[Elecraft] K3 E 00005 after Synth stiffener install

[Alastair Couper]

I installed the synth stiffener, and now have the following err msgs:

  ERR PL1

  ERR VCO
  E 00005

  ERR VC4
  00255

  V PL1 *0.0

Assuming that it's not about "is unit plugged in?" and "wiggle the plugs",  
which I have done, is there any advice?

I have the sub rx, so I swapped the two PLL cards, and the problem shifts  
to PL2. The working card now in PL1 works fine, and so I'm sure the REF  
osc works.

I tested the plate I installed for continuity to ground, and it shows over  
20Meg ohms. Very quite careful with smoothing the surface. The CAL  
procedure causes the relays to operate, so that much is OK.

Anyone seen this?

Thanks
