questions

[vitreousflux]

Hi Crystal, Harry recommended you as someone who's built and used the VCF1e
module.

Can I ask you a few questions?

I have one built and can't get the 2-Pole to work. I get only dry signal out
of LP, and no signal out of BP and HP

OK so say I have an input on wire F that has a ~60Hz sawtooth.

After the first 100K resistor, there is no original signal, just a 125Khz
sine
wave (WTF??)

The resistor tests ok by itself.

I have checked all my wiring with continuity and scope, all seems ok but
since my source signal is lost after the 100k resistor, it ain't workin'.

The 1-pole works great.



Thanks much for your time!

Rob
