ok im new to this and when i got my scanner radio shack put all my local freq in for me.When i searched on wiki ref in here i found like 10 other frequnciy codes i want to put in for close areas near me,if i put these in manually since theres only 10 will i mess up what radio shack did for me i dont want to delete what they put in.i think i would just put these 10 in a diff bank and then the scanner will scan all am i correct?
