first snag

KU4YP-2
    hello all,

 

            Well, I hit my first snag with k2 # 5723.

 

            On page 61 of the manual in the vco alignment, I measured the
voltage of r30 first out at 2.33. that was with the tuning slug, L30 turned
all the way in. turning the slug out the voltage changed to 2.44. this is no
where near the 6 volts. My question is, the manual says if the voltage does
not change, refer to troubleshooting. I can't find anything in
troubleshooting that refers to this. With the small change, I am afraid I
will need to rewind t5.

 

            Anyone have the same problem? Words of wisdom in winding t5/

RE: first snag

Hello Mike,
        Don Wilhelm usually sees these requests. Until he sees it try
checking the cap values in the vco circuit mis-interpreting the value is a
source of the symptoms you have. Check soldering, Check soldering, Check
components and then soldering. Check bad soldering/tinning of t5. If there
is a reason that you think t5 is mis-wound then by all means rewind it. If
it is a hunch check the other components and soldering first

Happy Building
