[Elecraft] PLL Reference Oscillator Range and VCO Test

[Dickie M0AUW]

Hi Don,
Many thanks for your quick reply. 

U5 pin 7 good 4.8v at + 0 at -
U6 pin 1 good 7.68v at + 0 at -
D16 and 17 checked, same voltage change as U6 pin1
Q19 I'm getting a reading of 257 ohms
C84 and 85 are checked and correct

While I had the time I removed the thermistor board , all looked OK. 
I will double check RFC14 and if necessary rewind and re-tin; I will also go
over all the soldering again, 9 times out of 10 its a bridge or a soldering
issue but I have to say I can't locate anything yet.
Will let you know how I get on

73s - Dick M0AUW
