MK194N does not restore station at pwr on

Hello

Everything works well as long as power stays ON.

I can store stations to the 4 presets, Can switch through the stations perfectly when the radio is on.

However all station presets get lost at power off / on…
Also the station playing at pwr off does not get restored at pwr on.

Also I‘ve noticed that there is no beep when storing the station, just music is briefly interupted, and the station geta stored (for the ON time at least)

I‘ve built the predecessor MK194 - which restores stations perfectly, and noticeably beeps whe stations get stored.

Thanks,
Paul
