I occasionally work very close to Aberdeen Proving Ground, and according to the database, they use the Motorola Type II Smartzone analog system. The Primary Control Channels are 409.02500 and 410.15000. I own the Uniden BCD396T, and I am not sure how to program this system into my scanner. I can see the options under:Select System Type: Then I chose Motorola, such as 800 MHz,800 MHz Splinter,900MHz, UHF, VHF, but I am not sure which is correct, since the Primary Control Channels are in the 400 MHz range. Any help is greatly appreciated.
