I was seeing a huge parasitic oscillation, around 250 MHz and found that capacitor Cagc was missing, apparently broke off due to poor soldering. You could see some of the solder was still on the pads.I soldered a new capacitor on the board and the unit is now working, but it's very disappointing that I have to troubleshoot and repair the unit myself.
