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

[Cameron Haines]

Good morning,

I finally have my probe setup. Here is my readings which seem way off.

4 Mhz Oscillator Calibration = 1817.00 which should be reading 12090 +/- 30 kHz per manual

PLL Reference Range Test

Seems correct range but frequency is wrong as with Osc calibration.

VCO Test
 
3 - 4 kHz as opposed to 8 - 10 Mhz.

Any thoughts were I have gone wrong?

Thanks,
Cameron

Great suggestion. I can hear it a 4Mhz now.. from my Softrock SDR. Wonder why the Freq counters couldn't pick it up however. hmm.

Thanks David!

Do you have a receiver you can listen on to see if the oscillator is actually oscillating?

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