As to this radio, if you get stuck, write notes about it and put it in the radio and set it aside for later review, start on another one.

D2, and D1, D19, D20 are in the front end of the radio before the 1st RX transformer, and are used as PIN diodes for RF Gain and AGC self adjustment. Why would that "Pop" ?
