MK 178 MODS freq

Hello i build this kit MK178 but the freq (7/s) is to much.
What i mast to modyfi to change the freq to about 3-4/s.

Thanx for help.

I’m afraid this is not possible: AFAICS, all the timing is done in the PIC and clock is internal also. So there is no external way of changing the frequency. But as the schematics are not on the site, I’m only 90% sure.
