I've loaded a number of frequencies in to my TRX-2 for a road trip to California. When I go to 'Conventional Frequencies', it only shows up Bank 20, even though I have up to Scan List 70 loaded. In the list for LAPD, they use a conventional system but with P-25 modulation. I can't seem to modify what's loaded since I can't seem to get above Scan List 20. Any ideas?
