[sdiy] EFM News: 3500 Modular - Part 1

[tomg]

Why is it you never see the errors until after you
post something to the world? :)  Can't stop to
fix it right now. It'll have to wait until the full 
version is ready.

The heater for 3542 - VCO is wrong.

R31 2K2
R32 47K
T3 1K

It doesn't say in this doc but after a warm-up 
adjust T3 to match the voltage on pins 2/3 of U5. 

Input resistor 3541 - VCO

R1 - 22K

Tom
