My earlier measurements where taken before U107 was initialized. Also I 
ran thought the "Serial Bus Diagnostics" and everything looks good. Also 
when I change the RF gain, when UHFA is running, the lines that be high 
match the table on the web page. Below are the  measurements from when 
the lines are high and UHFA is running.

QA    5.019    R137    0.963
QB    5.020    R138    0.816
QC    5.011    R139    1.153
QD    4.855    R140    1.448
QE    5.016    R141    4.935
QF    5.017    R142    4.983
QG    5.017    R143    5.007
QH    5.017    R144    5.017

One thing I  noticed was that then the RF gain is 76 or lower QE 
increases 0.004 volts.

Should I being seeing lower voltages at R141 - R144?
