I've been cruising through the assembly manual with no trouble at all until I got to the VCO alignment. I can't get the measured voltage at R30 down below 6.35 volts. I've installed the Rework Eliminator headers and I've set the extended vfo range menu setting D19 to 'Y'. I've double-checked the number of windings on T5 (16 red and 4 green windings), and C72 and L30 read the right value. Here's what I measure. 03500 2.51V 04000 6.35V 07000 2.46V 07300 3.77V 10000 2.77V 10150 3.27V 14000 2.43V 15000 4.03V 18000 2.23V 18200 3.32V 21000 2.19V 21450 2.50V 24800 3.99V 25000 4.35V 28000 3.30V 28800 4.14V The board is assembled with an fine (.018in) solder. The label says it is lead, tin, antimony, and silver with a rosin or zinc cloride core. Does anyone have any ideas what the problem might be? Thanks in advance.
