If so AEA says to add a .01 MFD Capacitor across D30. D30 is located in lower right hand corner of Main Board, parts pictorial page I-1 of operating manual, just to the left of JP2 and JP3 beside SW-2. I hope this helps, it stopped my problems ...... 73 Rick N7KQB @KE7PV Via W8GRG BBS & WD8SCH - 02/28/89 Cleveland HAMNET File: PK232MOD.TXT
