k2 low output

Pat n8vw
My K2 (2016) is suffering low output starting on 20 and wrapping around to
10 and 160 where I get little to no output.  80,40,30 are unaffected.  Rx is
great.  Symptoms include, low output and inability to increase output beyond
a certain level. Both symptons vary per band. When I'm less tired I'll
produce some data.

It sounds like something in the vpwr circuit.  I checked the voltages on U8
and found pin 10 had 5v and 11 had 0v which is opposite of what it is in the
manual.

Thoughts anyone?
