I also have a PCB with two CEM VCO's. They also had an interference
problem. It disappeared when I ran each VCO from a separate supply line
from the same power supply.
Try to run a separate supply line from the power supply to each single
module, don't chain supply lines, use separate wires directly from the
power supply, hope this helps.
