Page 156 When the strong signal disappears, C1804 and R1809 4-1-10 SSB/CW DEMODULATOR CIRCUITS release the AGC line voltage in CW or RTTY mode to obtain (MAIN UNIT) a fast AGC release time. While in SSB or AM mode, C1803, In SSB or CW mode, the 2nd IF signal from the IF amplifier C1805, R1808 and C1802, R1807 are connected in parallel (Q1601) is mixed with the BFO signal from the PLL unit at to obtain a appropriate AGC characteristics (middle or slow...
