VCO Alignment

[Gary Scott-3]

Hi Gang
  Im building K2 4988,and on Alignment and test part 2 / VCO
alignment, I could not get L30 adjusted to 6 volts on R30, Started
rechecking my work as per directions,everything was fine,so directed
my attention to T5,adjusted the spreadings of T5 and was able to get 6
volts at R30,My question is should I rewind T5 ,or just leave T5 alone
and move on?
 Thanks W4GNS

If you can get 6 volts at 4 MHz and if all the other band edges are
within range as specified in the manual, then you do not need to rewind
anything, you are all set!

Gary,

If it is OK now, don't 'fix' it any more.

If the end points for all the bands fall between 1.0 volt and 7.5 volts (1.5
to 7.0 volts is even better, but not achievable after installing the K60XV),
all will be well.  If you have some out of that range, you may want to
re-wind T5, but spreading/squeezing the turns is a valid method of
adjustment.
