[Elecraft] k2 pll and ref osc issues n0xdb

[Foxjazz]

Hello Elecraft,

  Hello Don,


  I had the pll working before I did phase 3 and put the ssb board in.

  It was working great, now it isn't. I thought I would run a quick
  voltage test before continuing. Now the pll freq is 0.000

  I reviewed the test results and re-tinned T5 just to ensure good
  conductivity.

  When I ran the resistance checks the base resistence of Q6 was at
  372 ohms not 100-140 as the book says.

  the unit turns on draws 0.24 amps

  0.22 without the ssb board in.

  Why would the pll circuit just quit working, would q20 have anything
  to do with it?

  The voltages at q18 are a bit high.





I had the pll vol
