Yaesu FV 101DM step failure

Postby IK8ZSZ » Fri Jun 03, 2016 7:05 pm

Hi, can anyone help please. My FV101DM don't synthesize 10 and 100 Hz step. On the display I see this step correctly flowing, but on output I have 1Khz step only. I tried to replace all IC on the pll board and all the 74LS90N on the control unit, but nothing. I don't known where come from this steps in control unit and what is the IC that divide the 10 and 100 Hz . ALL other functions are ok.
Tanks for help
