The RCA 16S400 is not a programmable scanner. Rather, it's an old (70's) crystal-based scanner that requires one crystal for each frequency. It covers the VHF-low, VHF-high, and UHF bands, and utilizes Regency type crystals. You can do a Google or Yahoo search for the crystals, but eBay is probably the best, and lowest priced source.
