[Elecraft] K3 VFO Tuning noise reduction

[Stewart]

No, you still have the diode and resistor in series.

However as the each of the vias go to pads 15 & 20 of the 
connectors respectively, soldering to the pads is an alternative 
to soldering to the vias.

You can check the continuity with a VOM just to make sure.

Hope that's OK ?

time visualizing this for some reason. Please explain.
