Eric, First, since the voltage at R30 apparently moves with adjustment of L30, things are working, but the VFO is not at the correct frequency.
First things to check are the capacitors and Varicaps to be certain you have the 'right ones in the right holes'. Look at the RF board schematic sheet 1 of 4 and you will find the VFO and VFO Range Selection components on the upper right corner of that sheet. Verify all the capacitors shown. Be certain D23 thru D26 are the MV209's and D21 and D22 are the 1SV149's - the 1SV149 package looks the smaller of the two when viewed from the top. Then be certain that everything is well soldered, even if that means reflowing the solder on those components. Once you have confirmed that everything above is correct, recheck T5 - it should look like exactly like the diagram in the manual and yes, it has 16 turns of red wire, but be certain you are counting each turn as it passes through the center of the core rather than the outside - also be certain the core is the yellow one. If all the above is correct, it should work FB. 73, Don W3FPR > -----Original Message----- > > I’m on page 61 - VCO Alignment where you "adjust Inductor L30 until the > voltage at R30 reads 6.0 volts" > > L30 is at the top stop and the lowest I can get is 6.3 volts.
