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?
