Radio tests will alsobe done within Iowa between the headquarters at the Starc Armory and otherguard outposts across the Hawkeye State.Colonel King says this is just a test of the Guard’s backup radio system incase computer problems on New Year’s Eve shut down regular communications.Some computer systems may malfunction when the year 2000 arrives as theirinternal clocks may only click over the last two digits to read 1900.
