K2 Part 2 and alignment

hello all,

Part 2 and alignment validated everything is OK, BFO = 5.9 kHz, VCO of 2.17 V to 6.0 V, 13 KHz PLL so it's OK

Song minor or I do not see how pressing the button "display" was the voltage and amperage, the amperage is only Ok, there is a gap between the multimeter reading and that of K2, I not know the origin or the setting of this part

for those that want to place or is the video test::

thank you for your help

Re: K2 Part 2 and alignment

Christophe,

The voltage that you see in the display will always be lower than the
voltage at the input power jack.
There is a reverse polarity protection diode in the K2 and there is a
slight voltage drop across the fuse.
That will make the voltage inside the K2 0.4 to 0.5 volts lower than the
voltage of your power source.

Re: K2 Part 2 and alignment

hello all, hello Don,

thank you for the explanation, it is that I did not think this factor

Thank you, I learn a lot with very interesting list, and big thanks to Don for us to share his knowledge.
