Pete, While your VCO voltage range is within spec, it may be worthwhile to make some checks of the capacitors in the VFO range Select area (see the schematic for the capacitors). The Schematic Key has a chart of the capacitors that are used on each band. Of particular interest is the value of C7

I have a couple of questions about the second stage k2 alignment. First is the VCO - Initially, I could only get the voltage at R30 down to about 6.3v with the vfo at 4Mhz. After diddling with t5 winding spacings, I was able to get the 6.0 with some wiggle room in the adjustment (L30 will adjus
