True, being a radio nerd causes a smirk at many a 'wrong time'. Decades ago, while watching some grade B action flick, allegedly in Vietnam, the 'radioman' was calling and calling into his manpack "radio". In panic he declares: "It's no good...nobody hears us!'. I'm chuckling because hanging out the top of his ruck was his "radio"; a .50 caliber ammunition can with a magmount antenna on it. ha ha
'Ain't no one gonna hear you with THAT, Son !'
Well, at least it would not be effected by an EMP, and no batteries necessary.
