Hello Firstly Thanks to the guys who responded with their thoughts and
suggestions.

I did in fact take bull by the horns and remove the memory IC and its
socket, I then tossed the socket aside, cleaned up the pins on the IC and
soldered it directly into the PCB.

This so far seems to have stopped the problem, it is still a little twitchy
when I switch it on (Classic FM 100.00 Mhz) starts at 99.95 but within a
minute it changes to 100.00 Mhz and the same for the other stored stations.

So thanks again

Regards
Gary
