4. After transmit is engaged for 30 seconds,5. Adjust each control (R5 and R10) so neither motor tunes while changing from SSB to RTTY and back to SSB.Note:R5 (right) controls right motor and R10 (left) controls left motor.6.

Better yet pull ps out and rewire for externaluse to keep heat out.Replace AM rect diode w schottky for better audio.Increase prod. detector output cap w larger value to get more bass.Adjust audio tone contrl for minimum hisssss.Take out speaker to let heat out-its a killer.Date: 19-01-2002 User comment From: ChrisSubject: More infoThe fl44a is direct replacement for the fl96 stock 765 ssb filter. If one replaces the 9 meg fl30 filter with an fl80 you then havea 2.3 bandwidth filter with outstanding specs per ICOM. All parts are ICOM standard parts, find em used.Another even more important tip is to replace C-280 with a 0.82mf cap (observe polarity if need be)and the agc pops are goneand the IMD per QST of DEC 95 pages 78 to 79 are very relevant.This modification is read 1070 times.top of page
