For U.S. Extra exam are any formulas or tutorials online? I need help
with E5C, E5D, E5E, E9C groups for example. I can barely pass the sample
exam now, and would very much like to be able to calculate a few more
answers. I can't get a current exam manual by the test time this
Saturday. All my radio books are ancient or don't cover this stuff
clearly. Thanks.
