i was taken aback to discover that once a station is placed in "memory", it can't be deleated. nor can you place a station in memory more than once. so, if you're like me and store a few new stations (not realizing that you could replace a previous station and apparently push it down a space) you find "your" stations below a long list of those placed by the prior owner. has anyone found a way around the inability to delete a previously memorized station?
