[Elecraft] K2 Alignment and Test, Part II - No signal on TP3

[Cameron Haines]

Don,

Great advice. I wasn't able to construct the probe for the frequency counter; missing the capacitor in the kit, either lost it or wasn't included. 

I decided to use a external counter instead. Now, if I simply jumper P6 to T2 and T3, I do get a reading, though sure its inaccurate, but reading nonetheless. I will email Elecraft for missing capacitor. In the interim, do you have a suggestion or replacement cap that will give same or near results until part comes in or another work-around?

Cameron

Cameron,

Read my last post carefully.  Then tell us whether you are seeing all 
zeros when plugged into TP3 and in CAL FCTR.  If you have all zeros, 
either your probe is bad or your PLL reference is not oscillating.

Test up to this point have been good. Checked all the components around X1 and all look correct. No error message on startup.
