I have programend the freqs in the bank set them to mot and i can hear what appers to be the schp but instead of greenville I am hearing for saprtanburg. Could someone please send me a screenshot or a link or some way to program The SCHP for Greenville. I would also like to have Pickens/oconee. Is there a place to program the 20880 for greenville? I may be in way over my head....I am using win 97 and a pro 97 Plus sometimes it locks on one of the freqs and all I hear is a grrrrrrrrrrrrrr noise, what is that?
