Just to make sure - you do know that broadcast band feature allows you to ignore those bands or your own bands of frequencies in Close Call? So if you add in band 1 a low frequency of 144.00 MHz and a upper frequency of 148.00 MHz, close call will NOT hit on that frequency range. Effectively blocking out anything within that frequency range.
That's why the default bands of TV, Pager, FM, etc are there to block those out so that Close Call does not hit on those frequencies.
