Don,

Checked D19 is n in the secondary menu.  L30 does change frequency. 
Soldering iron is set to 775F.  I'm using one of those illuminated workbench
magnifying lamps to examine my work.  Even still I reflowed the solder on
all joints to be sure.  U6 circuit components are the correct values and
orientation.  U6 pin 5 reads 4V.  Bridged the pins between L30 and T5 and
resistance is 0.  Checked before bridging and it was as well, but wanted to
be sure.

I am at a loss..

Jeremy
