Gang:
Still verifying the parts installed on the board...
Interesting Things Found so far:
Looks like the driver collector tank is connected wrong...
Center tap to trimmer instead of collector and hi end to
collector instead of trimmer.... The schematic shows it
correctly, but the parts installation/layout diagram doesn't
make it clear which leads go where.... Gonna FIX that...
(Or break it, heaven forbid..)
Driver transistor not the one specified. A 2N2222A (which is
shown in the chart on the schematic) is in there.
However, the "top most" "late breaking news" note sheet
(handwritten) says that a 2N3866 or 2N5107 is used...
The emitter resistor for the 'new' devices is 15 ohms where
the old one was 47 ohms... Old device with new emitter
resistor... Don't know if it matters... We'll see...
The VFO tuning cap has two connections to the board besides
the ground connection. That's because all of the onboard VFO
circuitry is not in one place, but in two places far apart on the
board. You need two wires from the stator to get to these two
pieces of circuitry. This is not real obvious from the instructions,
although the board diagrams in fact show both connections if
you look closely. If you leave off one of the connections you
don't have your cap connected to the NE602, and
don't have RX ot TX injection!!...Makes for the severe quiets....
End of verification in sight...Looks like maybe power on tomorrow...
Everybody keep their fingers crossed...
Oh yeah....GOT THE FOX!! Real mini pileup right under some QRO
QSO. Interesting... Sounded like lots of takers.
More later...

No takers on 1/2 turns on toroids huh??
