Thanks for the info offer .I am a babe in the woods with the Arduino and put the post up to see if it is feasible before I try to learn how to do it with an SD Card. As it seems it may be OK to use the eeprom I will explore that first. I am hoping to find a way to store frequencies that can be recalled, maybe with a channel change switch?
At this stage of my learning I am just having fun listening around and doing some simple sketch mods.
