face="Times New Roman">Following the troubleshooting guide on the Penelope Wiki,
I measured 300 mV at pin 2 of JP3. If I remover the jumper I measure 600 mV. The
VFWD voltage (pin 7 of UB9) measures 1.25 Vdc. Is this dc level too high
resulting in the FPGA code to reduce the output? In other words, could the low
output power be the result of a feedback condition (related
to U9 or U7) causing the power to roll back? </FONT></FONT></P>
